I was out to the site on Tuesday. Tried the Immediate voice connect, set all the disconnect timers to either off or as long a possible, nothing worked.

There isn't any FIOS here anywhere. The closest I know of is in Harrisburg. The remotes are fiber-fed from the CO 8 miles away.

Also took along a DX120, connected it up, had one phone, didn't program it at all, Lines work, even called a number from it, used the flash, that works, put the other party on hold, and I told them that several seconds after I did, they should hang up, line disconnected.

So I gave up. After 4 trips to the site, (37 miles one-way), I talked the buyer into letting me get a DX120 and change to that equipment. Stuff should be here Monday, and I'm going to install next week.

Beats the **** out of me.

Final thought, VZN says all is OK. Don't know what to ask them to fix. Have a friend who works the offices here in my county, he called the girl who runs the switch where I am trying to install this, and she says she doesn't see anything wrong.

Thanks though for all your suggestions.

CASE CLOSED (I hope!)

The mention of "three clicks" sounds like dial tone from a 5ESS switch, but I don't think they are really clicks, as in the line actually going open momentarily. I think they are just sounds heard when seizing a line. Regardless, that shouldn't have any effect on the SBX. I will say that I don't know if any of our installed SBX customers are directly connected to a 5E office. They are either behind FiOS or pair gain equipment, which masks those click sounds.

I'd be curious to know if your customer's lines or the test dial tone you used on the bench was coming from a 5E line. There are a lot of international settings in the SBX that reference European standards, such as pulse metering, etc. I wouldn't be at all surprised if one of these settings is your culprit.

Most CO switches, cable EMTAs or lines on pair gain return instant dial tone when going off-hook. The 5E is the only one that I know of that does not.
