Router 5000 Family

This section introduces the 3Com

®

Router 5000 and describes how it can

be used in your network. It also describes the different models of

Router 5000, including:

■ 3Com Router 5012 (3C13701)

About the

Router 5000

The 3Com Router 5000 Family is intended for use on enterprise-level

networks. The Router 5000 Family is ideal for use as core routers on small

and medium enterprise networks, or access routers for network branches

on large-sized enterprise networks. The Router 5000 is suitable for

applications on carrier-level networks, such as telecom management

networks and billing networks. The Router 5000 features a modular

design and accepts multiple optional MIMs (Multi-functional Interface

Modules) and SICs (Smart Interface Cards).

The Router 5000 Family uses high-speed microprocessors and 3Com’s

network operation system platform. The router provides simple

configuration, rich network security features, and supports dumb

terminal access, SNA (Systems Network Architecture)/DLSw (Data-Link

Switching), IP multicast, ATM, MPLS and abundant QoS (Quality of

Service) features.

The Router 5000 provide the following features:

High-performance processor The Router 5000 uses

high-performance processors to handle all the integrated interface data,

such as packet processing capacity, maximum traffic on interfaces, delay,

frame drop rate, restoration period due to overloading of the system, and

system reset period.

14 Chapter 1: Introducing the Router 5000 Family

Multiple interface card/interface module options The Router 5000

provides SIC slots and MIM slots for installing expansion modules

including serial interfaces, T1/CT1/PRI interface, E1/CE1/PRI interface, BRI

S/T and U interfaces, Ethernet interface (including FE/GE, electrical

interface and fiber interface), ADSL/G.SHDSL interface, ATM 25M/155M

interface, and so on.

Multiple channels of asynchronous serial interface access The

router can operate as a small Internet access server when connected to

PSTN (Public Switched Telephone Network) via the asynchronous serial

interface. With an analog Modem interface card, the router can be

directly connected to PSTN to serve as a small access server.

Ethernet access solution By extending SICs and MIMs, the

Router 5000 can provide multiple forms of Ethernet interfaces, such as

optical/electrical interface, 10/100/1000Mbps interface. Thereby, the

networking capability of the router can be significantly improved.

Voice capabilities The Router 5000 support multiple voice interface

modules, which can provide such interfaces as FXO/FXS/E&M, E1VI, T1VI.

With high-speed CPU and digital signal processing (DSP) technology, the

Router 5000 can provide voice over IP (VoIP) services with high quality

voice.

xDSL/MPLS features The ADSL/ADSL-I/G.SHDSL module for the

Router 5000 allows the medium-to-small-sized enterprises to access the

Internet over DSLAM equipment via PSTN. MPLS, a combination of IP and

ATM technologies, provides faster forwarding speed, get support from IP

routed protocols, and control protocols, thus satisfying the requirements

that various new applications put on the network.

Data Security Supports ID authentication protocols, including PAP

(Password Authentication Protocol), CHAP (Challenge Handshake

Authentication Protocol), RADIUS (Remote Authentication Dial in User

Service), TACACS+, firewalls, VPN (Virtual Private Network, including

GRE, L2TP), provides IPSec (IP Security), IKE (Internet Key Exchange)

technologies, and backup solutions.

Online software upgrade The onboard Flash memory allows you to

upgrade the software online, add new features, and extend new

functions.
