BETA DRAFT —CISCO CONFIDENTIAL
3G Wireless High-Speed WAN Interface Card for Cisco 1800, 2800, and 3800 Series Routers
Restrictions for the Wireless WAN HWIC
4
Cisco IOS Release TBD
• Service availability on the HWIC and certification on the carrier network
Restrictions for the Wireless WAN HWIC
The following restrictions apply to the Cisco Wireless WAN HWICs:
• Data connection can be originated only by the host platform call; the call by the other peer connected
to the cellular network is not supported.
• Throughput—due to the shared nature of wireless communications, the experienced throughput
varies depending on the number of users in a given network.
• Latency—Wireless networks have higher latency compared to other wired networks.
• Coverage in your area, at your site, and in the specific location where the router is placed.
• Congestion on the network.
• Any restrictions that are a part of the terms of service from your carrier.

How to Configure the Wireless WAN HWIC
This section contains the following procedures:
• Configuring NAT Using the Cellular Modem
• Creating and Activating a New CDMA Profile Using OTASP
• Activating a GSM Account
• Configuring DDR
• Asynchronous Line and Reverse Telnet\
Configuring NAT Using the Cellular Modem
Network Address Translation (NAT) operates on a router that is connecting two networks; one of these
networks (designated as the inside network) is addressed with either private or obsolete addresses that
must be converted into legal addresses before it forwards packets to the other network (designated as the
outside network). The translation operates in conjunction with routing, so that NAT can simply be
enabled on a customer-side Internet access router when translation is desired.
