13 CO LINE/DIGITAL TELEPHONE
INTERFACE UNIT (KCDU)
13.00 General
13.01
The KCDU, which can only be installed in the
Expansion Unit of DK16 (it will not function in DK24/
56/96), has two loop start CO line circuits and four
digital telephone circuits. The KCDU digital tele-
phone circuits can support all but one of the de-
vices supported by either the PDKU or Base Unit
integrated digital telephone circuits: digital tele-
phones, PDIU-Dls/PDIU-Dl2s, PDIU-DSs, ADMs,
and a DDCB. The KCDU does not support a DDSS
console. One or two KCDU PCBs may be installed
in the Expansion Unit. No other station or CO line
PCB can be installed if the KCDU is installed.
13.02 The KCDU is shown is Figure 5-21, and its
controls, connectors, and indicators are described
in Table 5-H.
