Paradyne COMSPHERE 3000 - Manual (Page 16)

Introduction
1-3 3000-A2-GA31-80 December 1994
Network Interface Modules (NIMs) can be installed at
the rear of the carrier (when not occupied by an Auxiliary
Backplane) to provide the PSTN (dial) or switched
56 kbps digital service interface for both DSUs and
dial/lease modems. There are nine different NIMs. For a
list of the feature/part numbers of these NIMs, see
Appendix B of this manual.
Alternatively, you can install up to two Auxiliary
Backplanes at the rear of the carrier to allow Model 3151
T1 CSUs and Model 3161 T1 DSU/CSUs to provide an
interface between a T1 digital network and Customer
Premise Equipment (CPE).
A modular DSU or dial/lease modem is a circuit card
that contains “gold finger” contacts on the rear edge of the
card and is supplied with a rear connector plate. A rear
connector plate has two DTE connectors, a 25-pin
EIA-232 connector and a 25-pin CCITT V.35 connector.
It allows removal of a modular circuit card without
disconnecting the DTE cables at the rear of the carrier.
Also, there are connector modules which have six ports
and are supplied with the modular DSU-TDM or
DSU-MCMP circuit cards. These connector plates and
modules function as interfaces between the modular
circuit cards and the DTEs.
This manual describes the procedure for installing a
COMSPHERE 3000 Series Carrier into a COMSPHERE
72-inch cabinet. A COMSPHERE 72-inch cabinet with
available equipment-mounting dimensions of 63 inches
high by 19 inches wide has the capacity to hold up to six
carriers, allowing for a high-density installation
combination of up to 96 DSUs and/or dial/lease modems.
COMSPHERE 3000 Series Carriers can also be mounted
in other types of EIA standard 19- or 23-inch wide
cabinets. (The heights of the other types of cabinets may
vary.)
