inverse multiplexing

Advantages of using inverse multiplexing over separate links include:

A simple analogy to transport can help explain the distinction between multiplexing and inverse multiplexing.

This is inverse multiplexing.

A LAG (Link Aggregation Group) is a method of inverse multiplexing over multiple Ethernet links, thereby increasing bandwidth and providing redundancy.

This inverse multiplexing option was briefly popular with some high-end users before ISDN, DSL and other technologies became available.

Virtual concatenation (VCAT) is an inverse multiplexing technique creating a large capacity payload container distributed over multiple smaller capacity TDM signals.

By inverse multiplexing, these are first demultiplexed into parallel streams, and each one mapped to a (possibly complex) symbol stream using some modulation constellation (QAM, PSK, etc.).

Inverse Multiplexing for ATM (IMA) is another aggregation protocol, which unlike PAF uses fixed size cells, sending them across multiple links in a Round-Robin fashion.

Inverse multiplexing (IMUX) has the opposite aim as multiplexing, namely to break one data stream into several streams, transfer them simultaneously over several communication channels, and recreate the original data stream.

Inverse Multiplexing for ATM (IMA) is a standardized technology used to transport ATM traffic over a bundle of T1 or E1 lines, which is called an IMA Group.

The other product, Channel Striping or inverse multiplexing, is a software feature now available with Ultra's standard Block Multiplexer Channel network adaptors, which enables users to access and transfer mainframe data over multiple input-output channels in parallel to a TCP/IP network.
