Abstract
An operator service terminal system connected to a telephone system switch retains the identifications of calling subscribers. Each operator terminal includes memory for storing at least one more subscriber identification than the number of loops served by that terminal. Once an operator services a call, it is not necessary to signal the telephone system switch to identify the caller if the identification is still in memory. In emergency situations, if a call is terminated before a caller can convey the location of the emergency, the calling party identification information can be used to call the caller back or can be relayed to emergency personnel for appropriate action.
