Clock synchronization - adaptive, internal/external & loopback OS910-M leverages resiliency, OAM, QoS & Multi-Service capabilities over Metro Ethernet IP/MPLS transport CES Modules Description The EM9-CES modules enable Circuit Emulation Services (CES) functionality transporting structured or unstructured E1/T1 circuits over an Ethernet/IP/MPLS networks. The modules comply with IETF PWE3 SAToP and CESoPSN industry standards, as well as with the Metro Ethernet Forum’s MEF-8 specifications. The modules perform emulation of T1 or E1 synchronous circuits by incorporating TDM bitstreams into packets and transmitting them over packet-switched networks as streams of packets. These streams are referred to as pseudo-wires (PW) or Ethernet Virtual Circuits (EVC) (tagged with VLAN or MPLS labeled) and marked with real-time priority for strict priority forwarding and minimal latency, jitter & packet loss. A pseudo-wire can transport a full TDM circuit or a bundle of time slots from a TDM structured circuit. The modules’ synchronization over packet performance meets G.823/G.824 jitter and wanders requirements, impaired packetswitched network environments characterized by packet loss, jitter, packet misorder, link disconnects and reroutes.

Architecture With its design based on state-of-the-art wire-speed technology, the OS910-M offers a futureproof solution for Wireless operators, ILECs, IXCs, MSOs or green-field service providers, fitting various business subscriber SLAs. A single OS910-M, serving as a Multi-Service device, can facilitate the provisioning of revenue generating new value-added services thanks to its wide spectrum of service features. VPN Services & Protection Compliant to MEF Ethernet Virtual Circuit (EVC), the OS910-M can offer three types of VPNs for emulated circuit services: 1. Layer 1 Optical VPN – a cross-connect mode with transparent mode (no MAC learning) 2. Layer 2 VPN – VLAN-based tunneling Q-in-Q stacking, swapping or mapping services 3. Layer 2.5 VPN – a label-based MPLS VC for a pseudo-wire PWE3 or H-VPLS MTU-s All the above VPN services can be fully protected using port redundancy, dual-homing, and/or ring topology with a recovery time of less than 50 ms. In addition to L2 VPN, the OS910-M can offer integrated IP router services to save the costs of an external router and provides a single demarcation platform for managed L2 VPN and IP services. Traffic Management The OS910-M enables a value-added network infrastructure, with end-to-end per flow QoS. It supports full CoS and QoS (MEF 14 model) including flows classification, rate limiting, shaping, WFQ scheduling, and strict priority for lower delay/ jitter and guaranteed throughput in real-time applications. In addition, it enables dynamic/adaptive buffer pools to prevent bursty traffic starvation and ensure queuing resources effectiveness. For network convergence applications that have a clear boundary between customer’s and carrier’s networks, CoS layers (802.1p, IP ToS & MPLS EXP bits) can be mapped/marked to preserve priorities or map them into predefined protection profiles set by the carrier. Hierarchical QoS – CoS-Aware rate limit Defining premium SLAs is a key fundamental for service differentiation. The OS910-M enables traffic management based on innovative CoS-aware rate limit to dynamically reuse bandwidth profiles. Dynamic QoS is an important feature that allows for sharing defined rate limited flows with aggregate profile applied to a user network interface or an Ethernet Virtual Circuit. In the new service offering, the consolidated real-time, high-priority and best effort data require different rates and marked class of service. Dynamic QoS helps to share/borrow the bandwidth that was allocated for real-time or high priority applications at a time when these services are not active. Such an offering contributes to a more efficient way of provisioning bandwidth at the access/demarcation of the network without complex configuration sets at the aggregation layer. Denial of Service (DoS) protection The OS910-M incorporates multilayer DoS protection at the hardware architecture on the CPU control plane and data-switching plane. The multilayer control protects the service and the device functionality from hostile traffic without degradation of service performance or affecting of the forwarding database or CPU availability. Multiple traffic types can be policed or discarded starting from frame level such as broadcast, multicast up to IP/TCP/UDP layers. Management - OAM The OS910-M control plane incorporates a list of highly manageable feature that offers ensured interaction with carrier’s OSS and NMS platforms, based on industry standard Southbound out-of-band or in-band interfaces. In addition, it can be managed via MRV’s MegaVision-Pro NMS to have complete GUI and Northbound gateway (XML, TL1 & SNMP) of an entire map of clustered devices for configuration, performance analysis, and inventory control. For the service providers, the OAM that is provided by a demarcation device determines to a significant extent the metrics that can be used to establish the SLA with a business subscriber. The OS910-M incorporates enhanced standards compliant MEF OAM and gives the service provider the ability to monitor the network and provision services, and promptly determine the location of faults remotely from the network operation center. Ethernet OAM with IEEE802.1ag & ITU-T Y.1731 The connectivity of Ethernet bridge devices across Metro Ethernet or other transport networks creates dedicated or virtual Ethernet circuits. An endto-end service architecture requires administrative domain hierarchy with corresponding OAM enabled titles. The OS910-M incorporates connectivity, discovery and fault management along performance statistics of delay, jitter and frame loss for demarcation and intermediate points of service. Ethernet loopbacks The OS910-M offers remote loopback functionality on a physical interface or a specific VLAN that traverses UNI or NNI interfaces. The loopback function allows for the troubleshooting of the service, remotely, from NOC, or any other manageable location without needing to actually visit the customer premises. Loopback functionality performed in hardware level for performance monitoring and SLA verification in wire-speed. Copper TDR The OS910-M incorporates copper TDR that can identify problems with CAT5 copper cables on a customer’s site such as opens, shorts and wrong impedance. Optical Performance Level Monitoring (Digital Diagnostics) The OS910-M supports the SFP Digital Diagnostics standard (as per SFF-8472). A powerful OPM tool, it provides access to a number of real-time SFP operating parameters such as optical TX/RX power, voltage and temperature, as well as component information such as vendor code, serial number and wavelength. The information provided by Digital Diagnostics, together with alarm and warning thresholds, enables a network administrator to identify potential problems in optical transmission and take preemptive action before any service outage actually occurs. Per-service performance monitoring The OS910-M offers real-time and historical reporting on various service performance metrics, including port/VPN-EVC utilization, transmission errors, and QoS threshold exceptions. Each service can be tracked for statistical information to help in base lining and troubleshooting traversing services. This service enables users to verify service guarantees, increase network reliability by validating network performance. Performance monitoring uses pro-active monitoring to generate traffic in a continuous, reliable, and predictable manner, thus enabling the measurement of network performance and health. Link Fault Reflection/Propagation The link fault reflection propagates the fault from network interface to user interface. Such functionality is configurable and operated on LOS fault that will trigger the user link to down mode. In scenario of network interfaces protection, the fault propagation will be triggered only after the LOS of both network interfaces. Sniffer VLAN The OS910-M incorporates a powerful tool called Sniffer VLAN. This feature enables the operator to configure a dedicated sniffer VLAN to remote surveillance center for remote analyzer. Sniffing on the OS910-M can be set per specific customers’ VLAN, per L2-3-4 fields or per learn table MAC. The remote service monitoring inline with interception processes based on requirements of Law Enforcement Monitoring.
