Toshiba 5000 Series User Manual page 14

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)
ATS6=2, 3, 4, 5, 6 or 7 (Blind dial delay, factory default value of 2 is recom-
mended)
ATS7=less than 90 (Time to wait to carrier after dialing)
ATS10=less than 150 (loss of carrier to hangup delay, factory default of 14
recommended)
ATS11=95 (DTMF dialing on/off duration=95 ms)
ATX2 (Dial tone detect, but not (U.S.A.) call progress detect)
When used in the Auto Answer mode, the SO register must be set with a value
between 2 and 10. 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.
