IG6000 User Manual (pdf file, opens new window)

The IG6000 provides a bullet-proof solution where harsh environments are encountered, or where the ultimate in reliability is required. Designed for unattended sites.

The IG6000 has voice message storage in Flash memory, so it can dial out and deliver voice messages in response to control line inputs.
The voice functions are different to the “Voice” (answering machine) functions of most of the commercial modems which do not have Flash message memory. See the section at the end of this page.

Voice Messaging System

This feature can be installed into an IG6000 by downloading a vocabulary
file to the modem to enable it to respond to DTMF tones from a remote modem.

If this feature is enabled by using the #MEM command:
AT#MEM1 Modem will answer in voice mode after S110 rings if DTR is low
AT#MEM2 Modem will answer in voice mode after S110 rings regardless of DTR
AT#MEM0 All voice features off

Dial the modem and wait for it to answer.
After the number of rings specified by S110 (default 4) the modem will answer the call and respond with “Leave a Message after the Beep”.
If you key in a DTMF digit during the time this message is played, the message will stop and you can complete entering the PIN number. The factory default PIN number is 1234. This can be changed by using the new #PIN command.

where nn…nnn is the pin number. Up to 9 digits of PIN number can be specified
If you key in the correct PIN number the modem will say “OK” and ask for a
command. You may key in 0 for a menu of available functions.

Functions Available using DTMF keys
1-20 Play back stored message 1 to 20
*1 Record a new welcome message to replace “Leave a Message
after the Beep” (Press # to finish)
*2 Record a new message (Press # to finish)
*3 Playback the current welcome message
*4 Report number of stored messages and the state of the alarm
switches (ON or OFF)
*5 Play all messages
*6 Enable / disable answering machine record function
*9 Erase stored messages but retain the welcome message
*0 Erase all stored messages including the welcome message
(return to factory default message)
## Hang up

Messages 1 and 2 are used by the alarm switches. Other messages can be
stored and used as a voice mail box which can be shared by a group of people
who know the PIN number.
If no pin number is entered the user can leave a message after the welcome
message beep.

+ To avoid recording a lot of silence the messages can be terminated
with the # DTMF key.
About 8 minutes of voice storage in a maximum of 20 individual messages is available.

How to Load the Voice Alarm Messages

If you have not downloaded a vocabulary file use the following procedure:
1? Connect the modem to a PC running a terminal program (like Hyperterm).
2? Type ATS119=0 to stop modem going to sleep.
3? Type AT#MINI and wait for EPROMs to erase. The modem will beep when ready.
4? Type AT#MEM2 to put the modem into voice answering mode.
5? Connect modem to phone line and using a touch tone phone dial the modem.
The modem will answer with a brief message “Leave a message after the beep!”
6? Record your message into the modem for Alarm Condition #1, leaving 2 seconds
of silence after the beep before speaking.
7? Press the # button on the phone when your message is finished.
8? Hang up the phone wait a few seconds.
9? Ring the modem again and record a second message for Alarm #2
following steps 8 and 9. Your messages are now recorded.
10? Reconnect modem to a terminal program and type AT#MCD to display the
stored messages. The duration of the 2 messages you have recorded should be visible.
11? If you wish the modem to answer calls in data mode type AT#MEM0&W in
a terminal program to turn off the voice answering function or AT#MEM1 if
you want the voice answering function only when DTR is low.
To redo the messages, erase the EPROMs using AT#MINI and record the messages again.

Remote Voice Setting of Alarm Messages

If you have installed the vocabulary file, use the procedure detailed in the
VOICE MESSAGING SYSTEM to enter the modem PIN number then use DTMF command
*2 the record the first message then enter *2 again to enter the second message.
You may playback the messages immediately by keying DTMF 1 and DTMF
2 to verify that they sound OK.
Hang up by keying ##.
