Product Line(s)

The Cisco 1-Port Channelized OC-12/STM-4 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.


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. At present, concatenated services at VC-4 rates are available only in some parts of the world (for example, Europe), with higher rates not yet readily available. The new Channelized OC-12/STM-4 SPA provides customers in these areas with an STM-4 POS interface that can be provisioned through the traditional network. The Channelized OC12/STM-4 SPA builds on the SONET/SDH channelization capability.
