Application Note

Using a Sierra Wireless AirLink Raven X

or Raven-E with a Cisco Router

Cisco routers deliver the performance, availability, and reliability required for scaling mission-crit-

ical business applications in the most demanding enterprise environments.

• Network Management

Many Cisco routers are designed to support a modular platform with a broad range of interface

options and up to 112 10/100 Mbps switch ports with optional Power over Ethernet (PoE), for

providing DC power to network devices such as IP phones. Additionally, support for wireless

LAN standards 802.11a/b/g and support for a Small Form-Factor Pluggable (SFP) port for

Gigabit Ethernet is also built into many of the router models.

• Internet or WAN Connectivity

Cisco routers have up to two 10/100/1000 Mbps built-in routed ports which can be configured

to connect to an outside network, either the Internet or a WAN.

• Security

The Cisco routers have built-in security and up to 2500 VPN tunnels. Cisco Router and Security

Device Manager (SDM) offers simplified management.

• VOIP

Cisco CallManager Express call-processing supports up to 240 Cisco IP phone users. Cisco Sur-

vivable Remote Site Telephony (SRST) offers support for up to 720 Cisco IP phone users,

allowing the router to provide call-processing functionality to keep voice service in operation

should the connection to Cisco CME be lost.

The Sierra Wireless Airlink Raven X and Raven-E provide a cellular solution for primary or

backup connectivity providing an unparalleled flexibility of location. The rugged design of AirLink

modems makes them practical for any location, including industrial installations.
