The DK40i, DK424 and DK424i Release 4.3 system supports the RBUU/RBUS interface unit
(
) according to the common control units resident in the system. (Table
14-8). The DK40i R2 supports TBUU in the Base Cabinet.
LEDs on the RBUU/RBUS show a continuous status of operation. Refer to
for a list
of each LED’s status.
shows the location of the LEDs and connectors.
RBUU and TBUU Installation
Important!
The DK40i, Release 1 does not support the RBUU or TBUU interface.
Before installing an RBUU or TBUU PCB into a DK system, a number of system programs must
be run. Be sure to run Program *60 to identify all station (LT) and CO (NT) BRI circuits. Program
*60 causes port and line numbers to shift. We recommend running these programs in the order
listed before installation. This allows the RBUU to function immediately upon insertion beginning
with a self-check loop-back test and then normal operation. Before you can begin installation of
the RBUU, you may have to install the subassemblies.
The TBUU PCB is shown in
➤
To install the subassemblies (RBUS)
➤
Place the RBUS card (component side facing down) onto the RBUU connectors. Apply firm,
even pressure to ensure proper seating of the connectors. The RBUS card should have been
installed at the factory.

To install an RBUU PCB
1. Insert the RBUU (component side facing right) into the appropriate expansion unit slot and
apply firm, even pressure to ensure proper seating of connectors.
2. After installing the RBUU, gently pull the PCB outward. If the connectors are properly seated,
a slight resistance is felt.

To install a TBUU PCB
1. Insert the TBUU (component side facing right) into the DK40i Base Unit and apply firm, even
pressure to ensure proper seating of connectors.
2. After installing the RBUU, gently pull the PCB outward. If the connectors are properly seated,
a slight resistance is felt.
