Primary Rate Interface Board
The Primary Rate Interface Board (PRIB) provides one Primary Rate Interface circuit. Each
circuit contains 23 bearer and one data channel (23B+D). When a PRIB card is programmed
into the
STSe system, the system interprets all B channels as trunks. Thus, one PRIB which
contains 23B+D circuits provides 23 line appearances to the STSe system. The PRIB card uses
24 time slots when installed. A feature of Flash 24 programming allows for partial signaling
over T1IBs or PRIBs. This allows you to limit the amount of time slots used per card to four, or
multiples of four up to 20.
The PRIB must be used in conjunction with a Channel Service Unit (CSU). Connection is made
via an RJ-45 from the PRIB to the CSU.
The PRIB accepts two DTRU4 boards.
Installation
1. Insert the PRIB card(s) into the desired card slot.
2. If installing a single PRIB, set SW2 to the ON position.
If multiple PRIBs are being installed, set SW2 to the ON position on the first card and SW2
on all other cards to the OFF position.
The PRIB comes with a clock cable. This cable is used when multiple PRIB and/or digital
trunk cards are to be installed in the system. The clock cable is supplied with each PRIB.
3. Connect the RJ-45 cable from the PRIB to the channel service unit (CSU).
4. Connect the network cable from the channel service unit to the Telco network.
5. Refer to ISDN and T1 Clocking (later in this section) for clarification on clocking and
cabling when combining PRIB and T1 cards in one Cabinet.
