Title: Reduction of operator involvement in SVI/CNI calls
IPC: H04M3/487
Filed: 1980-04-22
Abstract: Currently on Service Interception (SVI) and changed Number Interception (CNI) calls, operators have to be involved in the interrogation of the calling party for the called number before routing the call to be subscriber on SVI or providing the changed number for the subscriber on CNI. In the processor system of System X it is possible to y arrange to have two memory banks, one for numbers on CNI and another for numbers on SVI. Also all the changed numbers can be stored in recorded announcement equipment. All calls routed to a number on CNI automatically are routed to the relevant part of the recorded announcement equipment, thus avoiding operator intervention. All calls to a sub on SVI are subjected to a called sub busy or free test. If the SVI sub is busy, busy tone is returned to the calling sub without operator intervention. Only if the SVI sub is free, is the SVI call routed to the SVI operator.
