GDK-100
DIGITAL KEY TELEPHONE SYSTEM

2.2.2.2
System Configuration Chart with Analog CO
a) Analog CO without WTIB
!
Note
1) If a customer uses 6 port extension boards, above configuration will be a little different shape.
2) Even though a customer uses 2B modules in GDK-100, the maximum capacity will be the same.
2B module can be connected to the every even-numbered port (0,2,4,…) of the boards like
DTIB12/DTIB24/DSIB, then any DKTU can not be connected to the consecutive port(1,3,5,…) in
this case.
