Passport 8250 functions
The Passport 8250 is an Integrated Access MUX, a rugged, high-density unit that provides a seamless bridge between traditional voice networks and ATM networks. The Passport 8250 multiplexes TDM traffic - voice, video, IP, frame relay, X.25, and SNA - on DS-1/E1 trunks to OC-3c/STM-1 fiber trunks (ATM over SONET/SDH). Using ATM Forum AAL1 circuit emulation standards, traditional voice network traffic (dial-up Internet access, modem data traffic, telephony, and more) is seamlessly transported over the efficient, high-bandwidth ATM network. Deployed at either the service provider setting or customer premises (campus, apartment building, or office center, for example), the high-density unit supports up to 48 DS-1/E1 ports, up to 336 DS-1s/E1s in a single frame.
See “Passport 8250 device” (page 16) for an illustration of the Passport 8250.
