MINI-LINK E and E Micro

can also command near-end and far-end loop-backs to be performed. Local

configuration of the capacity agile MMU at the near-end can be carried out

as well.

Local Management

The local supervision interface on the MMU enables fault finding and

measurement when a PC is not available.

Service Channel

The integrated maintenance system is optionally supplemented with two service

channels. These service channels may be configured as digital data channels

(64 kbit/s) or as omnibus voice channels with a built-in telephone interface.
