recovering analog tn's 1

[georges392]

hi guys

i'm running out of analog tn's and i'm pretty sure i have lots of live extensions that are unused with no phones plugged in is there a way of knowing how to do that i read a post talking about a frame test !!! can u guys elaborate on that or other methods


thanks

Forget the frame test, there has to be a old ringer out on the line. You can use a analog multimeter to check for a capaciates kick (old telephone trick). Your best bet is to check your CDR records for outgoing and incoming calls to those stations. No traffic, not being used!

Not easy, but possible. You need to measure "current" by breaking one left of the crossconnect and putting a meter in series with the line. Then call the DN of the analog line and measure the current in milliamps.

You'll need to establish a "norm" so you know what "No phone - no modem - no fax" at the end of the line looks like, and what a "phone, modem or fax machine" plugged in looks like - on your meter that is.

You can successfully detect even a PCI modem using this method - and of course any phone that exists.

You can set up a "rig" of sorts to do this if you have 100's to check: get a 25 pair mail to female amphenol ended cable and cut it in half - punch it down on each side of a 66-style split block and plug things in between the IPE shelf cable and the cable that goes to the MDF - then you can analyze 16 ports one by one without pulling any cross-connect wire off.

Electronic ringer, modem, fax, gum, peanut butter, just about anything you could ever fit into the jack can be detected using an "milliamps with meter in series while ringing" test.

Just out all of your analogue TNs and wait until someone complains.

Unless I am getting CDR on any Analog phones, what I do is disable 20 phones at a time and wait for someone to complain and then enable it. After I have done them all, the ones left I trace the crossconnects to the closets and jacks.




This is a Signature and not part of the answer, it appears on every reply.

This is an Analogy so don't take it personally as some have.

Why change the engine if all you need is to change the spark plugs.

You you, another creative way is to

1)create a voice mailbox with DN you can call to go right to leaving a message.

2)Set the suspect analog TN to FTR HOT d n NNNN (N being the extn of the mailbox/DN.

3)Check the mailbox every so often, then from the caller information, you can tell the extn of the analog line that someone tried to use - because when they tried, it hotlined to your special mailbox.

If you're in no hurry to recoup these ports, I would just disable the entire card and wait a few days. If there are no complaints, you've got 16 free analog ports.

Definately. It woud save on fax paper, security system call-outs, and finally stop those pesky employees from making all those pointless calls they make.
