X-

Program the last station port as IST. Take a GOOD cord from that port and plug it into CO1. From a digital staion try to pickup line 1. If you get dialtone go to intercom mode on the digital set and dial the IST port. Should ring line 1. Try it on all CO ports, That will eliminate 99.9% of customer PBX issues.

Xcountry,
Seems as though the bottom line is that you have dial tone right up to the end of the mods on all four pairs for all four lines, correct?
Your third line will not produce dial tone (that can be heard) in any of the four co ports, and the other lines do, correct?

ComdialJim is talking about what was called a SLICK Eight. Now called an “AML” “Only two lines on one pair of copper today” but you may not have them. Verizon will only give you a bill if you have dial tone on the 21x with your test set anyway.

Anyway, you tested two KSU’s, and what are the software versions of both?
Make sure you have at least DD. (XAODd) or do an upgrade.

Try
1- One dial tone at a time in all ports
2- Re-initializing the KSU, and check dial tones on first station port with direct line access before programming anything.

Did both those Hud! Dont recall the software versions atm but both brand new systems. I have a vendor meet tomorrow with verizon. I will post results as soon as I get home!

DING DING DING!!!!!

ComdialJim is the million dollar winner!!!!! Verizon is using "Lightspan" to bring dial tone to that area. Its fiber from the central office to a node were its converted to copper and sent to the dmarc of the site. He tested both new lines and both were being supplied by the lightspan. The other three dialtones were straight copper runs to the central office. So I had him move the first questionable number to copper and boom theres the dial tone. I reported it to Vertical but it didnt seem like they were interested. Either way the job is done and customer is happy!!! Wow what a relief!!!

Yep Jim has always provided good info.

Ahh technology at it's best....

I am thrilled to hear that you found the problem, but it is troubling to hear. About 75% of the new developments in our area are using Lightspan from AT&T. I know that I have some customers that use an XTS and STSe without any issue, but hope that it is addressed soon. I would like to put in more of the SBX, but the voicemail is a little lacking for most customers, and this will create some headaches if not cared for.

CS we are averaging about two sbx installs a week. This is the first time ofcourse we have ran into this but the Verizon tech laughed and said better figure something out soon!! There was another post in this section of someone having same problem. He switched the sbx ksu with an sts ksu and the line worked. So it looks like its just with the sbx.

The telcos are saving money by using any form of dial tone delivery at our expense as installers. Thank you for keeping us posted because there may come a day when we can finally stand up against them in a united (and documented) front. Only then will they start to take us seriously.

Sure, this may be a pipe-dream, but still something that we can hope for.

There is one statement that I'll never forget and it came from Vodavi's former director of technical support: "It's always the telco, no matter what they say". He was right then and his words ring true to this day. Their stuff works when connected to properly-working service.

Thanks again for your persistence and follow-up. You have helped many fellow installers and it is appreciated. I think that most of us here agreed that the issue was with Verizon, but since they feel that they are mightier than God, it is our responsibility to prove their incompetence.

I sure hope that you bill the customer for this issue so that they can submit a complaint and receive a billing credit. Don't be shy.
