I have programmed forced relese tandem connection by timer. All works OK. But I have some question.

Description:

Incoming C.O. TR 10
Outgoing C.O. TR 11

For forced release it is enough to program

CM08>029:0
CM410>54:01
and at least one TR 10 or 11 in CM35119 set to 0

"CM35117 Forced release of tandem connection for incoming trunk."
For what does need CM35117 ?

CM35117 works completely similarly CM35119, that is
I program

35117>10:0
35117>11:1

35119>10:1
35119>11:1

forced relese works OK

and

35117>10:1
35117>11:0

35119>10:1
35119>11:1

forced relese works OK too :confused:

Further, how to work timer CM410>55 ?

I set 3505>10:0 but tandem connection doesn't drop.
