Attaching Digital
Network Cables
This section describes the network interfaces and provides
procedures and illustrations for connecting to each network. Refer
to the procedure for the network you are using with the
Concorde¥4500. You may also refer to the
Concorde¥4500 Servicing
Guide
for information on pin assignments.
Internal Four-Wire Channel Service Unit (CSU)
The Concorde¥4500 supports an internal CSU daughter board for
connecting to a CSDC 56-kilobit network or to a four-wire DDS line.
The internal CSU interface also provides an RS-449 connector to
support the concurrent connection of the system to both a switched
and a dedicated network.
The wires in the four-wire switched interface are used as follows:
two wires transmit data, and two wires receive data.
You must follow these guidelines when providing the cable:
❑
Bring the four unused conductors out to the connector.
❑
Use an RJ-48S jack at the termination point of the extended
demarc.
