Flexible Slot Assignment
The flexible slot architecture on DK424 systems enables almost any combination of CO line and
station ports. Slots in the KSU can be assigned as station, CO line, or Option Interface slots in a
variety of custom configurations. All stations, CO lines, and optional printed circuit boards are the
same size and use the same connector to mount into the backplane of the base or expansion Key
Service Unit cabinet.
Any printed circuit board can be installed in any slot, with the exceptions of the RCTU common
control unit, which goes in designated processor slots, and the PDKU or PEKU which must be
installed in slot 11 if RSIU is not used. If RSIU is used, RSIU must be installed in slot 11, in this
case a PDKU or PEKU must be installed in slot 12 of the DK424 to enable system programming
and system administration functions.
Benefits
Increases the variety of line/station combinations, so a customer can have a system that is sized
and tailored to meet their specific needs.
