TX synchronous data clock for ISDN sync data mode. 12 RCLK O Receive Data Sync Clock. RX synchronous data clock for ISDN sync data mode. 22 MIC+ I Microphone positive input. Refer to Microphone Inputs in Chapter 2. 23 MIC- I Microphone negative input. Refer to Microphone Inputs in Chapter 2. 24 –RESET I Device Reset (with pull-up). The active low –RESET input resets the device logic and returns the configuration of the device to the original factory default values or "stored values" in the NVRAM. –RESET is tied to VCC through a time-constant circuit for “Power-on-Reset” functionality. The SocketModem is ready to accept commands after a fixed amount of time (“X” Time) after power-on or reset. Model Time Constant "X" Time Minimum Reset Pulse* MTSMC-G2 250 ms 6 seconds 100us *The SocketModem device may respond to a shorter reset pulse. Reset Line Interface for the MT5692SMI. The modem’s reset line employs a 10K pull up resistor. If an open collector driver is to be used, run that output to the modem only and use a separate driver for other embedded components. The modem’s reset signal may also be driven by a circuit that both sinks and sources current if desired. It is also important to note that these modems do not require an external reset. They have their own internal reset circuitry and voltage monitor and will function correctly even if the reset input is open. Reset GPRS (MTSMC-G2). This signal is used to force a reset procedure by providing low level during reset of at least 500us. The signal is considered an emergency reset only. A reset procedure is already driven by internal hardware during the power-up sequence. If no external reset is necessary, this input can be left open. If used (emergency reset), it has to be driven by an open collector or an open drain. RESET – A Design Consideration: Allowing the host processor to control the RESET line of the SocketModem provides the benefit of allowing the host to reset the device in the event of a failure to respond normally. Resetting the SocketModem will return it to a known functional state. 25 USB_VBUS I USB Voltage Sense.

Chapter 1 – Universal Socket Connectivity Multi-Tech Systems, Inc. GPRS SocketModem Developer’s Guide (S000521A) 9 Pin Signal Name In/Out Description 33 –RTS I Request to Send (Active Low). –RTS is controlled by the DTE to indicate whether or not the DTE is ready to receive data. –RTS ON (low) indicates that the DTE is ready to receive data from the modem on RXD. –RTS OFF indicates to the SocketModem that it should not transfer data on the RXD. Note: When the –RTS pin is not in use, it should be tied low. 34 –RXD O Received Data. The SocketModem uses the RXD line to send data to the DTE and to send SocketModem responses to the DTE. In command mode, –RXD data presents the SocketModem responses to the DTE. SocketModem responses take priority over incoming data when the two signals are in competition for –RXD. When no data is transmitted, the signal is held in mark condition. 35 –TXD I Transmitted Data. The DTE uses the –TXD line to send data to the SocketModem for transmission or to transmit commands to the SocketModem. The DTE holds this circuit in mark state when no data is being transmitted or during intervals between characters. 36 –RI O RING (Active Low). Incoming ring signal from phone. Ring Indicate. –RI output ON (low) indicates the presence of an ON segment of a ring signal on the telephone line. The modem will not go off-hook when –RI is active; the modem waits for –RI to go inactive before going off-hook. 37 –DSR O Data Set Ready (Active Low). –DSR indicates SocketModem 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. 38 –CTS O Clear to Send (Active Low). –CTS is controlled by the SocketModem to indicate whether or not the SocketModem 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 SocketModem is ready to send/receive data. 40 –DTR I 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. 41 GND GND Logic Ground. 42 SPK- O Negative analog speaker output. 43 SPK+ O Positive analog speaker output. 48 GPIO I/O General Purpose Input/Output.

Design Considerations Noise Suppression Design Considerations Adhere to engineering noise-suppression practices when designing a printed circuit board (PCB) containing the SocketModem. Noise suppression is essential to the proper operation and performance of the modem and surrounding equipment. Any OEM board design that contains a SocketModem should consider both on-board and off-board generated noise that can affect digital signal processing. Both on-board and off-board generated noise that is coupled on-board can affect interface signal levels and quality. Noise in frequency ranges that affect modem performance is of particular concern. On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted off-board is equally important. This type of noise can affect the operation of surrounding equipment. Most local

Chapter 1 – Universal Socket Connectivity Multi-Tech Systems, Inc. GPRS SocketModem Developer’s Guide (S000521A) 11 government agencies have stringent certification requirements that must be met for use in specific environments. Proper PC board layout (component placement, signal routing, trace thickness and geometry, etc.) component selection (composition, value, and tolerance), interface connections, and shielding are required for the board design to achieve desired modem performance and to attain EMI certification. Other aspects of proper noise-suppression engineering practices are beyond the scope of this developer’s guide. The developer should consult noise suppression techniques described other sources, such as technical publications, electronics and electrical engineering text books, and component supplier application notes. PC Board Layout Guidelines In a 4-layer design, provide adequate ground plane covering the entire board. In 4-layer designs, power and ground are typically on the inner layers. All power and ground traces should be 0.05 inches wide. The recommended hole size for the SocketModem pins is 0.036 in. +/-0.003 in. in diameter. Spacers can be used to hold the SocketModem vertically in place during the wave solder process. All creepages and clearances for the SocketModem have been designed to meet requirements of safety standards EN60950 or EN60601. The requirements are based on a working voltage of 125V or 250V. When the recommended DAA* circuit interface is implemented in a third party design, all creepage and clearance requirements must be strictly followed in order to meet safety standards. The third party safety design must be evaluated by the appropriate national agency per the required specification. User accessible areas: Based on where the third party design is to be marketed, sold, or used, it may be necessary to provide an insulating cover over all TNV exposed areas. Consult with the recognized safety agency to determine the requirements. Note: Even if the recommended design considerations are followed, there are no guarantees that a particular system will comply with all the necessary regulatory requirements. It is imperative that specific designs be completely evaluated by a qualified/recognized agency. *DAA stands for Data Access Arrangement. DAA is the telephone line interface of the SocketModem. Electromagnetic Interference (EMI) Considerations The following guidelines are offered specifically to help minimize EMI generation. Some of these guidelines are the same as, or similar to, the general guidelines but are mentioned again to reinforce their importance. In order to minimize the contribution of the SocketModem-based design to EMI, the designer must understand the major sources of EMI and how to reduce them to acceptable levels. ● Keep traces carrying high frequency signals as short as possible. ● Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers for ground and power distribution. ● Decouple power from ground with decoupling capacitors as close to the SocketModem power pins as possible. ● Eliminate ground loops, which are unexpected current return paths to the power source and ground. ● Decouple the telephone line cables at the telephone line jacks. Typically, use a combination of series inductors, common mode chokes, and shunt capacitors. Methods to decouple telephone lines are similar to decoupling power lines; however, telephone line decoupling may be more difficult and deserves additional attention. A commonly used design aid is to place footprints for these components and populate as necessary during performance/EMI testing and certification. ● Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple power lines are similar to decoupling telephone lines. ● Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits. ● Locate cables and connectors so as to avoid coupling from high frequency circuits.

Chapter 1 – Universal Socket Connectivity 12 Multi-Tech Systems, Inc. GPRS SocketModem Developer’s Guide (S000521A) ● Lay out the highest frequency signal traces next to the ground grid. ● If a multilayer board design is used, make no cuts in the ground or power planes and be sure the ground plane covers all traces. ● Minimize the number of through-hole connections on traces carrying high frequency signals. ● Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius turns are better. ● On 2-layer boards with no ground grid, provide a shadow ground trace on the opposite side of the board to traces carrying high frequency signals. This will be effective as a high frequency ground return if it is three times the width of the signal traces. ● Distribute high frequency signals continuously on a single trace rather than several traces radiating from one point. Electrostatic Discharge Control All electronic devices should be handled with certain precautions to avoid damage due to the accumulation of static charge. See the ANSI/ESD Association Standard (ANSI/ESD S20.20-1999) – a document “for the Development of an Electrostatic Discharge Control for Protection of Electrical and Electronic Parts, Assemblies and Equipment.” This document covers ESD Control Program Administrative Requirements, ESD Training, ESD Control Program Plan Technical Requirements (grounding/bonding systems, personnel grooming, protected areas, packaging, marking, equipment, and handling), and Sensitivity Testing. Multi-Tech Systems, Inc. strives to follow all of these recommendations. Input protection circuitry has been incorporated into the Multi-Tech devices to minimize the effect of this static buildup, proper precautions should be taken to avoid exposure to electrostatic discharge during handling. Multi-Tech uses and recommends that others use anti-static boxes that create a faraday cage (packaging designed to exclude electromagnetic fields). Multi-Tech recommends that you use our packaging when returning a product and when you ship your products to your customers.

Chapter 2 – SocketModem Cell & iCell GPRS (MTSMC-G2) Multi-Tech Systems, Inc. GPRS SocketModem Developer’s Guide (S000521A) 45 Microphone Inputs Note: For Voice Build Only. The MIC inputs are differential ones. They already include the convenient biasing for an electret microphone (0.5 mA and 2 Volts). This electret microphone can be directly connected on these inputs. The impedance of the microphone has to be around 2K. These inputs are the standard ones for a handset design. The gain of the MIC inputs is internally adjusted. The gain can be tuned from 30dB to 51dB. The connection to the microphone is direct. Changing the Quad Band If for any reason, such as moving the modem from one geographical area to another, you want to change the band, you can accomplish this by using the +WMBS AT Command. Steps for Changing the GSM Band Use a terminal application such as HyperTerminal for entering the AT Command. 1. To open HyperTerminal, click Start. Then select Programs > Accessories > Communications. Then click HyperTerminal. 2. When the command window opens, type AT+WMBS=<Band><Param>. Press Enter. 3. For <Band>, enter the option you desire: 4 = Dual-band mode 850/1900MHz 5 = Dual-band mode 900/1800MHz For <Param>, enter the option you desire: 0 = Modem must be reset in order to use the specified band(s). This is the default. 1 = Modem restarts immediately using the specified band(s). Example: AT+WMBS=4,0. Press Enter. MIC2NMIC2PC1C1 = 22pF to 100 pF33 pF recommended
