Kinda nice to get a no sync/intrmntnt sync with an MTU MLT test. Usally an easy fix . :)]]> http://www.dslreports.com/forum/remark,20454644 Thu, 08 May 2008 23:52:08 EDT Re: [General] ADSL Drops When Phone goes Off Hook http://www.dslreports.com/forum/remark,20436637 d_l : At one time, they were used for remote testing (the initials stand for Maintenance Termination Unit) of the line condition up to the NID. I don't know if they still test through them, but the MTUs are disappearing one by one from the network as they are incompatible with DSL service and must be removed.]]> http://www.dslreports.com/forum/remark,20436637 Mon, 05 May 2008 20:11:23 EDT Re: [General] ADSL Drops When Phone goes Off Hook http://www.dslreports.com/forum/remark,20436600 gr8pumpkin : Thanks to all who helped me. I was able to open up the phone company side of my box and unhook the MTU. I then used jumper wire from the posts on the AT&T side over to the customer side and into the module.
It was a bear getting the AT&T side of the box open but a small screwdriver and some needle nose pliers worked just fine.I am back up and working with no ADSL outages when using the phone. I just unhooked the module so I did not have to splice anything.

So what was the MTU for anyway?

Thanks a million once again]]> http://www.dslreports.com/forum/remark,20436600 Mon, 05 May 2008 20:03:27 EDT Re: [General] ADSL Drops When Phone goes Off Hook http://www.dslreports.com/forum/remark,20431054 leibold : To prevent problems later on (due to deteriorating connections) it is recommended that you use gel-filled moisture resistant splices .

If I just need to cut it out and splice it then no problem. Is there anything else I need to do? No extra filters to install like in your resedential install?
Thanks

I could take it out myself but probably should let the company do it.
Be aware that it will probably be mid-week before someone in Direct can get to your post. Then they have to schedule a truck roll so it could be late next week or even the week after before it gets fixed.

Since you aren't that dumb :D maybe you should reconsider doing it yourself.

If you have an MTU, it should be removed by an AT&T tech. The techs in AT&T Direct: »/forum/sbcdirect can remotely test for the presence of an MTU and arrange for its removal. You must be registered at DSLR (it's free) to be able to post a Trouble thread in Direct.

Normally these are discovered once a new user starts DSL service, but sometimes they can "lurk" and not cause problems until months or years after DSL has started.]]> http://www.dslreports.com/forum/remark,20313768 Thu, 10 Apr 2008 15:59:12 EDT [General] ADSL Drops When Phone goes Off Hook http://www.dslreports.com/forum/remark,20313624 anon : My ADSL drops whenever I answer the phone or make a call. While I am on the phone it comes back up until I hang up. Then it goes off line again for a minute before comming back on line. I have replaced the filters and unplugged all the phones except 1.
