Multi page faxes are failing. cisco 2811 w/ fxs card

Users at a site were saying multi page faxes would come through. This was because of the slips on PRI. This is common if you are missing the network-clock-select T1 command on router.

1. Used sh controller T1 0/0/0 (pri interface) and looked for slips.
2. Cleared counters and did same command.
3. Used network-clock-select T1 0/0/0.
4. Check for slips again because they should stop now.
