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 an NT device, as illustrated in
page 43.

Hazardous network voltages are present in the PRI cables. If
you detach the cable, detach the end away from the Smart-
Node 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.
