Egate-20 Ethernet over T1 or E1 Gateway
Egate-20 is an Ethernet over E1 or T1 gateway. The RAD Egate-20 concentrates and switches Ethernet traffic received from up to eight remote locations connected over eight E1 or T1 circuits, and transmits the traffic to the packet network.
Typical applications include Ethernet VPN services over E1 or T1 lines, or aggregation of enterprise LANs over E1 or T1 circuits (see Figure 1).
Using Egate-20, service providers can offer transparent LAN services. VLAN tagging or VLAN stacking allows all user traffic to be transported transparently while keeping all user VLAN settings intact.
When using Egate-20 in conjunction with RAD's RIC and FCD CPEs, service providers can offer a complete LAN access solution.
Optimized for Ethernet over PDH access, Egate-20 reduces equipment costs and simplifies network maintenance. Egate-20 allows up to three 10/100BaseT ports to be used for connecting the service provider to the packet switched network (PSN), and eight E1 (balanced/unbalanced) or T1 ports for connecting the remote
subscribers to the service provider. Traffic can be classified into three priority queues according to VLAN priority (802.1), DSCP and physical port. Higher priority can be assigned to real-time applications, such as voice and video.
The RAD Egate-20 can be managed using different ports and applications:
- Local out-of-band management via an ASCII terminal connected to the RS-232 port
- Remote out-of-band management via the dedicated 10/100BaseT port
- Remote inband management via the Fast Ethernet or TDM ports.
- Remote management is performed using Telnet, Web browser or RADview Lite, RAD's
- SNMP-based element management system.
Management traffic and user Ethernet traffic are transported together on the same Ethernet
stream on the E-Gate-20, separated by different VLANs, ensuring management security.
