Cellular Voice only Adapter

The Model 1801-080 is a voice only cellular device and is designed to operate on non-pc programmable systems. This device provides voice communication only and can be used when POTS lines become unreliable or they become impractical to install because of related cost (trenching, long wire runs, etc.). Programming or data transfer is not possible with the voice only device. This also includes modem programming (modem to modem communication is not possible over a cellular network).
