E1 PRI

The E1 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 with a PBX. A cross-over cable is required to connect to a NT1, as illustrated in

E1 PRI

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.
