Ethernet Connectivity. The MultiModem GPRS wireless modem
with an Ethernet interface provides shared Internet access
with one IP address. The built-in routing capabilities provide
DHCP services and firewall security utilizing Network
Address Translation. The modem can be configured for one
of three network connections: always-on, wake-up on ring,
or dial-on demand. 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. The wake-up on ring configuration
allows the modem to “wake up” and initiate a connection
when it detects an incoming ring. For security reasons, you
can setup the modem to wake up based on the caller ID. This
configuration is ideal for reducing the costs associated with
the modem being online and available 24/7. 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.
Industry-standard Modem Commands. The MultiModem
GPRS wireless modem provides industry-standard AT-style
commands for ease of integration into your existing software
application.
Network and RF Approved. The MultiModem GPRS wireless
modem is PTCRB certified. In addition, it has successfully
completed worldwide compliance testing for global RF
approval.
Comprehensive Service and Support. The Multi-Tech
commitment to service means we provide a two-year product
warranty and service that includes technical support,
