Description
This User Guide describes the MultiModem® rCell, model MTCBA-H-EN2, 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 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.
