CCIS BASIC PROGRAMMING
When the offices are connected with No. 7 CCIS, and if all outgoing trunks of the incoming office are busy,
or all outgoing trunks are in the make busy condition in the incoming office, or the no answer timer of
outgoing call (T1 timer) time-out occurs, the incoming office can send the busy/fault occurrence message
to the outgoing office. The outgoing office where the message is received can detour the call via an another
trunk route such as ISDN.
To provide this detouring feature for the systems, do the following programming to the incoming office.
In outgoing office, program the data for providing the Alternative Routing in advance.
