62 Passport 7400 Multiservice Switch
PP7400 Key Features Benefits
System Networking Redundancy Redundancy available at CP, FP, system bus, Fan
Unit & Power supply to avoid single point failure
Multiple Priority System Allocates bandwidth dynamically, reducing
traffic congestion and delivering the least possible
network latency, guaranteeing service level for
all traffic
ATM SVC/PNNI/IISP Support Provides ease of configuration and management
with reduced latency for voice and improved
connectivity for LAN traffic
Next Generation ATM Dedicated ASIC to optimise IP performance
IP module over ATM
Frame Relay RFC 1490 WAN PVC over Provides seamless inter-working between Passport
Frame Relay protocol 7400 and routers
QoS-enabled for Frame Support QoS prioritisation(TP) for FR circuits over
Relay service PP network
Voice Toll-quality Voice Support single-hop SVC for voice connection to
(Clearvoice) deliver toll-quality voice at G.729
FAX Demodulation Efficient consolidation of fax with other services
reduces communication costs. Transmits faxes
with only 9.6/14.4 Kbps instead of 64 Kbps
A-law and Mu-law Inherently provides signalling conversion and
conversion avoids the need for external signalling equipment
Echo Cancellation On-board echo cancellation with 64ms tail delay
delivers superior voice quality and eliminates the
need for external devices
Support for both AAL2 channel multiplexing for greater networking
VoATM and VoIP efficiency
LAN Routing Support: RIP, Provides flexibility in building IP networks
RIPv2, OSPF, BGP-4, EGP
Scalability 32 Port MSA FP A flexible card that supports a mix of services
(ATM, frame relay, CES, IP) and greatly enhances
the customer's ability to adapt to growth in
different services without having to deploy
separate FPs and incur incremental costs to spare
multiple FPs
4 Port MVPe A four port version of the existing 1 Port MVPe
which provides significant port density and cost
improvements
MPLS Support for evolving MPLS standards to deliver
significant traffic handling improvements in
multiservice IP-based networks
