F9600 displaying unused equipment

[pacmanfourtwenty]

Hi long time reader of the forum, first time posting.

I was hired on about a year ago to manage the voip system when it is in place. i come from mainly a networking background so excuse my ignorance. We have a F9600 and my assumption is the DIS LLO will list DT that are not physically plugged into the wall and SLT telphones that are off-hook. My question is is there a way to identify SLT that do not have a physicall phone connected to a jack on the wall.

I've been dealing with F9600 since 1988 and I've never know a way to do that. There are others on here that know a lot more than I do and they may chip in with a technique. Sorry I couldn't help.

Just a physical trace I guess, all the way out to the end. I think thats way you have to do it.

That is what I was afraid of hearing. The Problem is we have roughly around 1100 analog DN when i generate a report and i know we do not have anywhere close to that much analog equipment and with the VoIP deployment being less than a couple of months away i was looking for a less labor intensive solution that tracing out 50 year old wiring that has no labels or idenifications :/

I hate to make this suggestion.. but. make any extension in question a hot station. With the destination station being an attnd console or a display phone that is always manned. When the phone is used it will ring down to the destination station, and you will know it is in use. Keep track of the stations and check them off as they are used. (remove them from hot station). After several weeks/months you will know if a phone has not been used.

I would say to work it from the other way then, get with your each office manager to see what analog extensions they have, when you've gotten with all your offices, and have a good count of what is in use, cross check that with your list of 1100, and start deleting. Its just a time hog, but if you have to do this prior to lauching voip, its better than check 1100, since you stated you had far less actually out there.

you'd probably have to do that anyway to get a good count for your Voip Analog cards anyway.

as of right now the method we have is similar to what your talking about. we hired a third party company to go around and try to idenitify every digital set, analog set, fax machine, modems etc. i guess after we get that list it will be deleting the ones we didnt find and see if anyone complains

An old thread here but I just thought that I might add a comment...

For analogue equipment, the ring detect circuit that hangs across the line in idle state has a series of resistive and capacative components. Using an ohm meter testing toward the "phone" the power from the meter momentarily charges the capacitance (battery) in the circuit when connected and then discharges. Reverse the polarity of the meter & battery with respect to the line and the the capacitance is charged in the opposite direction and discharges. A linesmans test set would be ideal but an analogue ohmmeter with a line reversal switch wired in would do the trick.

Once you've tested a few phones and faxes etc you'll know what to expect for a phone, or an open, or short circuit line. You can either test the cable pairs, or look back towards the cables from the PABX ports to make your list depending on whether you want to work with pairs, or ports, as your reference.

It will take a little bit of time to set up if you can't get your hands on a test set specifically built for this purpose but once you've done a couple, then you can get through hundreds of tests very qickly.

From memory, a meter with an 80 volt supply, a large analoge meter movement, and a built in reversal switch or button is ideal.

2 microfarods used to be the capacitance value in one phone. Some phone equipment is down to 0.5 uF or even less now I think, but anything under 0.2 uF is probably an open circuit. With the right combination of meter and battery, then an 80% deflection on the meter is a phone, and 10% or less is an open circuit. Flick the reversal switch back and forth to retest. If the needle stays up you have a short circuit, and if it hits the 100% mark with force you have a couple of phones on the same line.

It's very handy to know if there are 2 phones on one line, because you will have to split these services into 2 different services, if the new extension is digital or I.P.

Munz.

Thanks Munz for the suggestion. After doing some testing with a analog multi meter i believe this is the route i am going to go.

there is an svp parameter in f9600 to turn on that will check SLT in the llo list not sure exactly with one

Perform a "dis pkgs" command on each of your sl and dl line cards. This will show you which equipment numbers are in a LLO condition. Then, it's a simple matter of following the cross-connect path to the appropriate wiring closet, and then to the jack. This won't tell you what room the jack is in. But it will narrow the search down to a specific area. And, If your organization has good records, there may be a blue print, or other documentation that shows wich jack numbers are in which rooms.
