MiCREW - Out Of Band System

The MiNDER Remote Control Unit (MiCrew) is a system for the management of Remote Sites over dedicated in-band and out-of-band data links. The whole system is scalable. In the simplest implementation, it may consist of a single Telnet terminal at the hub managing a single Remote Site over an Out-of-Band link, while more complex systems could incorporate a full management system at the Hub, automatically managing multiple Remote Sites.

Example - why used "When your remote satcom link has gone down - get it back up again without a physical visit"
