External Modems & Internal Modem Cards
Modems connected to the Australian telecommunications network must have a valid AUSTEL
permit. This modem has been specifically configured to ensure compliance with AUSTEL
Standards.
Modem Commands:
Command Default Permissible Range
ATB B0 Do not set for Bell mode
AT&G &G2 &G0
AT&P &P1 &P1 only
S Register Default Permissible Range
S0 0 0, 2 to 255
S6 2 2 - 5
S11 95 70 - 255
S45 10 10 - 15
S89 10 10 - 15
AUSTEL Technical Standard 002 Sections 5.3.6.4/5 prescribes how outgoing calls must be made
to avoid contravention of the Telecommunications Act of 1991. Users should be aware that if their
software automatically generates repeat call attempts, they must ensure that no more than 3
repeated call attempts are made to the same number and that there is at least 2 seconds between
each call attempt. If the call sequence is unsuccessful, there shall be a delay of at least 30 minutes
before attempting to call that number again. Failure to observe this requirement would be in
contravention of the approval for connection to the PSTN.
NOTE - This modem has been set up with a factory default of ATX4. This setting enables the
detection of service tones (such as “busy”).
Failure to set the modem or any application software used with the modem to the values shown
above will result in the modem being operated in a non-compliant manner. Consequently, there
would be no permit in force for this modem and the Telecommunications Act of 1991 prescribes a
penalty of $12,000 for the connection of non permitted equipment.
Internal Modem Cards
This modem requires power supply voltages of -5V DC, +5V DC and +12V DC. The modem is
intended for use with a computer expansion connector supplying -5V @ 20mA, +5V @ 300mA and
+12V @ 35mA.
WARNING: The user must make sure that their host equipment is capable of supplying the
additional power required by this card and any other cards that may be connected at the same
time.
The modem card must only be used in a data terminal equipment (DTE) e.g., computer, that has a
screw down cover/lid. As unsafe voltages (TNV) exist on the modem card, disconnect the modem
card from the telephone line while the cover (lid) of the DTE (computer) is removed.
Installation of the modem card into a DTE (computer) which does not require a tool to open the
cover (lid) will render the permit void.
Ensure that the modem card is installed in the host in such a manner that with the exception of the
connections to the host there is a minimum of 2mm air gap between the modem card and other
components in the DTE.
