Nortel Networks BCM1000 manual BRI RJ45 wiring array, Pin #/connection System side

Chapter 10 Wiring the modules 135

•Figure 56 shows the wiring pin-out for a BRI to the service provider (BRI loop set to T)

Warning: The BRI must only be connected to an NT1 provided by the service provider. The NT1 must provide a Telecommunication Network Voltage (TNV) to Safety Extra Low Voltage (SELV) barrier.

This diagram also applies to an S-Loop BRI, allowing connection to such S-Loop devices as video phones, terminal adapters, and Grp 3 Fax machines. Note: the S-loop does not supply supplementary power, such as required by video devices. Supplementary power must be supplied by a separate power supply.
