Cisco A900-IMA16D= Netzwerk-Switch-Modul

Cisco ASR 900 Series Ethernet interface modules are designed to give customers a high degree of 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 900 Series Aggregation Services Routers achieve outstanding results when deploying IEEE 1588-2008 protocols for frequency and phase synchronization. Not all customers will deploy IEEE 1588-2008 for synchronization; therefore, the Ethernet interface modules also support input and output frequency synchronization using synchronous Ethernet (SyncE).<br><br>All Cisco ASR 900 Series Ethernet interface modules support online insertion and removal (OIR), which contributes to a higher uptime for the Cisco ASR 900 Series routers.
