Overview

The Cisco®Interface Flexibility (I-Flex) design combines shared port adapters (SPAs) and SPA interface processors (SIPs), taking advantage of an extensible design that helps enable service prioritization for voice, video, and data services. Enterprise and Service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The Cisco I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. Cisco I-Flex enhances speed-to-service revenue and provides a rich set of quality of service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications for the Cisco 2-Port Gigabit Synchronous Ethernet Shared Port Adapter

Specifications

Cisco SPA-2X1GE-SYNCE 2-Port Gigabit Synchronous Ethernet Shared Port Adapter (SPA). Here are the key details:

Purpose and Connectivity:

• • The SPA-2X1GE-SYNCE is designed for circuit emulation over packet (CEoP) and ATM services.
  • It provides two channelized Gigabit Ethernet ports for versatile connectivity.
  • These ports can be used for bit-transparent data transport, making them protocol-independent and suitable for various applications.

Features:

• • Jitter and Wander Compliance: The adapter adheres to ITU-T standards such as G.8261, G.8262, G.8264, and G.781, ensuring precise timing and synchronization.
  • Synchronous Ethernet (SyncE): Utilizes the PHY Ethernet layer to transmit frequency to remote sites. SyncE provides one-to-one parity with SONET/SDH networks while leveraging Ethernet advantages.
  • IEEE Standard 1588-2008 (PTPv2): Designed for precise timing and synchronization over packet-based infrastructures. PTP uses packet communication to synchronize IEEE 1588-2008 clocks.
  • Applications: Service providers use this SPA to efficiently deliver timing to cell sites, base stations, access equipment, and aggregation devices in their networks. It’s particularly useful for synchronous Ethernet within Metro Ethernet networks and migration to all-packet architectures.
