GM47/48 Technical descriptionBA/SEM/MS 02:0004 Rev B20ATMS and AFMS are the audio input and output for the module. Theanalogue audio signals can be used in two different modes, Normaland Portable Handsfree.HandsfreeThis mode is referred to as Audio To Mobile Station (ATMS) andAudio From Mobile Station (AFMS). It is used by audio accessoriessuch as Handsets and Handsfree equipment.Portable HandsfreeThis mode activates a different amplification factor in the MobileEquipment (ME). It also activates a microphone bias level in ATMS.This is the default mode.3.6.1 Audio To Mobile Station (ATMS)ATMS is the analogue audio input to the module. It connects to theaudio input of the CODEC in the module. The CODEC then convertsthe analogue audio to digital audio, in PCM format, which isconnected to the internal PCM bus in the module. The internal PCMbus connects the encoded audio to PCMO on the system connector.ATMS is also used as the microphone input from the PortableHandsfree. If this is the case, a DC bias is provided from the ATMS.All sources must be AC-coupled except the Portable HandsFreemicrophone, which shall be DC-coupled in order to supply DC currentto the Portable HandsFree microphone. AC coupling preventsincorrect biasing or damage of the ATMS input. The capacitor musthave a value greater than shown below to avoid attenuation of lowfrequencies.The ATMS input is a passive network followed by the transmit part ofthe CODEC.Parameter LimitApplication driving impedance (0.3 - 3.5 kHz) < 300 ΩAC coupling capacitance 3> 1 µFModule input impedance (0.3 - 3.5 kHz) >50ΚΩLow frequency cut-off (- 3 dB) 300 Hz ± 50 HzHigh frequency cut-off (- 3 dB) > 3500 HzMaximum allowed input level 1.5Vpp = 530mVOutput DC bias level Handsfree mode 0 V 3 AC coupling capacitance must be supplied by the application, unless a DC coupled microphoneis used.

DSR signal has been removedas it is usually connected to DTR in most systems.The signal levels do not match the standard RS-232 (V.28) levels. Therelationship between the levels is shown in the table belowRS - 232 Level RD, TD RTS, CTS, DTR, DCD, RI 2.75 V CMOS Level< - 3 V 1OFF > 1.93> + 3 V 0ON < 0.80 VConversion between the 2.75V CMOS levels and the RS232 levelscan be achieved using a standard interface IC, such as the MaximIntegrated Products MAX3237.3.10.2 Serial Data Signals - RD, TDThe default baud rate is 9.6 kbit/s, however higher bit rates up to 460kbit/s shall be supported, and set by an AT command.
