inverse multiplexer

An inverse multiplexer splits a high-speed channel into several independent channels with lower transmission speeds or assembles a broadband channel from several independent data streams.

In inverse multiplexing, the subscriber has one channel at his disposal, which is formed from several individual channels that can also be switched via different paths in the network. The bandwidth of the transmission channel is determined by switching between two communicating inverse multiplexers. This is a demand-based determination in the form of bandwidth on demand or multirate circuit switching( MRCS).

The Bandwidth on Demand Interoperability Group has specified a transmission protocol with multiple modes for inverse multiplexing. In the bonding protocol, transmission between two inverse multiplexers can be with or without any control: With or without synchronization, error correction, or delay compensation. If an error occurs, the connection is terminated.

Such a configuration can be used, for example, to transmit high-speed services such as videoconferencing over several B-channels connected in parallel with multirate ISDN or LAN-LAN connections.
