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 dialling 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 dealing 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 dialling is to use DTMF tones (ATDT...) as this
is faster and more reliable than pulse (decadic) dialling. If for some
reason you must use decadic dealing, 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 Dialling"
standard.
Number to be dialled: 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 dealing 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.
