BRIM wiring chart

The digital BRI ISDN lines connects to the BRIM through the RJ-45 jacks on the front of the

media bay module (MBM). See the figure BRIM RJ-45 ports on page 223. You can connect up to

four BRI ISDN lines to the BRIM.

The figure BRIM RJ-45 ports on page 223, the table BRIM RJ-45 port wiring on page 223, and the

table BRIM line numbering on page 224 apply to S-Loop and T-Loop connections. S-Loops

connect S-Loop devices such as video phones, terminal adapters, and Grp 3 Fax machines. The

T-Loops connect to the CO/PSTN.

Figure 93 BRIM RJ-45 ports

The table BRIM RJ-45 port wiring on page 223 and the table BRIM line numbering on page 224

list the wiring details for the RJ-45 ports.

Warning: For a U-loop connection, you must connect the BRIM only to an NT1 supplied

by the service provider. The NT1 must provide a Telecommunication Network Voltage

(TNV) to Safety Extra Low Voltage (SELV) barrier.
