and re-seat it before continuing.  
5.  Replace the cover, the screws and all cords. 
Note:  When additional boards are added you MUST set the jumpers on the new 
board and add the address to the configure file. 
Software Installation 
NOTE:  If your Voice Connection system was purchased with all hardware installed 
then the software has been pre-loaded on the hard drive and this section may be 
skipped.  If you have any questions about the configuration of this software, or wish 
to change it in any way, please read this section first.  ONLY MAKE CHANGES TO 
THE SOFTWARE OR HARDWARE AFTER YOU HAVE READ THIS 
SECTION. 
If you have purchased a software or software and voice board package then you will 
need to install the Voice Connection software on your hard drive.  The software 
installation should only be done after all hardware and voice boards have been 
installed in the computer. 
1.  If the system does not have MS-DOS 6.22 installed then it must be installed 
before proceeding.  Install MS-DOS in a separate directory named DOS.  Please 
refer to the documentation received with your DOS software for proper installation. 
2.  Place the Voice Connection software disk 1 into the floppy drive. 
3.  From the root directory of the C: drive type A:\INSTALL. 
4.  The software will load automatically onto your hard drive.  Follow the prompts 
on the screen and change disks as necessary. 
5.  When all of the disks have been loaded, restart the computer by pressing the reset 
button or turning power off and back on again. 
6.  The system will restart and the main screen of Voice Connection will be 
displayed. 
7.  The database programming may now be entered.

Memory Management 
If you have purchased a turnkey system the memory management software has been 
installed and configured for your system.  You do not need to make ANY changes in 
this configuration.  
If you are purchasing a kit, you must have a 486 or better computer (IBM-
compatible), a minimum of four (4) megabytes of RAM plus one (1) additional 
megabyte for each additional port (i.e., an eight port system would need a minimum 
of eight megabytes), and a hard drive with a minimum of 250 megabytes of free 
space.   
Your Voice Connection software is shipped with a default config.sys and 
autoexec.bat file.  These files will replace your existing config.sys and autoexec.bat 
files when the software is installed.  Your old config.sys and autoexec.bat files are 
renamed to config.old and autoexec.old during the installation process.   
Memory Management Software 
Voice Connection requires a memory management software program to properly 
allocate and manage the expanded memory installed in the computer.  The default 
configuration uses the memory manager included with MS-DOS Version 6.22.  The 
majority of computer systems available on the market should work with this 
configuration.  For increased performance, we recommend the memory management 
software from Quarterdeck Office Systems, Inc.  We have found Qemm386 versions 
6 and up to work very well with Voice Connection. 
Memory Optimization Utilities 
Most memory management software programs include utilities to optimize DOS 
memory.  These programs place certain TSR programs and device drivers into upper 
memory areas, thereby freeing more conventional memory for DOS based 
applications.  Though running these utilities will enhance the performance of your 
Voice Connection system, there are certain precautions that should be taken to 
prevent conflicts.  Listed below are several recommendations for both Microsofts 
memory optimization utility, Memmaker, and Quarterdecks Qemm386 Optimize 
program. 
MemMaker 
1.  Run MemMaker in the custom installation mode. 
2.  Select yes when you are prompted to specify if your programs use expanded 
memory. 
3.  Do not select the High Scan option. 
4.  Do not select the Scan Aggressively option. 
5.  Do not select the Use Monochrome Region option. 
6.  Run the MemMaker program. 
7.  After MemMaker has been run, use the DOS Edit command to view your 
config.sys file.  You will see a line in the file that begins  
 DEVICE=C:\DOS\EMM386.EXE 
 Software Installation  •  7  
						

							 
  MAKE SURE THAT THIS LINE CONTAINS THE PARAMETERS  
 X=D000-DFFF 
  IF THIS PARAMETER IS NOT LISTED, THEN USE THE DOS EDITOR TO 
ENTER IT.  IF THIS LINE CONTAINS THE WORD HIGHSCAN THEN USE 
THE DOS EDITOR TO DELETE THIS WORD. 
8.  Save the changes and exit the DOS editor. 
9.  Restart the computer.  Voice Connection will load.   
10.  If Voice Connection does not start, review step 7, and rerun MemMaker. 
QEMM386 
1. Run the Optimize program.  You may run the program in the express mode. 
2.  Do NOT activate the Stealth option. 
3.  After Optimize has been run, use the DOS edit command to view your config.sys 
file.  You will see a line in the file that begins  
 DEVICE=C:\QEMM\QEMM386.SYS  
 MAKE SURE THAT THIS LINE CONTAINS THE PARAMETERS  
 X=D000-DFFF  NOVIDEOFILL  BIX:Y  BE:N 
 IF THESE PARAMETERS ARE NOT LISTED, USE THE DOS EDITOR TO 
ENTER THEM.  
4.  QEMM386 version 7.X will add the following line to your config.sys file:  
SHELL=C:\QEMM386\Loadhi.com /r:2 /res=XXXX /sqf C:\command.com C:\ 
/P 
or 
SHELL=C:\QEMM386\QEMM386.COM SQUEEZE....etc. 
Remove these lines from your config.sys file if they appear. 
5. Save the changes and exit the DOS editor. 
6. Restart the computer.  Voice Connection will load. 
7. If Voice Connection does not start, review step 3 and rerun Optimize. 
Note:  Any other changes, modification or replacement of the default 
AUTOEXEC.BAT and CONFIG.SYS files that come with Voice Connection will 
result in degraded performance or possibly cause Voice Connection to malfunction 
entirely.  It is recommended that once the above changes have been made and Voice 
Connection is up and running, the startup files be left alone. 
About the use of other utilities 
The installation of other Utility 
programs may void your warranty. Please note that Voice Connection has already provided for disk caching.  Therefore, 
the use of another disk caching utility such as SmartDrive will not only degrade the 
performance of your Voice Connection system but may cause it to become unstable 
under heavy use.  UNDER NO CIRCUMSTANCES CAN ANY DISK 
COMPRESSION PROGRAM SUCH AS DRIVE SPACE BE INSTALLED.

Configuring the Voice Board 
Software 
The Rhetorex voice board supplied with Voice Connection accesses a configuration 
file that defines the port addresses and initialization parameters for all of the boards 
in the system.  This file is automatically installed during the software installation,  
contains default settings and has been programmed for one voice board.  The default 
settings will work with the great majority of telephone systems.  However, some fine 
tuning may be necessary.  This section is intended as a reference when updating is 
necessary.   
Accessing the Configure File 
To load the configure file you must be at the DOS prompt in the Voicecon directory.  
If the Voice Connection system is currently running, exit the program from the File 
option on the main menu bar.  If you are currently at a DOS prompt enter the 
Voicecon directory by typing cd \voicecon. 
  Type configur. 
  The configur program will load and the Main Menu will be displayed. 
Main Menu 
The main menu screen is an informational screen that displays the initialization 
parameters and I/O port addresses for all of the voice boards.  The main menu screen  
is divided into four windows that display information.

SYMBOLS  Displays system resource allocation parameters and channel 
initialization. 
MEMORY  Displays memory allocation assignments. 
FILE  Displays PCPM tone and filter table assignments. 
PORTS  Displays the Rhetorex board port assignments. 
Functions 
A summary of the Main Menu functions is presented below.  The sections that 
follow present each function in detail. 
SYMBOLS  This function allows you to alter system resource assignments and 
channel initialization parameters.  F5 selects the Symbols screen. 
MEMORY  This function allows you to define and edit the memory allocation 
assignments.  F3 selects the Memory screen. 
FILE  This function allows you to define and edit  the PCPM tone and filter table 
assignments.  F4 selects the Port screen. 
VOICE RECOG  This function allows you to define and edit the Voice Recognition 
assignments.  F7 selects the Voice Recognition screen. 
EXIT  The EXIT function terminates the CONFIGUR utility and returns you to the 
DOS command line.  F10 selects the Exit function. 
Before exiting, you are prompted to save the configuration file.  If you respond with 
‘Yes’ the CONFIG file in the current directory is overwritten with the one just made.  
If a CONFIG file does not exist, one is created.  A ‘No’ response returns you to the 
DOS command line without updating the CONFIG file. 
Ports 
 
 
The Rhetorex device driver requires that each Rhetorex board be assigned a unique 
I/O port address and that the address of each board is defined in the CONFIG file.  
The ports function allows you to edit up to 16 Rhetorex I/O port assignments. 
Use the up and down arrow key to position the cursor on a port assignment to edit.  
Enter the hexadecimal I/O port address of the Rhetorex board.  Refer to Assigning 
Port Addresses in the Board installation section for the proper address of each board 
in the Voice Connection system.

Memory 
 
The Rhetorex device driver requires a block of memory in which to build a disk 
buffer pool.  The memory is normally assigned when the driver is loaded.  This 
function allows you to edit the disk buffer memory pool assignment. 
The disk buffer pool should be allocated from EMS memory.  The amount of 
memory assigned to the buffer pool depends on the number of channels configured 
in the system, the speed of the disk subsystem (including caching), the clock rate of 
the CPU and the disk requirements of the application for logging statistics, databases 
accesses, etc. 
The maximum assignable buffer pool is 64K per channel.  Memory allocated from 
EMS memory is assignable in increments of 16K per channel, up to a maximum of 
4096K.  Allowing for increments of 16K times 4 ports would give you this range of 
valid values:  64, 128, 192, or 256.  Example:  For a Four-Port system, at 16K per 
port, the EMS Memory disk buffer pool would be set to a minimum of  64K (4 x 
16K) or a maximum of 256K (4 x 64K).  An Eight-Port system would have valid 
values in the range of 128K to 512K, i.e., 128K, 256K, 384K, or 512K.  Barring 
unusual circumstances, the disk buffer pool  may safely be increased to its 
maximum. 
 Note:  DOS memory should NEVER be allocated for the disk buffer pool.  Leave 
the REALMEMORY=  entry in the Config file defaulted at zero (0). 
Use the up and down arrow key to position the cursor on the memory assignment to 
edit.  Enter the size of the buffer pool in kilobytes (KB).   
File 
The Rhetorex device driver loads with a default PCPM tone and filter table for call 
progress monitoring.  The file function allows you to replace the Rhetorex default 
tables with tables created from the AccuCall utility.  Refer to the section on AccuCall 
or to Appendix C. for details on running the AccuCall program. 
Enter the file name of the Accucall utility tone and filter table.  If the file does not 
reside in the same directory with RHETOREX.EXE and VOICECNF.EXE, be sure 
to specify the full path name. 
Before returning to the Main Menu, this function verifies that the specified file 
exists.  If the file does not exist, a warning message is displayed.  You can override 
the warning message by responding with a Yes at the prompt.

Assigning a tone and filter table file name creates entries in the CONFIG file for the 
symbols TONETABLE=  and FILTERTABLE=. 
Symbols 
The SYMBOLS function allows you to assign system resource allocation parameters 
and channel initialization defaults. 
Resource Allocation 
The Rhetorex device driver (RHETDRV.EXE) requires five resources from the host 
system: 
1.  Hardware interrupt level.  This is assigned by the application during system 
initialization. 
2.  Disk buffer pool.  This is allocated through the MEMORY function. 
3.  I/O port address which is described in the PORTS function. 
4.  One software interrupt. 
5.  4KB of unused address space for shared memory. 
Software Interrupt 
The software interrupt has been assigned in the Voice Connection program as 6e.  
Do NOT change this setting.  Changing this setting will cause Voice Connection 
to malfunction. 
Shared Memory 
The Rhetorex device driver communicates with the voice board through shared or 
dualported memory.  The shared memory is a 4K block of memory that resides on 
the Rhetorex board but appears in the host memory address space. 
By default, the Rhetorex device driver uses address D000:0000.  If this address space 
is not available, assign an alternate address space. 
Move the cursor to the display line that reads: 
 The default RDSP shared memory (DUALPORT) segment is d000:0000 
This creates a CONFIG file entry for the symbol DUALPORT=.  The shared 
memory address is assignable on a 4K boundary between 80000 and  FF000. 
Default Hook State 
By default, the Rhetorex device driver puts all telephone lines onhook when the 
driver is loaded and when the system is halted.  If you want the default state of the 
telephone line to be offhook, position the cursor on the display line that reads. 
 The default telephone line HOOK state is ONHOOK 
Press the spacebar to toggle the state to OFFHOOK.  This sets the CONFIG file 
symbol HOOK=  to OFF.

Automatic Gain Control 
By default, Automatic Gain Control (AGC) is applied to the incoming audio signal.  
If you do not want the incoming signal amplified by the Rhetorex device driver, 
position the cursor on the display line that reads. 
 The default AGC state is ENABLED 
Press the spacebar to toggle the state to DISABLED.  This sets the symbol AGC= to 
DISABLED. 
Bus Mode 
By default the Rhetorex hardware operates in 8-bit AT bus mode.  For compatibility 
with devices that operate in 16-bit bus mode, position the cursor on the display line 
that reads. 
 The default AT bus mode is 8-BIT MODE 
Press the spacebar to toggle the state to 16-BIT MODE. 
Hang-up Detection 
The Rhetorex device driver performs call progress monitoring on outbound 
telephone calls by comparing the detected call progression signals to defined call 
progression tones in the PCPM tone and filter tables.  The Rhetorex device driver 
can perform limited call progress monitoring during record, playback and DTMF 
functions as well.  Normally, call progression signals detected during these functions 
signifies that a caller has disconnected.  Call progression tones that indicate caller 
disconnect are specified as type Terminating in the PCPM tone table. 
By default the Rhetorex device driver looks for terminating type call progression 
signals during record, playback and DTMF functions and terminates the call.  To 
disable this feature, position the cursor on the display line that reads. 
 The default PCPM hang-up detection state is ENABLED 
Press the spacebar to toggle the state to DISABLED.  This sets the symbol 
HANGUP= to DISABLED. 
Whitenoise 
When pause compression is enabled, recorded silence is encoded by a pause 
signature.  During playback, this pause signature is expanded to recreate silence.  By 
default, expanded pause is played as a low level (-42db) of whitenoise.  This 
provides a more natural reproduction of the telephone line.  However, the Rhetorex 
device driver can expand pause as true silence (no signal). 
To expand pause as silence, position the cursor on the display line that reads: 
 The default silence expansion state is WHITENOISE 
Press the spacebar to toggle the state to SILENCE.  This sets WHITENOISE= to 
DISABLED. 
Default Playback Gain 
Normally the Rhetorex device driver plays back signals at the recorded level.  
However, the Rhetorex device driver can amplify the recorded signal to play back 
 Configuring the Voice Board Software  •  13  
						

							 
louder or quieter than the original signal.  The playback level is encoded by a 
number between -8 and 8 where 0 is the normal level, -8 is the quietest level and 8 is 
the loudest level.  The default is 0. 
To change the default playback gain, position the cursor on the display line that 
reads: 
 The default playback gain setting is 0 
Enter a playback level between -8 and 8.  This sets the symbol GAIN= to that 
playback level. 
Default Outdial Mode 
The Rhetorex device driver call progress monitoring can be optimized for detection 
of VOICE or SIGNAL.  Auto attendant and voice mail applications would normally 
optimize for voice.  This provides the quickest detection of call answered.  Random 
outdial applications should optimize for signal.  This provides a longer signal 
analysis interval to allow for a variety of call progression tones on the same call such 
as ringback followed by intercept tones. 
To change the default Rhetorex optimization, position the cursor on the display line 
that reads: 
 The OUTDIAL function is optimized for detection of VOICE 
Press the spacebar to toggle the state to SIGNAL.  This sets the symbol OUTDIAL= 
to SIGNAL. 
When outdial is optimized for voice, then voice on the line can appear as a series of 
spikes, dropouts and frequency shifts during call monitoring.  The call monitoring 
functions use these characteristics to report an answered call. 
Default VOXLIMIT 
VOXLIMIT provides a maximum threshold for undefined cadences.  Call progress 
monitoring continually matches the cadence of the current cycle with previous 
cycles.  If  more than VOXLIMIT number of unmatched cycles are detected, the call 
is presumed answered.  The default value for VOXLIMIT is three. 
To change the default VOXLIMIT, position the cursor on the display line that reads: 
 The default VOXLIMIT IS 3 
Enter a limit value between 1 and 255.  This sets the symbol VOXLIMIT= to that 
limit value. 
Default Spikes 
SPIKES provides a maximum threshold for frequency shifts.  During call 
monitoring, voice sometimes trigger a filter detection.  As more filters are enabled, 
the number of different filter detections increases, without established cadences.  If 
more than SPIKES number of unestablished frequency changes are detected, the call 
is presumed answered.  The default value for SPIKES is six (6). 
To change the default SPIKES, position the cursor on the display line that reads: 
 The default SPIKES is 6 
Enter a limit value between 1 and 255.  This sets the symbol SPIKES = to that limit 
value. 
 Configuring the Voice Board Software  •  14  
						

							 
Default Dropouts 
DROPOUTS provides a maximum threshold for lost cadences.  During call 
monitoring, voice appears as a number of short cadence dropouts (silence intervals) 
on the energy detectors.  If more than DROPOUTS number of lost cadence interval 
are detected, the call is presumed answered.  The default value for DROPOUTS  is 
six (6). 
To change the default DROPOUTS, position the cursor on the display line that reads: 
 The default DROPOUTS is 6 
Enter a limit value between 1 and 255.  This sets the symbol DROPOUTS= to that 
limit value. 
Country Dependent Defaults 
Regulations governing the timing and levels of signaling on telephone lines vary 
from country to country.  This requires different initialization defaults for some of 
the Global Parameters that control signals on the telephone interface. 
The standard Global Parameter defaults are initialized to values for the USA.  To 
change the Global Parameter defaults for the UK or JAPAN, position the cursor on 
the display that reads: 
 The default HOST parameters are initialized for USA 
Press the spacebar to toggle the state to USA, UK, or JAPAN.  This sets the symbol 
HOST=. 
   
Installation with the Telephone 
System 
Voice Connection is designed to work with telephone systems that are capable of 
supporting industry-standard touch-tone telephones (2500 set), such as the ones 
which, more likely than not, are installed in your home.  Incoming lines from the 
telephone company central office may also be plugged directly into the Voice 
Connection system. 
If you are installing Voice Connection with a business telephone system then the 
following conditions must be met: 
1.  The telephone system must be capable of supporting industry standard 2500 
telephones, either directly or through OPX circuits.
