Right forum for VTG?

From: Ray Cassick

I have never heard of this situation at all and I deal with the DSE VTG cards all the time.

At the time the cards first power up the front end has transmit disabled so it should not be able to send junk down the wire.

Now, I could see this happening if you were to RESTART a system once the cards have been downloaded already. Once the cards are communicating with the PBX, of the boards are reset (as would happen if the system was restarted) the communications channel to the PBX has already been established and is active so any notice that might happen as part of the reset would be exposed to the PBX. This is the only time I have heard of anything like this happening, and it was not on Siemens before, it was on Nortel, who can also be quite sensitive.

That being said, if it is happening to you I can't argue with what you are seeing. How are you concluding that 'sending garbage down the lines to the PBX'? Has someone from Siemens analyzed the PBX side?

Just on a whim, you might want to take a look at your grounding. Perhaps there is some ground differential making it appear like there is data being sent when in fact it is just a difference in ground reference between the PBX and the system containing the DSE cards.
