Re: Bumped down with no help from Acanac
Here is the lantern for the line in question:
Speed (Kbs) Relative Capacity Occupation (%) Noise Margin (0..31 dB) Signal Power (0..20 dBm) Attenuation (0..60 dB)
UpStream
800 75 16.0 12.0 23.0
DownStream
5056 94 8.0 15.0 39.0
------------------------------------------------
Note that is interleaved 5M.
On Fast Path NM are down and streams cap.
Bell said that is the best they can adjust for the moment.
Please give me suggestions how can I improve the things.
Regards.

lantern:
capacity: 1066,5378
SNRM: 16,8
* * *
The line capacity seems to flip between 7360 and 5378.
Clearly there are line (noise) problems, and the two instances of switching to Interleaved and rate reduction were reasonable measures, given the severe instability each time.
In particular, capaity changed from 7168 to 5378 over the past week!
Line quality needs to be looked at -- likely first step: check at demarc to isolate problem to Bell or Customer wiring.
My immediate recommendation would be:
1. customer check modem stats right away to confirm lantern data!
2. customer consider doing modem check at demarc. | |

| planiwa, thank you for your comments.
This line shows 39db attenuation at DS.
As you see, it is relatively far, and some performance fluctuations are present.
But currently, it "works" and gives a "5M service"
Maybe, it could be capable to perform fastpath and/or 6M downstream, but very often, if we submit a "trouble" (for that working line) to bell, they may downgrade the profile even more as they usually said "to be more stable". Field technician could be dispatched, too, but everything depends of their support people decisions and priorities.
In this particular case, the user is a business one so queries for 6M are reasonable and I would create a new ticket.
Just before that, as you suggest, we need to make sure at the user side everything is checked.

It's NOT a distance problem like "Acanac PN" said. 
As you can see by "Acanac PN" reply, he said "it works". That's all acanac cares about. They won't go an extra foot to help this person resolve the problem.
A problem exists and acanac and "Acanac PN" blew this guy off.
My recommendation would be o dump acanac and their horrible support.
94% occupancy, Max attainable jumps by 2-megs and Acanac PN says it's "a distance problem".
gimme a break.
Ask for your money back and leave them for non-support.
end of story. | |
