Summary

This Recommendation addresses required functions for network interworking between TDM networks up to DS3 or E3 rates and IP networks, in order to transport TDM traffic over IP networks. This Recommendation addresses user plane interworking mechanisms, connection multiplexing and procedures. These interworking mechanisms must ensure that TDM timing, signalling, voice quality, and alarm integrity be maintained. Details of the interworking model and required interworking functions are described. This Recommendation may not be suitable for use by Recognized Operating Agencies due to possible degradation of network synchronization performance as compared with native TDM transport.
