Common Control Units (Rctua, Rctub, Rctubnbb, Rctuc/D) - Toshiba Strata DK 280 Installation Manual

for external hardware options are provided in Chapter
6-Peripheral Installation.
Software Options
PCBs are configured for software options through
programming, following the installation instructions of
the PCBs. A programming overview for each PCB is
provided in the individual PCB installation procedures
in this chapter. Refer to the Programming Part for
detailed programming instructions.
Installation
4.2.3 PCB
Considerations
Whenever removing or installing PCBs, observe the
following requirements:
1. The power supply must be OFF whenever
removing or installing the common control unit-
RCTUA, RCTUB, RCTUBNBB, and RCTUC/D.
2. It is recommended that the power supply be OFF,
whenever possible, when removing or installing
the other PCBs.
4.3 Common Control Units (RCTUA,
RCTUB, RCTUBA/BB, RCTUC/D)
The common control unit provides centralized control
for the system. It incorporates a 68000-type
microprocessor and contains a custom time switch
and Conference Large Scale Integration
The unit also provides busy tone detection as a
standard feature for Auto Busy Redial (ABR) and
interfaces with optional RRCS DTMF receivers,
feature keys (RKYSI, 2,
(AA), Automatic Call Distribution (ACD), Management
Information System (MIS) for
proprietary RS-232 and SMDl voice mail interfaces,
and system Open Architecture interface (OA). ACD
and attendant console requires the Release 2 or 3 (4-
ROM) version of
OA requires DK280 Release 3 processors and an
system operates with one of the following six common
control units:
The RCTUAI (Release 1) or RCTUA3 (Release 3)
The R C T U B I PCB (Release l ) , RCTUB2
(Release 2) or RCTUBNBB (Release 3).
