Verify Operation of NIM-VAB-A

Hello,

 

I have a NIM-VAB-A that doesn't seem to be working based on the following output, but I don't have an ADSL line to test it with yet. Here is the sh cont VDSL 0/1/0 output:

Controller VDSL 0/1/0 is DOWN

The chip and modem vendor information is blank. Is this normal when no DSL line is connective and trained? Is my NIM-VAB-A defective?

 - Make sure to use the latest firmware available for the device. Also I would strongly advice to check if you still have issues once a dsl line gets connected.

The NIM xDSL cards and xDSL cards of previous generations do not require a firmware file to operate, as they come with preloaded firmware. This card seems to run an embedded linux system and the firmware is the image.

 

The firmware I'm using with it is the latest, but you need to read the release notes as the latest version isn't always intended for your region/DSLAM, as this was the case in previous generations.

 

There are two types of firmware. One is "PHY" and the other is "regular" and the configuration guide really doesn't explain the difference between the two. Do you know the difference? The guide is here.

 

But the question is, without it trained, should it display blank chip/modem vendor IDs or is the card defective? The previous generation shows at least the downstream channel modem/chip IDs.

 

Thanks.

                          - Defective or nor can only be determined by doing the final test....

What I am asking is if the blank chip/modem vendor IDs without the NIM-VAB-A trained is normal behavior or not.

 - The only further argument I can make for my case, is that if you look at the examples in the manual , the Vendor ID is always displayed when the line is  up.

I was hoping someone with a NIM-VAB-A that they knew was functional can provide the output when not trained.
