Abstract
In an information transmission system for use for inter-node trunks, both circuit-switched and packet-switched traffic is handled, the former being given priority. The system uses successive equal-length envelopes each providing a number of bits usable to provide a number of frames each usable for either sort of traffic. Circuit-switched traffic has priority and uses frames at the beginnings of the envelopes, after which packets are handled. The envelope is of such a size that it provides frames for all circuit-switched channels to be catered for, and in most cases the remainder of the envelope can handle packet traffic.
