1. Also requires Program *60 to set TE or NT.
Step 3: Install the REBS
Note
1. Align the two connectors carefully while observing the "UP" arrows on the REBS.
2. Plug the REBS onto the RBSU.
Step 4: Install the RBSS
Note
1. Align the four connectors carefully while observing the "UP" arrows on the REBS.
2. Plug the RBSS onto the RBSU.
Step 5: Install the R40S
Note
1. Align the two connectors carefully while observing the "UP" arrows on the R40S.
2. Plug the R40S onto the RBSU.

The REBS provides a basic part of the RBSU/RBSS circuit functionality; therefore, it
must always be installed on the RBSU (see
If one or two additional BRI-NT circuits are required, install the RBSS (see
If ISDN PS-1 backup power for TE devices is required, install the R40S (optional PCB)
(see Figure 16-10).
