Chapter 10 - Triad 1/2 System Configuration
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
contains four 2B+D circuits provides eight line appearances to the
maximum of five BRIBs can be installed into the system (40 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 requires 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.
Analog Station Boards
Electronic Key Telephone Interface Board (ETIB)
The ETIB provides the interface to 12 electronic telephones or DSS/BLF stations.
The ETIB board has one red LED indicator for line status. The LED lights red when the
circuit is busy and not light when idle.
The station connections are via one 50-pin female champ (amphenol type) connector
located on the front edge of the card.
The card ejector tabs are color coded green.

system, the system interprets all B channels as trunks. Thus, one BRIB which
Vodavi has successfully integrated its BRI ISDN with the Lucent 5 ESS Central Office.
Vodavi ISDN should work with all Central Office switches, but this has not been
verified. Therefore, some delays in service may be experienced.
