Installing the IC-E1V interface card cables
The PRI is usually connected to a PBX or 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 31
for IC-E1V card port pin-out listing) with a PBX. A cross-over cable is required to connect to
an NT1, as illustrated in
figure 64
.

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.
