Loop won't come up

[Ski123]

I am having a problem with a loop that will not come up. It is on anolder 81C. I have tride replacing the QPC464 buffer card and also the QPC414 Network card. When doing a status in LD32 I get a CTYF:98 . The starnge thing is that loop 99 shares the QPC414 and I was aslo getting the CTYF:99 but was stil getting dial tone. After repacing the QPC414 I don;t get the CTYF anymore but still have no dial tone on Loop 98. Both the lights are lit on the QPC464.I also tried removing all the line cards and bringing the loop up. The loop does enable and disable when I issue the commands but still no dial tone on Loop 98 . Any suggestions?

You should also unseat all cards except for the buffer and try one card at a time. One shorted/bad line card could cause your problem.
