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.

Ordering notes

Give the exact part number. This is long-discontinued legacy hardware, supplied refurbished/used, condition confirmed per enquiry. 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.
