Cisco 1-port Channelized OC48 to DS3 SPA
Part Number: SPA-1XCHOC48/DS3=
Product Overview
The Cisco 1-Port Channelized OC-48/STM-16 SPA is available on high-end Cisco routing platforms offering the benefits of network scalability with lower initial costs and ease of upgrades. The Cisco SPA/SIP portfolio continues the Cisco focus on investment protection along with consistent feature support, broad interface availability, and the latest technology. The Cisco SPA/SIP portfolio allows different interfaces (Packet over SONET/SDH [POS], ATM, Ethernet, etc.) to be deployed on the same interface processor.
Applications
Internet traffic continues to grow at an explosive rate – with the number of users doubling each year. This unsurpassed growth is increasing the demand for higher-capacity interfaces from OC-3/STM-1 to OC-48/STM-16. In addition, POS enables efficient transport of IP traffic and uses SONET/SDH concatenated payloads (that is, STS-3c/VC-4, STS-12c/VC-4-4c, or STS-48c/VC-4-16c) to achieve a higher order of statistical multiplexing.
Service providers face the challenge of meeting customer demand by building scalable, feature-rich edge networks that can deliver value-added services such as Multiprotocol Label Switching VPNs (MPLS VPNs); voice, video, and data integration; and tiered service offerings at all interface rates without compromising density or line-rate performance. The Cisco Channelized OC-48/STM-16 SPA channels one OC-48 or STM-16 interface into DS-3, E3, OC-3c, STM-1c, OC-12c, or STM-4c channels and provides an extensive set of service-enabling edge features while performing at line rate simultaneously on all ports.
