Cisco SPA-1XCHSTM1/OC3 1-Port Channelized STM-1/OC-3c to DS-0 SPA Port Adapter:

Purpose and Connectivity:

• • The SPA-1XCHSTM1/OC3 is designed for circuit emulation over packet (CEoP) and ATM services.
  • It provides a single channelized STM-1/OC-3c port for versatile connectivity.
  • This port can be configured with multiple channels of n x DS-0 in a SONET environment or n x E1, E1, fractional E1, or 64 kbps in an SDH environment.

Features:

• • Jitter and Wander Compliance: The adapter adheres to ITU G.823/824 standards for traffic interfaces.
  • I-Flex Design: Leveraging shared port adapters (SPAs) and SPA interface processors (SIPs), it prioritizes voice, video, and data services. The I-Flex design enhances connectivity options and offers programmable interface processors for line-rate performance.
  • CESoPSN and SAToP Support: The SPA meets emerging standards for Circuit Emulation Services over Packet Switched Network (CESoPSN) and Structure-Agnostic Transport over Packet (SAToP) transport.
  • Flexible Deployment: Different interfaces (such as Packet over SONET/SDH, ATM, Ethernet) can be deployed on the same interface processor.

Applications:

• • Mobile Networks: It transports 2G and 3G network traffic over packet networks for mobile operators.
  • Leased-Line Emulation: Network administrators can use existing IP/MPLS networks to provide leased-line emulation services.
  • Low-Speed ATM Services: The SPA supports low-speed ATM services, including Inverse Multiplexing for ATM (IMA).
