Re: Firmware rasied noise margins on 643 Bill,
Here you go
ZyNOS F/W Version: V2.50(AY.4) | 11/08/2002
ADSL Chipset Vendor: Alcatel, Version 3.8.164
Standard: G.DMT
Interesting enough I was doing some digging on Covad's SMART account manager. You can actually get the new firmware for 643 from the covad site. Which is the only place I have seen this.
From the smart manager account
"This file is a firmware upgrade for the ZyXEL Prestige 643 ADSL Router that comes standard with all TeleSoho orders. The TeleSoho firmware upgrade is necessary for some TeleSoho customers that are trying to
1. Change their IP configuration from 1 IP address with NAT to 5 static IP addresses
2. Connect to XBox Live or other online gaming sites."
Bill do you have the 1.5/384 or 1.5/128 via EL? If you are on 1.5/384 how come EL users don't have the 643 out of curiosity?

Thanks for the info. Hall covered the modems pretty well  . I have the 1.5/384 service which is why my SafeMode is 928/384. It's also why I keep my ears open for ways to actually get 1.5m.
BTW, several people around the time I signed up got these "P645" modems from Earthlink. There is no plain-old "P645". Only further research found it to be a P645M-11 (or darn close). I determined this by getting the f/w off the unit and comparing it to f/w on the ZyXEL site - and got a byte-by-byte match! There isn't a lot of desire for ZyXEL or Earthlink to make these custom-ISP models well documented.
EDIT: Notice how your Alcatel Version is 3.8.164? My P645 is 3.8.124. Chances are this refers to the DSP-based chips and/or microcode that actually do the phone line signal conditioning. This is golden info to someone about possible performance issues I'm looking for - finding such people has not been successful. This engineer would love to talk to another inside this technology. I'd run out and get a Bla-Bla model Bla if someone told me it was the most advanced for noise.

| Bill,
I have to agree with you. Zyxel seems to lack good documentation. Also, I agree about the various 645 models. When I was looking for documentation (limited) on the 643 I couldn't believe the list of 645 models. Is it really necessary to have that many?
I must tell you I like the fact I can see the noise margins myself. Other then that I really don't care. |

| Well, GDM And CCarlin - you have the latest for Covad on the P643 - V2.50(AY.4). I found out Earthlink hasn't officially blessed the latest for my P645 (which I got online anyway) which is V2.50(EK.4).
But to the best of his knowledge, no ADSL parameters are invloved in these upgrades. Two people claiming a few more db of noise margin is significant, though.
CCarlin - I'm really curious how your performance is on the new f/w. I may want to have a backup modem before attempting to FLASH my P645 - these ISP-unique versions make me nervous. |

Well, I did it anyway. I'll have days of data for noise margins to compare.
Hey! Looky this...
was:
ZyNOS S/W Version: V2.50(EK.3) | 8/31/2001
ADSL Chipset Vendor: Alcatel, Version 3.8.124
now:
ZyNOS F/W Version: V2.50(EK.4) | 9/19/2002
ADSL Chipset Vendor: Alcatel, Version 3.8.164
A distinct Alcatel revision - maybe there is some microcode updated in the phone line stuff. At least I'm not down!
EDIT:
Holy Cow! It is definitely a jump in noise margin:
1/2 hour ago:
noise margin downstream: 10.0 db
now:
noise margin downstream: 13.5 db
But will it equate with stability in FastPath? A step in the right direction is indicated.

| Sorry, I edited after excitement! I have lots of noise margin data (every hour since last April... no kidding!).
I'll be able to plot noise margin (downstream is the limiting factor) for a week before and a week after, I hope.
