Pan-European Approval
The equipment has been approved in accordance
with Council Decision 98/482/EC for pan-
European single terminal connection to the public
switched telephone network (PSTN). However,
due to differences between the individual PSTNs
provided in different countries, the approval does
not, of itself, give an unconditional assurance of
successful operation on every PSTN network
termination point.
In the event of problems, you should contact your
equipment supplier in the first instance.

All telecommunications devices are required to be
la belled with a Telecommunications Compliance
Label, ensuring their compliance with ACA
Technical Standards. To ensure continuing compli-
ance to A C A Technical Standards, please ensure
the following AT commands are maintained:
ATB0 (ITU/CCITT operation)
AT&G (No Guard tone)
AT&P1 (33/36 pulse dial make/break
ratio)
ATS0=0 (No answer or answer greater
than 1ring) or ATS0>1
ATS6=N (Blind dial delay - acceptable
range is 2-5 seconds)
ATS11=95 (DTMF period between 70-
255ms)

ii
A total of 3 calls attempts are allowed to a
telephone number, with a minimum period
between calls of 2 seconds: if the call doesn‘t
connect after 3 attempts, 30 minutes must expire
before automatic redialling may be initiated.
Failure to set the modem (and any associated
communications software) to the above setting
may result in the modem being non-compliant
with A C A Technical Standards. Under these
circumstance a permit would no longer be valid,
with the user subject to significant penalties under
the Telecommunications Act.
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.
1. While installing the internal modem
card, please ensure there is at least
2mm of air gap between the PCB
card and other components in the
DTE.
2. For Safety reasons, only connect a
Telephone marked with a
Telecommunications Compliance
Label to the phone port.
3. For Safety reasons, only connect

Notice for New Zealand UsersNotice for New Zealand Users
Notice for New Zealand UsersNotice for New Zealand Users
Notice for New Zealand Users
§ The gr ant of a Teleper mit for a device in no
w ay indicates Telecom acceptance of
responsibility for the correct operation of
that device under all operating conditions.
In particular the higher speeds at which
this modem is capable of operating cannot
always be expected on network designed
to delivery voice telephony be customers.
Failure to operate should not be reported
as a f ault to Telecom.
§ In addition to satisfactory line conditions a
modem can only work properly if:
- It is compatible with the modem at the
other end of the call and
- The application using the modem is
compatible with the application at the
other end of the call. E.g. accessing the
Internet requires suitable software in
addition to a modem.
§ This equipment shall not be used in any
manner which could constitute a nuisance
to other Telecom customers.
§ Some parameters required for compliance
with Telecom’s PTC Specifications ar e
iii

dependent on the equipment (PC)
associated with this modem. The
associated equipment shall be set to
operate within the following limits for
compliance with Telecom Specifications:
- Not more than a total of 10 call
attempts shall be made to the same
number for any single manual call
initiation within a 30 minutes period.
- There shall be at least 60 seconds
between call attempts to the same
number.
- Automatic calls to different numbers
shall be not less than 5 seconds apart.
Immediately disconnect this equipment
should it become physically damaged, and
arrange for its disposal repair.
§ The correct settings for use with this
modem in New Zealand are as following:
ATB0 (CCITT operation)
AT&G2 (1800 Hz guard tone)
AT&P1 (Decadic dialling make-
break ratio=33% /67%)
ATS0=0 (not auto answer)
ATS11=65 (DTMF dialling on/off
duration = 65 ms)
ATX2 (dial tone detect, but not
(U.S.A) can progress
detect)
iv

§ When used in the Auto Answer mode, the
S0 register must be set with a value
between 2 and 10. This ensures:
- A person calling your modem will hear
a short burst of ringing before the
modem answers. This confirms that the
call has been successfully switched
through the network.
- Caller identification information (which
occurs between the first and second
ring cadances) is not destroyed.
§ This equipment does not fully meet
Telecom’s impedance r equirements.
Performance limitations may occur when
used in conjunction with some parts of the
network. Telecom will accept no
responsibility should difficulties arise in
such circumstances.
§ It is recommended that this equipment be
disconnected from the Telecom line during
electrical storms.
§ When relocating the equipment, always
disconnect the Telecom line connection
before the power connection, and
reconnect the power first.
Please note that fault callouts caused by
any of the above causes may incur a
char ge from Telecom.
