3 PRIs with Slip Secs & Errored Secs

Unanswered Question

User Badges:

I have a new telephony system that was implemented yesterday with Cisco Call Managers / Unity / Contact Center, etc.

We also have xMedius Faxing Solution as well. 

In a nutshell, our overall calls appear to be working fine.  However, our xMedius faxes work 90% of the time but other times it comes in half page missing.
I believe I can relate this to the slips / errors on the 3 PRIs. 


My config on the PRIs as the Carrier is Master:  I'm not as familiar with the clocking, etc.....

network-clock-select 1 T1 0/0/0  *** Do I need this ? ***

Greg,


Usually FAX issues like you described are caused by clock slips


You config looks good to me.


YES - YOU DO NEED THE COMMAND YOU HIGHLIGHTED


Veify if you are seeing the clocks


show network


This should display where to clock is being sourced


show controller T1 0/0/0


This should display the counters including any clock slipped errors

With my 3 PRIs, it appears I got rid of the slips / errors on my first 2 PRIs. 

However, I still get errors o nthe thrid PRI (0/1/0). Doest this look correct?

network-clock-select 1 T1 0/0/0 *** Do I need this for every PRI ? ***

network-clock-select 2 T1 0/0/1 *** Do I need this for every PRI ? ***

network-clock-select 3 T1 0/1/0 *** Do I need this for every PRI ? ***


Here is the sh network clock

Network Clock Configuration
  ---------------------------
  Priority      Clock Source    Clock State     Clock Type

     1               T1 0/0/0        GOOD            T1
     2               T1 0/0/1        GOOD            T1
     3               T1 0/1/0        GOOD            T1
    11               Backplane       GOOD            PLL

  Current Primary Clock Source
  ---------------------------
  Priority      Clock Source    Clock State     Clock Type

     1          T1 0/0/0        GOOD            T1


Thanks for the input.

Greg,


Yes - this looks good and well done for adding

network-clock-select 2 T1 0/0/1

network-clock-select 3 T1 0/1/0


Now your router should be using the Priority 1 clock from T1 0/0/0

If that link fails the clock moves on to Priority 2 T1 0/0/1 etc


I assume that all 3 PRIs are from the same provider.

If you are seeing slips on 0/1/0, I reckon the issue is with the T1 line from the SP.


All 3 lines should be in sync.
