Datasheet Datasheet OptiSwitch® 904-MBH - 4 / 904-MBH - 4A Mobile Backhaul Ethernet Solution with Circuit Emulation Services (CeS) Support Product highlights OS904-MBH-4 / 4A Overview The OS904-MBH-4 is a compact Carrier Ethernet cell-site demarcation device that supports both Circuit Emulation Services (CES) as well as clock synchronization over packet switched networks (PSN). As part of the MBH (Mobile Backhaul) series of products, the OS904-MBH-4 enable cellular operators to migrate their legacy TDM based network to packet-switched network (PSN) while maintaining the traditional TDM-quality synchronization of their cellular base transceiver stations (BTS). As a CeS supporting device, the OS904-MBH-4 enables the transmission of E1/T1 traffic over PSN using industry accepted standards (CESoPSN, SAToP and MEF 8). In addition, to the well known Adaptive Clock CeS mechanism the solution can function as an Ethernet Equipment Clock (EEC) in a Synchronized Ethernet domain and improve its clocking accuracy by locking to superior network clocks such as Primary Reference Clock (PRC) or SDH Equipment Clock (SEC). To maintain the ITU G.8264 standard required behavior during holdover period the OS904-MBH-4 is using an incorporated Stratum 3 TCXO oscillator. The device also supports 1588v2 slave functionality* (frequency only) as an alternative synchronization mechanism without replacing current intermediate nodes that do not support SyncE.

High-quality timing synchronization and CES are extremely important in 2G GSM, 2.5G GPRS, 3G UMTS and 4G LTE/WiMAX mobile networks for a successful call signal hand-off between cellular base stations and for transferring structured or unstructured E1/T1 circuits over newly deployed Ethernet devices. As a part of the OptiSwitch®900 series, the OS904-MBH-4 is using the well known Master-OS® software that offers Carrier Ethernet features and enables end-to-end visibility and SLA at each Mobile cell site. All timing synchronization and connectivity services can be monitored remotely via end-to-end Ethernet OAM tools according to IEEE802.1ag CFM, ITU-T Y.1731 PM and RF2544 wire speed throughput analysis. * 1588v2 funtionality is supported in OS904-MBH-4A ** future support Not sure which solution best fits your needs?
