B.5 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
figure 12

Connecting an E1 PRI port to an NT1
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 pres-
ent 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 con-
nect the PRI cable to the PRI port only and not to any other
RJ-45 socket.
