I have a question regarding proper network clock configuration on a 2851 with a 4-port HWIC and a 2-port VWIC2-2MFT-T1/E1. There are 3 T1's (WIC 0 - 0/0/0, 0/0/1, and 0/0/2) and 2 PRI's (WIC 2 - 0/2/0 and 0/2/1).
The T1's are all taking slip secs errors at an increasing rate. The network clocking is currently configured with:
network-clock-participate wic 0
network-clock-participate wic 2
network-clock-select 1 T1 0/2/0
From this, I would infer that the T1's on WIC 0 are getting their clock information from the PRI on WIC 2 (0/2/0). All controller interfaces are set to 'line' which I have confirmed is correct.
Would it be best to remove the 'network-clock-participate wic 0' or add 'network-clock-select 2 T1 0/0/1'?
When I issue the show network-clocks command, I see no reference to a clock source for any WIC 0 interface(s).
Perhaps some insight in to T1/PRI best practices would help me understand and possibly answer this question myself.
Any and all help is MUCH appreciated!
