TECRA A3/S2 xv
Notes for use of this device in New Zealand
■ The grant of a Telepermit for a device in no way 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 depend on a specific network
implementation which is only one of many ways of delivering high quality
voice telephony to customers. Failure to operate should not be reported
as a fault to Telecom.
■ In addition to satisfactory line conditions a modem can only work properly
if:
a/ it is compatible with the modem at the other end of the call and
b/ 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 are 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:
a/ There shall be no more than 10 call attempts to the same number
within any 30 minute period for any single manual call initiation, and
b/ The equipment shall go on-hook for a period of not less than 30
seconds between the end of one attempt and the beginning of the next.
c/ 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 or repair.
■ The correct settings for use with this modem in New Zealand are as
follows:
ATB0 (CCITT operation)
AT&G2 (1800 Hz guard tone)
AT&P1 (Decadic dialing make-break ratio =33%/67%
ATS0=0 (not auto answer)
ATS10=less than 150 (loss of carrier to hangup delay, factory default of
15 recommended)
ATS11=90 (DTMF dialing on/off duration=90 ms)
ATX2 (Dial tone detect, but not (U.S.A.) call progress detect)
■ When used in the Auto Answer mode, the S0 register must be set with a
value of 3 or 4. This ensures:
(a) 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.
(b) caller identification information (which occurs between the first and
second ring cadences) is not destroyed.
