    The VCOM Module ordering options provide 8, 16, 24, or 32 voice com- pression 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.

  • Page 12: Physical Description

    Chapter 1. Introduction PHYSICAL DESCRIPTION The VCOM Module provides no external interfaces. Other ATLAS compo- nents provide both the network and customer interfaces. An internal bus exchanges information between the ATLAS chassis and the VCOM Module. See Figure 1-1 for an illustration of the VCOM Module. Figure 1-1.

  • Page 13: Chapter 2 Installation

    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.

    Operation Chapter 3 OVERVIEW You can configure or control the VCOM Module from any of several PLUS sources (see Table 3-1). The ATLAS 800 User Manual provides detailed instructions on operating each supported source. The remainder of this chapter describes the menu items available for operating the VCOM Module using the terminal menu.

    Chapter 3. Operation MODULES MENU DESCRIPTIONS > Read Security: 5 (Slot) Displays the number of available slots in the ATLAS chassis. Slot 0 refers to the ATLAS Base Unit. TYPE > Write Security: 3; Read Security: 5 Displays the module type currently installed in the slot or the module type you plan to install in the slot.

  • Page 19: State

    Chapter 3. Operation STATE > Read Security: 5 Denotes the module as Online or Offline . Even though a module is physi- cally installed, it must be marked Online for it to be considered an available resource. Marking an installed module Offline may be useful during system trouble- shooting.

    Chapter 3. Operation » Serial Number Read Security: 5 Displays the VCOM Module's serial number. ATLAS records the serial number along with any manual changes to the module's configuration (read-only). If a failed module is replaced with a different VCOM Module, ATLAS detects this module and resets the old configuration data.

    G.723.1 CCITT G.723.1 compression; 6.3 kbps bandwidth. Netcoder ADTRAN-proprietary NETCODER compression; 6.4 kbps bandwidth. Some voice compression standards are proprietary and may be used only under specific licensing arrangements. ATLAS provides complete management of these licensed resources; therefore, users are not required to take additional steps to ensure conformance with licensing provisions.

  • Page 23: Connection

    Chapter 3. Operation points can be configured so that no silence frames are transmitted during periods of relative silence. For compatibility with these devices, the VCOM Module can be configured to expect that silence suppression is Enabled ; thus, no frame relay traffic is generated during periods of silence. Both voice endpoints must agree on the silence suppression setting.

  • Page 26: Atlas Drop

    Chapter 3. Operation » ATLAS Drop Read Security: 5 (ATLAS Frames Dropped) Counter-measures each frame that is dropped or discarded during communication between the ATLAS and the VoFR device. The exchange protocol is designed so that no frames should be discarded during this operation.

    Chapter 3. Operation ATLAS FEATURES USED WITH VCOM MODULES PLUS In addition to the VCOM menu items, the ATLAS 800 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.
