CISCO SYSTEMS Cisco Asr 900 8port Sfp Gigabit Ethernet Interface Module Spare
The Cisco ASR 900 Ethernet interface modules are designed to give customers flexibility and value. All Ethernet interface modules share a common core that supports time-stamping on the module for Y.1731 operations, administration, and maintenance (OAM) delay measurement functions, to achieve precise results for one-way and two-way delay measurement. The modules also provide time-stamping functions for the IEEE 1588-2008 protocol. These time stamps help ensure that the Cisco ASR 903 Router achieves outstanding results when deploying IEEE 1588-2008 protocols for frequency and phase synchronization. Not all customers will deploy IEEE 1588-2008 for synchronization, so the Ethernet interface modules also support input and output frequency synchronization using synchronous Ethernet (SyncE).
