Clocking with multiple connections.
I need some help on figuring out how I should setup clocking in the below scenario. In back of this router is UCM Business Edition.
Customer has 2851 with four vwic-mft-t1's (only three in use) and one NM-1CE1T1-PRI
0/0/0 - will have a PRI
0/0/1 - Crossover connection to NM-1CE1T1-PRI (use to get modem calls in from PRI over to NM-1CE1T1-PRI and onto onboard PVDM2-12DM modem module).
0/1/0 - T1 to Frame-relay carrier
1/0 (NM-1CE1T1-PRI) connects to 0/0/1 and sends modem calls to PVDM2-12DM
In a scenario like this where you have external connections to different services (PRI and Frame-relay) then you have another back to back configuration (modem work around) what is the optimum clocking setup?
Thanks in advance
