Pin 
Signal 
Name 
 In/Out   Description 
37 
–DSR or 
PIO7 
Data Set Ready (Active Low). –DSR indicates module status to the DTE. –DSR 
OFF (high) indicates that the DTE is to disregard all signals appearing on the 
interchange circuits except Ring Indicator (–RI). It reflects the status of the local data 
set and does not indicate an actual link with any remote data equipment. 
SocketWireless
 
Bluetooth (MTS2BTSMI): PIO7 – User definable I/O pin PIO7. 
Defaults as input. 
38 
–CTS O 
Clear to Send (Active Low). –CTS is controlled by the module to indicate whether or 
not the module is ready to transmit data. –CTS ON indicates to the DTE that signals 
on TXD will be transmitted. –CTS OFF indicates to the DTE that it should not transfer 
data on TXD. 
39 
–DCD O 
Data Carrier Detect (Active Low).  –DCD output is ON (low) when a data 
connection is established and the module is ready to send/receive data. 
40 
–DTR or 
PIO6 
Data Terminal Ready (Active Low). The –DTR input is turned ON (low) when the 
DTE is ready to communicate. –DTR ON prepares the modem to be connected, and, 
once connected, maintains the connection. –DTR OFF places the modem in the 
disconnect state under control of the &Dn and &Qn commands. 
Note: When the –DTR pin is not in use, it should be tied low. 
SocketWireless Bluetooth (MTS2BTSMI): PIO6 – User definable I/O pin PIO6. 
Default: Input. 
41 
GND GND 
Logic Ground
42 
SPK- O 
Wireless GSM/GPRS, CDMA, and EDGE.  Negative analog speaker output. 
43 
SPK+ O 
Wireless GSM/GPRS, CDMA, and EDGE.  Positive analog speaker output. 
56 
–LED FDX 
LED Full Duplex (Active Low). LED Output. During normal operation, this pin lights 
the FDX LED to indicate a full duplex mode.  
57 
–LED ACT 
LED Active (Active Low). LED Output. During normal operation, this pin lights the 
Activity LED when transmitting or receiving. It flashes at a rate of 50ms high and 
50ms low when active.  
58 
–LEDLINK O LED LINK (Active Low). LED Output. During normal operation, this pin lights the 
LINK LED to indicate a good link is detected. 
 
 
Pin 58 LED Mode 
Operating Status 
Off 
SCME is off or run in SLEEP and Alarm modes. 
600 ms ON  / 600ms OFF 
No SIM card inserted or no PIN entered, or network search in progress, or ongoing 
user authentication, or network login in progress. 
75 ms ON / 75 ms OFF / 75 ms ON  
3 s OFF 
Flashing 
One or more GPRS contexts activated. 
 
Indicates GPRS data transfer: When a GPRS transfer is in progress, the LED goes 
on within 1 second after data packets were exchanged. Flash duration is 
approximately 0.5 s. 
ON 
Depending on type of call: 
Voice Call: Connected to remote party. 
Data Call:  Connected to remote party or exchange of parameters while setting up 
or disconnecting a call. 
 
59 
–LEDCOL O 
LED Collision (Active Low). LED Output. During normal operation, this pin lights the 
COL LED to indicate a collision. It flashes at 50ms high and 50ms low when active.  
60 
–LEDSPD O 
LED Speed (Active Low). LED Output. During normal operation, this pin lights the 
SPEED LED to indicate 100Mbps is selected.  
61 
VCC PWR 
DC Input Power. 3.3 V or 5 V DC power, depending upon the build. 
62 
MICV I/O 
Single-Ended Microphone. Single-ended microphone input for dial-up 
SocketModem speakerphone and TAM functions. 
63 
AGND GND 
Analog Ground. Analog ground is tied common with DGND on the SocketModem. 
To minimize potential ground noise issues, connect audio circuit return to AGND. 
64 
SPKR O Speaker. Dual purpose output for call progress signals or speakerphone functions. 
Call Progress signaling on MT5600SMI, MT5656SMI, and MT2456SMI-22 is a 
square wave output that can be optionally connected to a low-cost single-ended 
speaker; e.g., a sounducer or an analog speaker circuit.  
Call progress on the MT5634SMI is an analog output. 
Speakerphone Output on the MT5656SMI is under the control of +FCLASS. This is 
a single-ended analog output. SPKR is tied directly to the CODEC. One side of a 
differential AC output coupled through a 6.8K ohm resistor and capacitor.
