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? thx __________________________________ Do you Yahoo!? New and Improved Yahoo!

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
To all, I tried the attenuator and they failed to provide any relief. Philip --- Alex Bligh <alex@alex.org.uk> wrote:
