The network port interface is an RJ48C jack located on the rear panel.
You must use either GDC cable P/N 022H024-XXX (RJ48C plug-to-
plug) or 022H021-XXX (RJ48C plug-to-terminal lugs) to connect the
T1 line to the DSU. The plug-to-plug cable is labeled NETWORK and
CSU to indicate where each end is used.
Pinouts for the network end of the network interface cables are listed
below:
For Canadian installations only, a special cable is required
for the network connection. Use GDC cable P/N 022H020
(RJ48C to DB15F) to connect the network port to the T1
line.
