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.
