Converting BRI to PRI for Remote Access ServersExecutive OverviewIn many parts of the country, a PRI circuit is more expensive than multiple BRI circuits. For example, a PRI circuit may cost $2,100 per month, and a single line BRI may cost $50 per month. Twelve BRI lines provide the equivalent capacity for only $600 a month. Many Internet Service Providers (ISPs) use remote access concentrators with an integral PRI. ATLAS 800 can front-end the concentrator and convert multiple BRI lines to PRI, saving customers significant recurring monthly costs.
ATLAS SolutionThe 12 BRI lines provide 24 BRI channels that will be switched and converted into the PRI interface for the Remote Access Server (RAS). The PRI between ATLAS and the RAS will support 23 simultaneous BRI channels. The ATLAS Octal BRI module includes:
