Key Points
Nortel Networks Passport 7400 are scalable
multi-service solution that allows integration of
LAN/WAN services into a single easily managed
solution over leased lines, public/private frame
relay or ATM. Key values include:
• Bandwidth Savings. Achieve bandwidth
savings through dynamic bandwidth allocation,
voice (8K) and data compression, silence
suppression, fax demodulation and optimised
LAN access protocols.
• QoS Optimisation. Passport supports Multiple
Priority System (MPS) to allow dynamic traffic
management based on application characteristic
and QoS priorities.
• Branch Office Consolidation. Passport 7400
provides consolidation for ATM, voice, fax,
video, LAN and data services across a single
network link.
• Scalability. The high density MSA32 FP and
the 4-port MVP FP provide scalable, flexible,
cost-effective multiservice and voice solutions.
Network-wide, Passport 7400 can support
thousands of nodes.
• Support for port speeds from DSO through to
and including STM-1
• Low Cost of Operations. Passport 7400
supports switched virtual circuits, avoiding a
large number of provisioned connections and
dynamically providing the best available
traffic path.
• Capacity. Passport PVG converts conventional
circuit-switched voice traffic to Packet voice for
succession network evolution.
