module, and module adapters and provides connections for signals and power. In addition to the
system components, the chassis has room for 12 additional common and channel modules. You can
also upgrade it in the field to a CrossConnect Server with the addition of one or two common modules
and module adapters.
1.4.3
Three Rack-Unit Chassis for CrossConnect Server
The DCS-9560 or DCS-9565 mainframe chassis is a three rack-unit, 19-inch wide by 5.25-inch high
equipment shelf. The chassis houses the power supplies, common modules, CrossConnect modules,
CrossConnect processor modules, and module adapters and provides connections for signals and
power. In addition to the system components, the chassis has room for up to 11 channel modules (10
in the DCS-9565).
1.4.4
Common Module — CM-5
The CM-5 common module provides multiplexing and de-multiplexing of a T1 port. A CrossConnect
Server with terminal multiplexer capability has one CM-5 module. A CrossConnect Server with drop
and insert multiplexer capability has two CM-5 modules. These products include the T1 Access Server
Installation and Operation Manual with shipment.
Its operation is essentially identical to that of the CM-5 module in the T1 Access Server multiplexers.
The T1 Access Server Installation and Operation Manual gives a complete description of the
functionality of this module, and the setup of the multiplexing section of the Access Server. Control
and signal connections to the CM-5 are made through an MA-216 module adapter on the rear panel.
1.4.5
CrossConnect Processor Module — CM-95
The CM-95 processor module controls digital cross-connect system (DCS) features such as control of
the T1 ports connected to the DCS-6 CrossConnect module as well as the CrossConnect mapping and
switching operations. Control and status connections for the CM-95 are made through the MA-251A
module adapter on the rear panel.
The CM-95 module controls all DCS functions. The module communicates with the DCS-6 module and
sets its operating parameters. DCS mapping is also handled by this processor. The processor
constantly polls the status of T1 links and makes routing decisions based on this status.
1.4.6
CrossConnect Module — DCS-6A
The DCS-6A module reroutes T1 traffic from one port to another and routes time slot traffic among
the circuits. It can handle traffic on as many as six T1 circuits. The time slot traffic is received, stored,
and retransmitted on the appropriate outgoing T1.
The DCS-6A module has no indicators or controls of its own. All user interfaces with this module is
controlled by the CM-95 processor board.
1.4.7
Channel Modules
The DCS-9560/9565 are compatible with all Intraplex T1 channel modules.
1.4.8
Module Adapters
Each common module and channel module in the system has its own module adapter, described in the
individual channel module manual sections.
In addition, there are three module adapters always present in the DCS-9560 and DCS-9565:
