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

Adtran recommended an attenuator. What is the issue here? Is the signallingincompatiblewith 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
