Access Routers
IRXTM, Firewall IRX, and Office Routers

Connecting your world

Stacked Routers

A family of robust, reliable, full-featured access routers with built-in firewall security For many companies, data networks have become the lifeblood of their business. As such, they require connectivity, security, and reliability.

Lucent Technologies understands. We offer a family of robust, reliable, full-featured access routers with built-in firewall security. Our access routers deliver exceptionally dependable, high-performance connectivity for branch office Local Area Network (LAN)-to-LAN communications and secure Internet access. All Lucent routers share the same advanced ComOS® operating system as our PortMaster® access concentrator -- the servers that more than 2,000 Internet Service Providers (ISPs) and thousands of corporate networks rely on for mission-critical connectivity.

Our experience and technology mean you can count on Lucent for remote network products, whether you're sending voice, data or video around the corner or around the world.

Lucent routers offer the features and performance you need

Our Office, IRX and FireWall IRX routers provide a unique combination of flexibility, reliability, and security. As a result, they can handle virtually any network application, including yours.


Despite their modest cost, Lucent products provide the features and flexibility you require in an access router, such as optimized-routing for every widely used protocol, exceptionally fast data compression, an array of remote management capabilities, and support for a full range of security protocols.


Our routers feature the same ComOS technology that has earned the PortMaster access concentrator a reputation for reliable performance under continuous use. With durable steel casing and a built-in auto-sensing power supply, they offer industrial strength reliability you can depend on 24 hours a day, 365 days a year.


All Lucent products have multi-level authentication and sophisticated firewall packet filtering built in -- at no extra cost.

Branch Office LAN-to-LAN Access
Lucent routers provide efficient, reliable LAN-to-LAN connectivity from remote offices to the main corporate network.

Branch Office LAN-to-LAN

The ideal solution for branch office and Internet connectivity

Optimized edge routing

  • Support for Routing Information Protocol (RIP), advanced Open Shortest Path First (OSPF), and Border Gateway Protocol (BGP) routing, for building complex networks more efficiently
  • Multiprotocol Internet Protocol (IP) and Internet Packet Exchange (IPX) support
  • Point to Point Protocol (PPP) and Multilink PPP
  • Bandwidth on demand. Dial-up connections are initiated and terminated as needed, so you only pay for bandwidth actually used
  • Stac data compression for up to four times greater throughput

Comprehensive management

  • Support for Simple Network Management Protocol (SNMP), Telnet, and out-of-band console remote management
  • PmconsoleTM graphical management utility
  • Flash upgrade capability

Versatile Wide Area Network (WAN) access options

  • Analog
  • Integrated Services Digital Network (ISDN) with ST or U (built-in NT1) interface
  • Leased Line
  • Frame Relay
  • Access speeds up to 2.048 Mb/sec

Support for comprehensive multi-level security

  • Authentication via Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), calling line ID, and call back
  • Built-in firewall packet filtering
  • Centralized security administration and accounting through Remote Authentication Dial-In User Service (RADIUS) software and Syslog support
  • Encrypted and RADIUS-authenticated administrative passwords
  • Scalable filter management through ChoiceNetTM software

The Firewall IRX Router

The solution for secure Internet Access

Our Firewall IRX 211 offers you all the performance, management, and security capabilities of our other routers plus a secure, "screened subnet" architecture that delivers bulletproof network protection.

The Firewall IRX comes with two Ethernet ports. The first is for your public Internet-accessible network where Web and FTP servers reside. The second Ethernet port connects to your private, internal enterprise-wide network. This dual-port design allows you to physically isolate and protect it from unwanted traffic or break-ins via the Internet. The Firewall IRX can be used together with other security devices such as proxy servers and software-based firewall servers to create a multi-level security system.

For wide-area connectivity, the Firewall IRX has both a T1/E1 synchronous WAN port and an asynchronous WAN port. The asynchronous port can be used for primary or back-up routing, or for out-of-band management.

The optimal end-to-end solution

Because all these products share the same Internet-proven ComOS software architecture, our access routers provide a superior, optimized solution for linking with a PortMaster access concentrator at a central site or Point of Presence (POP).
