Remote Network Interface
Return to Task List
The Remote Network Interface (formerly Initialization and Administration System (INADS) provides a
9600 bps modem connection for the remote management terminal. The network interface trunk should
appear on the twenty-fifth pair of a RJ21X network interface jack. The trunk is a two-way, rotary dial,
loop start trunk that connects to a maintenance circuit pack, the processor circuit pack, or the SYSAM
circuit pack through the Remote Network Interface terminals at the trunk/auxiliary field.
Figure 201,
Connections at Trunk/Auxiliary Field,
on page 524 shows a typical Remote Network Interface trunk
installation.
