Cisco SPA-1CHOC3-CE-ATM 1-Port Channelized OC3/STM-1 Port Adapter
Overview
The Cisco 1-port Channelized OC3/STM-1 circuit emulation over packet and ATM 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, and so on) to be deployed on the same interface processor.
The Circuit Emulation over Packet (CEoP) SPAs provide a new service offering. These SPAs provide bit-transparent data transport that is completely protocol independent. For the first time, this allows network administrators to use their existing IP/MPLS network to provide leased-line emulation services or to carry data streams or protocols that do not meet the format requirements of other multiservice platform interfaces. In addition, these SPAs can be used
for low-speed ATM services, including Inverse Multiplexing over ATM (IMA).
Specifications
The Cisco SPA-1CHOC3-CE-ATM 1-Port Channelized OC3/STM-1 Circuit Emulation Over Packet Port Adapter is a network interface module designed for high-end Cisco routing platforms.
Overview: The Cisco SPA-1CHOC3-CE-ATM provides channelized OC3/STM-1 connectivity with circuit emulation capabilities over packet networks. Here are some key points:
-
- Service Flexibility: This SPA allows network administrators to use their existing IP/MPLS network for leased-line emulation services or to carry data streams that don’t conform to other multiservice platform interfaces.
- Protocol Independence: The SPA offers bit-transparent data transport that is completely protocol-independent. It can handle arbitrary bit streams without predefined format requirements.
- CESoPSN and SAToP: The SPA meets emerging standards for Circuit Emulation Services over Packet Switched Network (CESoPSN) and Structure-Agnostic Transport over Packet (SAToP). In SAToP mode, it treats data as an arbitrary bit stream encapsulated in IP/MPLS packets. In CESoPSN mode, it adheres to a defined format.
- Low-Speed ATM Services: The SPA can also be used for low-speed ATM services, including Inverse Multiplexing over ATM (IMA).
Benefits:
-
- Network Scalability: Available on high-end Cisco routing platforms, the SPA offers network scalability with lower initial costs and ease of upgrades.
- Investment Protection: The Cisco SPA/SIP portfolio ensures investment protection by supporting consistent features, broad interface availability, and the latest technology.
- I-Flex Design: The I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs), maximizing connectivity options and offering superior service intelligence while reducing overall cost of ownership.
