1. Not all maximum capacities may be achieved simultaneously.
2. DECT terminals can be registered and used up to 20 stations. But GDK-20W system supports the only four(4)
simultaneous calls basically because the MBU has one wireless terminal interface circuit.
When WTIB card is installed to SLOT5, the number of simultaneous calls is increased up to the twelve(12)(One
base station provides the four(4) simultaneous calls.).
The WTIB has the two(2) wireless terminal interface ports.
3. One RS-232C port can be installed in the position of the MFB. The purpose of RS-232C port can be
programmable in Admin station programming.
It is recommended that the RS-232C serial cable whose length is below 10 meters is used.
