Chapter 1 – Introduction and Product
Description
This User Guide describes the MultiModem® rCell intelligent wireless routers with an Ethernet II interface. The MultiModem
rCell Router is configured for one of three connectivity modes: 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 router to “wake up” and initiate a connection when it detects an incoming ring. For security reasons,
you can setup the router to wake up based on a particular caller ID number. 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 router only accesses the
Internet when data is present. This configuration is ideal for sharing Internet access among networked PCs.
