But you don't have to have a PRI to do that. Check out Adtrans ISU512 which takes up to 4BRIs and imuxes them together. That is an extremely effective product, which though I haven't installed it personally, have spoken with several persons who use it. The costs of adding BRIs+port charges is probably lower using an ISU512 to get capacity than going FracT1. -ken --- Ken Lam lam@awod.com Integrated Technical Systems Systems, Networks, and Internet Solutions -- Defining Technology Today "'Plug and Play' was only applicable to the original ATARI(tm)"
