DK424 Installation

RCTUA, RCTUBA/BB, RCTUC/D, RCTUE/F Common Control Units

Hardware Options
Some PCBs must be configured for hardware options prior to installation of the PCB in the
cabinet. Configuration instructions for internal hardware options are provided in the individual
PCB installation procedures in this chapter. Configuration instructions for external hardware
options are provided in Chapter 12 – 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 Strata DK Programming Manual for
detailed programming instructions.

Common Control Units
System:
Current Version:
Older Version(s):
The common control unit provides centralized control for the system. It incorporates a 16 or 32 bit,
68000-type microprocessor and contains a custom time switch and conference Large Scale
Integration (LSI) circuitry.
The processor operating software is programmed on four read-only-memory (ROM) chips on the
RCTUA3 or RCTUA4, BB3 or BB4, and D3 or D4 PCBs and on the Flash Memory PCB RMMS
on the RCTUF3 or F4 PCBs. The operating software (ROM or RMMS) is factory-installed.
The RCTU PCBs also provide busy tone detection as a standard feature for Auto Busy Redial
(ABR) and interfaces with optional RRCS DTMF receivers, feature keys (RKYS1, 2, or 3) for
Auto Attendant (AA), Automatic Call Distribution (ACD), Management Information System
(MIS) for ACD, Toshiba proprietary RS-232 and SMDI voice mail interfaces.
ACD and attendant consoles requires the RCTUBA/BB, RCTUC/D and RCTUE/F processors.
Important!

PCB Installation Power Supply Considerations

1. The power supply must be Off whenever removing or installing the common control unit—
RCTUA, RCTUBA/BB, RCTUC/D and RCTUE/F (see
2. It is recommended that the power supply be Off, whenever possible, when removing or
installing the other PCBs.

RCTUA1, RCTUB1&2, RCTUC/D1&2, RCTUBB3, RCTUD3, RCTUF3
When installing RCTUE/F, you must remove the Motherboard Jumper Unit (MBJU)
from the DK424 Base Cabinet (between R11 and RCTU slot on the front side of the
cabinet motherboard), see
BB, C/D, the MBJU must be installed on the DK424 Base Unit.
