I am looking at adding a couple of additional shots to an existing 15 GHz system. It will be point to point links. Hot standby. Public Safety grade of equipment. I expect that I will require a minimum of a single T1, but expect that I will actually need capacity for four T1's per link.
Any sugestion for proven equipment. This will be a system that I will be quoting for resale, and must provide on-going service for it.
Thanks.

Harris Truepoint 5000
Have a look at this:
http://www.harrisstratex.com/products/a ... nt/tr5000/
We have lots of these! You can put in combo cards with DS1 or Ethernet interfaces. Good SNMP and web management, as well as traditional contact closures. It has proven reliable.
Good Luck!

If you are going to use Harris Truepoint please keep this in mind.
(to give you an idea of my experience with these radios, I work for Rogers Wireless, Canada's Largest Cellular provider and we have started using Harris True Pont. In Alberta alone we are up to about 50 or 60 hops)
If you are going to mount the ODU unit at the top of the tower like Harris says, make sure the weather in your area doesn't drop below about -20 C. We have had a ton of failures in my area (North Eastern Alberta/ Northern Alberta) because of the cold weather.
Next bad thing is if you do have a failure and your radio is mounted on the top of a tower you now need to hire riggers to start playing with m/w. Mind you, they are pretty much plug and play, but there are some things a tech needs to be aware of when chaging the radios.
My only advise to you, should you choose Harris. MOUNT THE IDU(indoor unit) AND ODU(outdoor unit) INSIDE YOUR SHELTER AND RUN YOUR WAVEGUIDE UP THE TOWER. This may mean you have to use a higher gain dish to compinsate for the line loss, but well worth it.
This is what we are doing with Rogers because of the problems we are having with cold weather.
As far as the Alcatel comment, we have tons of that m/w too and I don't have anything bad to say about them. Few points on the 8000 I don't like but I prefer Alcatel over Harris. Just my personal opinion, which is open to discussion.

Too funny. We've got a Harris Truepoint OC-3 corridor deployed where the temperature rarely gets above -20C. So far no problems.
You must not have a lot of the Alcatel 8000's? Right now we're going through a big crystal oscillator swapout due to manufacturing defects.
It would be nice to mount the Harris units indoors but the cost savings is too much for engineering to consider it. Getting riggers to swapout parts doesn't figure into their budget, just the initial install and FSJ-2 is cheaper then elliptical.

Actutally we have a lot of 8000's. Has Alcatel released something that reports problems with the LO sub-boards? Or are you just seeing high failure rate.
Strage that your OC-3 is running as well as it is, we are having problems with ours on our Grade Prairie Corridor. Are you doing something different with the installs? Do you mind if I ask who your riggers are?

Alcatel is swapping out all Rev 1 xtal boards due to a high failure rate in the crystals. We've had so many fail that a lot have already been fixed when in for repair. Any remaining are now being swapped out.
I doubt we're doing anything different rigging wise.
We use a variety of companies that are based in Ontario.
