What error messages & alarms are you getting against board 02B16?

If you run tests against the board, do they pass?

Since these are coming in on a DS1, maybe they should be configured a tie trunks instead of CO trunks.

Heres the board test results & the List/Trace below.

I changed from CO to TIE re; "4merAVAYA" advice after I fail on the call the ports stay active like theres no hangup goin on? Help~! Once agin these are not ground Start but Loop Start analog lines 8 of them

Truns out I was using the wrong board I found an unused TN747B took out the ds1 loaded defaults to the card works. My punch downs were consecutive instead of spaced apart on the wht/blue d10 block corrected those now everything works

Thanks for you input
