No dial tone, but DSL works

Was suddenly contronted with the Sunday a.m. Verizon is of little/no help, except to say they will send a tech out on Friday the 18th. Situation: 1.No dial tone; unable to place outgoing calls 2. All incoming calls are diverted to VZ provided Voice Mail box, where they are available for retrieval if I use a second off- premises phone and call in using VZ's procedures. 3. My DSL works fine. It is not a home run from NID to PC, but is simply picked up out of the wall. My understanding of this phenomenon is that since it is digital, it is duplex over one wire and that is why it is still working

Factors bearing on the problem: 1. Have checked out 2 telephones by taking to neighbors house. Using either one, plugged directly into the NID, situations 1 and 2 above remain unchanged 2. Have unplugged, house from NID. Situation 2 remains unchanged.

Was sort of hoping there was a lineman out there who could provide some advice. If anyone is aware of a better forum in which I might seek advice on this, I would appreciate it. Trapped a couple of VZ repair folks in their truck this morning. They said that given the circumstances, there is probably a short in a line between the C.O. and the NID.

This is how DSL works: line phones simply uses analog portion of the phone line up to 4KHz. It is fine for normal conversation and has been this way since telephone use started almost a century ago. There is still a limit to voltage level in USA and it's why dialup modem are limited to 53k. dialup can't go any faster while using the bottom

4KHz portion of the phone line.

DSL gets around the FCC regs by using the phone line at higher than

4KHz. As long as the filters are in place, existing phones will continue to work below 4KHz and DSL using the bandwidth above 4KHz. All of this while using only 2 wires from nearby switch box or whatever to your house.

Since your DSL is working, the land phone line is probably fine. The problem could be with the switch box, somewhere after it separates the DSL signals and analog signals and routes them. Or the phones you have isn't working. As I'm not an expert in phone system, either someone else here can figure out your problem or you may have to wait till Friday for the techies to check your telephone out.

Thank you for you input.

Interestingly, the problem went away, announced by a computerized phone call at 5 p.m. yesterday. I tend to go with the person who suggested to me separately; "It is probably a short, but don't be surprized if it suddenly goes away and everyone stands around looking sheepish while no one admits to having fixed anything." It cleared up after, per the instructions in the phone book, I emailed their consumer complaint folks and told them that having no 911 for 5 days was totally unsat, and the next email was going to the SCC, just as they provide for in the book. I also stopped by the C.O. yesterday and talked to techs who were sitting outside in their trucks: They told me that DSL will live with one wire, and that it probably was a short. I found that calling them is a farce - especially when you have no phone. In my initial trouble call I discussed with the "agent" at great length all I had done to I.D. that the problem was outside my premises. When I finally found out how to handle the situation on line therough their repair page, I called up the report, and it contained the following: No dial tone This morning, that same page still contains the same information, with an ETR of 1800 Friday the 18th, in spite of my having updated it and their acknowledgment that they got the update. And the repair history indicates that no repairs have been associated with my number for the past 14 days.

Your modem has crapped out. If the tip of the subscriber loop were open, you'd have no ADSL. If you cannot draw dial tone, there's something local in your setup that's cooked.

Do you see -48 VDC on the tip and ground on the ring? What do you hear from the telset when you go off-hook? Did you plug your telset directly into the RJ-11, bypassing the ADSL stuff? These are very, very, very basic telephony tests that should be done whenever a line's in trouble.

And yes, I have over 25 years experience in the US telephone industry. "Tip 'n ringing" with POTS phone lines is a little below my level, having been mostly in long haul analog coaxial cables systems, terrestrial microwave and C-band common carrier satellite, both DOMSAT and INTELSAT.

Trouble coding: CCWH...."Came clear while hoping"

HAHAHAHA! Welcome to the wonderful world of "deregulation." They couldn't give a crap less whether you're happy or not, or if you have

911 service, or anything else...just pay their bill on time. Deregulation has taken any responsiblity for good service off the backs of the corporate idiots now running the US telecom market, and makes it a "hey, you take what we give you" proposition...exactly what it was before stringent regulation came to bear in the 1930s.

Probably an intermittant at a pedestal or something else. Nothing is maintained anymore, so nothing would surprise me. One pedestal on the feeder that feeds my area is laying out on the ground, having been run over by a county motor grader. VZ came out and wrapped it in duct tape...that's the repair.

Do NOT ever support any more "telecom deregulation" bills. If you do and they pass, service WILL get worse than it already is.

Then we'd have to wait for a lawsuit to get the companies back on their toe. I wonder how much a lawsuit could cost if it can be proven the telephone company knew of the problem and didn't fix it for so long, preventing someone from calling 911 and a person or 2 died in the process.

Greedy lawyer + sympathic juries = lawsuit with 7 or 8 zero's after a number.

Now that you have postured yourself so well, perhaps you would like to learn something you missed in those 25 years....... Negative voltage is typically placed on the Ring wire, and is referenced to a Central Office "ground" on the Tip.

He says: My DSL works fine. You say: Your modem has crapped out.

I'm sure there's an explanation somewhere for that interesting diagnosis: if his modem had "crapped out", how could his DSL be working fine?
