Telephony types tend to think more about service related information. With the increasing importance of ATM and mixed type data streams, this latter definition is becoming more important. Signalling, in cell and frame relay, fulfills a function (very roughly) analogous to selective routing in an internetwork. The authors have compiled a very complete overview, and set of tables, covering call control, link control, network and session conditions and other functions. For those approaching cell relay from the telephony side, there is mention, and brief description, of the underlying data communications concepts and protocols such as HDLC (High-level Data Link Control). copyright Robert M.
