Hi people, I have this problem:
DATE: 21MAR07 TIME: 15:05:56
CLASS: 2
274 DIGITAL TRUNK, CLOCK MALFUNCTION (SLIP)
DATE TIME ALP NOIF UNIT EQU BRDID
21MAR07 15:03:30 1 1 TLP30 006-1-10-00 27
INF1
129

274 DIGITAL TRUNK, CLOCK MALFUNCTION (SLIP)
DATE TIME ALP NOIF UNIT EQU BRDID
21MAR07 15:05:29 4 1 TLP30 006-2-00-00 27 INF1
130
what can I do? thanks!

Probably, it could be a problem with the synchronization with PSTN.
Look at "SCEXP;"
After a long time, it could that the board will be marked as "blocked

Ok thank, yes that was one problem, now I have other problem:

25 SLIP ON GROUP JUNCTOR LINE
DATE TIME ALP NOIF EQU INF1
28MAR07 10:20:31 9 1 001-0-**-** 1

Could be becouse the LIM 1 is to 6Km to the GS, the comunication is through Fiber Optic MonoMode and Umux Ascom 1300??

The transmission devices should derive timing for your PCM circuits from the port connected to the GS.

In other words, for the mux closest to the GS, the port connected to the GS should be the timing source, the port connected to the fiber should be slaved to the 1st port.

On the LIM side, the mux port connected to the fiber should be the timing source, and the port connected to the LIM should be slaved to the 1st port.

If you can't configure the timing for the Path in this manner, you will always experience frame slips on that circuit.

Good luck,

Dave Strang

Thanks!! I spoke with mux techical support and they must set the mux.

Thanks again!!.
