Enfora Enabler III-G Modem Integration Guide For a minimal implementation, connect RxData and TxData to the COM port serial data lines, connect DTR and RTS to GND. Ring Ring Ring 6.6.10.1. Ring Indicate (Pin 23) The Enabler III-G 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 100-pin I/O signal connector. 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. Every 3 seconds the ring string is generated and sent over the Receive (Data Out) (Rx) line. If there is a call in progress and call waiting is activated for a connected handset or hands free device, the Ring pin switches to ground in order to generate acoustic signals that indicate the waiting call. 1 second 2 seconds 1 second RING String RING String 2 seconds When a Fax or data call is received, Ring goes low and will remain low. Every 3 seconds a ring string is generated and sent over the Receive (Data Out) (Rx) line. 3 seconds RING String RING String 3 seconds RING String When an incoming SMS is received , Ring indicate goes low for 1 second, then returns to a high state.

MCSI – Multi-Channel Serial Interface (Pins 12, 14, 16, 18) Pin Name Pin Number Signal Direction Description MCSI_RX 12 I Serial Data Input MCSI_TX 18 O Serial Data Output MCSI_CLK 14 IO Serial Clock I/O MCSI_FSYNC 16 IO Frame Synchronization I/O The multi-channel serial interface (MCSI) has multi-channel transmission capability. MCSI expand the parallel interface of a MPU or DSP to connect to external devices such as audio codecs and GSM system simulators. The MCSI on the module provides full-duplex communication with master or slave clock control. All transmission parameters are configurable to cover the maximum number of operating conditions: • Master or slave clock control (transmission clock and frame synchronization pulse) • Programmable transmission clock frequency • Single-channel or multi-channel (x16) frame structure • Programmable word length: 3 to 16 bits • Full-duplex transmission • Programmable frame configuration • Continuous or burst transmission • Normal or alternate framing • Normal or inverted frame polarity • Short or long frame pulse • Programmable oversize frame length • Programmable frame length • Programmable interrupt occurrence time (TX and RX) • Error detection with interrupt generation on wrong frame length GSM digital audio interface (DAI) operating modes (radio uplink, radio downlink, and acoustics). The DAI mode is a GSM test interface that is used to determine the routing of speech data for the devices being tested. In DAI mode, the MCSI is configured for direct connection to the GSM system simulator interface, including the reset system simulator (RSS) signal. For hardware reference only. There is no generic firmware to support this function. Firmware must be added to enable MCSI GSM0308PB001 50 Version 1.03– 7/17/2007
