14Chapter 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.
