- Abstract
- We have proposed the structure of an interworking system and the method of inter processor communication for providing existing narrowband network interworking in ATM switching system. The proposed interworking module consists of 8 low speed application specific units (LASU), 3 high speed application specific units (HASU) and a interworking control processor (IWP). The LASU and the HASU are application specific and the IWP is application independent. From the interworking point of view, application specific means non-ATM function such as DS1/E1/DS3 frame relay service and circuit emulation service and application independent means common ATM function. The inter processor communication function is to transfer call control messages, OAM messages, TDM channel establishment messages between the main processor and interworking processor.
