Study Group 13 has consented a new Recommendation that will give support for a widely deployed network technology in IP-based NGNs.

The Recommendation Y.1453 addresses required functions for network interworking between time division multiplexing (TDM) and IP networks.

TDM is a way to transmit multiple subscribers’ calls along the same transmission medium at the same time. Given that is a very widely used technology in existing telecommunications networks its continued support in NGN is imperative.

Y.1453 addresses "user plane internetworking mechanisms, connection multiplexing and procedures (for interworking)".
