Общая информация (SPA-2XCHOC12/DS0)
SPA-2XCHOC12/DS0 is the Cisco ASR 9000 Series Shared Port Adapter. This Cisco 2-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.
