CHAPTER 2: Introduction

three (3) high-speed interconnect links (a
Multiserver-to-Multiserver connection) in ports A1
to A3, five (5) mux links (a Multiserver-to-feeder-
mux 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.
