Have a BCM 400 with analog trunks with no dial tone at phone have proved into the card that there is d/t coming from provider made sure the line was still programmed on the set line numbers are 121 129, 130 , changed out the card still no dial tone ,checked the dips on old to new card ,programmed lines on another set ,same issue " help "

What Software version?
The GATM - for this module, what bus and offset are you using?

And which pairs on the Amphenol Cable are you using?

will find out s/w version using white blue pair ,the system has been working for two years , have it on a battery backup also so no power loss when you go on the line there is no dial tone but after 6-8 seconds it says not in service then gives fast busy signal

Check the alarms?
Re-seat the MBM?
Try another MBM?

If it has been working for two years and now quit and nothing has changed, then do what curlycord suggested.

Reseating the card did it
thanks

Good fix.
I had a customer who complained of similar things. After much head scratching, that was the solution. Turned out that they'd dropped a heavy object on the system and the trunk card had dislodged. Two weeks later, they did it again!

They learnt after 2 invoices!
