Summary

Many cable television operators are upgrading their facilities to provide two-way capability and using this capability to provide high-speed IP data services per ITU-T Recs J.83 and J.112. These operators now want to expand the capability of this delivery platform to include a variety of time‑critical services. This Recommendation is one of a series of Recommendations required to achieve this goal. It provides a network-based call signalling protocol necessary to establish connections.

This revised Recommendation comprises updates of all the relevant developments since the Recommendation was originally approved (March 2001) and includes modifications made in J.162 Amendment 1 (February 2002).
