Thanks for responding pvj. I'm afraid I'm a bit lost on the w/bl w/o. Is that white/blue and white/orange?
I took my phone apart and see that the jack is wired with the usual red/green/yellow/black. How do they correspond to the scheme you have?
My punch down block has 50 positions, corresponding to the 25+25 connections on the plug that attaches the punch down block to the EZ-1. Do I skip the first two positions and start punching down on the third?
I found a cover for the punch down block and there seems to be a sticker that says the first two wires for an extension is tip and ring, the next two seem to say DA and DB. Does that make sense to you?
Is there a schematic somewhere I can get? Do the install manuals available for sale include what I need?
I'm sorry but am a bit desperate as I need to get these phones working soon. Thank you for any help you can give.
