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.
