Rbsu/Rbss Installation; Programming Overview - Toshiba Strata DK40 Installation & Maintenance Manual

DK40 Universal Slot PCBs
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
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.

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.

Programming Overview

Program 03: Assign the RBSU PCB slot position (15 ~ 18), as type 78
Program *09: Assigns incoming digits to ring system groups (DDI Mode Only)
Program *10: Assigns incoming digits to ring ACD groups (DDI Mode Only)
Program *11: Assigns translation of Called Party Number (CPN) on incoming calls
Program 14-0: Assigns incoming ringing to ACD group (DEL mode only)
Program 16: Assigns the ISDN2 channels to line groups
