We have a large installed frame relay network and typically use 2610's at the access layer. AT&T is our f/r carrier and on a site which had been going up and down for over 3 weeks we were having trouble getting them to acknowledge a problem.
We finally stumbled across a tech who had 'heard' of cisco and asked us to enter the command:
Service-module t1 fdl att
This allowed him to see information from our csu according to him. He was able to determine that a lec needed to be dispatched...
Could someone explain what this command actually does and if it is a good/bad/indifferent thing? Also, does it present a security concern?
