Hi,

I have a customer who went through a major remodeling of their engineering and sales areas and the wiring company pulled out all the wiring before we were able to track down the fax lines. I believe the fax lines go through the phone system as everything is running over a PRI so I believe they were ports on the system.

I look in the programmer and I see 4 ports labeled fax- with no name by them - assuming these are the connections.

I am wondering if there is any way to look at the programmer and determine what pair on the punch block they go to by maybe tracing port / card in the cabinet etc.?

I have a call into my vendor as well but they are usually a bit slow at responding.

Thanks,
Rich

If the fax ports go through the system they are either on a 8SUBS card, or an 044 card. You can trace a the 25 pair system tail from the system, to the block that it is terminated on.

If it is an 8SUBS than all 8 ports of the card are analog and you should be able to follow the jumper cables to the associated station cable.

If it is an 044, then 4 ports are digital and 4 are analog, so you would have to know how the switch tail pins out.

Looking at the programmer can be really helpful. If you can match the system card/slots to the 66 block where they terminate, you can trace ports fairly easily. If you're tracing an ECS, the programmer will even depict what cards and port numbers are in which slot. Hook a butt set up to suspected analog ports and call a digital display phone to double check your detective work.
