OptiSwitch 910-M

Circuit Emulation Services

The OS910-M chassis is positioned for the Metro Ethernet access networks and for the cellular 2G/3G packet backhauling enforced with CES technology. The incorporated CES technology enables convergence of traditional E1/T1 services over single cost-effective Metro Ethernet network.

The OS910-M multi-service solution is a small form factor (1RU), high-performance chassis offers wide range of modules for CES and intelligent packet services with industry-leading performance and advanced feature integration. The product provides high availability based on redundant and hot-swappable elements to insure maximum uptime for mission-critical Telco services.

CES Modules Description The EM9-CES modules enable Circuit Emulation Services (CES) functionality transporting 1or 4 full 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 packet-switched network environments characterized by packet loss, jitter, packet misorder, link disconnects and reroutes.
