::: Bad Clocks :::

Answered Question
Jun 18th, 2008

Hello,

when I restart the physical connection I receive the following error:

%TRUNK_CLOCK-6-BAD_CLOCKS: There are no good clocks in the system. Remain in HOLDOVER mode

And I am not able to establish Layer 1.

The clock missing can cause this issue?

With best regards and thanks.

I have this problem too.

Try configuring framing no-crc4 under controller.

Seems to me your circuit is down. If you do "show controllers T1" you will likely see "loss of singal" or other major error.

Urban_Nights Wed, 06/18/2008 - 05:20

Yes is true :)

in my case is E1.

I can see Receiver has loss of frame..so, this means that I have a problem in the remote link side?

E1 6/4 is down.

Applique type is Channelized E1 - balanced

Receiver has loss of frame.

Now I will try to connect MGC via IUA/SCTP.

Thank you and regards.
