Black Box 5000 CommPak, Expansion Modules, MS1 Voice/Fax Card, MS1 56K CSU/DSU Module MT150C

2.3 The CommPak

The Multiserver 5000 Commpak plug-in software cartridge contains all of the Multiserver 5000’s operating software. To add features and program upgrades is simple—just change the cartridge.

NOTE: The Multiserver 5000 CommPak cartridge is required for the unit to operate.

2.4 Expansion Modules

Plug in up to three of these data expansion modules to suit your data networking needs; use any combination. Add the five data channels on the CCM, and the Multiserver 5000 can support up to 41 data channels (ten of which may be synchronous).

MX215C—6-channel sync/async data expansion module with EIA RS-232C connectors.

MX222C—6-channel async-only data expansion module with EIA RS-232C connectors.

MX223C—12-channel async data expansion module with RJ1D connectors. These connectors are DB25- compatible when used with the correct adapter cables.

MX224C—12-channel async data expansion module with RJ1D connectors and integral line drivers; compatible with EIA RS-422 and RS-423 standards.

NOTE: The expansion modules can only go in slots B, C, and D on the Multiserver.

2.5 MS1 Voice/Fax Card

The Multiserver 5000 can support up to eight voice/fax channels with single- or dual-channel voice/fax expansion modules. Once these modules are installed, they can be fully configured from the same command facility used to control the data channels. The network manager has a single point of control for the entire network.

CHAPTER 2: Introduction

NOTE: To get eight voice/fax channels, use four dual-channel cards (MX225C-2). The cards will occupy all of the rear-panel slots available for expansion modules (except for the NMS module, which fits underneath the CCM).

The voice/fax modules support all telephone interface types, including E&M Type 1–5 for PBX operation, KTS for key telephone systems and handsets, and OPX for off-premise exchange operation. The module generates ring and dial-tone when required. There is no need to install external signal converters.

These modules integrate voice, fax and data signals, automatically switching the integrated software for fax demodulation when it detects a fax signal and resuming speech (voice) compression when it identifies a voice signal.

2.6 MS1 56K CSU/DSU Module (MT150C)

Use the integral CSU/DSU module to interface the Multiserver 5000 to a 56-Kbps digital line. The Automatic Line Buildout (ALBO) feature makes installation very simple: the CSU/DSU can automatically adjust signal output according to line distance (that is, the distance between the CSU/DSU and the first repeater in the DDS line to which it is attached). You won’t have to worry about cable-length equalization problems during installation.

2.7 MS RLB Module (MX229A)

The MS RLB Module is a Remote Ethernet LAN Bridge. Once the RLB is installed, LAN bridge traffic is integrated with voice and data traffic over your leased line.

The RLB is a standard MAC-layer bridge and is compatible with any ethernet protocol. The RLB supports 802.1D Spanning Tree protocol to prevent network loops. Bridge management can be done through the Multiserver’s Command Facility.
