Data Sheet Egate-20 Channelized Ethernet Gateway Flexible Ethernet aggregation of Fast Ethernet to eight fully channelized E1 or T1 circuits • Transparent Ethernet services in point-to-point and point-to-multipoint topologies by utilizing VLAN tagging, stacking and switching • Efficient utilization of WAN interface at wire-speed Up to 248 or 192 • Equipment and maintenance costs lower than other alternatives • Four-level QoS according to 802.1p, DSCP, IP Precedence and per port remote LANs over fractional E1 or T1 Egate-20 is a channelized Ethernet Together with service scalability, small gateway for interconnecting PDH and footprint, and low power consumption, channels packet-based networks. Egate-20 significantly reduces equipment cost and simplifies network operation. Egate-20 aggregates and switches Ethernet traffic into eight channelized E1 Egate-20 is typically deployed at a central or T1 circuits, each supporting up to 248 location (see Figure 1), aggregating user or 192 Ethernet channels (248 over E1 or Ethernet traffic received from remote 192 over T1). The traffic is combined into devices, such as RAD’s RICi-E1/T1, FCD, channelized E1 or T1 streams, and handed and ASMi, thus completing a full access over to the PSN via the unit's Fast solution from the service provider central Ethernet ports. site to the customer premises. Egate-20 replaces current high-priced Typical applications include: solutions, such as channelized n × E1/T1 • Ethernet private E-line/E-LAN services routers or multibox solutions based on • Aggregation of Ethernet traffic over cross-connects and switches.
