The VCOM Module ordering options provide 4, 8, 16, 24, or 30 voice compression resources. • The VCOM Module provides automatic selection of CCITT Standard or ADTRAN-proprietary voice compression algorithms based on endpoint configuration. • The VCOM Module supports FAX at 14400 bps.
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. RELATED DOCUMENTATION The following document contains additional information about the ATLAS 550 frame relay feature: •...
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.
Chapter 2. Installation Instructions for Installing the VCOM Module Step 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 S indicator blinks red, yellow, and green for a time. The S TATUS TATUS indicator remains solid green when the VCOM Module is ready to use. At this time, you can invoke a system self-test;...

Operation Chapter 3 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.

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 menus and submenus, use the keyboard arrow keys to scroll to the ODULE appropriate row and column;...
Chapter 3. Operation Read Security: 5 TATE Denotes the module as O or O . Even though a module is physi- NLINE FFLINE cally installed, it must be marked O for it to be considered an available NLINE resource. Marking an installed module O may be useful during system trouble- FFLINE shooting.

ETCODER Some voice compression standards are proprietary and may be used only under specific licensing arrangements. The ATLAS 550 provides complete management of these licensed resources;...
Chapter 3. Operation Read Security: 5 RAME 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 end- point.) During a voice connection, the frame type displays as V...
VCOM Module. If a malfunction is suspected on the VCOM module, ADTRAN service personnel can use this menu to locate the prob- lem. This menu is documented here in the interest of completeness. The values automatically reset each time the VCOM Module is installed into the the ATLAS 550 chassis.
Chapter 3. Operation Read Security: 5 SAGE 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.
Chapter 3. Operation VCOM D 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 dis- carded during this operation.
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: and S ACTORY ESTORE YSTEM ACTORY The factory default settings for the VCOM Module can be restored from the terminal menus.
