Abstract
An interface arrangement provides interworking between packet (IP), time division multiplex (TDM) and asynchronous (ATM) networks, and incorporates a TDM framer providing an interface to the TDM network, a packet framer providing an interface to the packet network, and ATM adaptation function providing an interface to the ATM network. The ATM adaptation function comprises a set or suite of integrated circuit devices, the devices being partitioned by AAL functions into a first device set arranged to perform a common part sublayer function and a second device set arranged to perform service specific sublayer functions. The composition and nature of the device sets can be chosen to match the traffic types and quality of service requirements.
