3.3. Modem Status Indicator

The front panel of the MP215 has a single green LED indicator. The LED has several functions as outlined in Table 3-1 LED Indications. The LED is flashed when the modem’s receiver has picked up a channel in either AMPS mode or CDPD mode. Note that it does not indicate that the modem is registered on the network, just that a valid channel has been acquired.

3.4. Speaker

The MP215 comes equipped with a speaker connection. The speaker output is particularly useful for Circuit Switched Cellular operation (AMPS) to provide audible connectivity information such as network messages or dial tones and can be an effective debug tool for connectivity problems. The speaker output provides 1/10 watt into an 8-ohm load
