2851 GW, 4 slots are ok to insert VWIC2-2MFT-T1/E1. My question is about the clock.

1. If I have two T1s in the one slot connecting to same PBX, how should I configure the clock on this two T1s?

2. If I have one more T1 in the 2nd slot which alos connects to the same PBX, how should I program the 3rd one's clock?

Btw, PBX gets clock from PSTN and distribute clock to GW.

I tried different combinations but there alwasy slips in either 1 or 2 T1s.

When you configure network clock use, you select which modules participate and what the source of the network clock will be.To configure the clock source of a DS1 link, use the clock source command in interface configuration or ATM interface configuration mode. To restore the default line setting, use the no form of this command.< clock source {line | internal | loop-timed}
