CHAPTER 2: Introduction

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.

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.
