E1 Port

The E1 Port 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 T1/E1 Port with a PBX. A cross-over cable is required to connect to an NT device, as illustrated in figure 14 on page 45.

Hazardous network voltages are present in the T1/E1 cables. If you detach the cable, detach the end away from the IpLink or interface card first to avoid pos-

sible electric shock. Network hazardous voltages may be present on the device WARNING in the area of the T1/E1 port, regardless of when power is turned OFF.

To prevent damage to the system, make certain you connect the T1/E1 cable to the T1/E1 port only and not to any other RJ-45 socket.
