power to TE devices on the RBSU/RBSS transmit and receive wire pairs as shown in
Figure 3-25. This power arrangement is also known as phantom power.
Each of the four circuits on RBSU/RBSS can be connected to share the R40S using option
switches on the PCBs as shown Table 3-14. Before using the R40S as a backup power source,
you must make sure that the TE devices do not require more power than the R40S can supply
and the TE is compatible with the ISDN PS-1 power arrangement. Figure 3-25 shows the
power limits of the R40S.

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. For further
information refer to the Strata DK40 Programming Manual.
