RBSU/RBSS Installation
Step 1:
Run Related Programs
➤
Run all ISDN programs related to RBSU/RBSS BRI circuits prior to installation of the PCBs. This
enables the circuits to operate immediately upon insertion. ISDN BRI programs are explained in
the
Strata CTX Programming Manual
under the ISDN tab.
Step 2:
Set Option Switches/Jumpers
➤
Set all option switches and jumpers on the RBSU and RBSS PCBs before plugging the RBSS onto
the RBSU or inserting the RBSU into the system. RBSU/RBSS switch/jumper information and
locations are shown in
