Intermittent failure

From time to time my line keeps dropping out. It appears to be
associated with heavy rainfall. Could I have a problem on the
connection to my house? I am 2.5 miles from the exchange, and connect
at about 2.1 Mhz

Any ideas anyone?

Fred

definitely.

A flooded underground conduit and a poorly sealed cable will do this..

In fact at our sorts of frequencies, a cable perfectly sealed but
running underwater, will affect HF performance.

I have noticed variations with temperature.

Also thunderstorms will knock you off line. `Generally you resynch at
the same speed tho.

When I lived up in Flackwell, every time it rained very heavily, I lost my
broadband connection for however long it took Tiscali to get someone out to
the exchange and fix it.

Water in the underground ducts and street cable, if off a pole
with a dropwire maybe the junction box at the top of the pole.

Or the junction at the fix, or the leadin, or even the ingress of water
where the external is connected to internal (oops I nearly forgot, overhead
going thru that tree in the front garden, it could be there)....Any
externally run extensions??? If so the ingress of water there as well. Any
sockets on the external walls, damp......

The list goes on, the problems can occur anywhere & it isn't neccesarily in
the external network, it can be anywhere & the end user has to do the same
checks as normal.

Oh by the way, if you do have a tree in your front garden which is rubbing
the dropwire, it's your responcability to make sure it doesn't damage you
line, it's entirely a different matter if it's in any other position.

Good point.
Whereas the electricity companies employ contractors to cut back trees that
grow near to their overhead lines, BT will only act in similar circumstances
when this actually results in a fault being reported.
Good economics, bad customer service!
