Toning telecom wiring, tone dies after final punchdown 1

[Dhoeving]

I'm incredibly new to telecom and was running a connection from an end-user's office to the server room -- and the Mitel 3300 system. The line passes through three wiring closets (including the server room) so I connected my tone generator at the office jack and checked for tone at every connection. I had a clear strong signal at every block -- including the server room -- until I punched the wire into the actual connection to the phone system, then the tone died all the way back to the first punchdown (I still got signal at that point). If I pull the wire everything tones again.

I've checked to ensure that I haven't crossed the wires when I punch them down.
I've moved the wire to three different locations in the phone system -- same result each time.
I've replaced the wire twice, and tried pushing the wire (like dental floss) into the punch down to avoid accidentally crushing the wire -- same result.
I've plugged in the phone to see if it powers up regardless -- it doesn't.

What am I missing? what steps can I take next to troubleshoot this issue?

That is pretty much normal for a Digital phone, and Network Ports if your running VOIP

We are running some VoIP phones -- Mainly 5220s, and 5330s -- but mainly digital phones, and I've tried toning several other lines and they don't have the same issue they give a signal all the way through.

Some phone ports load the loop in different ways, and/or battery feed circuits, when you connect the pair with a tone trace source. So that is not too unusual for that condition to occur. Did you connect the phone and does it work?

SYQUEST: I connected the phone, no power to it.

Have you changed the TN

Are you sure it is the correct port? Can you get the phone working directly on the 66 block bypassing your wiring?
I bet the port is not configured on the phone system or you are connecting to the wrong card.

PerryPJ: the TN? I'm not certain what that is...

whykap: Its punched down to 5,1,2,4 (cabinet, shelf, slot circuit) and the port is set to the device Superset 4025, Interconnect is set to 1, as is the tenant number... it is to the best of my knowledge configured correctly (I've double checked the location)... As for connecting to the 66 block bypassing my wiring I would have no idea how to...

I have exactly 6 months of hands on with telecom and no mentoring or training... my company "downsized" our previous telecom guy and since telecom involves wiring, ports and switches the network admin was the "obvious" choice to inherit the responsibilities... please bare with my ignorance...

Sorry I don't know what Mitel calls there ports

Take the phone back to the phone system, and bring along a jack with a few feet of cross connect wire. Punch the jack to the port on the MDF where you are expecting the phone to be connected, and plug the phone into the jack. Does it work? If not, you need to solve that problem first. If so, put in your jumper to the first IDF, go there, pull the jumper that goes to the next IDF, and try your jack/cross-connect again. If it works, replace the jumper and move on, until you finally get it working at the desk.

What is 5124? It's not ethernet or RJ-14, so that could be something, but I suspect that it only need 5&4. Either way, the toner only puts the tone on the center pins.

I have that same problem on my Siemens system but the volume just drops about 50% and I need to turn the volume up all the way on the tone wand. Have you tried cranking up the volume?

How old is the battery in your tone generator. I always forget to shut mine off, so I go through batteries frequently.

The switch will absorb all the tone. That's normal. Pull the jumpers from the switch end and you can tone to your hearts content. Don't believe it makes any difference analog or digital.

TouchToneTommy: Thank you that was brilliant...

I stripped a phone cable down on one end and punched it into each of the block back from phone system to dropline, and at each step the phone powered up and got the correct number... It looks like in the end it was a bad punch job -- in the last wiring closet when I repunch the wires after testing the connection the phone in the office booted.

Thank you all for your coments and insights.
