Hi, have a XTS ver 2.2.1 . when you put outside line on hold the outside party hears dial tone right after you put them on hold. You can pick them up, so they are not gone. After a few sec you get a recording saying your call can not completed(at&t is the carrier). Have moved the co lines to different ports and cards. No change. Help

Sounds like a case of crosstalk...happens only on hold?

hi Derrick, I when to the site today. hooked up a single line port to a co port. tested all the co's, all the ports do it but not all the time. A bad CPU card. it is incoming and out going.

Could be time slot failure but that should effect more than just the cos. You would get crosstalk between extensions. Maybe your MOH port is acting up.

So if understand you correctly, when you take the caller off of hold, you also hear what sounds like you have conferenced with another line? And then that 2nd line times out and you have a 3-way? The 1st call plus the intercept message? Does the howler (or similar) tone then intrude on your conversation? Will the caller also hear that intercept condition if you just leave them on hold for a while?

I'm thinking your hold button is kind of Flashing the CO every time you press it.

Perhaps you could try a shotgun approach and turn off anything that affects CO connections. I would think of things like DISA and all station conferencing. But most of all, try changing the CO Flash timer. 01 is short and ignored by the CO. 20 will hang up. This should show if the MPB is delivering a flash signal. You may also want to check the CO Loop Supervision.

thanks MnDave, will look at that this week.

The xts allows one flash button per phone, and the actual hold button can't be a flash key. Exactly how is the call being put on hold? That may sound like a stupid question but sometimes people hit keys they shouldn't hit when trying to do something simple.

Yes Derrick. I know that but. but I've never encountered this problem so I am approaching it as if his system is developing a database or CPU problem. But starting from square one is always best.

Another thought... I just reviewed button assignments on my 3015-71 and see button 41 is assigned [Hold]. What if his Hold is assigned for [Flash]?

Try the old button test and find out how they are programmed:

Lift the Handset, Press Speed, then dial 7 plus #. Dial 2 to select KEYBTN option. Press the desired flexible button or buttons to display programming for the button on the LCD. When finished replace the handset.

added more info. when i put a call hold the the call(outside) gets ATT dial tone. then times out because they are offhook. what does the XTS put on the co line for hold. does it about 90% of the time. All phones and all co lines
tom

Putting a call on hold doesn't introduce anything into the phone line. I have seen other manufacturer's systems drop lines on hold because there isn't enough loop current to maintain the line seizure. I've never seen this occur on any XTS equipment and you do appear to have ruled out the LCOBs. Have you checked the loop current between an active call and a call on hold? Have you tried Derrick's button test yet?

I am pretty sure you have a time slot failure....have you reset the system?

going out tomorrow, have powered down moved LCOB no dif. will let you know
tom

You know unused co lines can be programmed as MOH sources. Is it possible that was done at some point and now the line is live again? If so the system maybe connecting the co as MOH when you put someone on hold, they would get dialtone and then the line times out and starts howling. I bet the caller on hold might be able to dial a number!

went out to the site.swapped out the cpu card, no change. checked the co settings. the co lines were programed for MOH #1, they do not have MOH. change from 1 to 0 and the problem is gone.
a first for me.

MOH ports 1 and 2 are on the MISB card. That card could have tdm errors.

do not have a MISB, but fixed
tom

I started to ask if you had an MISB installed, because missing will cause this is if MOH is enabled. I didn't think of it at first because the MISB came standard with all systems for years.

Derrick - good job! I didn't even think about MOH. And ditto on the MISBs. I can't recall that I ever had a system installed without one. I even still have spares because I always ordered packages whenever I needed an expansion KSU. They were basically free at that point.
