Nortel Networks BCM200, 400 4.0 manual To connect the Gatm, Brim S/T RJ-45 wiring array

Chapter 9 Connecting the cables 143

Figure 77 shows the wiring pin-out for a BRIM S/T to the service provider. This diagram also applies to an S-Loop BRI and is capable of having S-Loop devices connected to it (video phones, terminal adapters, group 3 fax machines). The T setting on the BRI Loop is used when connected to the CO or PSTN.

Warning: The BRIM S/T 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.
