Chapter 1 Product Overview
1.1 Introduction
3Com Router 3000 Ethernet Family are Ethernet access routers designed for small office home
office (SOHO) subscribers. They provide an uplink Ethernet interface and four downlink layer 2 (L2)
switched 10/100BASE-T Ethernet interfaces that can be isolated.
The 3Com Router 3000 Ethernet Family support multiple virtual private network (VPN) services,
such as layer 2 tunneling protocol (L2TP) VPN, IP security (IPSec) VPN, generic routing
encapsulation (GRE) VPN, and Huawei dynamic VPN (DVPN). They can provide tunnel
connections to remote users to build VPNs that can be internets, intranets, or access networks.
The series support firewall, AAA (authentication, authorization, accounting), network address
translation (NAT), and quality of service (QoS). Therefore, they can ensure security and guaranteed
services to the private networks constructed on the open Internet.
In the series the 3Com Router 3000 Ethernet Family has a build-in hardware encryption chip, which
can significantly improve encryption performance.
The interfaces that the 3Com Router 3000 Ethernet Family series provide are compliant with the
international standards and can work with the products of other vendors at every layer. The existing
investment of users can thus be protected to the maximum.
