Newbridge E3 ATM UNI/NNI interface card
Newbridge Networks was a Canadian networking equipment vendor, based in Kanata, Ontario, and one of the major independent suppliers of ATM and frame relay wide-area switching and access hardware through the 1990s. Alcatel acquired Newbridge Networks in 2000, in a deal valued at roughly US$7.1 billion, folding its ATM and access product lines into Alcatel's data networking business; the Newbridge brand itself did not continue as a standalone line after integration. The single item on this page is genuine legacy Newbridge-branded ATM access hardware.

Where a destination does not admit used network equipment please tell us before we quote. Hardware only, and given the age of this platform, ongoing vendor software support should not be assumed. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.

Questions
Frequently asked questions
Is Newbridge Networks still in business?
No. Alcatel acquired Newbridge Networks in 2000 for approximately US$7.1 billion and absorbed its product lines into Alcatel's own data networking division; the Newbridge brand was retired.
What does UNI/NNI mean on this card?
UNI (User-Network Interface) is the connection type used between an ATM end-system and the switch; NNI (Network-Network Interface) is used between switches. This card supports both modes over a 2-port E3 interface.
