CHAPTER 5 Cabling the Device
➢
To connect the device to the LAN:
1. Connect one end of a straight-through RJ-45 Cat 5e or Cat 6 cable to the LAN port, located on
the rear panel and labeled GE LAN.
2. Connect the other end of the cable to a network device or entity.
3. For 1+1 LAN protection, repeat steps 1 and 2 for the standby port, but connect it to another
network (but in the same subnet).
Ethernet port interface cabling must be routed only indoors and must not exit the
building.

ISDN BRI Interfaces

This section describes how to connect the device to ISDN BRI lines.

Connecting BRI Lines

The BRI ports can be connected to ISDN terminal equipment such as ISDN telephones or PBXs.
Each BRI port can be configured either as termination equipment/user side (TE) or network
termination / network side (NT). Up to eight terminal equipment (TE) devices can be connected per
BRI S/T port, using an ISDN S-bus providing eight ISDN ports. When configured as NT, the BRI
port drives a nominal voltage of 38V with limited current supply of up to 100 mA.
To protect against electrical shock and fire, use a 26 AWG min wire to connect the BRI
ports to the PSTN.
