The Avaya 3605 exam, officially titled "Avaya Communication Server 1000 R7.5 Operations and Maintenance," was a key certification for technicians and administrators responsible for the day-to-day management of this robust enterprise telephony platform. This exam served as a benchmark, validating that a professional possessed the essential skills to operate, maintain, and perform basic troubleshooting on a CS1000 system. The certification was aimed at individuals working in roles such as telecommunications support, system administration, and field service engineering. It demonstrated a comprehensive understanding of the system's architecture, its administrative interfaces, and its core features.
While the Communication Server 1000 has its roots in the Nortel Meridian 1 and is now a legacy platform, the principles of telephony and system administration covered in the 3605 Exam are foundational. Understanding the material provides deep insight into the architecture of a large-scale, reliable voice communication system. For professionals who still support these systems or for those interested in the evolution of enterprise voice technology, studying the topics of the 3605 Exam offers valuable knowledge about the building blocks of modern unified communications.
A fundamental requirement for the 3605 Exam is a solid understanding of the Communication Server 1000 R7.5 architecture. This system is built upon a distributed model that separates the core call processing functions from the IP-based signaling and management functions. The two main components that embody this separation are the Call Server and the Signaling Server. The Call Server is the traditional heart of the system, running the core real-time operating system that handles all the call features, routing logic, and control of the traditional TDM (Time-Division Multiplexing) hardware.
The Signaling Server, on the other hand, is based on a standard Linux platform and manages all the IP-centric elements of the system. This includes the registration and control of IP phones, the management of SIP (Session Initiation Protocol) trunks, and the hosting of the primary web-based management interface, Element Manager. This dual-server architecture allowed the CS1000 to bridge the worlds of traditional digital telephony and modern Voice over IP (VoIP), a key concept for the 3605 Exam.
Despite its evolution towards software, the CS1000 R7.5 still relies on a robust set of hardware components, and their identification and function are a core part of the 3605 Exam. The system is housed in cabinets, with the main cabinet often referred to as the IPE (Intelligent Peripheral Equipment) shelf. The core processing power resides on specific cards. The most important of these is the Call Processor card, such as the CP PM, which contains the CPU and memory that run the main call processing software.
To handle audio processing, such as for conferencing or tone generation, the system uses Digital Signal Processing (DSP) resources, which are often located on daughterboards that plug into other cards. To connect to the actual telephones and outside lines, the system uses a variety of peripheral cards. These include Digital Line Cards (DLC) for connecting digital phones, Analog Line Cards (ALC) for standard analog devices like phones and fax machines, and various trunk cards for connecting to the public telephone network.
The Call Server is the brain of the CS1000 system, and a deep dive into its function is essential for the 3605 Exam. It runs a proprietary, real-time operating system that is highly optimized for the demands of call processing. This software is responsible for executing all the telephony features that users interact with daily, such as call hold, transfer, conference, and voicemail integration. It also contains the routing and trunking logic that determines how calls are sent to their destinations, both internally and externally.
The core software is organized into a series of loads, which are essentially software modules that can be loaded into memory to provide specific functionalities. The health and integrity of this core software are paramount for the system's stability. A key task for an administrator is to perform regular system backups and to know how to check the status of the software and hardware components to ensure everything is operating correctly. The 3605 Exam tests these fundamental operational concepts.
The Signaling Server represents the modern, IP-focused side of the CS1000 architecture. Its role and management are a critical topic for the 3605 Exam. Unlike the Call Server's proprietary operating system, the Signaling Server runs on a standard, hardened Linux platform. This provides a familiar environment for many IT professionals and allows for standard management practices. The primary function of the Signaling Server is to act as a gateway and controller for all IP-based endpoints and services.
It manages the registration and signaling for all the Avaya IP phones, controls the SIP trunks that connect to VoIP service providers, and hosts the applications that are essential for system management. The most important of these applications is the Unified Communications Management (UCM) suite, which includes the Element Manager. A support technician must be comfortable with the basic Linux command line for troubleshooting and be able to manage the services that run on the Signaling Server.
For most day-to-day administrative tasks, the primary tool is the Element Manager. Proficiency in navigating and using this web-based graphical user interface (GUI) is absolutely mandatory for the 3605 Exam. The Element Manager is accessed by browsing to the IP address of the Signaling Server. It provides a structured and user-friendly way to manage all aspects of the system, from users and telephones to routing and system-wide parameters.
The interface is typically organized into a navigation tree on the left, which allows you to select different functional areas. The main pane on the right then displays the configuration options for the selected area. Common tasks performed in Element Manager include adding, modifying, or deleting a telephone; changing a user's features; and configuring trunk routes. The 3605 Exam will often present scenario-based questions that require you to know exactly where to go in the Element Manager to perform a specific administrative task.
While Element Manager is the modern GUI, the traditional command-line interface (CLI) remains an incredibly powerful and efficient way to manage the system. A solid understanding of this CLI, known as overlay programming, is a major component of the 3605 Exam. The CLI is accessed via a terminal session (using SSH or a serial connection) to the Call Server. The system's software is organized into programs called Overlays or Loads, which are identified by a number (e.g., LD 20 is for programming telephones).
To work on a specific configuration area, you first load the corresponding overlay. Once in the overlay, you use a specific syntax of commands, prompts, and responses to query, print, and change the system's data. For example, to print the details of a telephone, you would go to LD 20, use the PRT command, and then specify the type of information you want to see. This command-line access is essential for advanced troubleshooting and for scripting repetitive tasks.
The core database of the CS1000 is often referred to as the Customer Data Block, or CDB. A conceptual understanding of how it stores user information is a key topic for the 3605 Exam. The CDB contains all the detailed configuration data for every element in the system. When you program a telephone, you are essentially modifying records within the CDB. A key part of this database is the Numbering and Addressing Map, or NAM.
The NAM is responsible for mapping a telephone's directory number (DN), which is what users dial, to its physical or logical location in the system. This location is identified by a Terminal Number (TN). The TN is a hierarchical address that specifies the physical hardware (Loop, Shelf, Card, and Unit) where a digital phone is connected, or the logical address for an IP phone. The 3605 Exam will expect you to understand this fundamental relationship between a DN and a TN.
To effectively provision and troubleshoot hardware, an administrator must understand the physical hierarchy and addressing scheme of the CS1000 system. This is a practical knowledge area covered in the 3605 Exam. The system hardware is organized into a clear structure. A Loop is a high-capacity fiber optic or copper link that connects the main system cabinet to expansion cabinets, allowing the system to grow. Each cabinet, or shelf group, contains one or more card Shelves.
Each Shelf has a number of slots where the peripheral cards are installed. The physical address of any port on a card is defined by its Loop, Shelf, Card, and Unit number. For example, a Terminal Number (TN) of 12 0 4 1 would refer to Loop 12, Shelf 0, Card 4, and Unit 1 on that card. This precise addressing scheme is used throughout the system's programming to identify specific hardware ports, and being able to interpret it is a fundamental skill.
Success on the 3605 Exam begins with a complete mastery of these foundational topics. The exam is designed to test your practical, operational knowledge. You can expect questions that require you to identify the primary function of the Call Server versus the Signaling Server, or to name the specific hardware card required to connect a certain type of device. You will also see questions that require you to choose the correct administrative tool (Element Manager or a specific CLI Load) for a given task.
To prepare effectively, focus on the "why" behind the architecture. Understand why the call processing is separated from the IP signaling. In a lab environment, if possible, spend significant time navigating both the Element Manager and the command-line interface. The ability to quickly locate information and understand the hierarchical structure of both the physical hardware and the software configuration is essential for building the confidence needed to pass the 3605 Exam.
The Terminal Number, or TN, is one of the most fundamental concepts in the CS1000 system, and a deep understanding of it is absolutely critical for the 3605 Exam. The TN is a unique address that identifies a specific port or endpoint in the system. It serves as the primary key for all the configuration data associated with a telephone set. Every feature, key assignment, and class of service for a phone is linked to its TN. The TN represents the bridge between the physical or logical endpoint and its programming in the Customer Data Block (CDB).
The structure of the TN is hierarchical, representing the physical hardware layout: Loop, Shelf, Card, and Unit. For IP phones, which do not have a direct physical card slot, the TN is a virtual address that still follows a similar structure. This consistent addressing scheme is used throughout the command-line interface for programming and troubleshooting. The 3605 Exam will require you to be able to interpret TNs and understand their central role in the system's database.
One of the most common administrative tasks is adding a new telephone to the system. The ability to perform this task using the Element Manager is a practical skill tested on the 3605 Exam. The process involves navigating to the 'Users and Services' section of Element Manager. You would typically use a wizard-like interface to create the new station. The process begins with selecting an available Terminal Number (TN) on an appropriate digital line card.
Once a TN is selected, you must define the key characteristics of the new phone. This includes specifying the model of the telephone set, assigning it a primary Directory Number (DN), and giving it a display name. You will also need to configure the keys on the phone, assigning functions like line appearances, features, or speed call numbers to each button. Finally, you assign various classes of service that control the phone's permissions and features. The 3605 Exam will test your familiarity with these sequential steps.
While Element Manager provides a graphical way to build phones, the 3605 Exam also requires proficiency in using the command-line interface (CLI) for the same task. The primary overlay for station administration is Load 20 (LD 20). To build a new phone, you would first access LD 20. The command to create a new station is NEW. The system will then prompt you for the key information in a specific order. The first prompt is TYPE, where you specify the model of the phone.
The system will then guide you through a series of prompts, asking for the TN, the DN for the first key, and other essential parameters. You will need to know the specific prompt mnemonics, such as CLS for Class of Service and NAME for the user's name. This method is faster for experienced administrators and is essential for making bulk changes or for troubleshooting when the GUI is unavailable. The 3605 Exam often includes questions that require you to interpret or complete a sequence of commands from LD 20.
When programming a station, either in Element Manager or the CLI, you will encounter several critical configuration parameters. A thorough understanding of their meaning is required for the 3605 Exam. The CLS (Class of Service) prompt is one of the most important. This setting controls what the telephone is allowed to do. For example, it determines if the phone can make long-distance calls, forward calls, or use specific advanced features. There are numerous class of service options that can be allowed or denied.
Another key area is the key programming. For each button on the phone, you must define its function. This could be a KEY followed by a DN to make it a line appearance, KEY followed by a feature code (e.g., CFW for Call Forward), or KEY followed by SCL for a speed call list. The HUNT prompt is also important, as it is used to make a DN part of a hunt group, allowing multiple phones to be rung in sequence. The 3605 Exam will test your knowledge of these fundamental programming elements.
Classes of Service, or CLS, are the primary mechanism for controlling a user's access to telephony features and dialing privileges. A deep understanding of how CLS works is a major topic for the 3605 Exam. The CLS is a set of flags or options that can be either allowed (X) or denied (F) for a specific telephone. These settings are defined in the Customer Data Block and are assigned to each station via the CLS prompt in its configuration.
There are many different CLS options. For example, CLSA (Class of Service Unrestricted External) allows a phone to make any type of external call. CFXA (Call Forward External Allowed) permits a user to forward their calls to an outside number. By creating different combinations of these allowed and denied features, an administrator can create different service profiles for different types of users, such as executives, standard office users, or lobby phones. The 3605 Exam will expect you to be able to identify the correct CLS to enable or disable a specific user feature.
The process of programming an IP phone in the CS1000 system has some key differences from programming a digital phone, and these are important to understand for the 3605 Exam. While a digital phone has a physical TN tied to a specific card slot, an IP phone uses a virtual TN. The creation process still involves defining a TYPE (e.g., 2007 for an Avaya IP Phone 1140E) and a virtual TN within the IP phone programming overlay (LD 11).
The most significant difference is that the IP phone's identity is tied to its MAC address. For an IP phone to register, its MAC address must be associated with the programmed TN. This is done through a process of registration or by manually entering the MAC address in the system's configuration. The IP phone then communicates with the Signaling Server to receive its configuration file and register, after which it can place and receive calls via the Call Server.
The day-to-day work of a telecom administrator is often summarized as MACs: Moves, Adds, and Changes. The 3605 Exam requires proficiency in all three of these activities. An "Add" is the creation of a new telephone set, as described in the previous sections. A "Change" involves modifying the configuration of an existing set. This could be as simple as changing a user's name or as complex as reprogramming all the keys on their phone. Changes are typically done in LD 20 using the CHG command or via the modification screens in Element Manager.
A "Move" involves relocating a telephone from one physical location to another. For digital phones, this can be a physical move, where the phone is unplugged and plugged in elsewhere, and the programming on the old and new TNs must be swapped. For IP phones, a move is much simpler, as the phone's programming is tied to its MAC address, not its physical location. The user can simply plug their phone into any active network port, and it will register with its correct configuration.
Beyond standard user telephones, the CS1000 supports specialized set types for specific functions. A high-level understanding of these is relevant for the 3605 Exam. Automatic Call Distribution (ACD) sets are used in call center environments. ACD agents log in to these sets to become available to receive customer calls. The programming for an ACD set includes defining the ACD skills (or queues) that the agent will be a part of.
Attendant Consoles are specialized telephones used by operators or receptionists to handle a high volume of incoming calls. Their programming is more complex than a standard set and includes defining which call routing numbers they are responsible for answering. The console has many more keys and a more advanced display to allow the attendant to efficiently see incoming calls, see the status of internal lines, and transfer calls to their destinations. The 3605 Exam expects an awareness of these specialized applications.
A primary role of a support technician is to troubleshoot problems reported by users. The 3605 Exam tests your ability to use the system's tools to diagnose common station-related issues. For example, if a user reports that they cannot make outside calls, the first thing to check is their Class of Service (CLS) to see if they are restricted. If a feature is not working, you would check their key programming to ensure the feature is assigned correctly.
The command-line interface provides powerful tools for this. In LD 20, you can use the PRT command to print the detailed configuration of a user's TN. For more advanced issues, LD 32 provides a set of status and test commands. You can use STAT TN to check the real-time status of a telephone set, which will show if it is busy, idle, or in a locked-out state. This command is invaluable for determining if a phone is physically connected and communicating with the system correctly.
The Print (PRT) command in Load 20 is one of the most frequently used diagnostic tools for a CS1000 administrator. A solid understanding of its syntax and output is essential for the 3605 Exam. The PRT command allows you to display the detailed programming of a specific telephone by referencing its Terminal Number (TN). The basic command is simply PRT, followed by the TN prompt where you enter the Loop, Shelf, Card, and Unit of the phone you want to examine.
The system will then ask for a TYPE of print. You can print the TN block, which shows all the detailed programming data. You can also choose to print just the DN information, which shows how the keys are programmed. The output of this command is a structured list of all the prompts and their configured values for that telephone. This allows you to quickly verify a user's Class of Service, their feature key assignments, and all other aspects of their station's programming.
Call routing is the process that the Communication Server 1000 uses to determine the path that a call should take to reach its destination. A comprehensive understanding of the fundamental routing concepts is a major component of the 3605 Exam. The system's routing logic is based on a series of tables and lists that are checked in a specific order when a user dials a number. The primary goal is to match the dialed digits to a configured routing pattern and then select an appropriate trunk route to send the call out on.
The routing plan determines how calls are handled, whether they are internal calls between extensions, local external calls, long-distance calls, or international calls. A well-designed routing plan is essential for controlling costs, providing redundancy, and ensuring that calls are connected efficiently. The 3605 Exam will test your knowledge of the key building blocks of the routing plan and how they interact to make a successful call connection.
The foundation of the routing system is the dialing plan. The 3605 Exam requires you to understand how the system analyzes the digits a user dials. This is managed in the Coordinated Dialing Plan (CDP) tables. When a user dials a string of digits, the system compares it against the entries in these tables to determine the type of call it is. For example, it can identify a call as an internal extension call, a local call that requires an access code like '9', or a long-distance call.
A key part of the dialing plan is digit manipulation. Often, the digits a user dials are not the same digits that need to be sent to the public telephone network. The system may need to delete certain digits (like the access code '9') or insert other digits (like an area code for a local call). This manipulation is configured within the routing data blocks and ensures that the correct number format is sent to the trunking provider.
Once the system has analyzed the dialed digits and determined the destination, it must select a path to send the call. This is done using Routes and Route Lists, two fundamental concepts for the 3605 Exam. A Route, or Trunk Route, is a logical grouping of physical or virtual trunk members that all lead to the same destination, such as a specific telecom provider. The route contains parameters that define how the trunks within it will be used.
A Route List provides an additional layer of flexibility and redundancy. A Route List is an ordered list of one or more Routes. When a call needs to be sent, the system will try the first Route in the Route List. If all the trunks in that Route are busy or out of service, the system will automatically overflow to the next Route in the list. This allows for the creation of sophisticated routing schemes, such as a Least Cost Routing plan where the system first tries a low-cost VoIP route and then overflows to a more expensive traditional route if necessary.
Trunks are the physical or logical connections that carry calls between the CS1000 system and the outside world or another phone system. A deep understanding of trunking is a requirement for the 3605 Exam. Trunks are organized into groups, which are then assigned to a Route. Each individual connection within that group is called a trunk member. For traditional TDM (Time-Division Multiplexing) telephony, these members are physical channels on a T1 or E1 digital trunk card.
For Voice over IP, the trunks are logical connections, such as SIP Trunks. A SIP Trunk is a virtual connection to an Internet Telephony Service Provider (ITSP) that runs over the IP network. Each SIP trunk can handle multiple simultaneous calls, with the number of calls being determined by the available network bandwidth and the service provider's contract. The 3605 Exam will expect you to be able to differentiate between these different trunk types and understand their role in the routing plan.
While routing can be configured in Element Manager, the 3605 Exam requires knowledge of the traditional command-line interface for this task. The primary overlays for routing and trunking are LD 16 for Route data and LD 14 for Trunk data. To create a new route, you would access Load 16 (LD 16) and use the NEW command. The system will then prompt you for the key parameters of the route.
The most important prompts include the ROUT number, the ACOD (Access Code) that users will dial to access this route, and the TKTP (Trunk Type). You will also define parameters that control the signaling protocol and how the trunks in the route are selected. Understanding the key prompts and their functions is essential. The PRT command in LD 21 can be used to print and verify the entire routing plan, which is a common troubleshooting step.
For larger, multi-site environments, the CS1000 provides advanced routing capabilities to manage calls across a private network. A conceptual understanding of these is relevant for the 3605 Exam. Basic Alternate Routing (BARS) and Network Automatic Route Selection (NARS) are features that allow the system to make intelligent decisions about how to route calls based on cost and availability. BARS allows you to define different levels of calling privileges for different users, effectively restricting certain types of expensive calls.
NARS works in conjunction with the dialing plan to automatically select the most cost-effective route for a call. For example, if a user in New York dials a number in Los Angeles, NARS can be programmed to first try to send the call over a private IP trunk (a tie line) to the Los Angeles office for free. If that path is unavailable, it can then overflow to a public long-distance provider. This sophisticated logic is a key part of managing a large enterprise voice network.
In a Voice over IP network, it is critical to ensure that there is enough network bandwidth to support the voice calls without compromising call quality. Call Admission Control (CAC) is the mechanism that the CS1000 uses to manage this, and its purpose is a key topic for the 3605 Exam. CAC works by keeping track of the amount of bandwidth that is currently being used for voice calls between different network regions or zones.
Before a new IP-based call is allowed to connect, the system checks with the CAC logic to see if there is sufficient bandwidth available on the path that the call will take. If there is not enough bandwidth, the call can be blocked or, in some cases, re-routed over an alternate path, such as the public telephone network. This prevents the network from becoming oversubscribed, which would lead to poor audio quality, jitter, and dropped calls. It is an essential quality of service mechanism for any VoIP deployment.
Providing reliable access to emergency services is a critical and legally mandated function of any phone system. The 3605 Exam requires an understanding of how emergency calls (like 911) are handled. The system must be configured to recognize the emergency number when it is dialed and to route the call to the correct Public Safety Answering Point (PSAP).
A key part of this is providing accurate location information. For traditional digital phones, the location is known based on their physical wiring. For IP phones, which can be moved, the system uses a more dynamic method. It can map the IP address of the phone to a specific network zone or emergency response location. This information is then passed along with the call so that emergency responders know where to go. The routing for emergency calls must be designed to be the highest priority and the most resilient.
When users report problems making outbound calls, the issue often lies within the routing or trunking configuration. The 3605 Exam tests your ability to troubleshoot these common problems. The first step is to identify the scope of the problem. Is it affecting all users or just one? Is it affecting all types of calls or just calls to a specific destination? If a user cannot make any outside calls, you might check their Class of Service to see if they are restricted.
If a specific route is failing, the command-line tools are invaluable. In LD 32, you can use the STAT command to check the real-time status of a trunk route or even an individual trunk member. This will show you if the trunks are busy, idle, or in a maintenance (disabled) state. The TRAC command in LD 80 can be used to perform a live trace of a call as it is being set up, showing you exactly how the system is processing the dialed digits and which route it is selecting.
A fundamental part of the user experience in telephony is the various tones that provide feedback during a call. A basic understanding of these is relevant for the 3605 Exam. When a user lifts the handset, they expect to hear a dial tone, which indicates that the system is ready to accept digits. This tone is generated by a tone and conference resource within the CS1000.
After dialing, the user will hear other call progress tones. A ringing tone indicates that the call is being connected to the destination party. A busy tone indicates that the destination party is already on a call. A fast busy, or reorder tone, typically indicates that there is a problem with the network or that all the trunks are busy. As a technician, being able to recognize these different tones is a basic but important part of diagnosing call completion issues.
The Communication Server 1000 is a feature-rich platform, and a significant part of an administrator's job is to manage these features for users. The 3605 Exam requires a solid understanding of the most common telephony features and how to program them. Features like Call Forward All Calls (CFA) allow a user to redirect all their incoming calls to another number, such as their mobile phone. This is typically activated and deactivated by the user with a feature code, but its availability is controlled by the user's Class of Service.
Other common features include Call Hold, which allows a user to place a call on hold; Call Transfer, to move a call to another extension; and Three-Way Conferencing, to join three parties into a single conversation. Features like Ring Again, which automatically calls a busy extension back when it becomes free, and Call Pickup, which allows a user to answer a call that is ringing on a colleague's phone, are also essential to understand for the 3605 Exam.
Hunt Groups are a fundamental feature for distributing calls among a group of users, and their configuration is a key topic for the 3605 Exam. A hunt group is created by programming a primary directory number (the pilot DN) that users will call. You then assign a list of member DNs to this pilot number. When a call comes into the pilot DN, the system will "hunt" for an available member of the group to send the call to. The hunting sequence can be configured in different ways, such as top-down, circular, or simultaneous ringing.
Call Coverage is another critical feature for ensuring that calls are always answered. It provides a path of alternate destinations for a call if the original recipient does not answer. You can configure a call to ring at a user's desk for a certain number of rings, and if unanswered, it can then forward to another extension (like a colleague) or to a central voicemail system. The 3605 Exam will test your ability to configure these call flow features.
The CS1000 system integrates with a voicemail platform, historically CallPilot, to provide messaging services. A conceptual understanding of this integration is a requirement for the 3605 Exam. The integration is achieved through a set of dedicated voice channels that connect the CS1000 to the voicemail server. When a call needs to go to voicemail (e.g., because a user is busy or does not answer), the CS1000 routes the call over one of these channels to the voicemail system.
The communication between the two systems is managed by a special signaling protocol. This protocol allows the CS1000 to pass important information to the voicemail, such as the number of the person who was called and the number of the person who is calling. It also enables features like Message Waiting Indication (MWI), where the voicemail system tells the CS1000 to light the message lamp on a user's phone when they have a new message.
Proactive system maintenance involves regularly monitoring the system for alarms and errors. The ability to do this is a critical skill for the 3605 Exam. The CS1000 has a sophisticated alarming system that generates notifications for a wide range of issues, from a minor software warning to a critical hardware failure. These alarms are categorized by severity, with critical (CRIT), major (MAJ), and minor (MIN) alarms requiring different levels of urgency.
Alarms can be viewed in the Element Manager, which provides a graphical interface for alarm management. They can also be viewed and managed from the command-line interface, typically in LD 22. In addition to alarms, the system generates detailed system logs (SYS LOG) that record all significant events. A technician must know how to view these alarms and logs to diagnose problems and maintain the health of the system.
A regular and reliable backup of the system's configuration data is the most important maintenance task an administrator performs. The 3605 Exam places a strong emphasis on the backup procedure. The backup captures the entire Customer Data Block (CDB), which contains all the programming for users, routes, trunks, and features. Without a valid backup, recovering from a major system failure would be extremely difficult and time-consuming, requiring a complete rebuild of the database from scratch.
Backups can be scheduled to run automatically at regular intervals, typically during off-peak hours. The backup files are usually transferred to a remote server using a secure protocol like SFTP for off-site storage. An administrator must know how to configure the backup schedule, how to initiate a manual backup if needed, and, most importantly, how to verify that the backups are completing successfully. This is a non-negotiable part of responsible system administration.
In addition to backups, the CS1000 has a set of scheduled maintenance routines that run automatically to keep the system in good health. A high-level awareness of these routines is relevant for the 3605 Exam. These routines perform various housekeeping tasks, such as checking the integrity of the database, cleaning up temporary files, and auditing the system's configuration.
These jobs are typically scheduled to run overnight or on weekends to minimize their impact on system performance. An administrator can view the schedule of these maintenance routines and check the logs of their last execution to ensure they are running without errors. While these routines are largely automatic, a support professional should know what they are for and where to check their status as part of a regular system health check.
While the 3605 Exam is focused on operations and not deep implementation, a conceptual understanding of the upgrade process is expected. Upgrading a CS1000 system is a major undertaking that requires careful planning and execution. The process involves upgrading the software on both the Call Server and the Signaling Server. This might be a minor patch to fix a specific bug or a major release that introduces new features.
The upgrade process is typically performed during a maintenance window, as it requires the system to be taken out of service. It involves backing up the current system, installing the new software loads, and then carefully testing all functionality after the upgrade is complete. For hardware, an upgrade might involve replacing an older Call Processor card with a newer, more powerful one, or adding new line cards to increase the system's capacity.
Securing the telecommunications platform is a critical administrative responsibility. The 3605 Exam includes topics related to the basic security management of the CS1000 system. This involves managing the login accounts that are used to access the administrative interfaces, such as the Element Manager and the command-line interface. It is essential to enforce a strong password policy for these accounts and to ensure that each administrator has their own unique login.
Another important aspect of security is protecting the system from toll fraud. This is a type of attack where an unauthorized person gains access to the phone system and uses it to make a large number of expensive international or long-distance calls. This can be mitigated by applying restrictive Classes of Service to phones that do not need to make such calls (like lobby phones) and by carefully monitoring the call detail records for any suspicious calling patterns.
Call Detail Recording (CDR) is the feature that captures information about every call that is processed by the system. An understanding of its purpose and configuration is a topic on the 3605 Exam. For each call, the CDR output typically includes information such as the calling number, the called number, the start time and duration of the call, and the trunk route that was used. This data is invaluable for several purposes.
The primary use of CDR is for billing and cost allocation. Companies can use this data to charge back the cost of calls to different departments. It is also a critical tool for traffic analysis, allowing administrators to see when their peak calling times are and to ensure they have enough trunk capacity. Finally, as mentioned previously, the CDR data can be analyzed to detect potential toll fraud by identifying unusual calling patterns.
While previous sections discussed troubleshooting user and routing issues, the 3605 Exam also expects a basic understanding of how to approach system-level problems. If multiple users report issues, or if the system seems generally sluggish, the problem may lie with a core component. The first step is to check for any active system alarms in Element Manager or LD 22. An alarm will often point directly to the failing component, such as a faulty card or a software process that has stopped.
If there are no alarms, you would move on to checking the health and status of the core servers. This includes checking the CPU and memory utilization of the Call Server and the Signaling Server. In the command-line interface, LD 135 provides a set of powerful commands for checking the status of the software loads and system processes. A methodical approach, starting with alarms and moving to system status checks, is key to diagnosing these broader issues.
The final and most important step in your preparation for the 3605 Exam is to thoroughly review the official exam objectives provided by Avaya. This document is your definitive guide to the skills and knowledge that will be tested. It breaks down the exam into specific domains, such as System Architecture, Administration using Element Manager, Administration using the Command Line Interface, and System Maintenance. Each domain is further detailed with a list of specific tasks and concepts you are expected to know.
Use this official guide as a final checklist. Go through each objective and honestly evaluate your level of confidence. Are you comfortable building a phone using both the GUI and the CLI? Do you understand the components of the routing database? Can you identify the purpose of the key hardware cards? Any objective where you feel hesitant should be the focus of your last-minute review. Aligning your study with these objectives is the most direct way to ensure you are prepared for the 3605 Exam.
A recurring theme in the 3605 Exam is the duality of the administrative interfaces: the graphical Element Manager and the command-line overlay programming. A key skill is understanding the strengths of each and knowing which tool is appropriate for a given task. Element Manager is excellent for tasks that benefit from a visual layout, such as viewing the configuration of a phone's keys or managing a user's profile. It is generally more user-friendly for new administrators and for performing one-off changes.
The command-line interface (CLI), on the other hand, is often faster for experienced administrators who have memorized the commands. It is indispensable for tasks that are not available in the GUI, for advanced troubleshooting, and for creating scripts to perform bulk changes. The 3605 Exam will often present a scenario and ask you to choose the correct tool or to interpret the output from a CLI command, so proficiency in both is non-negotiable.
While you are not expected to memorize every single command, a deep familiarity with the most important command-line overlays is essential for passing the 3605 Exam. You should be able to navigate these key loads with confidence. LD 20 is the workhorse for station administration (Moves, Adds, and Changes). LD 16 and LD 14 are used for configuring Routes and Trunks, respectively. LD 21 is used for printing and verifying the routing data.
For system status and maintenance, several loads are critical. LD 22 is the primary tool for viewing and managing system alarms. LD 32 is used for checking the status of hardware, such as cards and trunks. LD 43 is used for backing up the system database. Finally, LD 80 provides powerful call tracing capabilities. Spend time in your final review practicing the most common commands (NEW, CHG, OUT, PRT, STAT) within these essential overlays.
If there is one single concept that you must understand inside and out for the 3605 Exam, it is the Terminal Number (TN). The TN is the thread that connects almost all aspects of the system's programming. It is the unique identifier for a physical or logical endpoint. The user's directory number is mapped to a TN. The features and classes of service are programmed on the TN. When you troubleshoot a hardware issue, you check the status of a TN.
Review the structure of the TN: Loop, Shelf, Card, Unit. Be able to look at a TN and understand its physical or logical place in the system's hierarchy. The exam questions will constantly reference TNs, either directly or indirectly. A complete and solid understanding of what the TN represents and how it is used as the primary key for all station-related data in the Customer Data Block is fundamental to your success on the 3605 Exam.
The 3605 Exam is focused on operations and maintenance, so troubleshooting skills are heavily tested. It is important to have a logical, step-by-step methodology for approaching problems. When a user reports an issue, the first step is always to gather information. What is the user's extension? What exactly is the problem? Can they reproduce it? Is anyone else having the same issue? This helps to define the scope of the problem.
Your next step should be to verify the user's programming. Use LD 20 to print their TN and check their Class of Service and key assignments. If the programming looks correct, you can then move on to checking the status of the relevant hardware or routes using the STAT command in LD 32. For complex call flow issues, a call trace in LD 80 is the final step. Having this structured approach will help you to logically work through the scenario-based troubleshooting questions on the 3605 Exam.
Many of the features on the CS1000 depend on other parts of the system's configuration. The 3605 Exam will test your understanding of these dependencies. For example, for Call Forwarding to an external number to work, the user must have the appropriate Class of Service (CLS) that allows it (CFXA). Additionally, the system's routing must be configured to allow calls to be forwarded out of a trunk.
Similarly, for voicemail integration to work, the system needs a correctly configured trunk route pointing to the voicemail system, and the user's station must be programmed with a voicemail DN and the correct Class of Service to allow message waiting indication. When you are studying features, do not just learn what the feature does. Also, think about what other system components are required to make that feature function correctly. This deeper level of understanding is what the 3605 Exam aims to validate.
When you are taking the 3605 Exam, read every question very carefully. The questions are often designed to be very precise. A single word can change the meaning of the question and point you to a different answer. Pay close attention to the details provided in any scenario-based questions. The exam is not trying to trick you, but it is testing your attention to detail, which is a critical skill for a telecom technician.
Use the process of elimination. For many multiple-choice questions, you will be able to immediately identify one or two options that are clearly incorrect. Eliminating these will significantly increase your chances of selecting the correct answer from the remaining options. If you are unsure about a question, make your best educated guess and flag it for review. You can come back to it at the end if you have time. It is better to answer every question than to leave some blank.
The preparation for the 3605 Exam is a journey that requires both theoretical knowledge and an understanding of practical, hands-on procedures. It is a comprehensive test of your ability to operate and maintain a complex and feature-rich communication system. By focusing your studies on the official objectives, mastering the key administrative interfaces, and developing a logical troubleshooting mindset, you can build the skills and confidence needed to succeed.
On the day of the exam, trust in your preparation. Stay calm, read each question methodically, and apply the knowledge you have worked hard to gain. Passing this exam is a testament to your expertise and dedication as a telecommunications professional. It proves that you have a deep understanding of the technologies that keep businesses communicating. Good luck with your final review and on your 3605 Exam.
