How did the tech visit go yesterday?

Tricky. Most of them won't look at your BQM if everything looks fine on their signal/power stats.

Just try to make the tech aware of the extent of the issues you're having with SNR (e.g. modulations changing) and power level problems on the upstream.

There's not a lot else you can do. You may need to go through a couple of tech's before things get escalated.

Like the General said, escalation can take time and a certain critical mass of customers complaining. Assuming other people are affected and not just you.

I often take the view with SNR fault's that reporting it then sitting back and let other people do the moaning can be the easier option.

Unfortunately tech's don't have any equipment for tracing SNR fault's, especially intermittent ones. It's just a case of trial and error, plus relying on what the stats on the CMTS say.

It may not be something they can do anything about anyway; Regular tech's can only deal with things from the hub to the local cabinet. If it's further upstream then a network tech/engineer will need to be called in.

At this stage you don't know where the issue lies.
