[csshin]

Anyone know the below logs?

PRN: Lock To Internal Clock, TDM_CLK_SOURCE = 0x80
-----------
PRN: LockToFalc 5, TDM_CLOCK_SOURCE 0x00

We have trunk line with E1-R2.
Afer display the upper logs, Ipoffice do not receive call from external.

TSP engineer said that we sent the signal to IPO but doesn't answer from IPO.

If you know, explain for the logs, pelease.

Lock to Falc means t1 timing. try changfing to CSU mode if not already. Also try CRC checking to see if the phone company is not providing CRC. I had to have the phone company run a tberd test and rerun the line on a similar issue

I just ran into this running 2 IPO's connected via PRI (not SCN) on 3.1.65. The IPO was losing timing w/ the provider and locking to its internal clock (BTW - this would cause all of the digital phones to reset).
