I am on a 7200 (T3)with a 2600 on the other site (t1).
I am trying to loop the CSU ( or far router) with no luck cannot get it to sync.
I am trying the command: ( from controllers t3 2/1)
t1 9 loopback remote line fdl ansi
I can loop the smart jack with no problems.
t1 9 loopback remote line fdl bellcore
anythoughts? as to why I cannot loop the csu/cpe router
