Router clocking (slips/errors)

I understood from a Cisco SE that 2nd generation MFT (VWIC2-2MFT-T1/E1 vs VWIC-2MFT-T1) has dual PLLs, so that data port 0/1/0 could have a separate clock source then the voice on port 0/1/1.

Now a TAC SE says you have to have a separate network module to get separate timing with a second generation MFT.

Problem: Central Office is delivering two T1s, one voice, one data with different clocking proven via T-BERD. Show controller t1 has slips/errors.

What can I do to resolve this? If I put in a WIC-1DSU-T1 alongside the 2MFT would it fix the timing problem/slips/errors?

Re: Router clocking (slips/errors)

Try with the the network-clock-select command.
