Eircom signals

What you guys think of my DSL signal ? drops every half hour :-(

Line State Up
Modulation DMT
Data Path Interleave

Downstream Upstream Max Allowed Speed (kbps) 1536 384
SN Margin (dB) 7.50 12.00
Line Attenuation (dB) 54.50 31.50

CRC Errors 2191 3 :(

You want high SNR and low attenuation. I'm afraid that you've got a pretty crappy line there.

Are you on a 1Mb, 2Mb or 3Mb package?

3 megs but I am well aware I aint gettting close to it!

what are CRC errors? and can this be fixed? could it be a wiring issue? or unlikely?

Your line won't support a 3Mbps signal.

The Line Attentuation figure is a measure of how weak the signal has become - basically the longer the line, the higher the attenuation. And you've got high (but within the limits) attenuation.

CRC errors are "cyclic reduncancy check" errors - an error detection method that indicates that the modem has noticed errors in data that it has received on the line.

It could be a "bad wiring" issue, or it could simply be a "long wire" issue. Do any of your neighbous have DSL? If they all have high attenuation numbers, then you're just too far from the exchange to get a 3Mbps signal.

I've Eircom on the case ! see how it goes!

I will give them a chance to test it out!

would DSL 2 sort this out for MAdong ?

If he could move his line to a country where ADSL2 was available, maybe.

Of course if his line was in a country where ADSL2 was available, maybe it would be in better shape for use on "regular" ADSL.
