You mean a Mk2 interstitial VDSL2 filter plate?

If so, to get to the test socket you have to remove that, not just the NTE5A that houses the external phone socket.

The easiest way to connect then is with an old dangly filter if you have one.

In reply to a post by sammyelrefee:

Right.

I went through to disconnect and reconnect to master test. Unfortunately the cable I had borrowed from the phone seemed to have a different wiring schematic to that of the modem. Therefore I never got it in sync. The wire seems to use 1 + 4 as opposed to 2+ 3

I'll need to source a proper cable!

Just to let you know also I have the MK2 faceplate!

Thanks

I presume you are saying that the cable used had a BT connector at one end and a 4 pin RJ connector that some phones have?

If that is the case, it should not matter as most modems are designed to take either inner or outer pair of an RJ14 6P4C (same shape as RJ11) with 3&4 and 2&5 being the pairs in use. Some are auto and some are manual.

Somewhere in the Telnet Interface it is possible to see which pair is in use and if need be, change it using the command: xdslcmd connection --lpair <i> or <o>

Yep you're correct. I replaced my standard one with the MK2 a while back to see if I could improve things.
I didn't think to use a standard filter to connect my modem at the test socket. That's an idea. I'll try find one of them!

Thanks

Correct.

I had a quick look into the RJ11 port on the modem but there are only 2 pins for 2+3. Because the cable I used was 1+4 it can't make the physical connection. l'll try to find a 'dangly' filter out and connect at the test socket (behind the mk2 of course!)

Thanks

Are you sure it is 2&3? It is 6 pin connector and they should be either 3&4 if only two are provisioned or 2&5 and 3&4 if four have contacts.

Ha got it!
I have never realised rj11 had 6 pinouts. I see that now!
The connector I have has connected live contacts for 2+5
However, the reciprocal plug on the modem has only pins for making contact with 3+4 on the plug.
This therefore made my cable totally useless!!

Sorry for the confusion!

Thanks

Right

I have done the test from the test socket now! I had a look and the bitloading and snr per tone graphs remained constant. Still the v like dip
I'm sure that therefore rules out faceplate issues. Tbh didn't expect a change as I had the same issues with the bitloading graph when I had the original vdsl faceplate on.

Thanks!

Are you SURE that you have not been put on a 40Mbps downstream profile by mistake? I know 40/20 does not exist, however an error could have happened.

At present nothing else actually comes to mind.

And I am scratching my head over my connection too ... A rather large notch causing loss of downstream tones 33-39 and bit loading averaging around 6 all the way up to tone 250 where I start to get 14. If I can sort that, I should be able to get another couple of Mbps!

What about the Hlog and QLN graphs?

Also, can you post the basic text statistics, (eg from the Telnet Data-> Connection Stats tab, and the Telnet Data -> pbParams) as well as the basic information about the cabinet (distances, estimated speeds from BTW, etc).

I'm pretty sure. I had BTOR come round a few times and they reset DLM and just left. It would be ok (ie 75ish) and then decline a few days later. My line has never been the same!
However, I may request another regrade again!
