can be disabled through system programming. If disabled, DISA is released when the CO-to-CO line
connection is made.

CO-to-CO Line Call Duration Limitation
For a call between two outside parties, even if end of call detection cannot be performed, the call can be
disconnected by a system timer (→ 4.1.17 CO Line Call Limitation). If the timer expires, the line will be
disconnected unless the originating caller extends the time by sending any DTMF signaling. The caller
can prolong the call duration within the preprogrammed time period and preprogrammed number of times.
