Egate-2000
Next-generation Ethernet aggregator over PDH and SDH/SONET
- Grooming and transporting PDH and SDH/SONET traffic over Gigabit Ethernet
- Fully redundant, carrier class aggregation device with STM-16/OC-48 and multiple GbE interfaces for service resiliency
- MEF-supported services for Ethernet Private Line (EPL), Ethernet Virtual
- Private Line (EVPL), Ethernet Private LAN (EPLAN) and Ethernet Virtual Private LAN (EVPLAN)
- Enhanced traffic management with multiple priority queues, shapers and hierarchical QoS
- High availability and link resiliency using SDH/SONET and ITU-T G.8032 Ethernet rings
Egate-2000 is a high-capacity aggregator that is typically deployed in a central location to groom multiple Ethernet user traffic streams received from remote devices, such as RAD’s RICi Ethernet NTUs, over channelized STM-16/OC-48 or STM-4/OC-12 links. The aggregated traffic is then transmitted to the PSN over up to eight GbE links.
Egate-2000 is ideal for Ethernet services, IP DSLAM and WiMAX BTS backhaul applications; it leverages widely available PDH/SDH/SONET infrastructure to deliver carrier-class Ethernet services to sites where native Ethernet is not available.
