NOTE:
The preferred network interface is the RJ48X. If a customer's site
uses the RJ48X interface and the customer's equipment does not
provide connection, the T1 trunk's receive pair is looped back to the
transmit pair. This simplifies troubleshooting the T1 trunk from the
central office.
In most installations, the network interface is connected through a
cross-connect field to the control unit. However, for systems with
fewer than 24 extensions, you can connect the trunk wires directly
to the control unit.
When constructing wiring fields between the network interface and the
control unit, you must order hardware as individual parts. Do not use
Interconnect Wiring or Systimax wiring kits.
