Multiple Piou, Pious, Rssu Installation - Toshiba STRATA DK14 Installation And Maintenance Manual

Multiple PIOU, PIOUS, RSSU Installation

Up to three PIOU, PIOUS, or RSSU PCBs can be installed in a system to simultaneously provide:
maintenance terminal (or modem) interface, Management Information System (MIS) for ACD
interface, and RS-232 voice mail interface (Toshiba proprietary or SMDI).
Each of these interfaces are provided by the modular jacks on a separate PIOU, PIOUS, RSSU
(Figure 12-36). Interface assignments are made in Program 03 (Code 41, 42, and 43). PIOU and
PIOUS Paging, SMDR, relay control, alarm sensor, and door lock functions will be active only on
the PIOU or PIOUS PCB which is assigned the lowest Program 03 code (41, 42, or 43). RSSU
only provides the TTY interface for SMDI, local maintenance, or ACD MIS but not for SMDR,
built-in maintenance modem or system OA.
If TSIU or RSIU/RSIS is installed, functions enabled in Program 76 will operate as programmed
and the same functions programmed in Program 03 (Code 41, 42, and 43) will not operate. For
more details regarding RSIU/RSIS/RMDS and TSIU installation, see RSIU installation in
