Been a Broadcast Engineer for 20 yrs but still a newbie at this telco stuff, we (I) have been given the responsibility of maintaining this old PBX at the station and now have a problem with outgoing long distance. Local long distance is fine. Not sure what has changed but appears that I have one card (first outgoing long dist lines) that tries to seize, but does not GS the line. I can put my butt set accross the pair, then the PBX will get dial tone and dial. Where do I start to trouble shoot this??? I can butt set the line and GS just fine. But the PBX is having trouble on this card. Tried swapping out the GS line with a different line, but trouble stays with the card!??? Looks like all 4 lines on his card are doing the same thing. What has changed. Nobody has been working on this thing. Software? Looking for advice? Thanks, Ken.

forgive me for stating the obvious. can you swap cards? have you changed providers recently?

If the lines are ground start polarity on the line will make a difference on the Perception system. We have had problems with the phone company doing cable changes at the street and reversing the pairs.

Guys, thanks for the help. Looks like Ma Bell can be blamed on this one. Rolled the line, and now works fine. Thanks for help. I dont suppose anyone here has schematics for the ATTENDANT station????? Very low audio from headset mic as well as handset mic!!???
