Abstract
The series connected interceptor is a control system for assisting in providing improved service operations for a PBX system. This control system is connected in series in a DID trunk between a TELCO central office and a PBX. By the nature of where it is connected and its function, the control system enables a telephone answering service to sense when an incoming DID call has rung on an extension for a predefined number of rings and to answer such call with the identity of the extension being called. The control system also can provide incoming DID call screening or call forwarding.
