Network and Communications Security

A common method of providing fault tolerance with leased lines is to bundle several T1s using an inverse multiplexer located:

  • A at one end of the connection.
  • B at both ends of the connection.
  • C somewhere between both end points.
  • D in the middle of the connection.
Explanation

An inverse multiplexer splits traffic across the bundled T1 links at one endpoint, while a corresponding device at the remote endpoint recombines the traffic into the original stream. Cisco documentation states that the connected remote end must also operate in IMA mode and that the cells are recombined at the other end of the connection.
