User’s Manual x
(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 sec-
onds 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.
■ The preferred method of dialing is to use DTMF tones (ATDT...) as this
is faster and more reliable than pulse (decadic) dialing. If for some
reason you must use decadic dialing, your communications program
must be set up to record numbers using the following translation table
as this modem does not implement the New Zealand “Reverse Dialing”
standard.
Number to be dialed: 0 1 2 3 4 5 6 7 8 9
Number to program into computer: 0 9 8 7 6 5 4 3 2 1
Note that where DTMF dialing is used, the numbers should be entered
normally.
■ The transmit level from this device is set at a fixed level and because of
this there may be circumstances where the performance is less than
optimal. Before reporting such occurrences as faults, please check the
line with a standard Telepermitted telephone, and only report a fault if
the phone performance is impaired.
