Abstract
Concurrent calls are multiplexed over packet network connections such as TCP/UDP/IP connections. Initially, semi-permanent, open channels (e.g., TCP and/or UDP channels) are established between two or more packet switches. The switches format incoming calls, as necessary, and multiplex them onto the open channels. Identifiers may be added to the multiplexed calls to facilitate the demultiplexing of the calls by the receiving switch. The multiplexed calls are encapsulated into packet network protocol packets (e.g., TCP/IP or UDP/IP) for routing over a packet-based network (e.g., IP).
