WAN Backhaul Configuration
Profile Interface Configuration
A Wireless Wide Area Network (WWAN) card is a specialized network interface card that allows a
network device to connect, transmit and receive data over a Cellular Wide Area Network. The
Brocade Mobility 7131 Access PointN model access point has a PCI Express card slot that supports
3G WWAN cards. The WWAN card uses point to point protocol (PPP) to connect to the Internet
Service Provider (ISP) and gain access to the Internet. PPP is the protocol used for establishing
internet links over dial-up modems, DSL connections, and many other types of point-to-point
communications. PPP packages your system’s TCP/IP packets and forwards them to the serial
device where they can be put on the network. PPP is a full-duplex protocol that can be used on
various physical media, including twisted pair or fiber optic lines or satellite transmission. It uses a
variation of High Speed Data Link Control (HDLC) for packet encapsulation.
The following 3G cards are supported:
• Verizon V740
• Verizon PC770
• Sprint C777
• Novatel Merlin XU870
• Sierra Aircard 880E
• Telstra Elite Mobile Broadband
• Option GT Ultra Express
• Vodaphone Mobile Connect E3730
• Aircard 503
• Aircard 504 / AT & T 890
