Effects of a Split Pair?

[tylan]

I'm mainly a computer tech, but I'm learning phone systems...

The other day one of our installers tried to install a KSU, but the client's site was wired very poorly. They were dealing with three analog business lines (CO/POTS). To top if off there were lightning storms in the area. Needless to say they stopped the install.

When they were left site, the original house analog phones could pickup a dial tone and dial, but could not answer an incoming call. When they would pick up the incoming call there would be dead air.

I think this is purely a Verizon issue, but the Verizon tech pointed the finger at my guy. Could this be caused by my guy a splitting a pair? Such as having an analog phone hooked to the TIP of L1 and RING of L2?

I tried to duplicate this with a butt set and I was unable. What happens if you mix the TIP of 1 line with the RING of another line (or vice versa)?

It could be either one. It is not hard to split a pair and have two dial tones or dead air. But it could have been the phone company sending you dial tone on crappy copper pairs and have one side or the other open. This too is dead air.

OK...


Let's just say that nothing is broken. What happens if you split a pair? When I used my butt set at my office I couldn't get a dial tone across a split pair.

2 tips sides will give you two dialtones. But a two ring sides gives you nothing but dead air. Lets say you connect the first dialtone to the to the first ring side and the second ring side, you get dialtone. Or I should say off my PBX frame I do.

But what if the phone split a pair coming into the building (or a bad pair) from a pedestal on old direct buried cable. Dead air. This is where you would have to go to the demark and pull the bridging clips off and see if it is there problem or on your side.


Either way it happens all the time.

if you can ring and talk at the demark then it is your problem.If you can not ring and talk at the demark than it is verizon's problem. Use some type of volt ohm meter like a sidekick and you should be able to see splits opens etc.
