Westell Diags

Someone posted that there is a util for the Westell B90-36R516 that shows line status and errors. Is this different from the one that allows you just to change the VPI/VCI setting? I am goin' freakin' nuts looking for it. I got the modem from Earthlink with no docs or software.
If you have the diags, can you let me know?

Thanks

Craig Brauckmiller

You have PM, its different from the PVC changer. To see the added info you have to have the modem connected directly to the pc, open the software, press Ctrl+Alt+F7

Jtater,

Cool util. Kudos for letting people know about it.

I'm back up to speed after a 5 day slowdown and found this tool to be very useful.

I'm using a Verizon (East) 1500/128 ADSL line.
The stats are from my Westell B90-36R515-01

Bootstrap 1.00.00
Firmware Ver 06.01.02
Tranceiver ModemAlcatel Firmware Ver 3.8.124

Noise Margin: 30.0dB up / 12.0 dB down [**]
Output Power: 12.0dB up / 20.0 dB down
Attenuation: 31.5 dBm up / 49.5 dBm down
Data Rate: 160 kbps up / 1792 kbps down

I have seen deviation only in one reading, "NOISE MARGIN Downstream: 11.0dB - 21.5dB , usually hovering around 16-18.

I have one question, pertaining to the noise margin in dB. From what I read, it can be thought of as a safety margin. Am I right in the presumption that a higher reading is better?

TIA

Sedated - you might want to look at this thread where I asked the same question (sort of).
»Interpret Modem line stat values

Thanks goes to Jtater for the diag. util.

Thanks, appreciate it. I did a bit of reading about HEC, CRC errors and the function/meaning of each. Good stuff to know. And yes, even though I got the software from 93254336 See Profile, without Jtater's help we probably wouldn't know it exists

Be well,
Sed

Looks good to me... that should support 1500/128 reliably (at least from the perspective of the ADSL link itself).

Just to post a note,

If the above discussed Westell Diagnostic Icon (c) utility [Modem Browser] is mirrored here.

It will only be of any use to owners of deprecated Westell ADSL bridge models A90-36R515 and B90-36R515/516.

Use the utility at your own risk. Don't change VPI*VCI or other virtual channel config. You'll only render your connection useless until they are returned to their old settings- this is not a tweaking utility.

It will however allow you, an owner of a product and a subscriber of an ADSL line to have some gauge of your line's signal levels and performance, a common feature in newer products. After installation, focus on the program window and press CTRL-ALT-F7 to view line statistics.

If you're an owner of one of the current Westell ADSL models A90/B90-2100 Westell has made the A90/B90-2100 (current models) diagnostic utility at their website here (*mainly for Verizon users but applicable based: »www.westell.com/pages/verizon.jsp

Cheers all!
Sed
PS
[I believe this to fall within the fair use boundaries as I paid for my modems as many others and continue to pay in the form of monthly bills. It provides the customer a valuable diagnostic tool which can save both us and the ISPs some time. Of course I will remove the utility if asked by the copyright holder.]
