Features
GENERAL
The MSP4000 belongs to a full family of Multi-Service Processors designed to
meet the performance, QoS, and security needs of communications equipment used
within the customer premise.
The MSP4000 is ideal for designing VoIP Gateways for small businesses, professional
telecommuters, and branch offices. The MSP4000 is a highly affordable solution for
up to eight ports of derived voice. This Multi-Service Processor provides a migration path
from legacy IAD voice services using time division multiplexing over T1 services to
next generation voice over broadband services.
The MSP4000 is also designed to meet the performance requirements of firewall
applications and provides an additional Ethernet MAC for a dedicated
DMZ port. An integrated encryption engine enables high-performance VPN
services expected by telecommuters and remote offices.
To reduce time-to-market, PMC-Sierra offers comprehensive support for the
MSP4000, including evaluation boards, software, application engineering
support, training, and documentation that together accelerate the product
development process. In addition, the MSP4000 supports Linux, VxWorks, or
custom operating systems.
