Chapter 1 Introduction VOICE COMPRESSION MODULE OVERVIEW The Voice Compression Module (VCOM Module) combines with other ATLAS 550 components to implement a voice over frame relay (VoFR) capability in the ATLAS 550 series of Integrated Access Systems. You can order the VCOM Module with support for 4, 8, 16, 24, or 30 simultaneously compressed calls. FUNCTIONAL DESCRIPTION The VCOM Module installs onto any option module that can be installed in the ATLAS 550 chassis.
Chapter 1. Introduction PHYSICAL DESCRIPTION The VCOM Module provides no external interfaces. Other ATLAS 550 components provide both the network and customer interfaces. An internal bus exchanges information between the ATLAS 550 chassis and the VCOM Module.
Chapter 2 Installation UNPACK AND INSPECT Carefully inspect the VCOM Module for shipping damages. If you suspect damage, file a claim immediately with the carrier and then contact ADTRAN Technical Support. If possible, keep the original shipping container for returning the VCOM Module for repair or for verification of shipping damage. CONTENTS OF ADTRAN SHIPMENT The ADTRAN shipment includes the following items: • VCOM Module • VCOM Module User Manual (Insert into main ATLAS 550 User Manual.
Chapter 2. Installation Instructions for Installing the VCOM Module Step 1 Action On the rear of the ATLAS 550 chassis, remove the cover plate covering the slot into which the option module carrying the VCOM resource module is to be inserted. If theATLAS 550 option module is already in the ATLAS 550 chassis, simply loosen the thumbscrews at both edges of the option module faceplate and slide the module out of the chassis.
Chapter 2. Installation POWER-UP AND INITIALIZATION After installing the VCOM Module into the ATLAS 550 chassis, the front panel STATUS indicator blinks red, yellow, and green for a time. The STATUS indicator remains solid green when the VCOM Module is ready to use. At this time, you can invoke a system self-test; refer to the ATLAS 550 User Manual for details. This self-test sequence may take up to eleven (11) minutes.

Chapter 3 Operation OVERVIEW You can configure, control, diagnose, and view the status of the VCOM Module with the terminal menus. This chapter describes the menu items available for operating the VCOM Module using the terminal menu. Security Passwords You must have the appropriate password level to use the terminal menu to edit items. (See the section Access Passwords in the ATLAS 550 User Manual for detailed information on working with passwords.

Chapter 3. Operation MENU ACCESS The ATLAS 550 system controller automatically detects the presence of the VCOM Module as it is installed into the system. To access the VCOM MODULE menus and submenus, use the keyboard arrow keys to scroll to the appropriate row and column; then, press Enter on the keyboard. Refer to the ATLAS 550 User Manual for detailed instructions on navigating through the terminal menus. MODULES The following paragraphs describe the MODULES menus of the ATLAS 550.
Chapter 3. Operation STATE Read Security: 5 Denotes the module as ONLINE or OFFLINE. Even though a module is physically installed, it must be marked ONLINE for it to be considered an available resource. Marking an installed module OFFLINE may be useful during system troubleshooting. If you choose OFFLINE, the module will not be in an alarm condition, but will display OFFLINE. Only if STATE reads ONLINE can the ATLAS use an installed module for any data movement.
Chapter 3. Operation VCOM MENUS Figure 3-3 shows the MENUS for the VCOM Module. The following sections describe these options. Figure 3-3. VCOM Menus INFO Read Security: 5 Displays module and software information for the VCOM module. PART NUMBER Read Security: 5 Displays the ADTRAN part number for the module (read-only). SERIAL NUMBER Read Security: 5 Displays the VCOM Module's serial number. ASSEMBLY REVISION Read Security: 5 Displays the assembly revision level for the VCOM Module (read-only).
Chapter 3. Operation AVAILABLE This resource is available for use as a voice compression resource. BUSY This resource is currently being used as a voice compression resource. TESTING This resource is currently being tested and is not available for use. FAILED This resource has failed testing and is not available for use. ALGORITHM Read Security: 5 Denotes the voice compression algorithm being used by the VoFR device. Any VoFR device can use any available compression algorithm.
Chapter 3. Operation FRAME TYPE Read Security: 5 Displays the kind of frame the ATLAS 550 receives from the frame relay endpoint connected to the VCOM channel, allowing users to monitor the kind of data being carried on the network and processed by the ATLAS 550. (The ATLAS 550 interprets the most-recently received frame from the endpoint.) During a voice connection, the frame type displays as VOICE. For a FAX connection, a variety of frame types display.
Chapter 3. Operation CONFIG Provides diagnostic tools for suspected problems; under normal operation, users do not configure the VoFR devices. DEVICE Read Security: 5 Identifies the VoFR device on the VCOM Module. VoFR devices are numbered 1 through 32. STATE Write Security: 3; Read Security: 5 Controls the configuration state of the individual VoFR device. The VCOM Module determines the initial configuration state of each device.
Chapter 3. Operation USAGE TIME Read Security: 5 Measures the total elapsed time that a VoFR device has the status BUSY. The time is expressed with millisecond precision. Available VoFR devices are assigned new connections using a round-robin technique where all other available VoFR devices must be used before a given device is assigned a new connection. This scheme tends to use allVoFR devices evenly.
Chapter 3. Operation VCOM DROP Read Security: 5 Counter-measures each frame dropped or discarded by VCOM Module during communication with the ATLAS 550 system controller about a VoFR device. The exchange protocol is designed so that no frames should be discarded during this operation. A consistent pattern of dropped frames by a given VoFR device may indicate a faulty VoFR device or an overloaded ATLAS 550 system.
Chapter 3. Operation ATLAS FEATURES USED WITH VCOM MODULES In addition to the VCOM menu items, the ATLAS 550 system provides additional services that operate in conjunction with the VCOM Module: FACTORY RESTORE and SYSTEM SELF-TEST. FACTORY RESTORE The factory default settings for the VCOM Module can be restored from the terminal menus.
