Product and Interface Descriptions
Ethernet Interface
The MultiModem wireless modems with an Ethernet interface provide shared Internet access with one IP
address. The built-in routing capabilities provide DHCP services and firewall security using Network Address
Translation. Due to the routing capabilities, these modems are sometimes called routers.
address. The built-in routing capabilities provide DHCP services and firewall security using Network Address
Translation. Due to the routing capabilities, these modems are sometimes called routers.
These modems support "always-on" network connection as well as "dial-on-demand" for Internet services. The
"always-on" network connection automatically establishes a wireless data connection and allows for around the
clock surveillance, monitoring or real-time data acquisition of any remote Ethernet device such as a Web
camera. If the data link is dropped in the event of poor reception or a complete loss of service, it will
automatically re-establish the data link. When configured for "dial-on-demand" the wireless modem only
accesses the Internet when data is present. This configuration is ideal for sharing Internet access among
networked PCs.
