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 DB15 cable from the PRIB to the channel service unit (CSU).
4. Connect the network cable from the channel service unit to the network.
5. Refer to ISDN and T1 Clocking (later in this section) for clarification on clocking and
cabling when combining BRIB, PRIB, and T1 cards in one Cabinet.
Installing the DTRU4 Modules
1. Unpack the DTRU4 modules from their antistatic conductive bags.
2. Locate the CN1 and CN2 connectors on the DTRU4 modules.
3. Locate the CN16, CN17, CN18 and CN19 connectors on the PRIB.
4. Position one of the DTRU4 modules so that the CN2 and CN1 connectors align with the
CN17 and CN16 connectors on the PRIB respectively.
5. Push the DTRU4 module onto these connectors to seat it securely.
6. Position the second DTRU4 module so that the CN2 and CN1 connectors align with the
