Multi-Tech Systems, Inc. MultiModem rCell User Guide 5
Chapter 1 – Introduction and Product
Description
This User Guide describes the MultiModem® rCell Intelligent Wireless Router with an Ethernet 2 interface. The MultiModem rCell
Router 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
realtime 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.
The MultiModem rCell routers are available in two models:
