Black Box 5000 manual Feeder Muxes, Module

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.

CHAPTER 2: Introduction

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.
