Chapter 1 – Universal Socket Connectivity Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342G) 5 Design Considerations Noise Suppression Design Considerations Engineering noise-suppression practices must be adhered to when designing a printed circuit board (PCB) containing the SocketModem module. Suppression of noise is essential to the proper operation and performance of the modem itself and for surrounding equipment. Two aspects of noise in an OEM board design containing the SocketModem must be considered: on-board/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. Of particular concern is noise in frequency ranges affecting modem performance. On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted off-board is a separate, but equally important, concern. This type of noise can affect the operation of surrounding equipment. Most local 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 designer guide. The designer should consult noise suppression techniques described in technical publications and journals, 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. A spacer should be placed on pin 32 and pin 64 of the SocketModem. A suggested part number for the spacer is BIVAR 938-0.130 for P1 (0.310in) option SocketModems. The spacers can be left on permanently and will not effect operation. 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 module.
Chapter 1 – Universal Socket Connectivity Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342G) 6 Electromagnetic Interference (EMI) Considerations The following guidelines are offered to specifically 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. 1. Keep traces carrying high frequency signals as short as possible. 2. Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers for ground and power distribution. 3. Decouple power from ground with decoupling capacitors as close to the SocketModem module power pins as possible. 4. Eliminate ground loops, which are unexpected current return paths to the power source and ground. 5. 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. 6. Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple power lines are similar to decoupling telephone lines. 7. Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits. 8. Locate cables and connectors so as to avoid coupling from high frequency circuits. 9. Lay out the highest frequency signal traces next to the ground grid. 10. 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. 11. Minimize the number of through-hole connections on traces carrying high frequency signals. 12. Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius turns are better. 13. 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. 14. 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 HSDPA Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342G) 21 Operating Modes The table below briefly summarizes the various operating modes. Mode Function GSM / GPRS / UMTS / HSDPA SLEEP Power saving mode set automatically when no call is in progress and the USB connection is suspended by host or not present. GSM IDLE Software is active. Once registered to the GSM network, paging with BTS is carried out in order to achieve synchrony with the GSM network. The repetition rate depends on the parameter BSPA_Multiframe. The module is ready to send and receive. GSM TALK Connection between two subscribers is in progress. Power consumption depends on the GSM network coverage and several connection settings (e.g. DTX off/on, FR/EFR/HR, hopping sequences and antenna connection). The following applies when power is to be measured in TALK_GSM mode: DTX off, FR and no frequency hopping, otherwise same as for IDLE measurements. Normal operation GPRS IDLE Module is attached and ready for GPRS data transfer, but no data is currently sent or received. GPRS DATA GPRS data transfer in progress. Power consumption depends on network settings (e.g. power control level), uplink / downlink data rates and GPRS configuration (e.g. used multislot settings). EGPRS DATA EGPRS data transfer in progress. Power consumption depends on network settings (e.g. power control level), uplink / downlink data rates and EGPRS configuration (e.g. used multislot settings). UMTS / HSDPA IDLE Module is attached and ready for UMTS / HSDPA data transfer, but no data is currently sent or received. UMTS DATA UMTS data transfer in progress. Power consumption depends on network settings (e.g. TPC Pattern) and data transfer rate. HSDPA DATA HSDPA data transfer in progress. Power consumption depends on network settings (e.g. TPC Pattern) and data transfer rate.
Chapter 2 – SocketModem HSDPA Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342G) 22 Turn off the Module Using AT Command The best and safest approach to powering down is to issue the AT^SMSO command. This procedure lets the module log off from the network and allows the software to enter into a secure state and safe data before disconnecting the power supply. The mode is referred to as Power-down mode. In this mode, only the RTC stays active. After sending AT^SMSO do not enter any other AT commands. There are two ways to verify that the module turns off: Wait for the ”OK” – response. It indicates that data has been stored non-volatile and that the module turns off in less than TBD second. Important Note: The SocketModem requires a reset to become active again. USB Interface The Module supports a USB 1.1 Full Speed (12Mbit/s) device interface. The USB I/O-pins are capable of driving the signal at min 3.0V. To properly connect the module’s USB interface to the host a USB 1.1 compatible connector is required. Furthermore, the USB modem driver for Windows XP delivered with the module be installed as described in the Installation Guide. While the USB connection is active, the module will not change into SLEEP Mode. To enable switching into SLEEP mode the USB host has to be able to change into suspend mode. On incoming calls, the module will then generate a remote wake up request to resume the USB connection. This can be realized by means of the HOST_WAKEUP line. If no call, data or message transfer is in progress, the HOST_WAKEUP line is passive. To save power, the host could then shut down the USB interface. If a call or other request (URC’s, messages) arrives, the host can be woken up again by activation of HOST_WAKEUP (passive to active transition). Analog Audio Interface The module supports one analog audio interface available on the board to board connector. The following two pictures show the balanced headset interface with microphone feeding and the line interface. Network Connectivity Status Signals One status signal is provided for signaling the module’s connectivity status (58 of the socket).
