I have exactly this modem and it's working fine for me with BT's 8Mb service.

Anybody have any ideas on my Netopia problems (above)?

Placebo

theyre advertising it saying people can be on doing multiple things, i.e playing online and surfing the web. I'm on 3mb now and anytime anyone even goes on the net i get lag.

Will BTs LLU have any significant postive effect on latency, interleaving etc?

Any one gotten the 8Mb broadband in Naas yet?

My 8Mb line just got enabled there today. w00t!!! now to test it out.

Here is what my stock "Voyager 210" modem says:

Line Mode ADSL2+ Line State Show Time
Line Power State L0 Line Up Time 00:07:00:22
Line Coding Trellis On Line Up Count 2

Statistics Downstream Upstream
Line Rate 8124 Kbps 507 Kbps
Noise Margin 32.6 dB 31.0 dB
Line Attenuation 8.0 dB 3.0 dB
Output Power 11.1 dBm 0.0 dBm

... and a quick speedtest:

Did you request this or was it automatic, did you experience any dowtime

Looking at those stats and without tempting fate, the only time i could see you getting problems would be if the voyager needed replacing or a problem in your area. I dont think you would see better stats posted here.

Enjoy

I requested it. I was on the 2Mb/s package and rang to upgrade, they said I could move over instantly to the 3Mb/s package and get upgraded to 8Mb/s at a later date, or upgrade to 8Mb/s and have 2 weeks downtime. I took the downtime (I have unlimited internet access in work) It took them about a week to disconnect my old line and then I had exactly 2 weeks of downtime (14 days ago today my line got disconnected)

btw, why is this line so good? Is it because the noise margin is so high?

higher noise = good
lower attenuation = good

Here's my stats, something similar:

Downstream Upstream
Max Allowed Speed (kbps) 3072 384
SN Margin (dB) 25.00 21.00
Line Attenuation (dB) 5.00 3.00
CRC Errors 0 1

Jealous of u and your 8meg tho

Placebo

so how is it mr? shudnt u be getting 800kb,

god sounds amazing

DSL Technology has overheads so you never get quite what you sync at.

Low attenuation as well.

Good stuff! Very impressive stats! I'm also in Swords and on the BT 3MB package. I think I'll wait for the "automatic" switchover whenever it happens.

One thing is my line stats are rubbish and I wonder will I be even able to get the 8MB?:


ADSL Link Downstream Upstream
Connection Speed 3072 kbps 384 kbps
Line Attenuation 51.0 db 31.5 db
Noise Margin 10.9 db 14.0 db

shouldn't your line stats change once they make the change over? I mean aren't BT plumbing in fibre optic cables at the exchanges? Your attenuation and margin should change once they connect you onto that line.

I'm very happy with the line, was getting a steady 830KB/s download last night. It's crazy, I remember when I was getting ~7KB/s and I was over the moon (one of my friends gave me the access details for Gateways internet connection). Ah those where the days, spending an entire friday night to download 2 songs off naptster.

Hey L31mr0d did you ask anything about if they are going to increase the usage cap?

Your line stats are a measurement of the condition of your phoneline from your house to the exchange, nothing else. Every ISP uses fibre as backhaul out of the exchange so that makes no difference to your line stats. If they don't have their own fibre they use Eircoms.

nope... i've never cared about it and never will. I've been at least quadrupling my usuage cap on every DSL line i've had since I started on 512Kb/s back in 2000 and i've never had to pay an extra cent. In the last day i've used up at least 50GB on my 8Mb line.

My friend in work contacted BT looking for concrete information about if they will charge you for going over the cap and he was told that you won't be charged. In severe cases they will send out a warning letter with your bill the first time but you won't be charged, you will then be charged 1 cent per MB over your cap for each bill after that.

There are a few ISP's that do enforce it, but i'm smart enough to avoid them. So far Eircom and BT have never bothered to charge me. I guess they just have it written into the usage agreement so they can fall back on it in cases where people are maxing out there line 24/7

I'm just wondering if there is anyone on the Swords BT Exchange who has/had the 3MB package and has been "automatically" upgraded to 8MB without any warning?

Can you remember what your line stats were before you switched to 8MB? Were they as bad as mine?

50gb in a day :eek:

I've just gone from BT's 2mb to 3mb so that I'll get "up to 8mb" when Eircom switch their gear in June (but hopefully before then?)

How do my line stats look in terms of quality? (i.e. do I have a good shot at the upper limit of the 8mb service?

From my Zyxel stats pages...

"Upstream Noise Margin"
noise margin upstream: 20.0 db
output power downstream: 19.0 dbm
attenuation upstream: 16.0 db

"Downstream Noise Margin"
noise margin downstream: 40.5 db
output power upstream: 0.5 dbm
attenuation downstream: 19.0 db

Upstream Speed: 384 kbps
Downstream Speed: 3072 kbps

They are super stats, do you live in the exchange?

i didnt think the ZyXEL Prestige 623R would work with the new 8mb service because its not a adsl 2 modem. The adsl 2 servers must be backwards compatible.

Placebo

apparently im on the 2mb line

anyway heres details, says its available in my area from 10th dec, im assuming thats 2007 !!!

For you to download 50 gb in 24 hours you must have been downloading at an average of 520 kBps how do you think your line sharing neightbours will be feeling about this?

Abusers will be taking into account, few go beyond common sense BT and possibly the rest of ISPs will change their policy and start punishing abusers, by logic is for the good of every user.

I wouldn't like someone taking 70% of my bandwidth 24/7, remember that we are "sharing" a line, so be warned!

I've the same modem and was told by BT last week that it'll work fine with their soon-to-arrive 8mb upgrade. Not their own LLU, but Eircom's scheduled upgrade. (I specifically asked whether I'd need a new modem/router and mentioned the Zyxel.)

It isn't ADSL2+ compatible according to this...
http://www.ciao.co.uk/ZyXEL_Prestige_623R_T1__6202601
but a quick wiki says that one of the ADSL standards it handles (G.DMT) can go up to 12mbs so I guess that's how Eircom are doing it.

Not quite, but I bet I'm close! I'm on the Merrion exchange in a relatively new apartment block (c. 7 years old).

Anyone have an idea where exactly the Merrion exchange is?
