Thanks (thanks for the those with the off list replies too). I spoke with a Patton engineer, and it looks like the 4520 series can do what I need. http://www.patton.com/products/pe_products.asp?category=52 I sent a note to Verizon indicating they are going to need to think outside their 'product catalog' if they want to keep the project alive.
