Basic Rate Interface Board (BRIB)

This interface provides four Basic Rate Interface circuits. Each circuit is
comprised of two bearer (64Kbps each) and one data (16Kbps) channels
(2B+D). When a BRIB is programmed into the
interprets all B channels as trunks. Thus, one BRIB which contains four
2B+D circuits provides eight line appearances to the
maximum of eight BRIBs can be installed into the system (64 B channels).
The BRIB uses the U interface of the BRI standard. Connection to the
network is made via RJ45 connectors on the front edge of the board. No
NT1 device is required to connect to the central office. The BRIB card uses
eight time slots when installed.
When ordering BRI lines from the telephone company, specify
Capability P as the ordering code. National ISDN 1 (NI-1) is supported. No
other standards are supported.
Installation
1. Insert the BRIB and/or BRIB-E card(s) into the desired BKSU card

slot(s).
If installing a single BRIB, set switch 4 on SW2 to the ON position.
If multiple BRIB cards are being installed, set switch 4 on SW2 to
the ON position on the first card and switch 4 on SW2 on all other
cards to the OFF position. Switch 4 on SW2 determines if the
board is the Master Clock source for any digital trunk cards in the
system. Only one Master Source must be enabled in the system.
If installing a BRIB in a system that also has T1 or PRIB boards, use
either the T1 or PRIB card as the Master Clock and set all BRIB SW2
switch 4s to OFF.
