Installing the IC-E1V interface card cables
The PRI is usually connected to a PBX or telco switch (local exchange (LE)). Type and pin-outs of these
devices vary depending on the manufacturer. In most cases, a straight-through RJ-45 to RJ-45 can be used to
connect the PRI (see
table 34 for IC-E1V card port pin-out listing) with a PBX (an NT). (See figure 64 ). A
cross-over cable is required to connect to an LE, as illustrated in figure 65 .
Note
Pins not listed are not used.
The Interconnecting cables shall be acceptable for external use and shall be
rated for the proper application with respect to voltage, current, anticipated
temperature, flammability, and mechanical serviceability

Hazardous network voltages are present in the PRI cables. If you detach the
cable, detach the end away from the SmartNode or interface card first to avoid
possible electric shock. Network hazardous voltages may be present on the
device in the area of the PRI port, regardless of when power is turned OFF.
To prevent damage to the system, make certain you connect the
PRI cable to the PRI port only and not to any other RJ-45 socket.
