There are two Cisco 7200 routers that connected via DS3 interface ( M1T-T3 pa), we observed that the DS3 interface CRC, input error and carrier transitions
counters go up over time, and sometime cause the DS3 link goes down and back up in few minutes.
It appears to be the clock issue at DS3 interface , the router is current running IOS: c7200-is-mz.122-28a.bin
But there is no command: invert txclock under interface DS3. only invert data is available, any idea, do we need specific IOS feature code for the this command to tuning the clock setting.
Thanks fro your help in advance!!
