Try posting in the Disco section rather than an area section for better results.

Thanks for advice .

Hard reset
Check Most optic cables working

Each piece of kit has two leads going into them, one is the optics in other is optics out, so unplug both and see if one has a red light? if so just put/wiggle the ends together this bypasses the piece of kit for testing, ie the phone kit could go wrong and bring the entire Most loop down.
Sounds scary but it is not, I ran with two lead end taped together for a few days whilst waiting for new part to arrive.

Hard reset is always first port of call, free and easy, google it.

Thanks again for the detailed information we will use it to see if we can find the problem. We have tried the hard reset ?
