The 7400B and 7400B Plus Data 
Module
Figure 21-2. The 7400B Plus Data Module
The 7400B and 7400B Plus Data Modules are full-duplex asynchronous,
Hayes-compatible data modules that provide for simultaneous voice-data
communications at the desk top over standard twisted pair wiring. The 7400B data
module has been discontinued; however, the 7400B Plus data module has all of
the basic characteristics of the 7400B, with the following added benefits:
nSuppor ts the semicolon dial modifier, which enables an automatic return to
the command mode after dialing a data call
nOffers a storable S7 register, which supports increased call set-up time
nOffers the voice dial capability, which provides the ability to dial a voice call
from the PC package in the attached PC
Both of these data modules replace the existing PDM (MPDM) for asynchronous
communication, DTDM, and data stands for 7406D and 7407D voice terminals
(703A DSU and 702AL1) and the 7404D integrated voice/data phone.
NOTE:
If you have a 7400B data module and want to have the voice dial feature,
you can upgrade your current 7400B with a D-kit (Comcode: 106414543)
orderable through the National Par ts Sales Center at 1 800 222-PART.

21-9 The 7400B and 7400B Plus Data Module
21
In the linked mode, the 7400B and 7400B Plus data modules provide for
simultaneous voice data communications over standard twisted pair wiring. In this
mode, the 7400B and 7400B Plus data modules can be used with all DCP voice
terminals to provide data service. The 7400B Plus provides the voice dial feature
for all DCP voice terminals
exceptthe following:
n7403D voice terminal (all models)
n7404D voice terminal (all models)
n7405D voice terminal (all models)
n7407D01A voice terminal
Applications
The 7400B and 7400B Plus data modules can be used with the DEFINITY
Communications System Generic 1, Generic 2, and Generic 3, the DEFINITY
ECS, System 75, and System 85. The data modules are used as a DCE for host
access services, PC, or terminal (DTE) connectivity (see Figure 21-3).
Figure 21-3 shows a diagram of the connections between the 7400B or 7400B
Plus and the data terminal, the digital voice terminal, and the switch.

Features
Lights
nPOWER/TEST light — The red POWER/TEST light goes on when AC
power is supplied to the 7400B or 7400B Plus data module and flashes
during all tests. This light, together with the DATA light, also flashes if there
is a DCP line problem.
nDATA light — The green DATA light goes on during a data call. This light,
together with the POWER/TEST light, flashes if there is a DCP line
problem.
nOther lights — The eight other lights show the RS-232 status information,
the status of two options, and call status information. These lights are red.
Other Physical Features
Jacks
The 7400B and 7400B Plus data modules are equipped with the following jacks:
nPort 1 (RS-232-C or -D)

Capabilities
The 7400B and 7400B Plus data modules have the following basic features and
capabilities:
nDCP mode 2 operation only
nFull-duplex, 10-bit start/stop, asynchronous operation
nAsynchronous data rates of 0.3, 1.2, 2.4, 4.8, 9.6, and 19.2 kbps
nEven, odd, mark, and space parity options
nAutobaud and autoparity
nLinked operation with the associated DCP voice terminal
nData metering — Data metering allows the data module and associated
terminal to operate at higher speeds than the far-end data point.
nSuppor ts the semicolon modifier which enables an automatic return to the
command mode after dialing a data call (for 7400B Plus).
nVoice Dial (for 7400B Plus) — This feature allows you to initiate voice calls
from your PC using the dial command “atdp number.” These calls must be
terminated manually, however.
nSpeakerphone Activation before Dialing (for 7400B Plus) — For terminal
dialed voice calls, you can delay speakerphone activation until after a call is
dialed. You would not hear touch tones or dial tone in this case.
nWait Time for Carrier (for 7400B Plus) — The number stored in the
S7 register establishes the time the 7400B Plus data module will wait for
call set up to be completed. This number can be set for any value up to a
maximum of 255 seconds (with a default to 60 seconds).
Data features for host or terminal applications include:
nEIA RS-232-D DCE interface
nHayes SMARTMODEM 2400™user interface emulation

Power
The stand-alone 7400B and 7400B Plus data modules operate with power from a
WP91508L5 AC power conver ter. This is a modular AC to DC adapter that is
normally plugged into a wall outlet. The data module allows phantom power to be
transmitted to the attached DCP voice terminal even if AC power to the data
module is interrupted.
Setting Options
After removal of the top access panel of the data module during installation, it is
impor tant to verify that the eight option switches are set to provide the desired
features.
nSW1-1—With/Without Telephone Option
This switch must be set to ON for operation
withoutan associated
telephone. This switch must be set to OFF for operation
withan associated
telephone.
nSW1-2 (Not used)
nSW1-3 (Not used)
nSW1-4 (Not used)
nSW1-5—Data Metering Option
When this switch is set to ON, the data module and associated terminal
can operate at higher speeds than the far-end data point. This switch is
usually set to OFF.
nSW1-6—Suppress Touch-Tone/Dial Tone (for 7400B Plus)
Leave this switch set to OFF if the user prefers listening to Touch-Tones as
voice calls are being dialed. Set the switch to ON if the user wants to
suppress Touch-Tones. If the user is using a speakerphone, ringing will be
heard after the call has been made.
nSW1-7—Speakerphone Enable/Disable Option (for 7400B Plus)
Leave this switch set to OFF if the user wants the speakerphone to turn on
automatically when the terminal is used to make a voice call. Set the switch
to ON if there is no speakerphone or if the user wants to disable the
speakerphone automatic activation feature.
nSW1-8—Make Busy on Local Loop Option
This switch should be set to ON if the user wants the telephone line to
appear busy when the local loopback test feature is used to check the
interface between the data module and the terminal.

Notes for Use with PC Packages
The 7400B Plus voice and data feature has been tested with the following PC
communication packages:
nCARBON COPY Plus™ V5.1
nCrosstalk®- XVI V3.71
nCrosstalk Mk.4 V1.1
nHot Line V2.2 (voice dialing packages)
nHyperACCESS®V3.32
nMicroPhone V1.5 (MacIntosh package)
nPC TOOLS Deluxe V6 (voice dialing packages)
nProcomm Plus®V1.1B
nRelay Gold®V3.0
nSideKick®V1.5 and SideKick Plus (voice dialing packages)
nSmar tcom™II V2.2
nSmar tcom II V3.1
nSmar tcom III V1.1
nSmar term 240 V3.0a
nTerra Nova®V1.1.1
nWhite Knight V11 (MacIntosh package)
For those PC packages used to dial voice calls, the modem configuration must be
set to PULSE (P) (even though the 7400B Plus will use Touch-Tone for voice
calls). If given a choice, set modem type to HAYES.
NOTE:
While the 7400B Plus suppor ts simultaneous voice and data, the packages
listed here suppor t
alternate voice/data dialing only. Voice dialing packages
interfere with data operation by remapping the COM port or by hanging up
the data call.
Yo u
candial a data call while on a voice call. In all cases, the linked telephone will
work.
FCC Registration
These data modules are not FCC registered. The 7400B and 7400B Plus data
modules meet Par t 15 Class A requirements and are labeled as such.
