*The SocketModem device may respond to a shorter reset pulse.
Reset Line Interface for the MT5656SMI and MT2456SMI. The modem’s reset line
employs a .01uF cap and a 10K pull up resistor. Care must be taken to ensure the system
the modem is place into is not affected by the added capacitance of the reset line. It is not
advisable to use an open collector driver in the embedded system's reset circuitry to drive a
reset signal to the embedded modem and other I.C.s in the customer’s design. Rather, 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 and CDMA (MTSMC-G and MTSMC-C). 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 EDGE with pull-up (MTSMC-E). The active low –RESET input resets the device logic
and returns the configuration of the device to the original factory default values of "stored
values" in the NVRAM. –RESET is tied to VCC through a time-constant circuit for “Power-onReset” functionality. The SocketModem is ready to accept commands after a fixed amount of
time after power-on or reset.

data from the modem on RXD. –RTS OFF indicates to the SocketModem that it should not
transfer data on the RXD.
In the command state, the modem ignores –RTS.
Note: When the –RTS pin is not in use, it should be tied low.
* 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.

Design Considerations
Noise Suppression Design Considerations
Engineering noise-suppression practices must be adhered to when designing a printed circuit board (PCB) containing
the SocketModem. 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.
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.

Chapter 1 – Universal Socket Connectivity
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.
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 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.
Phone Line Warning Statement for the Developer Board
Use extreme caution when the phone line is installed due to live energized components. In fact, do not touch any
components on the board while the phone line is installed.
In addition, the phone line should be detached when making modifications to or servicing the developer board.
For other telephone warnings, refer to the Telecom Warnings listed earlier in this chapter.

The flash programming protocol is provided "AS IS” without warranty.
Important: When interacting with the boot code, it is possible to make the modem inoperable.
Use extreme caution.
Programming the Modem
There are two ways to start flash programming a modem. It can be programmed
1. From “AT” mode
2. When the modem powers up.
The following table shows how a modem is programmed.
DTE
Modem
Comments
AT*FS\r
Handshake Sequence
This effectively “restarts” the modem so that it enters the boot code.
M’s
Many M’s are sent (10 milliseconds apart) at 19200 baud.
This is where the handshake starts if the modem is just powered up.
U is sent at 19200 baud if M’s are received within 100 milliseconds of
power up. If the M’s are not received within 100 milliseconds, then
the modem starts up normally. If the AT*FS command is used, then
you have 1 second (1000mS) to perform the handshake.
Sent at 19200 baud.
M if can receive at 9600/19200/38400/57600/115200
I if modem will be programmed at 9600
J if modem will be programmed at 19200

Data Bytes (do not include the Length or Address bytes in that
calculation).
If bytes are programmed and verified.
If verify fails or checksum is bad.
Retry the block 3 times on an ERROR.
More of the above sequence until all the data bytes have been sent
to the modem.
This ends programming and restarts the modem.

Other Programming Concerns
1.

5.
The packets sent to the modem must be presorted by address and aligned on 128 byte boundaries (i.e., each
packet must start on an address that is a multiple of 128).
The packets should also be a minimum of 128 bytes with the non-programmed bytes set to the hex value of FF.
The packets sent to the modem must not span a 4K boundary (i.e., start the packet before it and go over the
boundary in the middle of the packet).
The 10-millisecond delay between M’s at the beginning of the handshake is so that the modem can sync up to
the start bit. If the M’s are sent one right after another, a data bit might be mistaken as a start bit.
Multi-Tech firmware files are in Intel Hex Format and must be read in and formatted into 128-4096 byte blocks
before being sent to the modem.
Information about the Intel Hex Format
An Intel Format Hex File is a text file consisting of “records”, one per line, that start with a “:” character and include
only digits 0-9 and letters A-F. There are three different record types: Extended Address Records, Data Records, and
End of File Records.
Data records contain the actual data that is to be programmed into a device. The address contained in the data
record needs to be combined with an extended address (by adding the extended address shifted four bits left to the
data record address) to determine the actual programming address for the data. If no extended address record is
before a given data record in the file, then the extended address value is assumed to be zero.

Certifications, Approvals, Compliance, and
Requirements
Wireless Approvals (GSM, CDMA)
The Multi-Tech SocketModem is Industry and/or Carrier Approved as an End Product modem. When integrated and used
with an antenna system that was part of the Multi-Tech modem certification, no additional approvals or certification is
required (however, CDMA has a few exceptions) for the device you develop as long as the following are met:
•
PTCRB Requirements:
The antenna system cannot be altered.
•
Model Identification:
IMPORTANT
When the wireless carrier asks you to provide the modem's model identification,
give the Multi-Tech wireless model identification, not the identification of the host device.
See the label example below.
The Multi-Tech model identification allows the carrier to verify the modem as one of its approved models.
This information is located on the modem's label.
Example:
The following is an example of Multi-Tech's wireless model identification:
MTSMC-G-F4 – Multi-Tech wireless GPRS model identification.

CDMA products.
Approved terminal equipment and approved protective circuitry shall prominently display the following
information using the format shown below:
• Responsible party
• Product Identification
• Equipment Code
• Ringer Equivalence
• Ringer Type
• Indication that the product meets the requirements of FCC Part 68
The information required by the first five items shall correspond to the records in the ACTA (America's Carriers
Telecommunications Association) database of approved equipment. The required information shall be encoded
in the following format:
US: AAAEQ##TXXX
Where:
US: Is a fixed field that indicates the equipment meets all requirements of 47 CFR Part 68, including the

AAA is the responsible party’s Grantee Code obtained previously from the FCC’s Common Carrier Bureau or
currently from ACTA.
EQ Is an Equipment Code indicating to the Service Provider any special signal handling or billing requirements.
The Equipment codes are listed in Annex A (normative).
## is the Ringer Equivalence Number without a decimal point (e.g. REN of 1.0 = 10, REN of 0.3 = 03). In the
case of a “Z” ringer, ZZ shall appear. In the case of approved equipment without a network interface and
equipment not connecting to circuits with analog ringing supplied then “NA” shall appear.
T is the ringer type letter associated with the Ringer Equivalence Number, in accordance with the technical
requirements. In the case of approved equipment without a network interface and equipment not connecting to
circuits with analog ringing supplied, the letter “N” shall appear.
XXX Is a product identifier, unique when combined with the responsible party’s Grantee Code, of at least one
and up to nine alphanumeric characters (including one or more dashes (-) if desired. A dash shall not appear as
the first or last character nor shall the identifier consist entirely of dashes). The responsible party shall define this
identifier.
Label Physical Characteristics
The information required above shall be permanently affixed and legible without magnification. It may be
etched, engraved, stamped, indelibly printed, or otherwise permanently marked. Alternatively, the required
information may be permanently marked on a nameplate of metal, plastic or other material fastened to the
enclosure by welding, riveting or with a permanent adhesive. Such a nameplate shall be able to last for the
expected lifetime of the equipment and shall not be readily detachable.
Labeling Continuity and Changes
The labeling content and format requirements in effect when a product was approved shall be effective for
the life of the product. The labeling content and format requirements in effect at approval shall also continue
to be effective for modified products. However, the responsible party shall have the option of conforming a
product's labeling to current content and format requirements at any time.
Other Label Requirements
The label shall be placed in one of the following locations in a location where it can be found after
installation:
• on an outside surface

Chapter 1 – Universal Socket Connectivity
Canadian Labeling Requirements (for Dial-Up Modems)
The following requirements are established under section 69.3 of the Telecommunications Act for purposes of
section 5 of the Telecommunications Apparatus Regulations.
Registered equipment shall bear the following identifying marks, and the Declaring Party shall ensure that these
marks are permanently affixed to the equipment:
(a) The registration number — Specifications of this mark are given in the document: Self-Marking of the
Certification/Registration Number on Terminal Equipment — Application Procedure and Agreement; and
(b) The model identification number under which the product was registered.
A statement of compliance with Industry Canada requirements, such as the one given below, shall accompany
each unit of equipment whether registered under this procedure or previously certified:
"This product meets the applicable Industry Canada technical specifications"
For terminal equipment intended for connection to loop-start or ground-start interfaces, the Ringer Equivalence
Number (REN) must be calculated as per Section 1.8 of CS-03, Part I. A REN higher than that determined may
be assigned by manufacturers to allow for production variations. The REN must be marked on the terminal
equipment itself or added to the note below. A note similar to the following shall accompany each unit of
equipment whether registered under this procedure or previously certified:
"The Ringer Equivalence Number is an indication of the maximum number of devices allowed to be
connected to a telephone interface. The termination on an interface may consist of any combination of
devices subject only to the requirement that the sum of the RENs of all the devices does not exceed
five".
Pursuant to section 69.3 of the Telecommunications Act, certified or self-declared TE will bear a valid identifying
certification number or registration number. The marking of the certification or registration number on the product
shall be as follows:
(a) TAC holder/DP will be responsible for permanently affixing the certification/registration number on the TE.
The certification/registration number (see example below) identifies Certified or self-declared TE to the
public, representatives of the telecommunications common carriers, the Department, and other interested
parties. The letter height must be no less than 1.5 mm and the letters must be legible without magnification.
(b) For integrated devices, e.g. a modem or one that is intended to become a sub-assembly of host equipment
e.g. a data terminal, computer etc. that are designed to interface directly with the network, the
certification/registration number shall be affixed to the integrated device itself.
(c) The certification/registration number for a packaged TE will denote that the total package has been
registered. However, the marking will normally be placed on that unit of the package which connects to the
network; e.g., in a PBX the marking will be placed on the common equipment which connects to the
network, rather than on plug-in components which may be added later. The Terminal Equipment List will
show the common equipment but not the standard station apparatus or any proprietary station apparatus.
(d) The marking format of the certification/registration number is as follows:
IC: XXXXXX-YYYYYYYY
Where:
• The letters "IC" have no other meaning or purpose than to identify the Industry Canada
certification/registration number, and
• “XXXXXX-YYYYYYYY” is the certification/registration number; “XXXXXX” is the Company Number¹ (CN);
it consists of up to six alphanumeric characters (A-Z, 0-9) assigned by Industry Canada; and
“YYYYYYYY” is the Unique Product Number (UPN); it consists of up to eight alphanumeric characters (AZ, 0-9) assigned by the applicant. Other characters, (such as & # *-) may not be used. Alphabetic
characters must be capitalized.
¹ Note: The Company Number of registered equipment ends with an alphabetic character.
(e) Certification Numbers granted prior to the implementation of the above marking format are grandfathered.
(i) For previously certified TE, the self-marking format shall consist of the old certification number preceded
by “IC:” For example, if the certification number is “123 1234 A”, then the self-mark would read “IC: 123
1234 A”.
(ii) For a new model that is registered to a family of previously certified TE, the self-marking format shall be:
IC: XXXXXX-ZZZZZZZZ
Where:
• “XXXXXX” is the Company Number, as in (d) above; and
• “ZZZZZZZZ” is either the old certification number minus the old company number, or a new Unique
Product Number assigned by the applicant. For example, if a new model is registered to the family of
products with certification number “123 1234 A”, and that the Company Number for the registration is
“123A”, then the self-mark for this new model would read “IC: 123A-1234 A”. If the applicant decides to
replace “1234 A” with a new UPN, say “5678", then the self-mark would read “IC: 123A-5678".

7.
8.
The grant of a Telepermit for any item of terminal equipment indicates only that Telecom has accepted that
the item complies with minimum conditions for connection to its network. It indicates no endorsement of the
product by Telecom, nor does it provide any sort of warranty. Above all, it provides no assurance that any
item will work correctly in all respects with another item of Telepermitted equipment of a different make or
model, nor does it imply that any product is compatible with all of Telecom’s network services.
This equipment is not capable under all operating conditions of correct operating conditions of correct
operation at the higher speed which it is designated. 33.6 kbps and 56 kbps connections are likely to be
restricted to lower bit rates when connected to some PSTN implementations. Telecom will accept no
responsibility should difficulties arise in such circumstances.
Immediately disconnect this equipment should it become physically damaged, and arrange for its disposal or
repair.
This modem shall not be used in any manner which could constitute a nuisance to other Telecom
customers.
This device is equipped with pulse dialing, while the Telecom standard is DTMF tone dialing. There is no
guarantee that Telecom lines will always continue to support pulse dialing.
Use of pulse dialing, when this equipment is connected to the same line as other equipment, may give rise
to 'bell tinkle' or noise and may also cause a false answer condition. Should such problems occur, the user
should NOT contact the Telecom Faults Service.
The preferred method of dialing is to use DTMF tones, as this is faster than pulse (decadic) dialing and is
readily available on almost all New Zealand telephone exchanges.
Warning Notice: No '111' or other calls can be made from this device during a mains power failure.
This equipment may not provide for the effective hand-over of a call to another device connected to the
same line.
Some parameters required for compliance with Telecom’s Telepermit requirements are dependent on the
equipment (PC) associated with this device. The associated equipment shall be set to operate within the
following limits for compliance with Telecom’s Specifications:
For repeat calls to the same number:
• There shall be no more than 10 call attempts to the same number within any 30 minute period for
any single manual call initiation, and
• The equipment shall go on-hook for a period of not less than 30 seconds between the end of one
attempt and the beginning of the next attempt.
For automatic calls to different numbers:
• The equipment shall be set to ensure that automatic calls to different numbers are spaced such
that there is no less than 5 seconds between the end of one call attempt and the beginning of
another.
For correct operation, total of the RN’s of all devices connected to a single line at any time should not
exceed 5.
South African Statement
This modem must be used in conjunction with an approved surge protection device.

Chapter 2 – SocketModem (MT5600SMI & MT5656SMI)
SocketModem Parallel Interface
The modem supports a 16550A interface in parallel interface versions. The 16550A interface can operate in FIFO mode or
non-FIFO mode. Non-FIFO mode is the same as the 16450-interface operation. FIFO mode’s unique operations are described
in this chapter.
Overview
The modem emulates the 16450/16550A interface and includes both a 16-byte receiver data first-in first-out buffer
(RX FIFO) and a 16-byte transmit data first-in first-out buffer (TX FIFO).
FIFO Mode Selected
When FIFO mode is selected in the FIFO Control Register (FCR0 = 1), both FIFOs are operative. Furthermore,
when FIFO mode is selected, DMA operation of the FIFO can also be selected (FCR3 = 1).
FIFO Mode Not Selected
When FIFO mode is not selected, operation is restricted to a 16450-interface operation.
Receive Data
Received Data is read by the host from the Receiver Buffer (RX Buffer). The RX Buffer corresponds to the
Receiver Buffer Register in a 16550A device. In FIFO mode, the RX FIFO operates transparently behind the RX
Buffer. Interface operation is described with reference to the RX Buffer in FIFO and non-FIFO modes.
Transmit Data
Transmit Data is loaded by the host into the Transmit Buffer (TX Buffer). The TX Buffer corresponds to the
Transmit Holding Register in a 16550A device. In FIFO mode, the TX FIFO operates transparently behind the TX
Buffer. Interface operation is described with reference to the TX Buffer in both FIFO and non-FIFO modes.
Receiver FIFO Interrupt Operation
Receiver Data Available Interrupt
When the FIFO mode is enabled (FCR0 = 1) and receiver interrupt (RX Data Available) is enabled (IER0 =
1), receiver interrupt operation is as follows:
1. The Receiver Data Available Flag (LSR0) is set as soon as a received data character is available in the
RX FIFO. LSR0 is cleared when RX FIFO is empty.
2. The Receiver Data Available Interrupt code (IIR0-IIR4 = 4h) is set whenever the number of received
data bytes in the RX FIFO reaches the trigger level specified by FCR6-FCR7 bits. It is cleared
whenever the number of received data bytes in the RX FIFO drops below the trigger level specified by
FCR6-FCR7 bits.
3. The HINT interrupt is asserted whenever the number of received data bytes in the RX FIFO reaches the
trigger level specified by FCR6-FCR7 bits. HINT interrupt is de-asserted when the number of received
data bytes in the RX FIFO drops below the trigger level specified by FCR6-FCR7 bits.
Receiver Character Timeout Interrupts
When the FIFO mode is enabled (FCR0 = 1) and receiver interrupt (Receiver Data Available) is enabled
(IER0 = 1), receiver character timeout interrupt operation is as follows:
1. A Receiver character timeout interrupt code (IIR0-IIR3 = Ch) is set if at least one received character is
in the RX FIFO, the most recent received serial character was longer than four continuous character
times ago (if 2 stop bits are specified, the second stop bit is included in this time period), and the most
recent host read of the RX FIFO was longer than four continuous character times ago.
Transmitter FIFO Interrupt Operation
Transmitter Empty Interrupt
When the FIFO mode is enabled (FCR0 = 1) and transmitter interrupt (TX Buffer Empty) is enabled (IER0
=1), transmitter interrupt operation is as follows:
1. The TX Buffer Empty interrupt code (IIR0-IIR3 = 2h) will occur when the TX Buffer is empty. It is cleared
when the TX Buffer is written to (1 to 16 characters) or the IIR is read.
2. The TX Buffer Empty indications will be delayed 1 character time minus the last stop bit time whenever
the following occur: THRE = 1 and there have not been at least two bytes at the same time in the TX
FIFO Buffer since the last setting of THRE was set. The first transmitter interrupt after setting FCR0 will
be immediate.

IER – Interrupt Enable Register
(Addr = 1, DLAB = 0)
The IER enables five types of interrupts that can separately assert the HINT output signal (See the Interrupt Sources
and Reset Control table in the IIR section of this chapter). A selected interrupt can be enabled by setting the
corresponding enable bit to a 1, or disabled by setting the corresponding enable bit to a 0. Disabling an interrupt in
the IER prohibits setting the corresponding indication in the IIR and assertion of HINT. Disabling all interrupts
(resetting IER0 – IER3 to a 0) inhibits setting of any Interrupt Identifier Register (IIR) bits and inhibits assertion of the
HINT output. All other system functions operate normally, including the setting of the Line Status Register (LSR) and
the Modem Status Register (MSR).

When FIFO mode is selected (FCR0 = 1), FCR3 selects non-DMA operation (FCR3 = 0) or DMA
operation (FCR3 = 1). When FIFO mode is not selected (FCR0 = 0), this bit is not used (the
modem operates in non-DMA mode in 16450 operation).
DMA Operation in FIFO Mode
RXRDY will be asserted with the number of characters in the RX FIFO us equal to or greater
than the value in the RX FIFO Trigger Level (IIR0-IIR3 = 4h) or the received character
timeout (IIRO-IIR3 = Ch) has occurred. RXTDY will go inactive when there are no more
characters in the RX FIFO.
TXRDY will be asserted when there are one or more empty (unfilled) locations in the TX
FIFO. TXRDY will go inactive when the TX FIFO is completely full.
Non-DMA Operation in FIFO Mode
RXRDY will be asserted when there are one or more characters in the RX FIFO. RXRDY
will go inactive when there are no more characters in the RX FIFO.
TXRDY will be asserted when there are no characters in the TX FIFO. TXRDY will go
inactive when the character is loaded into the TX FIFO Buffer.
Bit 2
TX FIFO Reset
When FCR2 is a 1, all bytes in the TX FIFO are cleared. This bit is cleared automatically by the
modem.
Bit 1
RX FIFO Reset
When FCR1 is a 1, all bytes in the RX FIFO are cleared. This bit is cleared automatically by the
modem.
Bit 0

IIR – Interrupt Identifier Register
(Addr = 2)
The Interrupt Identifier Register (IIR) identifies the existence and type of up to five prioritized pending interrupts. Four
priority levels are set to assist interrupt processing in the host. The four levels, in order of decreasing priority, are
Highest: Receiver Line Status, 2: Receiver Data Available or Receiver Character Timeout. 3: TX Buffer Empty, and 4:
Modem Status.
When the IIR is accessed, the modem freezes all interrupts and indicates the highest priority interrupt pending to the
host. Any change occurring in interrupt conditions are not indicated until this access is complete.
Bits 7-6
FIFO Mode
These two bits copy FCR0.
Bits 5-4
Not Used
Always 0.
Bits 3-1
Highest Priority Pending Interrupt
These three bits identify the highest priority pending interrupt (Table below). Bit 3 is
applicable only when FIFO mode is selected; otherwise, bit 3 is a 0.
Bit 0
Interrupt Pending
When this bit is a 0, an interrupt is pending; IIR bits 1-3 can be used to determine the source
of the interrupt. When this bit is a 1, an interrupt is not pending

LCR – Line Control Register
(Addr = 3)
The Line Control Register (LCR) specifies the format of the asynchronous data communications exchange.
Bit 7
Divisor Latch Access Bit (DLAB)
This bit must be set to a 1 to access the Divisor Latch Registers during a read or write operation.
It must be reset to a 0 to access the Receiver Buffer, the Transmitter Buffer, or the Interrupt
Enable Register.
Bit 6
Set Break
When bit 6 is a 1, the Transmit data is forced to the break condition, i.e., space (0) is sent. When
bit 6 is a 0, break is not sent. The Set Break bit acts only on the Transmit data and has no effect
on the serial in logic.
Bit 5
Stick Parity
When Parity is enabled (LCR3 = 1) and stick parity is selected (LCR5 = 1), the parity bit is
transmitted and checked by the receiver as a 0 if even parity is selected (LCR4 – 1) or a 1 if odd
parity is selected (LCR4 = 0). When the stick parity is not selected (LCR3 = 0), parity is transmit
and checked as determined by the LCR3 and LCR4 bits.
Bit 4
Even Parity Select (EPS)
When parity is enabled (LCR3 = 1) and stick parity is not selected (LCR5 = 0), the number of 1s
transmitted or checked by the receiver in the data word bits and parity bit is either even (LCR4 =
1) or odd (LCR4 = 0).
Bit 3
Enable Parity (PEN)
When bit 3 is a 1, a parity bit is generated in the serial out (transmit) data stream and checked in
the serial in (receive) data stream as determined by the LCR4 and LCR5 bits. The parity bit is
located between the last data bit and the first stop bit.
Bit 2
Number of Stop GBITS (STB)
This bit specifies the number of stop bits in each serial out character. If bit 2 is a 0, one stop bit is
generated regardless of word length. If bit 2 is a 1 and 5-bit word length is selected, one and
one-half stop bits are generated. If bit 2 is a 1 and 6-, 7-, or 8-bit word length is selected, two
stop bits are generated. The serial in logic checks the first stop bit only, regardless of the number
of stop bits selected.
Bit 1-0

LSR – Line Status Register
(Addr = 5)
This 8-bit register provides status information to the host concerning data transfer
Bit 7
RX FIFO Error
In the 16450 mode, this bit is not used and is always 0.
In the FIFO mode, this bit is set if there are one or more characters in the RX FIFO with parity
error, framing error, or break indication detected. This bit is reset to a 0 when the host reads the
LSR and note of the above conditions exist in the RX FIFO.
Bit 6
Transmitter Empty (TEMT)
This bit is set to a 1 whenever the TX Buffer (THR) and equivalent of the Transmitter Shift
Register (TRS) are both empty. It is reset to a 0 whenever either the THR or the equivalent of the
TSR contains a character.
In the FIFO mode, this bit is set to a 1 whenever the TX FIFO and the equivalent of the TSR are
both empty
Bit 5
Transmitter Holding Register Empty (THRE) [TX Buffer Empty]
This bit, when set, indicates that the TX Buffer is empty and the modem can accept a new
character for transmission. In addition, this bit causes the modem to issue an interrupt to the host
when the Transmit Holding Register Empty Interrupt Enable bit (IIR1) is set to 1. The THRE bit is
set to a 1 when a character is transferred from the TX Buffer. The bit is reset to 0 when a byte is
written into the TX Buffer by the host.
In the FIFO mode, this bit is set when the TX FIFO is empty; it is cleared when at least one byte
is in the TX FIFO.
Bit 4
Break Interrupt (BI)
This bit is set to a 1 whenever the received data input is a space (logic 0) for longer than two full
word lengths plus 3 bits. The BI is reset when the host reads the LSR.
Bit 3
Framing Error (FE)
This bit indicates that the received character did not have a valid stop bit. The FE bit is set to a 1
whenever the stop bit following the last data bit or parity bit is detected as a logic o (space). The
FE bit is reset to a 0 when the host reads the LSR.
In the FIFO mode, the error indication is associated with the particular character in the FIFO it
applies to. The FE bit set to a 1 when this character is loaded into the RX Buffer.
Bit 2
Parity Error (PE)
This bit indicates that the received data character in the RX Buffer does not have the correct
even or odd parity, as selected by the Even Parity Select bit (LCR4) and the Stick Parity bit
(LCR5). The PE bit is reset to a 0 when the host reads the LSR.
In the FIFO mode, the error indication is associated with the particular character in the FIFO it
applies to. The PE bit set to a 1 when this character is loaded into the RX Buffer.
Bit 1
Overrun Error (OE)
This bit is set to a 1 whenever received data is loaded into the RX Buffer before the host has
read the previous data from the RX Buffer. The OE is reset to a 0 when the host reads the LSR.
In the FIFO mode, if data continues to fill beyond the trigger level, an overrun condition will occur
only if the RX FIFO is full and the next character has been completely received.
Bit 0
Receiver Data Ready (DR)
This bit is set to a 1 whenever a complete incoming character has been received and transferred
into the RX Buffer. The DR bit is reset to a 0 when the host reads the RX Buffer.
In the FIFO mode, the DR bit is set when the number of received data bytes in the RX FIFO
equals or exceeds the trigger level specified in the FCR0-FCR1.

Chapter 2 – SocketModem (MT5600SMI & MT5656SMI)
MSR – Modem Status Register
(Addr = 6)
The Modem Status Register (MSR) reports current state and change information of the modem. Bits 4-7 supply
current state and bits 0-3 supply change information. The change bits are set to a 1 whenever a control input from the
modem changes state from the last MSR read by the host. Bits 0-3 are reset to 0 when the host reads the MSR or
upon reset.
Whenever bits 0, 1, 2, or 3 are set to a 1, a Modem Status Interrupt (IIR0-IIR3 = 0) is generated.
Bit 7
Data Carrier Detect (DCD)
This bit indicates the logic state of the DCH# (RLSD#) output. If Loopback is selected (MCR4 =
1), this bit reflects the state of the Out2 bit in the MCR (MCR3).
Bit 6
Ring Indicator (RI)
This bit indicates the logic state of the RI# output. If Loopback is selected (MCR4 = 1), this bit
reflects the state of the Out1 bit in the MCR (MCR2).
Bit 5
Data Set Ready (DSR)
This bit indicates the logic state of the DSR# output. If Loopback is selected (MCR4 = 1), this bit
reflects the state of the DTR in the MCR (MCR0).
Bit 4
Clear to Send (CTS)
This bit indicates the logic state of the CTS# output. If Loopback is selected (MCR4 = 1), this bit
reflects the state of the RTS bit in the MCR (MCR1).
Bit 3
Delta Data Carrier Detect (DDCD)
This bit is set to a 1 when the DCD bit changes state since the host last read the MSR.
Bit 2
Trailing Edge of Ring Indicator (TERI)
This bit is set to a 1 when the RI bit changes from a 1 to a 0 state since the host last read the
MSR.
Bit 1
Delta Data Set Ready (DDSR)
This bit is set to a 1 when the DSR bit has changed since the host last read the MSR.
Bit 0
Delta Clear to Send (DCTS)
This bit is set to a 1 when the CTS bit has changed since the MSR the host last read the MSR.
RBX – RX Buffer (Receiver Buffer Register)
(Addr = 0, DLAB = 0)
The RX Buffer (RBR) is a read-only register at location 0 (with DLAB = 0). Bit 0 is the least significant bit of the data
and is the first bit received.
THR – TX Buffer (Transmitter Holding Register)

SocketModem Parallel Interface Internal Registers
The SocketModem parallel interface is a mimic of a 16C550A UART. It is similar to the MIMIC interface used in the Zilog
Z80189. The SocketModem mimic (MMM) takes advantage of this standard interface while replacing the serial to parallel data
transfer with a less complicated parallel to parallel data transfer.
The MMM interface controls an 8-bit parallel data transfer which is typically interrupt driven. Interrupts usually indicate one or
both of two conditions: (1) the receive (RX) FIFO has either reached a trigger level or time-out condition and needs to be
emptied and/or (2) the transmit (TX) FIFO is empty and waiting for more data from the Host. An interrupt can also be triggered
by a change in the modem status register (i.e., loss of carrier) or by the occurrence of errors in the line status register (overrun,
parity, framing, break detect).
In addition to the receive and transmit FIFOs, there are twelve other control/status registers called the MMM register set which
can be accessed through this interface.
Overview
SocketModem MIMIC (MMM) Operation
Data flow through MMM is bi-directional. Simultaneously, data can flow from the host through the transmit FIFO
to the SocketModem controller, and data can flow from SocketModem controller through the receive FIFO to the
Host. In the receive path, 8-bit data is asynchronously received (from the SocketModem controller) by the
receive FIFO where it is stored along with associated three error bits. The error bits must arrive (via a
SocketModem controller I/O write to MMM shadow line status register) prior to receiving the actual data bits. The
error bits are then temporarily stored so they may be written, with associated data bits, to the 11-bit wide RX
FIFO.
After every data write, the RX FIFO write pointer is incremented. RX FIFO trigger levels, data ready signal, and
time-out counter are checked to see if a Host-interrupt needs to be sent. The data ready signal will be activated
and MMM sits poised to accept another data word.
We highly recommend the host should read the MMM IIR register to determine the type of interrupt. Then it might
check bit 7 of the LSR to see if there are any errors in the data currently residing in the receive FIFO. Finally, it
will (1) alternately read a data word through the RX FIFO read pointer and the error bits via the MMM LSR until
the FIFO is empty, or (2) read successive data words (knowing there were no errors in the FIFO) until the trigger
count is met.
A similar sequence occurs when data flows in the other direction (from host through transmit FIFO), except there
is no error bit manipulation/checking involved.
FIFO Operation
The 16-byte transmit and receive data FIFOs are enabled by the FIFO Control Register (FCR) bit-0. You can
set the receive trigger level via FCR bits 6/7. The receiver FIFO section includes a time-out function to
ensure data is delivered to the external host. An interrupt is generated whenever the Receive Holding
Register (RHR) has not been read following the loading of a character or the receive trigger level has been
reached.
Receive (RX) FIFO
The RX FIFO can be configured to be 16 words deep and 11 bits wide. Each word in the RX FIFO consists
of 8 data bits and 3 error bits. The RX block of the MMM contains read and write pointers and status flag
circuitry that need only to be presented with data (for input), reset, read/write control signals, and read/write
clock signals. The RX block of the MMM internally manages the FIFO register file and pointers, and it
provides simultaneous read/write capability (no contention problems).
The RX block of the MMM provides data (for output), FIFO full flag, FIFO empty flag, and an almost full flag
which uses an associated predefined trigger level (obtained from the MMM FCR control register) to signal
when the trigger level has been met. Four possible trigger levels may be selected by programming bits 6-7
of the FCR control register.
Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342I)
81
Chapter 3 – SocketModem (MT9234SMI)
A typical (interrupt driven) write to the RX block is a two-step process. The MMM micro-controller must first
write the 3 error bits to a shadow MMM LSR status register. Next, the micro-controller writes the data to the
RX FIFO and during this write operation, the 3 error bits are directly loaded from the LSR shadow register
into the bits 8-10 of the selected (11 bit-wide) FIFO register. These error bits represent the parity error,
framing error, and break interrupt signals associated with each data work transmission into the receive
FIFO. When the receive FIFO is read, these error bits are loaded directly into bits 2-4 of the MMM LSR
register.

Time Out Interrupts
The interrupts are enabled by IER bits 0-3. Care must be taken when handling these interrupts. Following a
reset the transmitter interrupt is enabled, the SocketModem will issue an interrupt to indicate that transmit
holding register is empty. This interrupt must be serviced prior to continuing operations.
The LSR register provides the current singular highest priority interrupt only. A condition can exist where a
higher priority interrupt may mask the lower priority interrupt(s). Only after servicing the higher pending
interrupt will the lower priority interrupt(s) be reflected in the status register. Servicing the interrupt without
investigating further interrupt conditions can result in data errors. When two interrupt conditions have the
same priority, it is important to service these interrupts correctly.
Receive Data Ready and Receive Time Out have the same interrupt priority (when enabled by IER bit-3).
The receiver issues an interrupt after the number of characters received have reached the programmed
trigger level. In this case the MMM FIFO may hold more characters than the programmed trigger level.
Following the removal of a data byte, the user should recheck LSR bit-0 for additional characters. A Receive
Time Out will not occur if the receive FIFO is empty. The time out counter is reset at the center of each stop
bit received or each time the receive holding register (RHR) is read.

RBR – Receive Buffer (RX FIFO)
All eight bits are used for receive channel data (host read/data in; host write/data out). The three error bits per
byte are copied into bits 2, 3, and 4 of the LSR during each host I/O read; therefore, they are available for
monitoring on a per-byte basis.
THR – Transmit Holding Register (TX FIFO)
All eight bits are used for transmit channel data (host write/data out; host read/data in).
IER – Interrupt Enable
Bits 4–7: Reserved and will always read 0.
Bits 0-3: Set by host software only and cleared by software control or host reset.
Bit 3:
Enables modem status IRQ. If bits 0–3 of the MSR are set and this bit is set to 1 (enabled), a host
interrupt is generated.
Bit 2:
Enables receive line status IRQ. If bits 1–4 (overrun, parity, framing, break errors) of the LSR are set
and this bit is set to a logic 1, a host interrupt is generated.
Bit 1:
Enables transmit holding register IRQ. If bit 5 (transmit holding register empty) of the LSR is set and
this bit is set to a 1, a host interrupt is generated.
Bit 0:
Enables received data available IRQ. If bit 0 (data ready) of the LSR is set and this bit is set to a 1, a
host interrupt is generated.
IIR – Interrupt Identification (Read Only)
Bits 6–7: (FIFO enabled bits). These bits will read a 1 if FIFO mode is enabled and the 16450 enable bit is 0
(no force of 16450 mode).
Bits 4–5: Reserved and always read a 0.
Bits 1–3: Interrupt ID bits.
Bit 0:
Interrupt pending. If logic 0 (in default mode), an interrupt is pending.
When the host accesses IIR, the contents of the register are frozen. Any new interrupts will be recorded, but not
acknowledged during the IIR access. This requires buffering bits (0–3, 6–7) during IIR reads.

When bit 3 is a 1, it enables a multiple byte (FIFO mode) data transfer.
TX FIFO reset. This will cause TX FIFO pointer logic to be reset (any data in TX FIFO will be lost).
This bit is self clearing; however, a shadow bit exists that is cleared only when read by the host, thus
allowing the host to monitor a FIFO reset.
RX FIFO reset. This will cause RX FIFO pointer logic to be reset (any data in RX FIFO will be lost).
This bit is self clearing; however, a shadow bit exists that is cleared only when read by the host, thus
allowing the host to monitor a FIFO reset.
FIFO enable. The host writes this bit to logic 1 to put the block in FIFO mode. This bit must be a 1
when writing other bits in this register or they will not be programmed. When this bit changes state,
any data in the FIFOs or the RBR and THR registers will be lost and any pending interrupts are
cleared.

LCR – Line Control
Divisor latch access bit. This bit allows the host, access to the divisor latch. Under normal
circumstances, the bit is set to 0 (provides access to the RX and TX FIFOs at address 0). If the
bit is set to 1, access to transmitter, receiver, interrupt enable, and modem control registers is
disabled. In this case, when an access is made to address 0, the divisor latch least (DLL)
significant byte is accessed. Address 1 accesses the most significant byte (DLM). Address 7
accesses the DLX divisor latch register. Address 4 accesses the MCX status/control register.
Bit 6:
Used to denote a host-generated set break condition.
Bits 0,1,3,4,5: Used only in parity bit generation for the 7 bit data byte case. Bits 0 and 1 are used for word
length select (b0 = 0 and b1 = 1 is used for 7 bit data). Bit 3 is parity enable. Bit 4 is even parity
select. Bit 5 is stick parity.
Bit 7:
MCR – Modem Control
Bits 5–7:
Bit 4:
Bit 3:
Bits 0–2:
Bit 2:
Bit 1:
Bit 0:
Reserved, and will always be 0.
Used for loopback. When a 1, bits 0–3 of the MCR are reflected in modem status register (MSR)
as follows: RI <= OUT1, DCD <= OUT2, DSR <= DTR, CTS <= RTS. Emulation of loopback
feature of 16550 UART must be done by the host except for the above conditions. Also, when
this bit is set, it allows for data loop back. This means the host can write a data word to the TX
and immediately read back the same data word from the RX (in a manner similar to the 16550A).
Controls the signal used to 3-state the host interrupt. If 0, then an active-low L33xV output will be
set to 0, and this signal will be used to 3-state the host interrupt output pin.
Used during LOOP function.
OUT1.
Request to Send (RTS).
Data terminal ready (DTR).

LSR – Line Status
Bit 7:
Bit 6:
Bit 5:
Bits 2–4:
Bit 1:
Bit 0:
Error in RX FIFO. This bit is always set to 1 if at least one data byte in the RX FIFO has an error.
This will clear when there are no more errors in the RX FIFO.
Transmitter empty. This bit is the same as LSR bit 5 (THRE) in MMM
Transmitter holding register empty. This bit is set to 1 when either the transmitter holding register
has been read (emptied) by the micro-controller (16450 mode) or the TX FIFO is empty (16550
mode). This bit is set to 0 when either the THR or the TX FIFO becomes not empty in 16450
mode. In 16550 mode, it is set to 0 only after the trigger level has been met since the last
occurrence of TX FIFO empty. If the transmitter timer is enabled, a shadow bit exists which
delays the timer setting this bit to 1. When reading this bit, the micro-controller will not see the
delay. Both shadow and register bits are cleared when the host writes to the THR or TX FIFO in
16450 mode. The trigger level must be reached to clear the bit in 16550 (FIFO) mode.
Used for parity error, framing error, and break detect. These bits are written, indirectly, by the
micro-controller as follows: The bits are first written to the shadow bit locations when the microcontroller write accesses the LSR. When the next character is written to the receive buffer (RBR)
or the RX FIFO, the data in the shadow bits is then copied to the RBR (16450 mode) or RX FIFO
(16550 mode). In FIFO mode, bits become available to the host when the data byte associated
with the bits is next to be read. In FIFO mode, with successive reads of the receiver, the status
bits will be set if an error occurs on any byte. Once the micro-controller writes to the RBR or RX
FIFO, the shadow bits are auto cleared. The register bits are updated with each host read.
Overrun error. This bit is set if the micro-controller makes a second write to RBR before the host
reads data in the buffer (16450 mode) or with a full RX FIFO (16550 mode). No data will be
transferred to the RX FIFO under these circumstances. This bit is reset when the host reads the
LSR.
Data ready bit. This bit is set to 1 when received data is available, either in the RX FIFO (16550
mode) or the RBR (16450 mode). This bit is set immediately upon the micro-controller writing
data to the RBR or FIFO if the receive timer is not enabled, but it is delayed by the timer interval
if the receive timer is enabled. For micro-controller read access, a shadow bit exists so that the
micro-controller does not see the delay that the host sees. Both bits are cleared to logic 0
immediately upon reading all data in either RBR or RX FIFO.
MSR – Modem Status
Bits 4 through 7 of the MSR can also take on the MCR bits 0 through 3 value when in MCR loop mode (i.e. when
MCR b4 = 1). The transfer of bits in loop back has a null modem twist (i.e. MCR b0 goes to MSR b5 and MCR
b1goes to MSR b4).
Bit 7:
Data carrier detect (DCD) bit.
Bit 6:
Ring indicator (RI) bit.
Bit 5:
Data set ready (DSR) bit.
Bit 4:
Clear to send (CTS) bit.
Bit 3:
Delta data carrier detect pin. This bit is set to a 1 whenever the data carrier detect bit changes
state. It is reset when the host reads the modem status register.
Bit 2:
Trailing edge ring indicator bit. This bit is set to 1 on the falling edge of the ring indicator bit. It is

SCR – Scratch
The host programmer uses this register for temporary data storage.
DLL – Divisor Latch (LSByte)
This register contains low-order byte for the 16-bit clock divider. It is kept to maintain register set compatibility with the
16C550A interface. However, it is not used for clock generation since MMM does not require the generation of a real
baud clock.
DLM – Divisor Latch (MSByte)
This register contains high-order byte for the 16-bit clock divider. It is kept to maintain register set compatibility with
the 16C550A interface. However, it is not used for clock generation, since MMM does not require the generation of a
real baud clock.
Programming the Baud Rate Generator Registers DLM (MSB) and DLL (LSB) provides a user capability for selecting
the desired final baud rate. The example in the Table below shows the selectable baud rates available when using a
1.8432 MHz external clock input.

Chapter 4 – SocketModem (MT2492SMI)
Introduction
The Multi-Tech SocketModem MT2492SMI-xx utilizes the LSI CVxx Controller Based Modem Devices and the LSI CSP104
Silicon Direct Access Arrangement (DAA) to form a 2-chip complete embedded modem. This solution includes a DSP data
pump, modem controller, on-chip RAM and ROM, codec, DAA, analog output, and 24.576 MHz clock input.
The modem accepts standard modem AT commands and provides connect rates up to 56 Kbps full-duplex over the Public
Switched Telephone Network (PSTN) and features a complete set of modem protocols including all ITU-T standard formats up
to V.92.
To provide the most flexibility, the CVxx modem system-side device provides numerous additional features for embedded
modem applications. It includes call progress monitoring through standard result codes, error correction, data compression,
autobaud, and fast connect modes. In addition, because the CVxx modem integrates the DAA, analog features (such as line-in
use and over current detection) are included.
This device is ideal for embedded modem applications due to its simple host interface, small board space, and low power
consumption.

Provisioning a Generic SocketModem CDMA
The Difference Between a Pre-Provisioned SocketModem CDMA and a Generic
SocketModem CDMA
Pre-Provisioned SocketModem CDMA
Multi-Tech offers several pre-provisioned SocketModem CDMA units (see the Product Ordering Information table
at the beginning of this chapter). Pre-provisioned SocketModem CDMA builds are pre-programmed to operate
only on a designated CDMA carrier’s network; for example, the MTSMC-C-N2 is pre-programmed (provisioned)
for use on the Sprint network in the USA.
Generic SocketModem CDMA
Multi-Tech also offers two generic SocketModem CDMA models, the MTSMC-C-N1 (Random A-Key) and
MTSMC-C-N9 (Zero A-Key). These generic SocketModems are not pre-programmed to operate on any
designated CDMA carrier’s network.
Overview of the Provisioning Process
Requirements
•
A generic SocketModem CDMA-C-N1 or -N9.
•
AT Commands Reference Guide for the SocketModem CDMA, Chapter 16.
•
A developer software tool called WPST.
Procedures
Step 1. Get the PRI and PRL from your wireless carrier.
Step 2. Set the provisioning commands, which are described in the AT Commands Reference Guide for
the SocketModem CDMA, Chapter 16, using the provisioning information provided by the CDMA
wireless network carrier.
Step 3. Using the WPST tool, download the carrier’s specific PRI (Provisioning Information) and PRL
(Preferred Roaming List) into the SocketModem CDMA.
The wireless modem is now provisioned and can be activated on your wireless carrier’s network, according
to the carrier’s activation instructions.
See the Activation directions that accompany Multi-Tech wireless modems.
Provisioning Terminology
A-Key
The A-Key is a 64-bit cryptographic key variable stored in the semi-permanent memory of the mobile station
and also known to the Authentication Center of the wireless carrier's system. The generation of the A-Key is
the responsibility of the wireless service provider. It is established and entered when the mobile station is
first put into service.
The CDMA network carrier you choose for you SocketModem CDMA product will let you know whether it
uses the Random A-Key or the Zero A-Key in its authentication process. That will determine whether you
purchase the -N1 or the –N9 build.
Provisioning
Provisioning is the programming of a SocketModem CDMA wireless modem to set the PRI and PRL
provided by wireless network carrier that you are have chosen as your CDMA wireless network carrier. After
the modem is provisioned, it can then be activated on the wireless network for which it is provisioned. MultiTech provides two SocketModems CDMA builds that are not pre-provisioned: MTSMC-C-N1 and MTCAB-CN9.
PRI stands for Provisioning Information. Provisioning Information is your wireless
network carrier’s profile of parameter settings that must be programmed into your
wireless modem in order for it to operate on the carrier’s wireless network.
PRL stands for Preferred Roaming List. The PRL is a list of the wireless network service
provider’s preferred roaming partners. This list is downloaded from your network service
provider during the provisioning process.

capacity and high-speed data rates. It is backward compatible with IS-95B and IS-95A.
cdma2000 1xRTT "1xRTT" stands for 1 times Radio Transmission Technology and is used to identify the version of
CDMA2000 radio technology that operates in a pair of 1.25-MHz radio channels (one times 1.25
MHz, as opposed to three times 1.25 MHz in 3xRTT). Although theoretically capable of higher data
rates, most carrier implementations have limited the peak data rate to 144 kbit/s. While 1xRTT
officially qualifies as 3G technology, 1xRTT is considered by some to be a 2.5G.
ESN
"ESN" stands for Electronic Serial Number. It is a 32-bit binary number that identifies each cellular
phone.
Handset (Path) Handset (Path). This is the audio path (microphone & speaker) that connects to a traditional hand
held telephone receiver, usually dual balanced electrical lines.

Chapter 11 – SocketModem HSDPA
Operating Modes
The table below briefly summarizes the various operating modes.
Mode
Function
Normal
operation
GSM / GPRS / UMTS /
HSDPA SLEEP (for USB
only)
GSM IDLE
GSM TALK
GPRS IDLE
Power saving mode set automatically when no call is in progress and the
USB connection is suspended by host or not present.
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
SocketModem is ready to send and receive.
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.
The SocketModem 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
The SocketModem 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 11 – SocketModem HSDPA
Turn off the SocketModem Using AT Command
The best and safest approach to powering down is to issue the AT^SMSO command. This procedure lets the SocketModem
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 is one way to verify that the SocketModem turns off:
Wait for the ”OK” – response. It indicates that data has been stored non-volatile and that the SocketModem turns after
about one second.
Important Note: The SocketModem requires a reset to become active again.
Automatic Shutdown
Automatic shutdown takes effect if:
•
The modem exceeds the critical limits of overtemperature or undertemperature.
The board temperature is constantly monitored by an internal NTC resistor. The values detected by the NTC resistor
are measured directly on the board and are therefore not fully identical with the ambient temperature.
Each time the board temperature goes out of range or back to normal, the modem instantly displays an alert (if
enabled).
ƒ
URCs indicating the level "1" or "-1" allow the user to take appropriate precautions, such as protecting the
SocketModem from exposure to extreme conditions. The presentation of the URCs depends on the settings
selected with the AT^SCTM write command:
AT^SCTM=1: Presentation of URCs is always enabled.
AT^SCTM=0 (default): Presentation of URCs is enabled for 15 seconds time after startup. After 15
seconds operation, the presentation will be disabled, i.e. no alert messages can be generated.
ƒ
URCs indicating the level "2" or "-2" are instantly followed by an orderly shutdown, except in cases of
temperature control during an emergency call (see paragraph below). The presentation of these URCs is always
enabled; i.e., they will be output even though the factory setting AT^SCTM=0 was never changed.
Temperature-Dependent Alerts
Sending temperature alert (15s after start-up; otherwise, only if URC presentation enabled)
^SCTM_B: 1
Caution: SocketModem close to over-temperature limit.
^SCTM_B: -1
Caution: SocketModem close to under-temperature limit.
^SCTM_B: 0
SocketModem back to uncritical temperature range.
Automatic shutdown (URC appears no matter whether or not presentation was enabled)
^SCTM_B: 2
Alert: SocketModem is above over-temperature limit and switches off.
^SCTM_B: -2
Alert: SocketModem is below under-temperature limit and switches off.
Notes:
•
The MTSMC-H will not transmit temperature URC alerts.
•
The URCs will not display in data mode.
Temperature Control during an Emergency Call
If the temperature limit is exceeded while an emergency call is in progress the engine continues to measure the temperature,
but deactivates the shutdown functionality. If the temperature is still out of range when the call ends, the SocketModem
switches off immediately (without another alert message).
Power Saving
The modem is able to reduce its functionality to a minimum (during the so-called SLEEP mode) in order to minimize its current
consumption. The following sections explain the SocketModem’s network dependant power saving behavior.
The implementation of the USB host interface also influences the SocketModem’s power saving behavior and therefore its
current consumption. During normal WCDMA operation; i.e., the modem is connected to a WCDMA network, the duration of a
power-saving period varies. It may be calculated using the following formula:
t = 2DRX value * 10 ms (WCDMA frame duration).
Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342I)
150
Chapter 11 – SocketModem HSDPA
Power Saving While Attached to GSM Networks
The power saving possibilities while attached to a GSM network depend on the paging timing cycle of the base station.
The duration of a power saving interval can be calculated using the following formula:
t = 4.615 ms (TDMA frame duration) * 51 (number of frames) * DRX value.
DRX (Discontinuous Reception) is a value from 2 to 9, resulting in paging intervals between 0.47 and 2.12 seconds. The
DRX value of the base station is assigned by the GSM network operator.
In the pauses between listening to paging messages, the SocketModem resumes power saving, as shown in the figure
below.
Power Saving and Paging in GSM Networks
The varying pauses explain the different potential for power saving. The longer the pause the less power is consumed.
Generally, power saving depends on the SocketModem’s application scenario and may differ from the above mentioned
normal operation. The power saving interval may be shorter than 0.47 seconds or longer than 2.12 seconds.
Power Saving While Attached to WCDMA Networks
The power saving possibilities while attached to a WCDMA network depend on the paging timing cycle of the base
station.
During normal WCDMA operation, i.e., the SocketModem is connected to a WCDMA network, the duration of a power
saving period varies. It may be calculated using the following formula:
t = 2DRX value * 10 ms (WCDMA frame duration).
DRX (Discontinuous Reception) in WCDMA networks is a value between 6 and 9, thus resulting in power saving intervals
between 0.64 and 5.12 seconds. The DRX value of the base station is assigned by the WCDMA network operator.
In the pauses between listening to paging messages, the SocketModem resumes power saving, as shown in the figure
below.
Power Saving and Paging in WCDMA Networks
The varying pauses explain the different potential for power saving. The longer the pause the less power is consumed.
Generally, power saving depends on the SocketModem’s application scenario and may differ from the above mentioned
normal operation. The power saving interval may be shorter than 0.64 seconds or longer than 5.12 seconds.
Power Saving During Network Search, GSM/WCDMA
The power saving interval during network search depends on the network registration mode configured for the modem.
This mode can be specified with the AT^SCFG command parameter MEopMode/RM:
•
In "Fast" mode, the power saving interval may last for up to 5 seconds.
•
In "Normal" mode, the power saving interval may last for up to 40 seconds.
For details on how to configure the AT^SCFG parameter MEopMode/RM see the HSDPA AT Command Guide.

Chapter 11 – SocketModem HSDPA
Interface Signal Descriptions
USB Interface
The SocketModem supports a USB 2.0 Full Speed (12Mbit/s) device interface. A USB host has to support at
least 6 ‘Message Pipes” to work with the HSPDA USB interface.
The USB I/O-pins are capable of driving the signal at min 3.0V. They are 5V I/O compliant.
The USB interface is powered by VUSB. VUSB must be supplied by USB host in the range 4.5 to 5.25V. The
maximum load in VUSB is 10mA.
While the USB connection is active, the SocketModem will not change into SLEEP Mode. To enable switching
into SLEEP mode the USB host must bring its USB interface into Suspend state. On incoming calls, the
SocketModem will then generate a remote wake up request to resume the USB connection.
Note: The MTSMC-H will not transition to sleep mode.

Regulatory Requirements for the Antenna
This section covers how to use the modular transmitter in order to maintain the modular transmitter approval and RF
exposure compliance.
Conditions to Satisfy Modular Transmitter Approval
This device is intended only for use by OEM integrators under the following 3 conditions:
1. The antenna must be installed such that 20 cm is maintained between the antenna and the end user for
all installations.
2. The transmitter module may not be located with any other transmitter or antenna.
3. The communications device is approved using the FCC "unlicensed modular transmitter approval"
method. Therefore, the communication device must only be used with the originally approved antennas.
As long as the 3 conditions above are met, further transmitter testing will not be required. However, the OEM
integrator is still responsible for testing their end-product for any additional compliance requirements with this
communication device installed (for example, digital device emissions, PC peripheral requirements, etc.)
IMPORTANT NOTE: In the event that any of these conditions CANNOT be met (for example certain laptop
configurations, location with another transmitter, or use of a different type antenna), then the FCC authorization
for the communications device is no longer considered valid and the FCC ID CANNOT be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.
RF Exposure Statements Developers Must Include in the User Manual for End Users
The user manual for consumers must include the following information in a prominent location:
IMPORTANT NOTE: To comply with FCC RF safety exposure limits, the antenna used for this transmitter must
be installed to provide a separation distance of at least 20 cm from all persons and must not be located or
operating in conjunction with any other antenna or transmitter.
Regulatory Requirements for End Product Labeling
Suggested End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be installed in such a way
that 20 cm may be maintained between the antenna and the users (for example access points, routers, wireless
ASDL modems, and similar equipment). The final end product must be labeled in a visible area on the exterior of
the enclosure with the following or similar text: "Contains TX FCC ID: AU792U07B06821".
FCC & IC Information to Consumers
The user manual for the consumer must contain the statements required by the following FCC and IC
regulations: 47 C.F.R. 15.19(a)(3), 15.21, 15.101 and RSS-Gen Issue 2 dated June 2007, Sections 7.1.4 and
7.1.5.
Additional Information That Must be Provided to OEM
Integrators
The end user should NOT be provided any instructions on how to remove or install the modular transmitter.

Chapter 13 – SocketWireless Bluetooth
(MTS2BTSMI)
Introduction
The Multi-Tech Systems, Inc. SocketWireless with Bluetooth-enabled technology allows developers to establish wireless
networks using a special set of AT commands. The SocketWireless with Bluetooth technology makes the cable-replacement
transition to wireless networks seamless and easy.
This chapter explains how to establish Bluetooth communication between two serial devices for data applications in a point-topoint network. Bluetooth-enabled devices create communication-ready devices by integrating data functionality into a single,
universal socket design. This complete, ready-to-integrate device dramatically reduces development time and costs for system
designers.
Notes about Byte Gaps and Data Latency
Because of the way Bluetooth is designed and operates, random byte gaps of 5 ms to 20 ms are common. Packet size
will vary from transmission to transmission.
Although the serial bandwidth operates up to 920K bps, effective data throughput in fast streaming mode is
approximately 200K bps. Effective data throughput in regular data mode is 60K bps. The reason for the slower speed in
regular mode is due to the AT parser, which looks at each character for ASCII valid command scripts in the regular
mode's data stream.
The SocketWireless RX has very limited buffering, so if you do not use hardware flow control and are transmitting
further distances, you will quickly overflow the 50 byte buffer because of RF retransmissions, etc.
When a Bluetooth connection is made, the SocketWireless device goes into regular data mode per the power-up factory
default settings. This enables the user to configure the SocketWireless settings remotely via a remote RF Bluetooth
connection. Basically, you can setup the SocketWireless device so no commands are required to be sent from the
embedded side of the device. This allows seamless interfacing with legacy systems without the need to modify the host
device

Note: When sending commands from the Slave when the Slave connects in Fast Data Mode (ATSW25/or issuing
ATMF). All valid AT commands are sent through the Slaves UART will be interpreted and responded by the Master
radio as if it was the local Slave radio. Basically in this configuration from the Slave end you can obtain status and
configure from the remote Master radio. This is a unique feature that may be useful in some applications but can
confuse the user if you think you are talking to the local Slave UART.
To Get Out of Data Mode and Check Status:
1.
Delay at least 50 milliseconds; this could be less or more.

Repeater Example Using the SocketWireless MTS2BTSMI or the Bluetooth Adapter MT2BTA.
Changing Configuration
Parameters, such as the Bluetooth Name, Service Name, Class of Device, and Serial Port settings can be viewed
and configured. This can be done locally through the serial port UART or from a remote Bluetooth RF link. To
configure the SocketWireless Bluetooth device, the device must be in command mode by issuing +++.
You can use the developer board and the RS-232 cable to connect to a PC and pass ASCII characters through the
terminal to the SocketWireless Bluetooth device. The communications settings should match the settings used when
the SocketWireless Bluetooth device connects. For example, the defaults are:
9600bps
8 bits
No Parity
1 stop bit
Hardware flow control enabled.
Once you change these parameters, you have the option to store them permanently in the non-volatile memory. Run
your favorite terminal emulator, HyperTerminal, or other program.
•
Type AT on your screen and follow it with a carriage return <cr_lf>. You should see "OK" returned to you.
This will verify that your cable and communications settings are correct. When the SocketWireless device is
not connected to another Bluetooth device, you can type the AT commands directly into the SocketWireless'
UART; e.g., you do not have to type +++ to change from data mode to command mode.
•
Now you can enter any of the AT commands discussed in the following sections. Follow these commands by
<cr_lf>. Valid commands will return an "OK" or a valid response. Invalid commands will reply ERROR.
•
To return to data mode, type ATMD. You can now pass or receive data from a remote connected Bluetooth
device.
Notes:
•
If you change communications parameter settings, remember to change your terminal or emulator
communications settings to correspond to the newly created parameter settings.
•
AT commands will not echo back to the terminal.
