separate pieces of equipment to transmit these four different types of signals.
The base unit (MX219A) comes with the Communications Control Module (CCM), universal power supply, an AC power cord, and this manual.
The CCM has six ports. You can configure up to
Figure 2-1. The Multiserver acts as your communication hub.
Different types of data are integrated and then transmitted over one link.

three (3) high-speed interconnect links (a Multiserver-to-Multiserver connection) in ports A1 to A3, five (5) mux links (a Multiserver-to-feeder­mux connection) in ports A1 to A5, or five (5) data input/output channels in ports A2 to A6.
The high-speed interconnect or composite channels and the mux channels support RS-232C, V.24, and V.28 interfaces. Data-transmission speeds can be from 1200 bps to 72 Kbps on interconnect links or up to 19.2 Kbps on mux links. Operation is serial synchronous, full-duplex, with internal or external clocking.
The five I/O ports on the CCM present themselves as DCE. They can be set up for either synchro-nous or asynchronous data transmission.
In addition to the CCM, there are expansion and access modules, detailed below, that let you customize your network to your specific data communication needs.
2.2 Feeder Muxes
The Multiserver 5000 can support up to five (5) feeder muxes. Each feeder mux can support both async data channels and voice/fax channels. The following multiplexors are link-compatible with a Multiserver:
• Communication Box II (MX003A) with one of the following CommPak Multiplexor Cartridges:
— Enhanced Statistical Multiplexor
(MX100A)
— Quick Stat CommPak Mux
(MX107A-R2)
• Statplex Multiplexor 4- and 8-port models (MX611A and MX622A)
Figure 2-2. The back panel of a fully outfitted Multiserver 5000 is shown here. With the six-channel
sync/async expansion module in expansion slot B and the twelve-channel expansion module in expansion slot C, this Multiserver 5000 could have up to 23 data channels. Ten of these data channels could be synchronous. Expansion slot D has a two-channel voice/fax module, allowing for all voice, fax, and data information to be sent over one leased line. The leased line is connected to the Multiserver 5000 through the CSU/DSU module in expansion slot E.

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 DB25­compatible 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.

24
2.8 MS1 NMS Module (MX227C)
The MS1 NMS Module (network management system module) fits underneath the CCM on the rear panel of the Multiserver 5000. It features a command port to hook up a PC or terminal, a printer log port to connect a serial printer, and an alarm relay. You can run diagnostic tests and generate statistics reports, and then print the results (logs) on your own connected printer.
2.9 MS1 V.35 Converter/DCE (MX226)
The MS1 V.35 Converter/DCE plugs into an interconnect- or mux-link port on the CCM (locations A1 to A5). Then you can interface the port with a DCE that operates according to the V.35 recommendation.
NOTE: Use of this converter module requires a
separate DCE interface cable, which is included.
2.10 MS1 X.21 (V.11) Converter (MX228)
The MS1 X.21 (V.11) Converter plugs into a mux­link port on the CCM (locations A1 to A5). Then you can interface the port with a DCE that operates according to the X.21 (V.11) recommendation.
NOTE: Use of this converter module requires a
separate DTE or DCE interface cable. Order cable number EVNX21-003M-MF.
2.11 MS1 Rackmount Kit (RM220)
The RM220 rackmount kit lets you mount the Multiserver 5000 in your present 19-inch rack system.

3.1 Initial Considerations
The Multiserver 5000 offers the ability to connect one of the following units and their associated links:
• Multiserver (1000 or 5000) via an Interconnect Link.
• Feeder Mux (Communication Box II or Statplex Multiplexor) via a Mux Link or an X.21 Link
The interconnect link can be connected using the integral MS1 56K CSU/DSU module. Any of the links can be connected using an external ISU or modem. If the external devices are not RS-232, the appropriate converters are required.
The Multiserver 5000 supports four types of network topologies:
• Point-to-point
• String
• Star
• Distributed Star
Utilizing these topologies, the Multiserver 5000 can serve as either a terminated node (traffic is terminated in, or attached to the local node) or a
switching hub (no local attached devices). Without local traffic (data/voice/LAN), the Multiserver’s link capacity increases.
There are three elements to be considered when putting together a Multiserver 5000 network:
• Channel Performance
Burst 288 Kbps
• Link Capacity
Terminated 72 Kbps
Switched 192 Kbps
• Delay (varies Do not exceed six link
between channel hops in any network type and protocol) path (6 node hops)
Important
You cannot have a closed loop in a Multiserver network.
When designing a Multiserver network, it helps to keep in mind the different capabilities of the Multiserver 1000 and Multiserver 5000. A summary of these are detailed in Table 3-1.

3.4 Syntax for Node Numbers and IDs
Multiserver units and compatible multiplexors share the same syntax for the node numbers and IDs.
Node # Syntax: Use 1 through 254. (Number 1 is input as 1, not 001.)
Node ID Syntax: One to eight uppercase or lowercase characters. Any combination of alphanumeric characters and underscore ( _ ) is allowed. No spaces are permitted. Node IDs are not case-sensitive. They should be as short as possible.
Using the syntax described and a sample worksheet copied from Appendix A, plan the node numbers and node IDs that will be used in your network. Make sure that you plan the port and channel assignments, etc., for your network before reading the rest of this manual. Worksheets for the channels are also in Appendix A.
3.5 Default Node Numbers and Node IDs
The units are shipped with default configurations. These default settings are listed in Table 3-2. (See Appendix C for a complete listing of all Multiserver 5000 default settings.)
Figures 3-1, 3-2, and 3-3 are typical Multiserver networks and give the default settings of each node.
If the optional NMS module is installed, the default
3.2 Worksheets for the Network
Appendix A contains worksheets you can use to plan your network. Make photocopies of the worksheets you will need and then complete them. You will need to refer back to your worksheets for other aspects of the configuration process later in this manual.
3.3 Nodes and Hubs
Each Multiserver and compatible multiplexor in a network is referred to as a node. Each node must have its own node number and node ID. These are used by the Multiserver system to identify each node in the network.
NOTE: There must be no duplicate nodes in the
network!
All nodes connected locally are considered a local hub group. This includes the Multiserver 5000 and any feeder muxes connected directly to it.
All nodes on the other side of an interconnect link are considered a remote hub group. There may be feeder muxes connected directly to the remote Multiserver. They are considered part of the remote hub group.
