No, I am not sure if CDP on R1 can see it. I did not witness CDP on R1 (I
am in NY and equipment is in Orlando). What kind of problem receive pair
on R1 may have if Serial on R2 is up/up and CDP on R2 sees R1 ? I called
telco before many times and they tested lines - tests came okay and I let
them go. Can anybody tell me how I can test line end-to-end from t3
controller ?
