Enterprise or carrier networks, providing high
performance branch access. Fully scalable, it is
suitable for remote networks comprising as few as
two nodes to as many as several thousands when
deployed in conjunction with the Passport 6400 or
7400 series.

Typical Applications
Nortel Networks recognises that deploying separate
networks for voice, video and data is a challenging
task. It leads to ineffective bandwidth use,
application inflexibility and added complexity. The
solution is network consolidation over a single
platform. Network consolidation provides cost
savings, improves business communications and
increases efficiency.

branch office traffic over a single network
infrastructure. Voice, fax, video, LAN and other data
services such as Frame Relay, SNA, SDLC, X.25, asynch
and HDLC are carried over a choice of link options to
provide efficient, reliable and easily managed
services for mission-critical applications.
