Step 3:
Install the REBS
Note
The REBS provides a basic part of the RBSU/RBSS circuit functionality; therefore, it must
always be installed on the RBSU (see
Figure 5-11
).
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
If one or two additional BRI-NT circuits are required, install the RBSS (see
Figure 5-11
).
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
If ISDN PS-1 backup power for TE devices is required, install the R40S (optional PCB) (see
Figure 5-11
).
1. Align the two connectors carefully while observing the “UP” arrows on the R40S.
2. Plug the R40S onto the RBSU.
