True BUT.... the -48 source is there to get sufficient loop current with a long loop. What the Original Poster must do is measure the loop CURRENT with the POTS set on the KXT, and compare with that current on the trunk. You might also try reversing the polarity. I have no idea why a set would perform badly [vs not at all..] with swapped polarity, but it is easy to try. -- A host is a host from coast to [EMAIL PROTECTED] & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
