I am consistantly getting the subjected error messages ('No Clock Source' and 'D channel cannot be established') on one particular RMX I have.
I have two PRI's (E1's) between a Mitel PBX and this RMX and it constantly causes me issues with the PRI basically becoming unusable, dropping existing audio conferences and not allowing new participants to join.
A reboot of the RMX resolves this problem, but it always occurs again a week or two later.
I was wondering whether anyone else is having this issue consistantly happen and, if so, whether they were able to rectify the problem?
Any help much appreciated.

Appreciate your quick reply.
I had reviewed the threads you conducted a search on, but they didn't really provide an answer to my sepcific problem.
I do have 2 spans, so have a backup clock source, so the normal System Flag won't help me. At the same time as the clock source losing sync, I lose the D channel, rendering the PRI useless.

In the meantime, I would be very interested to hear from other forum members as to their experences with this, if any.
