Section One: Introduction
The V.34 Boca Office Communicator offers the latest in modem
technology, featuring voice, fax, and data communications. This
versatile Plug-and-Play compatible modem allows you to establish
a structured set of mailboxes. Now, you have an all-in-one
communications product that serves as answering machine, voice
mailbox, and fax machine.
Voice Capabilities
The Office Communicator features automatic call recognition, autodial and auto-answer, an internal speaker, and embedded voice
modem ‘AT’ command set. The modem, along with its host
computer, support answering machine functions through voice and
fax communications software. You can set up multiple mailboxes.
The automated attendant feature allows dial-in users to skip
between mailboxes, then check, answer, and leave messages. The
FDVSP34I and FDV34SVD models come with full-duplex
speakerphone and echo cancellation.
Fax Capabilities
The Office Communicator offers a wide range of fax services. It
supports Group 3, class 1 and 2 fax send and receive operations. It
complies with ITU-TSS (formerly CCITT) V.17, V.29, V.27ter, and
V.21 channel 2 international fax standards. It also implements the
EIA T-30 protocol.
Data Capabilities
The Office Communicator offers the widest possible range of
internationally accepted standard modulation methods and protocols.
The modem complies with ITU-TSS standards V.34, V.32bis, V.32, V.23,
V.34 Boca Office Communicator
13
V.22bis, V.22, and V.21, as well as Bell 212A and 103. The modem
implements V.42 error control with LAP-M and MNP 2-4, as well as
data compression with V.42bis and MNP-5.
Ideal for Travelers
Voice features allow for remote call-in with full services to answer,
route, delete, or forward messages. For example, while you are
traveling, faxes are stored on your hard drive. When you call in to
review a voice message, a fax forwarding function allows received
faxes to be forwarded to another fax number at any location.
VoiceView® Support
This standard allows the transmission of computer data to be
introduced during a normal phone call. It alternates between voice
and data—once the data goes through, you automatically switch
back to your voice conversation.
A Word about Digital Simultaneous Voice and Data (DSVD)
Digital Simultaneous Voice and Data (DSVD) is a standard
allowing the simultaneous transmission of voice and data over a
single telephone line. If you have the FDV34SVD model, you will
be able to make ordinary phone calls to other PC users while
sharing modem applications over a standard telephone line. When
a phone call is in Digital SVD mode, any data (e.g., images, 3Dgraphics, shared applications, interactive games) can be shared
with a normal phone conversation over the same analog line.
IMPORTANT: When you use the Boca V.34 Office communicator in DSVD mode,
you need to add the following command to your initialization string:
AT-SSE=1
Note that while the modem is in DSVD mode, full-duplex speakerphone reverts
to half-duplex functionality.

2.5 Optional Accessories
The V.34 Boca Office Communicator is equipped with
microphone and speaker jacks for use with headset, speakers and
microphone. (See installation instructions on pages 17-18). The
microphone can be used to record outbound messages. These
messages can also be recorded with a telephone attached to the
modem. However, a microphone is recommended for better
quality recordings. You may use a combination headphone and
microphone or a separate microphone and speaker(s).
Microphone Requirements:
The microphone element must be of the electret type also known
(incorrectly) as a condenser type. The microphone in most
telephone handsets is of this type. The V.34 Boca Office
Communicator was designed for a microphone sensitivity of -64
dBspl.
Other microphone sensitivities work equally well, with only a
subjective difference in loudness. Carbon microphone elements
will also work, but don’t offer the quality of the electret. Another
common microphone element is the dynamic type which will
NOT work with the V.34 Boca Office Communicator
Speaker Requirements:
You can attach the V.34 Boca Office Communicator to a highquality external speaker or the earpiece of a handset. The external
speaker must have an impedance rating of 8 ohms or more.

Should terminal equipment or protective circuitry cause harm to the telephone
network, the telephone company shall, where practical, notify the customer
that temporary discontinuance of service may be required; however, where
prior notices are not practical, the telephone company may temporarily
discontinue service if such action is deemed reasonable in the circumstances.
In the case of such temporary discontinuance, the telephone company shall
promptly notify customers and will be given the right to bring a complaint to
the FCC if they feel the disconnection is not warranted.
Compliance Information

Changes in Telephone Company Equipment or Facilities
The telephone company may make changes in its communications
facilities, equipment, operations, or procedures, where such action is
reasonably required and proper in its business. Should any such changes
render the customer’s terminal equipment incompatible with the
telephone company facilities, the customer shall be given adequate
notice to make modifications to maintain uninterrupted service.
General
The FCC prohibits customer-provided terminal equipment be connected
to party lines or to be used in conjunction with coin telephone service.
Installation
The modem is equipped with a USOC RJ-11 standard miniature
modular jack and is designed to plug directly into a modular jack.
DOC Compliance Statement (Canada)
The Canadian Department of Communications label identifies certified
equipment. This certification means that the equipment meets certain
telecommunications network protective operational and safety
requirements. The Department does not guarantee the equipment will
operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is
permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed
using an acceptable method of connection. In some cases, the
company’s inside wiring associated with a single line individual service
may be extended by means of a certified connector assembly (telephone
extension cord). The customer should be aware that compliance with the
above conditions may not prevent degradation of service in some
situations.
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any repairs
V.34 Boca Office Communicator
33
or alterations made by the user to this equipment, or equipment
malfunction, may give the telecommunications company cause to
request the user to disconnect the equipment.
Users should ensure, for their own protection, that the electrical ground
connections of the power utility, telephone lines, and internal metallic
water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
CAUTION Users should not attempt to make such connections
themselves, but should contact the appropriate electric inspection
authority or electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which is
used by the device to prevent overloading. The termination on a loop
may consist of any combination of devices subject only to the
requirement that the total of the load numbers of all the devices does not
exceed 100. The Load number appears on the underside of the modem.

S-Registers
This section defines the purpose of the modem registers, and sequentially
lists the registers and describes their functions. These registers affect
various operating characteristics and allow you to obtain information
about the modem, as well as test the modem. Each register has a factoryset value, which you can read or change to fit your needs.
Reading a Register Value
To read the current value of a register, type:
AT Sn? [ENTER],
where n is a register number.
AT Sn? Sn? [ENTER] from the command mode.
To read the register values of S0 and S1, type
AT S0? S1? [ENTER].
The modem will display the first register value, a carriage return, the
next register value, a carriage return, and OK or 0.
Changing a Register Value
To change a register value, use the Sn command (ATSn=v), where n is a
register number and v is the new value you want to assign to the register.
Type:
AT S0=3 [ENTER]
to have the modem automatically answer on the third ring.
The table on the following page lists the modem’s registers and their
functions.

AT+MS Command (Modulation Select)
This extended format command selects the modulation, optionally
enables or disables automode, and optionally specifies the lowest and
highest connection rates using from one to four subparameters. The
command format is:
+MS=<mod>[,[<automode>][,[<min_rate>][,[<max_rate>]]]]
The default value as reported by the +MS? command is:
+MS=11,1,300,28800
Note 1: For 14400bps and lower speeds, the Nn command and S37
register can alternatively be used, in which case the +MS subparameters
will be modified to reflect the Nn command and S37=x settings. Use of
the Nn and S37=x commands is not recommended, but is provided for
compatibility with existing communication software. (S37 is not updated
by the +MS command).
Note 2: Subparameters not entered (enter a comma only or <CR> to skip
the last subparameter) remain at their current values.
Reporting Selected Options
The modem can send a string of information to the DTE consisting of
selected options: +MS?
The response is:
+MS:<mod>,<automode>,<min_rate>,<max_rate>
Example: +MS: 11, 1, 300, 28800 (shows default values)
Modem Command Reference
50
Reporting Supported Options
The modem can send a string of information to the DTE consisting of
supported options using the following commands.
+MS=?
The response is:
+MS: (list of supported <mod> values), (list of supported <automode>
values), (list of supported <min_rate> values), list of supported <max>
rate values)
Example:
+MS: (0, 1, 2, 3, 9, 10, 11, 64, 69, 74), (0,1) (300-28800), (300-28800)

* For V.23, originating modes transmit at 75bps and receive at 1200bps;
answering modes transmit at 1200bps and receive at 75bps. The rate is
always specified at 1200bps.
The modem may also automatically switch to another modulation
(automode), subject to the following constraints:
• The modem may not be able to automatically switch from the current
modulation (specified by <mod>) to some other modulation. For
example, there is no standard way to automode from Bell 103 to V.23.
• The DTE may disable automode operation (see <automode>).
• The DTE may constrain the range of modulations available by
specifying the lowest and highest rates (see <min_rate> and <max_rate>
below).
Modem Command Reference
52
2. <automode>=an optional numeric value which enables or disables
automatic modulation negotiation. Options are:
<automode> Option Selected
0
Automode disabled
1
Automode enabled
The default value is 1, which enables automode. Note, however, there are
modulations for which there is no automatic negotiation (e.g., Bell 212
(<mod>=69).
For <automode> = 0 (automode disabled, i.e., fixed modulation):
a. If <max_rate> is within the rates supported by the selected
modulation, the selected rate is that specified by <max_rate>.
Example: +MS=9,0,1200,4800 selects V.32 4800bps fixed rate.
b. If <max_rate> is greater than the highest speed supported by the
modulation specified by <mod>, the starting rate is the highest rate
supported by the selected modulation.
Example: +MS=9,0,2400,14400 selects V.32 9600 or 4800bps.
c. To emulate N0S37=x command sequence to select fixed mode
operation, specify the <max_rate> and <min_rate> both to be the same
requested speed, and <mod> to be the modulation for that speed.
Example:
+MS=11,0,16800,16800 selects V.34 16800bps fixed mode
(no comparable S37 command).
+MS=10,0,12000,12000 selects V.32bis 12000bps fixed mode (same as
N0S37=10).
For <automode> = 1 (automode enabled; i.e., automatically selected
speed and modulation).

a. If <max_rate> is greater than the highest rate supported by the
modulation specified by <mod>, the modem automodes down from the
highest rate of selected modulation.
Example: +MS=10,1,1200,24000 selects automoding down from V.32bis
14400bps.
b. To emulate N1S37=x sequence command, specify the modulation and
the rate to start automoding down from using <mod> and <max_rate>,
respectively. Set <min_rate> to 300 to allow automoding all the way
down to V.21 300bps.
Example: +MS=11,1,300,16800 selects automoding down starting at V.34
16800bps (no comparable S37 command)
+MS=10,1,300,12000 selects automoding down starting at V.32bis
12000bps (same as N1S37=10).
3. <min_rate>= is an optional number which specifies the lowest rate at
which the modem may establish a connection. The value is decimalcoded in units of bps, e.g., 2400 specifies the lowest rate to be 2400bps.
The default is 300 for 300 bps.
4. <max_rate>= is an optional number which specifies the highest rate at
which the modem may establish a connection. The value is decimalcoded in units of bps, e.g., 14400 specifies the highest rate to be
14400bps. The default is 28800 for 28800bps.

Appendix D: Glossary
A
algorithm. A formula or procedure which employs various methods
defining how data is to be used to give a prescribed result.
analog signals. Signals which can vary over a continuous range (e.g., the
human voice over conventional telephone lines). Analog circuitry is more
subject to distortion and noise, but it is more capable of handling
complex signals than are digital signals which can have only discrete
values.
ARQ. Automatic ReQuest for retransmission. A type of communications
link where the receiver asks the transmitter to re-send a block of data
when errors are detected.
ANSI. American National Standards Institute. A non-profit, private
industry association which governs most USA-standards setting
agencies.
ASCII. Acronym for American Standard Code for Information
Interchange. ASCII is an ANSI character set. The standard ASCII
character set consists of 128 decimal numbers (0-127) for letters of the
alphabet, numerals, punctuation marks, and common special characters.
The extended ASCII character set extends to 255 characters and contains
special mathematical, graphics, and foreign characters.
asynchronous communications. A method of transmission in which one
character is sent one bit at a time; also referred to as serial transmission.
B
Bell standards. Refers to the U. S. modulation protocol standards
developed by the former AT&T Bell Systems such as Bell 103 (300bps
transmission) and Bell 212A (1200bps transmission).
V.34 Boca Office Communicator
59
bit-mapped registers. An S-register which contains multiple bit-oriented
values.
blind dialing. An automated process whereby the modem goes off-hook
and dials without waiting for a dial tone. This is prohibited in many
countries.
block transfer control. Determines whether or not the modem uses
block or stream mode during an MNP connection. In stream mode, MNP
sends data frames in varying length. Block mode sends fixed data frames
of 256 characters.
bps. bits per second.
break handling. Determines how the modem responds when a BREAK
signal is received from either the DTE (Data Terminal Equipment or
computer/terminal) or the remote modem. This is controlled by the
MNP-based AT extended command \K. A break signal is represented on
the communications line by a steady space signal for a significant length
of time. Break signals may be activated from the keyboard by pressing
the BREAK key or the control (CTRL) and C keys.
C
CCITT. Consultative Committee for International Telephone and
Telegraph. This advisory organization is part of the ITU (International
Telecommunication Union) which is an agency of the United Nations.
Organization recently renamed International Telecommunications
Union-Telecommunications Standard Sector (ITU-T)
command mode. The modem is in command mode when it is turned on
or reset, when it loses its connection to a remote modem, when it is in
on-line mode, or when escape characters (+++) are typed. To transmit
data, the modem must be in data mode. The modem does not transmit
data when in command mode.
communications protocol. A set of procedures which controls how a
data communications network operates.
Glossary
60
D
DCD. Data Carrier Detect. Indicates to the terminal device that the
modem is receiving a valid carrier signal from a remote modem. The
carrier is a tone at a specified frequency.
DCE. Data Communications Equipment. The local and/or remote
modem. A DCE is usually connected to a DTE.
DTE. Data Terminal Equipment. The computer or terminal, either local
(yours), or the remote (the one you’re communicating with). A DTE is
usually connected to a DCE.
DTR. Data Terminal Ready. The computer issues this signal to the
attached modem indicating that it is ready to receive data.
data compression. A technique that examines transmitted data for
redundancy and replaces strings (groups) of characters with special
codes which the receiving modem interprets and restores to its original
form. Transmission of compressed data results in shorter connect times
and hence cost savings for connect charges. Data compression is
sometimes called “source encoding”.
data mode. The modem is in data mode when a connection has been
established with a remote modem and sends a CONNECT response
confirming the connection. User data may then be transmitted or
received.
dial modifier. Dial modifiers are special characters appended to the ATD
command which instruct the modem how to place a call.
digital signal. A discrete signal which can only take on one of several
(usually only two) discrete levels in contrast to analog signals which can
take a continuous range of levels.
V.34 Boca Office Communicator
61
E
error detection and correction. The transmitting modem attaches a
special pattern (called a frame check sequence) calculated according to a
prescribed algorithm from user-defined data to the end of a block of
data. The receiving modem performs the same algorithm and compares
it to the one with the transmitted data. If these match, then the block of
data has been received correctly. If not, the block of data is re-transmitted
until no errors are detected.
escape sequence. Also referred to as the escape command. This special
command is entered as three plus symbols (+++) and places the modem
in command mode and interrupts user data transmission, but does not
terminate the data connection. This allows the entering of commands
while the connection is maintained.
extended AT-command. Extended commands were developed to
provide greater functionality and control over modem operations than is
available from the basic AT command set.
F
fax mode. The modem is in fax mode when, through use of fax
communications software, it can send and receive faxes, print and
display fax files, convert files to fax-files, and set certain fax-related
features. Note: the modulation protocol used by the modem in fax mode
is also different from the usual data mode modulation.
flow control. Compensates for the difference between the rate at which
data reaches a device and the rate at which the device processes and
transmits. The two common types of flow control are RTS/CTS signaling
(a hardware based method, employing an electrical signal) and XON/
XOFF (a software-based method using standard ASCII control characters
to pause or resume transmission). The \G command controls XON/
XOFF flow control.
full-duplex. Two-way simultaneous transmission between modems,
which may occur via a four-wire circuit on a leased line, or with a twowire connection when the frequency bandwidth is divided into two
Glossary
62
distinct channels, or when echo cancellation is employed (e.g., Bell 103,
212, and V.22 use frequency division, while V.32 uses echo cancellation).
G
guard tone. Guard tones are used in the United Kingdom and other
countries. This requires that the modem transmit an 1800-Hz tone after it
sends an answer tone. The guard tone is controlled by the &G command.
Guard tones are not used in the U.S.A.
H
half-duplex. Signal flow in both directions, but only one way at a time
with each modem alternating between send and receive.
Hayes-compatible. Hayes Microcomputer Products, Inc. developed the
AT command set which has become a de facto industry standard. Hayes
commands are always initiated with an AT (attention code) prefix.
hook flash. The dial modifier “!” causes the modem to go on-hook
(hang-up) for one-half second. Also controlled by the ATH command.
L
LAPM. Link Access Protocol Modem. A V.42 ARQ type of error
correction protocol where LAPM may be activated with or without
V.42bis data compression.
leased line. Also referred to as a private line. A leased line is obtained
from a communications company (carrier) to provide a transmission
medium between two points. The line consists of a permanent dedicated
circuit between two points, or to set of previously arranged points. The
cost of the line is usually based on the distance between locations. This is
in contrast to switched or dial-up lines, which can be connected to any
point on the network.
line modulation. The means by which a carrier is varied to represent a
signal carrying information. In a modem, the user’s digital data is used
V.34 Boca Office Communicator
63
to modulate the modem’s transmitter’s carrier or carrier to allow the
digital signal to be carried over analog facilities.
long space disconnect. Determines whether or not modem disconnects
when it receives a continuous break from a remote modem. Controlled
by the ATY command.
loopback tests. There are four types of loopback tests which are as
follows: (1) the local digital loopback tests the operation of the DTE,
including whether or not data is leaving the terminal or computer port;
(2) the local analog loopback tests the digital and analog circuits of the
modem; (3) the remote digital loopback checks the operating condition
of the line and remote modem; (4) the remote analog loopback tests the
line to the remote modem.
M
MNP. Microcom Networking Protocol. A series of data communications
protocols developed by Microcom for full-duplex, error-free
communications.
make/break ratio. The &P command controls the ratio of the off-hook
(make) to on-hook (break) interval used by the modem when it pulse
dials. &P0 selects a 39%/61% make/break ratio for use in the U.S. &P1
selects a 33%/67% make/break ratio for use in the United Kingdom and
Hong Kong. The &P command is NOT allowed in some countries.
modulation handshake. Also referred to as Automode Enable and is
controlled by the ATN command. This determines whether or not the
modem must connect at a particular speed, or allow connection at any
speed supported by both modems.
N
negotiation fallback. Controlled by S-Register 36 as part of the V.42
protocol. Setting this register indicates what action to take when a
desired connection cannot be made (e.g., hang-up, direct mode connect,
normal mode connect).
Glossary
64
non-volatile RAM. Also NVRAM. Random access memory whose data
is retained when power is turned off. This is especially useful for
modems to store user-defined default configuration settings and
frequently used telephone numbers. This information would be loaded
into modem RAM at power-up.
O
on-line state. Same as data mode. To transmit or receive data, the
modem must be in the on-line state. When placing a call, the modem is
put on-line with the dial command.
P
PBX. Private Branch Exchange. A telephone switch at a customer site.
pulse dialing. Also referred to as rotary dialing, i.e., dialing with the
older-style rotary dial wheel. The dial modifier ATDP sets the modem to
pulse dialing, which is the default method as opposed to tone dialing
(push-button touch-tone) which is enabled with ATDT. All telephone
exchanges will accept older-style pulse dialing and most exchanges will
accept modern tone-dialing. Tone dialing is faster and more reliable since
mechanical relays and their inherent failure mechanisms are avoided.
R
result code. A response sent by the modem after executing a command.
The response reports the modem’s status or the progress of a call and can
take the form of either digits (numeric) or words (verbose). Issuing a V1
command enables word responses. A V0 (V-zero) command enables
numeric responses. The Q1 command disables their use entirely.
Example: “OK” (word), or 0 (numeric) indicates that the modem
successfully executed a command.
retrain. An adjustment process performed when one of the modems
detects signal distortion or line noise which threaten data integrity.
V.34 Boca Office Communicator
65
RTS/CTS. Request to Send/Clear to Send. RTS and CTS are two control
signal lines between the modem (DCE) and terminal (DTE) which allow
the terminal to control the flow of information. See also flow control.
S
sleep inactivity timer. Determines the length of time the modem
operates in normal mode with no activity before entering low-power
“sleep” mode.
split-speed direction. Determines which direction (transmit or receive)
has the 75bps channel and which has the 1200bps channel.
standard AT-command. The basic AT command set, originated by Hayes
Microcomputer Products, Inc.
synchronous communications. A method of transmission in which data
bits are sent continuously at the same rate under the control of a fixed
frequency clock signal.
T
touch-tone dialing. Push-button tone dialing as used on contemporary
phone sets. The dial modifier ATDT sets the modem to “tone” mode.
Tone dialing is faster and more reliable than older-style pulse dialing.
trellis coding. A method of modulation which targets specific
modulation points. Signals falling outside of these points are treated as
line noise, thus ensuring greater noise immunity over a given line. QAM
(Quadrature Amplitude Modulation) functions similarly, but has a
broader tolerance and results in lesser noise immunity than trellis coding.
X
XON/XOFF. XON and XOFF are the names of two different flow control
characters. See also flow control.
