CHAPTER 1: INTRODUCTION

This chapter discusses the basic operating features of the 7400B
Plus and describes the external indicators and connectors.

The 7400B Plus is a new version of the 7400B Data Module. It is
fully compatible with the 7400B and supports all of its
functionality and applications. In addition, the 7400B Plus has the
following benefits:

d

the ability to dial voice calls from your terminal device, and

d

enhanced support for calls that utilize higher speed modems
(9600 V.32 modems) in a modem pool.

OVERVIEW Congratulations on the addition of the AT&T 7400B Plus.

ffffffffffffffffffffffffffffffffffffffffffff

Following our tradition of excellent quality and high reliability,
we have designed this new 7400B Plus with the latest advances in
telecommunications technology.

The 7400B Plus is a full-duplex asynchronous, Hayes Compatible
data module. It provides integrated voice-data communications
at the desktop over standard twisted pair wiring. At the desk, the
7400B Plus provides asynchronous communication speeds
ranging from 300 bps to 19.2 Kbps. The 7400B Plus’s ability to
emulate Hayes compatible modems, makes it compatible with the
many standard PC communications packages that use Hayes
Command sets. In addition, the 7400B Plus provides a voice dial
capability that allows you to initiate voice calls from a PC using
industry standard "auto-dialer" PC communications packages.

The 7400B Plus is a data service link between a Data Terminal
Equipment (DTE) device and the following AT&T digital PBX
equipment:

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

FEATURES A terminal device is connected to the 7400B Plus through a

standard EIA-232-D interface (formerly called the RS-232-C), and
a Digital Communications Protocol (DCP) interface (using a type
D8W modular telephone cord) is used to connect the 7400B Plus to
the digital PBX.

An internal DIP-switch allows the 7400B Plus to be optioned for
use either with or without a telephone. In the stand-alone case,
the 7400B Plus supports data service only, otherwise, the 7400B
Plus provides simultaneous data and voice service. The 7400B
Plus will work with all of the 7400 series DCP voice terminals in
providing simultaneous data and voice service.

The voice dial feature allows you to dial a voice call without
touching the telephone, and depending on the communications
package, you can store telephone numbers on a PC and recall
them for dialing, log phone calls for easy billing, and take notes
for later reference during a telephone conversation.

In addition, the 7400B Plus can be used to automatically turn on
the speakerphone of the voice terminal when a voice call is dialed
from your terminal device. The 7400B Plus voice dial feature can
be used with all DCP voice terminals, except for the following:

d

7403D (all models)

d

7404D (all models)

d

7405D (all models)

d

7407D01A

Note: If a 7400 series voice terminal with data features is used

with the 7400B Plus, data service is provided by the 7400B
Plus and the data features of the voice terminal cannot be
used.

About the Terminal Device The 7400B Plus operates with any asynchronous data terminal

device that has an EIA-232-D (or RS-232-C) interface. If you are
using a PC as your terminal, you will need a suitable PC
communications package. EIA-232-D cables and PC
communications packages are described in the following
paragraphs.

You must set the appropriate configuration options before
connecting the 7400B Plus to a printer or plotter. To do this,
connect a data terminal or PC to Port 1 of the 7400B Plus, change
and store the necessary configuration parameters, remove the data
terminal or PC, and then connect the printer or plotter. The
configuration parameters used for this type of operation are
described in the section, Remote Site Use in Chapter 3,
"Configuration and Operation."

Selecting an EIA-232-D
Cable

Select an EIA-232-D with a male connector at one end to connect
with the Port 1 connector of the 7400B Plus, and a connector of the
appropriate ‘‘gender’’ at the other end to connect to the
communications port of your terminal device.

Note: Cables with the earlier RS-232-C designation will also

work.

The most common EIA-232-D cables are supplied with a male
connector at both ends. If you have this type of cable and the
EIA-232-D port on your terminal device is a male connector, you
can use a cable adapter commonly referred to as a ‘‘gender
changer’’. Otherwise, obtain an EIA-232-D cable that has the
appropriate gender connector at each end to fit your application
needs.

ffffffffffffffffffffffffffffffffffffffffffff

Selecting DCP Cords The 7400B Plus is supplied with a 7-foot D8W cord. Use this, or

obtain the appropriate length D8W telephone cord for DCP
connection between the 7400B Plus and the PBX wall jack. If you
are using the with-telephone option, you will need a second D8W
telephone cord to connect between the 7400B Plus and your
telephone or voice terminal.

Selecting PC
Communications Packages

The purpose of PC communications software is to allow your PC
to operate as an asynchronous voice-data communications
terminal. Of the many software packages available, all perform
essentially the same functions, but often in significantly different
ways.

If you do not already have a PC communications package, consult
with an experienced user for advice on selecting software to suit
your voice-data communications needs. The following, though
not required, are a few helpful features that you may wish to look
for in the software you select:

d

Local mode. Also called direct mode, terminal mode, dumb
terminal mode or chat mode, this feature allows you to issue

AT commands to the 7400B Plus to configure its options.

d

Dialing directory. This feature allows you to store several
frequently called numbers, often along with configuration
of the data options needed for completing the connection.

d

Auto-dialer software. This feature allows you to
automate the process of dialing a voice call without
touching the telephone. The following three basic types of
auto-dialer software are available:

Phone Management supports call log and note taking
DOS Utilities typically supports auto-dial capabilities
Personal Information Managers (PIM) supports

automated calendars, databases, time lines, pert charts

d

Predefined data options profiles. Some programs include
completely defined data option profiles (also called
configuration profiles) for popular modems. If available,
select the options profile for the Hayes Smartmodem 2400.

d

Command files. These files, also called script files, allow
you to define a group of commands that may be executed
for automatically logging into specific remote devices.

Chapter 4, "PC Applications," provides guidelines for using a few
of the more popular PC communications packages with the 7400B
Plus.

User´s Guide Page 2-9

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Selecting DIP-Switch
Options

Five options are selected by setting switches on an 8-position
DIP-switch (SW1). These options are described here, and
procedures for setting the switches are provided in the next
section titled "Setting the DIP-Switch Options."

ffffffffffffffffffffffffffffffffffffffffffff

With/Without Telephone Option (SW1-1)

When this option is set for operation without an associated
telephone (SW-1 set to ‘‘ON’’), the 7400B Plus offers only data
service between a terminal device and a remote system. Setting
this option for operation with an associated voice terminal (SW-1
is set to ‘‘OFF’’) enables simultaneous data and voice service over
the same line from the PBX.

When the 7400B Plus is optioned for operation with a telephone, a
7400 series DCP voice terminal must be connected to the 7400B
Plus. Data service is provided directly from the 7400B Plus, and
any data features that the voice terminal may offer cannot be
used.

Note: A change in the setting of this option becomes effective

when the 7400B Plus is powered on after being powered
off. The setting of this option cannot be changed
arbitrarily—it must agree with how the PBX line is
administered. Check with your telecommunications
manager to administer the line for simultaneous voice
and data or data service required.

CHAPTER 2: INSTALLATION DEFINITY Communications System

7400B Plus Data Module

Page 2-10 User´s Guide

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Data Metering Option (SW1-5)

When the data metering option is disabled (SW1-5 set to ‘‘OFF’’),
the transfer speed of the 7400B Plus will adjust to match the
transfer speed of the remote system. The CONNECT xxxx
message is displayed when a connection is completed.

When this option is enabled (SW1-5 set to ‘‘ON’’), it allows the
user to set-up a call to a remote end that is running at a slower
speed than the local data module. (This allows the user to
communicate with a slower speed device without lowering the
speed of the terminal). The CONNECT xxxx message will always
indicate the speed of the local data transfer. The 7400B Plus
performs the speed conversion and uses the CTS lead to flow­control the user’s terminal if it is sending too much data too fast.
During the data transfer, the DATA METERING LED indicates the
state of the CTS lead.

Note: If you are using a PC with a communications package, or

a dedicated terminal that does not support CTS control,
you cannot make file transfers with the data metering
option enabled.

A change in the setting of this option becomes effective
immediately when the 7400B Plus is in the idle mode or as soon as
it is returned to the idle mode. The 7400B Plus is in idle mode any
time that it is not in test mode or connected to an active data call.

Suppress Touch-Tone/Dial-Tone (SW1-6)

This option is only valid if the speakerphone enable/disable
option is set to enable. This option applies only to voice dial calls,
and is only valid when the Speakerphone enable/disable option
(SW1-7) is set to enable. When the option is disabled (SW1-6 set to
‘‘OFF’’), the speakerphone (if available) is activated before dialing,
allowing the user to hear the dial-tone and touch-tones. When the
switch is enabled (SW1-6 set to ‘‘ON’’), the speakerphone is
activated after dialing, allowing the user to hear the far-end
ringing and answer.

Speakerphone Disable/Enable Option (SW1-7)

This option applies only to voice dial calls. When the
speakerphone option is enabled (SW1-7 set to ‘‘OFF’’), the
speakerphone is turned on automatically when you use your
terminal to dial a voice call. If you want to disable the automatic
speakerphone feature, disable the speakerphone option (SW1-7 set
to ‘‘ON’’). This option will have no effect if the voice terminal
does not have a speakerphone.

Note: When SW1-6 and SW1-7 are set to ‘‘OFF’’, the 7400B Plus

automatically activates the speakerphone at the beginning
of the voice call so you can hear dial-tone and touch­tones. When SW1-6 is set to ‘‘ON’’ and SW1-7 is set to
‘‘OFF’’, the activation of the speakerphone is delayed
until dialing is complete.

Make Busy on Local Loop Option (SW1-8)

HARDWARE
INSTALLATION

This option controls the make-busy feature of the 7400B Plus.
When the option is enabled (SW1-8 set to ‘‘ON’’), the 7400B Plus
will busyout the DCP line when either the Local Loopback or
Local Loopback/Self-Test mode is entered. The busyout
condition is released when the test ends.

Note: A change in the setting of this option becomes effective

immediately when the 7400B Plus is in the idle mode or as
soon as it is returned to the idle mode. The 7400B Plus is
in idle mode any time that it is not connected to an active

INITIAL SYSTEM CHECKS This section describes procedures for initially checking out your

hardware and any required software. It is assumed at this point
that your hardware and PC communications package have been
properly installed and are ready for use.

Note: PC communications software is required only if you are

using a PC as your terminal device. A dedicated data
terminal does not need PC communications software.

Power-Up Self-Test When power is first applied to the 7400B Plus, the unit performs a

self-test to determine that it is in working order. The progression
of the self-test is indicated by the sequential, left-to-right lighting
of the 10 front-panel LEDs.

When the self-test completes, the LEDs labeled POWER/TEST and
TR will remain lit and all other LED lamps will go out.

Note: The operation of the LEDs described here assumes that

the factory-default options are still in effect. Once certain
options have been changed, the operation of the LEDs
may differ from this description.

Your 7400B Plus is now installed and ready for data
communications operation.

ffffffffffffffffffffffffffffffffffffffffffff

IF YOU ARE USING A PC PC communications packages provide the capability of

configuring the 7400B Plus automatically. When using a PC
communications package with the 7400B Plus, there are two items
to note:

1 The PC communications package should be configured to

work with a Hayes Smartmodem 2400 or Hayes compatible
modem.

ffffffffffffffffffffffffffffffffffffffffffff

2 The dialing method of the PC communications package

should be set to Tone for data calls, and Pulse for voice calls.

Many PC communications packages provide the possibility of
writing script or command files. These files can then be run to
execute a sequence of commands that will configure your system,
or even provide an automatic log on procedure for a particular
remote end device. Review the documentation for your PC and
PC communications package. Once you understand the PC
communications package well enough, you will be ready to begin
using it with the 7400B Plus.

Since there is such a diversity of functionality among the many PC
communications packages available, refer to the user’s manual of
the package for specific details of its use. Chapter 4, "PC
Applications" provides guidelines for using a few of the more
popular packages with the 7400B Plus.

For more information about the ‘‘AT’’ interface and operation of
the 7400B Plus, refer to Chapter 3, "Configuration and Operation."

IF YOU ARE USING A
DEDICATED TERMINAL

ffffffffffffffffffffffffffffffffffffffffffff

When a dedicated terminal is used with a 7400B Plus, you must
control the operation of the 7400B Plus. In a way, you are acting
as a PC communication package. To do this, you must
understand the operation of the 7400B Plus. Refer to Chapter 3,
"Configuration and Operation."

CHAPTER 3: CONFIGURATION AND OPERATION

This chapter describes how to change, store, and recall
configuration parameters, outlines how to create and save custom
configuration profiles, and discusses more advanced command
usage with example command lines.

This chapter also provides some basics on the 7400B Plus
operation, describes how to use a few ‘‘AT’’ commands that are
essential for most voice-data communications operations, and
then outlines a typical
on-line session.

Note: The commands for the 7400B Plus are referred to as ‘‘AT’’

commands because you must type the letters AT as the
first characters on the line for most commands.

OPERATING MODES Except when a test condition has been initiated, the 7400B Plus is

ffffffffffffffffffffffffffffffffffffffffffff

always in one of two states: command mode or data mode. When
power is first applied, the 7400B Plus initializes to command
mode.

In command mode, the 7400B Plus looks at everything you type
on your keyboard. When you type in something that the 7400B
Plus recognizes as a valid command with a valid parameter (if
required), it will execute the action requested. A valid command
with an invalid parameter will produce the ERROR result code.
An invalid command will also produce the ERROR result code,
and is ignored.

In data mode, everything you type is passed as data without
interpretation by the 7400B Plus, except the escape sequence. The
escape sequence, described in later paragraphs, provides a way of
switching the 7400B Plus back to command mode without
disconnecting a data call.

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

ISSUING COMMANDS The following paragraphs describe the elements of a command

line and how the 7400B Plus responds to a command line when it
is issued.

AT Command Line Prefix All commands issued to the 7400B Plus must begin with the letters

ffffffffffffffffffffffffffffffffffffffffffff

‘‘AT’’ or ‘‘at’’ with the exception of the ‘‘A/’’ command which is
discussed later. The command line prefix must be entered as
either both uppercase or both lowercase letters (that is, at and
AT will work, but aT and At will not).

The letters ‘‘AT,’’ also known as the ATtention command, alerts
the 7400B Plus to expect one or more commands to follow. The
7400B Plus examines the command line prefix to determine the
communications rate of the terminal equipment as well as its
parity setting. The 7400B Plus automatically adjusts the speed
and parity settings and uses the setting until another ‘‘AT’’
command is received, or until the 7400B Plus is powered down.

Formats supported by the 7400B Plus are shown in Table 3-1.

TABLE 3-1

CHARACTER FORMATS

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Data Bits Parity Stop Bits

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

7 even or odd 1
7 mark or space 1
8 none 1

All of these parameters may be changed on the local terminal
device as needed. The 7400B Plus will adjust to match the speed
and parity of the local terminal device when it receives an ‘‘AT’’
command.

If you connect to a remote system and your screen shows a
series of nonsense characters (also referred to as ‘‘garbage’’),
chances are that you need to adjust the speed or parity on the
terminal to match the settings of the 7400B Plus.

character buffer. The AT prefix, spaces, and the
end of the command line are not saved and do not add to the
character count. If you try to type more than 40 countable
characters on one line, the result code ERROR will be displayed on
your terminal screen, and the command line will be ignored.

as soon as you enter the AT prefix, the 7400B Plus immediately
reads it and sets up for a command to follow. Hence, you cannot

backspace character is an ASCII backspace.

Once you complete a command line by pressing
7400B Plus will try to interpret all characters on the command line
as valid commands. If the 7400B Plus finds a character that is not
a valid command, it will ignore the erroneous character and any
remaining characters on the command line.

Acknowledgement

Commands are acted upon immediately and are acknowledged by
a result code. Most commands are acknowledged by OK. This
assumes that the result codes are configured in the verbose form
(command V1 is in effect), and are enabled (Q0 in effect).
Another option for configuring result codes is the short or
numeric form. These result codes are set by the V0 command
which would produce a 0 (zero) instead of the message OK. A
final option for result codes is to configure them for visible
acknowledgement (Q1). Refer to Appendix A, "AT Command Set"
for descriptions of the V and Q commands.

CONFIGURATION
PARAMETERS

Parameter Storage and
Retrieval

Values for configuration parameters are selected by using ‘‘AT’’
commands. For a description of ‘‘AT’’ commands used by the
7400B Plus, refer to Appendix A, "AT Command Set."

ffffffffffffffffffffffffffffffffffffffffffff

Configuration parameter values include the option values selected
by ‘‘AT’’ commands that require option values, and the values
stored in the S-registers. A set of configuration parameter values
is called a profile. The 7400B Plus has four configuration profiles
at any given time, one active, two stored, and one that
permanently contains the factory-default values.

Unsaved changes to configuration parameters remain in effect
until they are changed again, or until the 7400B Plus is
disconnected from the AC power source. Before making or
storing any changes, or to check changes that you have made, you
can issue an ‘‘AT’’ command to view the values that are currently
in the active profile and the two stored profiles.

The active profile contains the parameter values that are currently
in effect. All parameter values can be changed, and most changes
can be stored to one of the two profile storage locations by issuing
an ‘‘AT’’ command. Another ‘‘AT’’ command recalls values from
one of the two stored profiles into the active profile.

Factory-default parameter values are a selection of values that are
appropriate for a wide number of applications. These values are
stored permanently in ROM and you can issue an ‘‘AT’’ command
to recall them into the active profile at any time.

DATA OPERATION This section provides information on how to use the 7400B Plus

for data calls.

From Data Mode to
Command Mode and Back

An escape sequence, +++, can be typed at any time during a data call
to return temporarily to command mode. Your call does not
disconnect, but data is not exchanged. Once you have ‘‘escaped’’
to command mode, the 7400B Plus returns OK to acknowledge
that it has entered command mode (see section titled ‘‘Command
Acknowledgement’’).

At this point, you can issue commands to the 7400B Plus. As long
as the data call has not been disconnected, you can use the ‘‘ato’’
command to return to data mode.

One other condition will cause the 7400B Plus to switch from data
mode to command mode. If the PBX senses that the remote
device has disconnected, it will disconnect the call to the 7400B
Plus. The 7400B Plus will turn off the CD, OH, and DATA LEDs,
display a result code message on your terminal screen (such as
NO CARRIER), and then return to command mode.

The escape sequence and all other commands discussed in this
section are explained in Appendix A, "AT Commands."

ffffffffffffffffffffffffffffffffffffffffffff

Dialing a Data Call The dial command is issued to the 7400B Plus in the form

atdtnnn...n, where d is the dial command, t is the dial modifier
(see "Appendix B" for more information on dial modifiers), and
nnn...n represents the number you wish to dial. The command line
can hold up to 40 characters, so you can usually precede the d
with other commands on the same line.

ffffffffffffffffffffffffffffffffffffffffffff

The following is an example:

Enter

atdt74768

In the example, the command will cause the 7400B Plus to go off
hook, dial the number, and then wait the period of time specified
in S-register S7 for the call to be completed.

If the call can not be completed, the 7400B Plus may disconnect
and send the result code NO CARRIER or BUSY to your display
screen. When a call is successfully completed, the 7400B Plus will
send the result code CONNECT nnnn to your screen, where nnnn

Storing a Telephone
Number

The 7400B Plus is capable of storing up to four telephone
numbers, each of which can contain up to 25 characters. Numbers
stored in this way remain available indefinitely, even after the
7400B Plus has been powered off and then on again.

Table 3-4 describes the command lines used to store a telephone
number, delete a number from storage, and dial a stored number.

Note: Digits 0 through 9 and all letters ‘‘a’’ through ‘‘z’’ and

‘‘A’’ through ‘‘Z’’ may be part of the stored ‘‘number.’’
Spaces and hyphens (-) may be used in the number when
typing the command line. Spaces are not stored and do
not add to the total count of characters in the stored
number, but all other ASCII characters are stored and
counted. Any ASCII character may be used, as long as it
is acceptable to the PBX. A semi-colon (;) character
cannot be stored because it is used to delimit the end of
the string being stored so that additional commands can
be entered on the same command line.

where nnn is a decimal number in the range of 1 through 255,
representing the number of rings to wait before answering. If nnn
is 0 (the factory-default setting), the automatic answer feature is
turned off. The red LED on the front of the 7400B Plus labeled
‘‘AA’’ lights when the automatic feature is turned on.

Remote Site Use The 7400B Plus can be used at a remote site as a dedicated service

device to answer incoming data calls, send data to a remote end
device, and then hang up. For example, you may wish to provide
access to a printer from a remote site.

The following is a typical command line you might use for setting
up this operation (spaces are used here for readability, but are not
required):

Enter

AT &F &C1 &D2 E0 Q1 S0=1 &W0 &Y0

(

fffffffbbbbbbb

Following the AT prefix, the commands in the example produce
the following results:

d

&F resets the options to the factory defaults.

d

&C1 sets the Data Carrier Detect (DCD) circuit of the 7400B
Plus to operate according to the EIA standard.

d

&D2 sets the 7400B Plus to go on hook when an on-to-off
transition is detected on the Data Terminal Ready (DTR) input,
disconnecting the call

)

d

E0 turns off the echo.

d

Q1 turns off the result codes that would be the normal
responses of the 7400B Plus to commands that it receives. (For
example, the ‘‘CONNECT’’ message which is displayed when
answering a call would interfere with the printer.)

d

S0=1 turns on the automatic answer feature and causes the
7400B Plus to answer an incoming data call on the first ring.

d

&W0 causes the current configuration to be stored in data
profile storage location 0.

d

&Y0 selects the configuration stored in data profile storage
location 0 to become the current configuration each time the
7400B Plus is powered on

Reset and Configuration
Recall

Two commands are available for recovering from various data
communications problems. You can reset the 7400B Plus and
recall one of two stored profiles as the current configuration. The
form for this command is as follows:

atzn

(

fffffffbbbbbbb

)

Enter

where n is the number 0 or 1, representing the configuration
profile to be recalled.

A second command allows you to recall the factory-default
configuration if, for instance, you loose track of changes you have
made and need to start over. The form for this command is as
follows:

at&f

(

A Sample On-Line Session This section outlines how to perform a simple on-line session

using the ‘‘AT’’ commands described in this chapter. For more
information about all ‘‘AT’’ commands, see Chapter 3,
"Configuration and Operation" and Appendix A, "AT Command
Set."

ffffffffffffffffffffffffffffffffffffffffffff

Starting the Session

The following is a sample data call to a fictitious bulletin board
service. If you know the number of a ‘‘real’’ bulletin board
service, you might try an actual log on by using that number and
following the suggestions in this session.

Enter

at d 9-555-7575

CONNECT 1200

The D command is used to dial the number of the bulletin board.
Since the connection was made successfully, the 7400B Plus
responded with a message that says the remote end connected
and the data speed to be used is 1200 bps.

(

fffffffbbbbbbb

)

The remote end may do nothing until you press a particular key a

Enter

few times, usually
communications application programs, this sometimes required
input lets the remote end determine whether you have connected
with the correct communications parameters in effect.

(

fffffffbbbbbbb

)

. Typical of many data

ffffffffffffffffffffffffffffffffffffffffffff

Possible Display Problems

If the response from the remote end is unintelligible ‘‘garbage,’’
chances are that the speed or parity bit selection is incorrect. In
this case, assuming that your terminal device allows, the
parameters may be corrected without disconnecting the call.
Otherwise, you must disconnect, correct the parameters, and then
try the call again.

Another possible problem is that the remote end response
contains normal words mixed in with strange characters, many of
which are left brackets ([). This usually indicates that the remote
device is sending ANSI display control sequences, and your
terminal does not recognize them (ANSI stands for American
National Standards Institute).

On a PC, this can generally be remedied by first disconnecting the
call, editing the PC’s CONFIG.SYS file to include the line

DEVICE=ANSI.SYS

rebooting the PC, and then trying the call again. (For a log off
procedure, see the alternative method under ‘‘Disconnecting a
Data Call,’’ below.)

DEFINITY Communications System CHAPTER 3: CONFIGURATION AND OPERATION
7400B Plus Data Module
User´s Guide Page 3-17

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Note: If the terminal device is not a PC, or the suggested

remedy does not seem to solve the problem, you will need
to consult the documentation for your dedicated terminal,
or for your PC and any software involved.

ffffffffffffffffffffffffffffffffffffffffffff

Disconnecting a Data Call

Most remote systems will have a command or menu selection for
logging off. When you select the appropriate means, the remote
system will disconnect or hang up. The PBX will disconnect the
call and, after a moment, the 7400B Plus will send the following
message to your display:

NO CARRIER

Alternatively, you can use the following disconnect procedure:

Selection: +++
OK

The prompt Selection: is simply a representation of how the remote
system might ask you for your next command or menu selection.
Type the escape sequence (default is +++) but do not press

Enter

(

fffffffbbbbbbb

pause again after typing +++.) When the 7400B Plus responds
with OK, type the command line:

The PBX will disconnect from the remote end device, and the
7400B Plus will send the OK message to the terminal display.

)

. (Pause before typing +++, type +++ quickly, and then

Enter

VOICE OPERATIONS This section provides information on how to use the 7400B Plus

for voice dialing.

Using the 7400B Plus for
Voice Dialing

The 7400B Plus is equipped with a voice dial feature which allows
you to place voice telephone calls from the attached terminal
device. To place a voice call, just tell the 7400B Plus to use pulse
dialing by including the ‘‘P’’ dial modifier. (For data calls, tell it to
use tone dialing by including the ‘‘T’’ dial modifier.) If you fail to
specify the type of dialing to be used for a call, a data call will be
made.

If you have a speakerphone, the 7400B Plus will normally turn it
on when a voice call is being dialed. You may option the 7400B
Plus to inhibit the speakerphone or delay activating it until after
dialing is complete by setting the appropriate DIP switches. For
more information on DIP switches, see Chapter 2, "Installation."

If your telephone does not have a speakerphone, you may lift the
handset at any time.

Voice calls can be originated from the PC, but you must use the
telephone to hang-up a call.

ffffffffffffffffffffffffffffffffffffffffffff

Dialing Instructions When a voice call is made using the PC, the telephone number

should be given to the 7400B Plus in a single ‘‘AT’’ dial command
as indicated in the example below.

ffffffffffffffffffffffffffffffffffffffffffff

ATD P 9,1 [phone]

The ‘‘P’’ dial modifier must be included to tell the 7400B Plus that
the call is a voice call. If an attempt to dial a voice call is made
using more than one dial command on a command line, the first
dial command will be accepted and the second dial command
may be discarded. After dialing the call, the 7400B Plus
automatically returns to the command mode.

A second voice call can be made from your PC by manually
placing the first call on HOLD, and then entering a dial command
for the second call. Any attempt to dial a second voice call while
the first call is being dialed will be ignored.

Note: On DEFINITY Communications Generic 1, System 75,

if you are in directory mode on the telephone, the
procedures are ignored.

On DEFINITY Communications Generic 2, System 85,
after you have manually placed the first call on HOLD,
you must select a second call appearance before entering
a dial command for the second call.

DEFINITY Communications System CHAPTER 3: CONFIGURATION AND OPERATION
7400B Plus Data Module
User´s Guide Page 3-19

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Dialing Delay To ensure that dialing does not begin before dial tone is received,

dialing a voice call will be delayed by the time stored in the S6
register (Wait Time Before Blind Dialing register) and can be set to
a maximum value of 255 seconds. The factory setting of 2 seconds
for S6 is adequate for most calls and should not be changed.

Dialing Pause A pause for second dial tone is normally required for calls outside

the PBX. This can be provided by including a comma between the
outside line prefix (for example, 9) and the first digit of the
telephone number to be dialed. The comma instructs the 7400B
Plus, after dialing the prefix number, to pause a fixed time before
dialing the first digit of the telephone number. The pause time is
stored in the S8 register (Duration of Delay For Comma Dial
Modifier) and can be set for any value up to a maximum of 255
seconds. The factory setting of 2 seconds is adequate for most
applications and it should not be changed. If added delay is
required, additional commas can be added to the number.

CHAPTER 4: PC APPLICATIONS

This chapter provides information that describes how to configure
some popular data and voice PC communications packages for
use with the 7400B Plus.

Some of the functions and features mentioned in this chapter may
not be available to you depending on the version of the software
that you are using.

DATA CALL NOTES The 7400B Plus has been tested with a variety of communications

packages for use with DOS and Macintosh PCs.
To dial a data call, the modem configuration must be set to TONE

(T) dialing. If given a choice, set the modem type to Hayes 2400
Smartmodem or just Hayes.

These software packages were tested with the 7400B Plus at a rate
of 2400. Check with your System 75/85 administrator to
determine the appropriate baud rate to use on your system.

When you are placing a call, if the Carrier Detect lamp is on and
your computer cannot communicate with the far end, check to
make sure that you have set the appropriate communication
parameters for that service.

ffffffffffffffffffffffffffffffffffffffffffff

VOICE DIALING NOTES The 7400B Plus voice dialing feature has been tested with the

following PC Communication Packages:

d

Hot Line V2.2

d

SideKick V1.5 and SideKick Plus V1.0

d

PC Tools V6

For PC communication packages to dial voice calls, the modem
configuration must be set to PULSE (P) dialing (even though the
7400B Plus will use Touch-Tone). If given a choice, set modem
type to Hayes 2400 Smartmodem or just Hayes.

ffffffffffffffffffffffffffffffffffffffffffff

Note: While the 7400B Plus supports simultaneous voice and

data, the above packages support alternate voice/data
DIALING only. It is possible to dial a voice call with a
data call on hold, but the above voice dialing packages
interfere with data operation, by remapping the COM
port or by hanging up the data call.

You can dial a data call while on a voice call. In all cases, the
linked telephone will work.
