Figure 78 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.

3 Insert the connector into the jack on the MBM.
Refer to the BCM 4.0 Administration Guide for steps about changing the default settings for
each line or loop.
4 You can now use Element Manager to configure the lines or sets associated with the MBM
(see the BCM 4.0 Administration Guide).
To connect the GATM, G4x16, or G8x16
1 On the front of the MBM, locate the amphenol connector.
2 Wire one end of the cable to the demarcation blocks of the building.
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.
Note: For G4x16 and G8x16, the lower 25-pair connector is the analog trunk part of the
module and is wired the same as the GATM.
