Configuring 3G Wireless Modems for WAN Connections

3G refers to the third generation of mobile phone standards and technology based on the International Telecommunication Union (ITU) International Mobile Telecommunications-2000 (IMT-2000) global standard. 3G networks are wide area cellular telephone networks that have evolved to include high-data rate services of up to 3 Mbps. This increased bandwidth makes 3G networks a viable option as primary or backup wide area network (WAN) links for a branch office.

Juniper Networks supports 3G wireless modem cards that you can install into the ExpressCard slot in SRX210 devices. When used in a branch office, the SRX210 device can provide dial-out services to PC users and forward IP traffic through a service provider’s cellular network.

For information about which devices support the features documented in this chapter, see the JUNOS Software Feature Support Reference for SRX Series and J Series Devices.
