 – a K5RCU or K5RCU2 must be installed in the Base KSU to interpret DTMF tones 
transmitted by devices connected to the standard telephone circuits.

 – an RRCS must be installed on the common control unit to interpret the DTMF 
signals for devices connected to the standard telephone circuits.

Loop Start CO Line Interface Unit (RCOU)
The RCOU in its basic configuration has four analog loop start CO line circuits, connecting to the 
public telephone network. 
Each RCOU line can be programmed for DTMF or Dial Pulse signaling and has a switch to control 
potential excess volume that can be created by a nearby PBX or CO. 
An optional RCOS subassembly can be attached to the RCOU for four more loop start lines. Each 
line can...

The RDTU is available for systems operating with a RCTUBA/BB, RCTUC/D or RCTUE/F 
common control unit. The RDTU normally requires the installation of a Channel Service Unit, 
which is not supplied by Toshiba. RDTU T1/DS-1 digital voice channels can be configured for SF 
or ESF format and either AMI or B8ZS line coding (see Table 23).
The new RDTU2, installed in a DK424 Release 4.0 system, supports the hook flash capability....

ISDN U-type Basic Rate Interface Unit (RBUU) (DK424 only)
The Basic Rate Interface Unit provides two Basic Rate Interface (BRI) “U” circuits. Each circuit 
provides two simultaneous voice and/or data connections with a single interface. BRI uses the 
2B+D transmission format which is defined as two 64-kbps bearer channels and one 16-kbps data 
(control) channel.

Option Interface Unit (PIOU)
The PIOU provides interfaces for Paging (Amplified, Unamplified, and Zone), SMDR, SMDI for 
Voice Mail integration, SMIS for ACD, DKAdmin Interface for on or off-site maintenance, an 
Alarm sensor, and a Remote Maintenance Modem subassembly (IMDU) that allows the system to 
be programmed from...

 – the PIOU provides two-relay contact pairs. One of the contact pairs can be set for 
control of a customer-provided door lock or control of a MOH source. The other relay pair can 
be configured to mute BGM while the page feature is being activated or for the Night Relay 
function.

Single Serial Interface Unit (RSSU)
The RSSU contains one RS-232 serial port for connecting an SMDI, SMIS processor, DKAdmin/
DKBackup PC or external modem. 
The RSSU provides a cost-effective alternative to the PIOU or PIOUS when only one other serial 
I/O port is needed, or when the other features of the PIOU or PIOUS are not required. The RSSU 
has a fixed speed of 1200 bps. It does not support SMDR, or the IMDU or RMDS...
