Integration Guide Version 0.03 6.8 Control Connector Signal Descriptions and Functions 6.8.1 Input Power The Enfora Enabler II-E module uses a single voltage source of VCC=+3.3V to 4.5V. (exact values of the uplink currents are shown in Tables 5.3.1 GSM Operating Power and 5.3.2 GPRS Operating Power). The VCC lines (pins 1 to 6) should be connected on the application board. ! The uplink burst will cause strong ripple on the voltage lines and should be effectively filtered.
Integration Guide Version 0.03 6.8.2 Ring Indicate The Enabler II-E module is capable of using the Ring line to discern the type of incoming call. The indicator can be monitored via a hardware line available on the 60 pin I/O signal connector. The Ring Indicator pin is #49. The function of the Ring line depends on the type of the call received. When the module is receiving a voice call, the Ring line goes low for 1 second and high for another 2 seconds.
