Refer to the Strata DK40 Programming Manual or DK Library CD-Rom for more details.
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 3-28).
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
3-28).
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 3-28).
1. Align the two connectors carefully while observing the “UP” arrows on the R40S.
2. Plug the R40S onto the RBSU.
