T1 Customer CPE Replacement?

Hello, We're looking for a good replacement for fractional T1 customers with Cisco 1600- & 1700-series routers as their CPE. They are good routers, but the ongoing support costs are an issue, and we need to replace them ASAP. Someone had mentioned several CPE vendors, such as Adtran and Netopia. Are there any others, and does anyone have any pros/cons of what they're familiar with? Thanks, = TC -- Tom Claydon, IT/ATM Network Engineer Dobson Telephone Company phone: (405) 391-8201 cell: (405) 834-0341
