I am having a problem witha DS3 that terminates into a Adtran CSU (T3SU-300) and then into a 7200 with HSSI. I can not ping with a 0000 data pattern and I experience packet loss and errors when I pass TCP traffic.
Adtran recommended an attenuator.
What is the issue here? Is the signalling incompatible with a PA-T3+. Should I be wasting my time with an external CSU?
Last time I looked, PA-T3+ were even MORE fussy about the need for attenuation than the non-"plus" variants (of the "never actually work with a BT DS-3 delivered as standard" sort of fussy). So yes you are probably wasting your time with an external CSU, but you are also quite likely to need attenuators anyway. Alex
