Thanks Bob,
This has been very frustrating to me, because I have tried to experiment
with DSL to one of my branch offices, but because of their location, they
could only get IDSL through a third party DSL provider, and as you might
have heard, Northpoint went down, and when Rhythms took over, they went down
too. After 9 months of DSL nightmare, I decided to go back to a more
reliable WAN, and ordered a Fractional Frame Relay with my provider.
Everything worked excellent for exactly one week, whereafter the LEC had a
defect repeater, and the PVC was down for almost two days.
The thing that gets me even more, was that due to my knowledge of Cisco now,
I was 99% sure that the problem was the LEC at the branch office, which I
also told my provider, but even though I asked if they could verify that
real quick so they could call the LEC and hand over the problem, it took
them six and a half hour before they looked at it, and in five minutes, they
confirmed my conclution, but at that time, it was too late before the LEC
was done doing their loopback tests, so it didn't get fixed until the
following morning.
Arrrg!!!
This office is located so bad that not even cable or wireless broadband are
available, so I am kind of stuck with a problem. On the other hand, there's
a limit to how much we want to spend on their WAN, because they're only 4-5
people up there.
Anyway, thanks for your reply, have a great weekend,
Ole

Subject: RE: Following the local loop [7:20685]
Typically the LECs switch will have some sort of trunk to the FR providers
FR switch..
Usually the FR switch will co-locate in the LEC CO...
As for the wire path in your case they could easily be in the same cable
bundle back to the CO...
Even if you got a different LEC for the local loop the cable would most
likely be in the same cable in the same riser (most office buildings only
have 1 telco riser)...
In my experince though most problems seem to happen with CO cross connects
(due to the amount of changes always being made). This always affects (in my
experience) data circuits more so..
So I would have more faith in a POTS backup even if it uses the same cable
back to the CO.
If you really want true diversity you need to ensure:
1) Complete physical seperation at local demarc (seperate cable riser,
seperate telco cable entry)
2) Complete physical seperation on path to CO (no common cable vaults, etc)
3) Complete physical CO for each circuit
et...etc...
It's very expensive and most office buildings do not have the facilities
covered in #1
Hope this helps a bit.....
