...so it's not like they're going in blind and just having to take your word for it. The engineer on the day should definitely be phoning the OR internal helpdesk who can log into the DSLAM and check stuff like that.
Forgive me but I cannot help but think that they are "going in blind".
They arrive, they plug in their JDSU and do a PQT. It passes and then they leave.
The one I had most recently said that if those tests pass, that is all they actually have to do. As he said, "you're just wasting time" if the tests have passed.
They don't really have much interest in what I have to say at all.
I'm hoping eventually I'll get an engineer who will do more than just run the tests and go: I know they're out there!
