Primary Rate Interface Board (PRIB)

The PRIB board allows the network connection to a Primary Rate ISDN
interface. It provides one Primary Rate Interface circuit. Each circuit is
comprised of 23 bearer channels and one data channel (23B+D). The
system interprets all B channels as trunks/line appearances. A maximum
of six PRIBs can be installed into the system. The PRIB uses 24 time slots.
The PRIB contains an ISDN interface circuit, control circuitry, and
synchronous clock control circuits. DTMF tone detection units can be
installed optionally on the PRIB. The PRIB accepts two DTMF-A boards.
The PRIB has 8 LEDs on the front edge of the PCB which indicates errors
of ISDN line, in-use status, and synchronous clock enable status.

The PLLU must be installed on the MPB for the PRIB card to operate
properly.
Vodavi has successfully integrated its PRI ISDN with the Lucent 5 ESS,
Siemens, Stromburg Carlson, and the DMS100 Central Offices. Vodavi
ISDN should work with all Central Office switches, but this has not been
verified. Therefore, some delays in service may be experienced.
