Why does MV need an APPO it just needs a APPO-CB and so does D as far as I can tell. But besides that it looks like a rock solid Plan just make sure you have good Antennas and good line of site and when your done you fine tune the link so that you have as little packetloss as possible. Which shouldn't be a problem withthis configureation and I believe will allow you to expand VERY easily. And its only a one time expense:) instead of those T1's ewwwww telco sucks.

I think it will work. Here is how I would do it.
D------------------W------------NOC-----------MV
aPPO+aPPO-CB aPPO+aPPO-CB aPPO+aPPO aPPO-CB+aPPO

Subject: [smartBridges] Using APPOs to Backhaul Modem Traffic
Hi All
I'm looking at putting up some APPOs to backhaul my modem traffic so I
can
stop paying the phone company $2100 a month. The configuration I have
goes
something like this:
D----W----NOC----MV
It is nine miles between each of these points.
Right now I have a T1 running from D to W where it hooks into a Cisco AS
5248. It then runs from W to NOC where it hooks into another 5248 and
ultimately gets routed out to the Internet. I have another T1 that runs
~
from MV back to NOC configured the same way. Each of these locations is
a
POP for dialup.
In D I have 24 dialup lines. 24 in W, and 24 in MV (I have 48 in MV but
don't use but about 20 at a time....long story :)
So assuming worst case I'd have 48 modems running between W and NOC
simultaneously. Of course I'd want to put up an AP on top of wherever I
put the APPOs so you'd have to add in that traffic. I would expect
within
a year to have at most 30 customers at 256 down/128 up in D and somewhat
smaller number in W since there is DSL there already. That would mean
about 2.6 Mb of dialup traffic between W and NOC (again, if all 24
modems
in both D and W were going at once - unlikely), plus whatever broadband
I'd have running through it.
Do you see any issues with performance if I do this? As I mentioned I
have
T1s now, which are full duplex. The APPO will be half, but can carry
what,
5.5 MB in each direction? - far more than the T1. I'd like to remove the
phone company expense, but want to make sure my customers will be unable
to tell any difference in throughput. Also, I'd like to use APPO as
opposed to 5.8 GHz due to the cost. And, even given some of the recent
issues with APPO, I have found them to be more reliable (IMO) that the
YDI
5.8 radios I was using.
I'd appreciate any thoughts from those more experienced than me on this
(which is probably just about all of you. :)
Thanks
Sam
