Base Unit Interfaces/PCBs
Base Unit (4 CO lines, 8 digital ports): X built-in
KSTU (4 standard ports): _____ one max.
Expansion Unit Station and line PCBs
KCDU (2 CO lines and
4 digital ports):
_____ two max. (KCDU cannot be installed
with any other type of
- or - station PCB or PCOU PCB)
PDKU (8 digital ports): _____ one max.
- or -
PEKU (8 electronic ports): _____ one max.
- or -
PSTU (8 standard ports): _____ one max.
- or -
PESU (2 standard ports and
(4 electronic ports):
_____ one max.
PCOU (4 CO lines): _____ one max. (PCOU can be installed with
PDKU, PEKU, PESU, or
PSTU, but not with KCDU)
NOTES:
1. The Base Unit by can only support up to 12 stations (8 digital and 4 standard)
and four CO lines.
2. The Expansion Unit can support up to eight stations and four CO lines.
3. If installing two DDCBs, a PDKU or a KCDU is required to support the second
DDCB—no matter what the total number of digital ports.
4. If installing two DDSS Consoles, a PDKU is required to support the second
DDSS Console—no matter the total number of digital ports. (KCDU does not
support DDSS.)
3. Refer to Worksheet 3 to determine option and peripheral requirements.
4. Refer to Worksheet 4 to determine the amount of power used by the system.
