inverse multiplexor

In communications, a device that breaks up a high-speed transmission into several low-speed transmissions, and vice versa. It is used to transmit LAN and videoconferencing traffic over lower-speed digital channels. For example, to transmit Ethernet over a T3 link, the 10 Mbps Ethernet channel would be inverse multiplexed into multiple 64 Kbps channels of the T3 line. A 336 Kbps videoconferencing transmission could be split into six 56 Kbps channels to transmit over a Switched 56 service. Contrast with multiplexor.

At the heart of the system is the iMux, a newly developed IP-to-ASI gateway, which performs synchronization, conversion and multiplexing of IP streams received by the Gigabit Ethernet interface into MPEG streams transmitted over DVB-ASI interfaces.
Furthermore, for environments where a DSLAM-based DSL bonding solution is preferred, Netopia also offers SDSL and IDSL routers and DSUs that support Copper Mountain Networks' IMUX technology.
The reps are currently being trained on both the existing line of CSU/DSU products and the newly announced IMUX 2000 family.
