ABSTRACT:
There is disclosed a circuit which can provide services of voice (referring to voice data) and data (referring to non-voice data) not only through the existing digital network but also through the integrated service digital network (ISDN), and separates voice, data and signaling information. The improvement includes: a serial/parallel conversion means which shifts and inputs in consecutive order the received data having serial basic access channel structure and outputs it in parallel; a first parallel/serial circuit which inputs in parallel only data from a certain designated output port of said serial/parallel conversion means and transmits it one bit by one bit in consecutive order and transmits it toward said data terminal; a second parallel/serial circuit which inputs a reversed RxSHEN signal and only voice from a certain designated output port of said serial/parallel conversion means by the second transmission clock which is applied from frequency divider and transmits them one bit by one bit in consecutive order toward a combo-codec; and a data collection means which inputs and collects only signaling information from the designated output port of said serial/parallel conversion means during a prescribed number of frame periods.
