I have an Access 9.1 system. I just swapped locations with an analog phone and a digital phone.
All our lines are punched down in the server room so we just swap the cables around. -- That all works fine
The digital to analog was fine. - And I know the wires are different. The digital only uses the outter pair (line 2 on analog) So I made a cable so one end has the pair on the outter and the other end they are on the inner pair. That all works fine.
Now when I put the digital in where the analog was nothing happens. I am using the original cable which also works on other phones. Check all my lines, phone .. everything is ok. So I make this line analog again. Plug in a two line analog phone and get dial tone on line 2. So the line works but it wont work as digital.
The location I am now trying to use the digital phone is new construction and only had the analog phone in prior. This line is three levels away from the server room.
Other digital phones work fine on this level.
Is there a length limit on digital? or a way to test the signal? Volt meter reading or something.

You probably have the polarity switched. Try re-terminating w\ flipped polarity.

It sounds as though the outer pair are still patched to an analog card (SLA). They need to be patched to a digital card (DKSC). Check how it is connected to the PBX. You can't send digital and analog down the same pair.

Superfoneguy: If the pairs are flipped would the analog still work?
Dfleschute: I don;t have both going down the pair at the same time. I manually switched them.

Analog ports don't care about polarity; Inter-Tel digital ports do.

Is there an IDF in between? Maybe both pairs weren't punched on the original installation. Can you tone from end to end?
