[Asterisk-Users] Hum/bux on line

[Michael Welter]

Rich Hi,

After Qwest pronounced my circuits as within spec. (yes, disconnected 
from the house) I listened on the lines with my butt set.  Clear of all 
noise and hum.  I then got my box of Cat3 and laid a circuit around the 
outside of the house and into my lab.  Still clear of all noise and hum. 
  I then connected the circuit to the Adtran and made a call.  Lots of 
hum and buzzz.

As I said, I replaced all the Adtran components with no effect.  I then 
switched the Adtan with one at a customers site (Saturday night.)  The 
customer lines were clear of noise.  I brought the customer's Adtran 
back to the house and still had the hum and buzz.

I've tried to talk with the Adtran folks but had problems finding 
someone with the knowledge.  What I'm thinking now is to hook up two 
Adtrans nose to nose, analog FXO port on one box connected to an FXS 
port on the other.  This will simulate the digital->analog->digital that 
I have with the Qwest POTS lines.  I'll have to buy another T100P for 
this test :-(

Thanks for your responses.  I often wonder what this world is gonna be 
like when the technical guys like you leave the scene.  From my view 
from the outside, looking into Northwestern Bell/Mountain Bell/U.S. 
West/Qwest for 35 years, it appears they've surplused all the talent for 
low wage youngsters.  Not to critize Qwest employees--the people I've 
worked with are highly dedicated and do everything they can to satisfy 
their customer.

The Qwest guy had this handheld test set that you talked about.  He said 
the garage manager confiscated his VOM when he was given the test set. 
Narrow thinking by management, wouldn't you agree? Oh well.

Again, thanks for your insight.
Mike
