Interfaces and Cables
This appendix contains technical information on interfaces and cables.
Network Interface (NI)
The NI (Network Interface) RJ48C 8 position modular connector is
wired so that a straight-through RJ48C cable may be used to connect
the T-1 CSU/DSU to the RJ48C wall jack supplied by the T-1 carrier
provider. A straight-through cable Part Number CB8S0002 or
CB8S0003 is provided with the unit. This cable is specially designed
using twisted pair wires and any replacement of this cable by the
customer must use twisted pair. The interface pins on the rear of the T-
1 CSU/DSU NI connector is as follows:
