ABSTRACT:
The present invention is directed to an adaptor for simulating the presence of a PBX device in a telephone network. The adaptor connects to an external line from the central office, and a test set. When the central office seizes the line, the adaptor responds by inducing a wink. The central office, believing that it has received an authentic PBX response, sends data to the PBX site responsive to the wink. The adaptor relays these signals to the external test set for analysis.
