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. The Ethernet gateway aggregates and switches Ethernet traffic into eight Deployed at a central location channelized E1 or T1 circuits, each (see Figure 1), Egate-20 aggregates user supporting up to 248 or 192 Ethernet Ethernet traffic received from remote channels (248 over E1 or 192 over T1). devices, such as RAD’s RICi-E1/T1, FCD, The traffic is combined into channelized and ASMi, thus completing a full access E1 or T1 streams, and handed over to the solution from the service provider central PSN via the unit's Fast 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.

SDH/SONET environment, service providers network, and users connected to the TDM achieve seamless interconnection between MANAGEMENT network. Virtual channels are established customers utilizing different networks Egate-20 can be managed using different between the far-end users by tagging (TDM and packet-based), while ports and applications: separate user traffic channels with VLANs maintaining the same service level (B, C and D). These virtual channels • Local out-of-band management via an attributes. transparently forward all user traffic.
