The line's beautiful.  (When the fault isn't on, they're right.)

When the fault comes in, even 4800 is a problem.  It's bad enough that the
diagnostics aren't stable.  S/N degrades to less than 10db, and the
bandwidth stinks.  Funny:  The fault doesn't cut in unless a wideband modem
is using the line...  9600 or less won't trigger it.  Nor will a 9600 fax -
but a 14400 fax will.

Same exchange - Graham is a problem from here too.  The local loop I have
is only about 2.5k, and it does only about a 3 db loss.  Ratshit in the
exchange, Graham's local loop, the trunk?

(Anyone - got a reference reading for 711/409's inbound signal to you that
gives clues in this area?)
