A multi-service integrated hardware circuit (20) transmits cells between an external interface (62) and plural on-board service devices (701, 702, 72, and 74) handling differing telecommunication services. The on-board service devices include one or more ATMF transceivers (701, 702), a Utopia 2 level device (74), and a circuit emulator (72) which interfaces with one of a PCM interface (301, 302) and an E1 or TI interface (32). The multi-service circuit comprises a multiplexer/demultiplexer core (60) which connects to the external interface (62) and which connects via an internal interface (64) to the plural service devices. In the illustrated embodiments, the external interface (62) and internal interface (64) are Utopia level 2 interfaces. |
