Re: Anyone familiar with the SBC product lingo?

you'll never get better redundancy than having more than one carrier.

On the contrary, you get better redundancy by sticking to one carrier and making sure that they really provide separacy though the entire span of the circuit. If you have two carriers running fibre to yoiur building down the same conduit, then you do NOT have separacy and as a result, the redundancy is not there. Of course, you can get separacy with two carriers but it is generally more work to verify that the two companies do not share fibre or conduit or tunnels. --Michael Dillon
