Misc. Init.
Param
This 20-character field defaults to blank ( ). This field supports
unspecified initialization parameters. The AT commands specified
in this free-form field to be sent to the external modem, always ini-
tialize last. This field is case in-sensitive.
Auto-Answer
Ring Count
This field controls the number of rings required before modems
automatically answer incoming calls. This 6-character field
defaults to (S0=10). Typically, the maximum permissible value is
255. 1-255 denote the number of incoming ring cycles. This field
is case in-sensitive.
Dial Type This field controls inter-register signaling used between modems
and Central Offices. This 3-character field defaults to (T) for tone
dialing. P indicates Pulse dialing, This field concatenates with the
dial string. This field is case in-sensitive.
Adjustable
Make/Break Ratio
This field can be of particular importance when using a modem
that may be transferable from country to country. This field con-
trols make/break ratios of pulses and DTMF dialing. Intel product
information supports make/break options for pulse dialing.
Intel uses “&P0” to select 39% make ratios 61% break ratios for
communication within the U.S. and Canada. “&P1” sets a 33%
make ratio and 67% break ratio for the U.K. and Hong Kong. This
5-character field defaults to blank ( ) and is case in-sensitive.
Dial Command
This 3-character field defaults to (D). It denotes the modem’s dial-
ing command. This field is case in-sensitive.
No Answer
Time-Out
Most off-the-shelf external modems provide timers that abandon
outbound data calls after predetermined intervals. Some modems
permit this timer to be disabled, allowing outbound calls to ring
indefinitely. AT&T Paradyne does not provide this capability,
because having outbound call attempts ring indefinitely is gener-
ally undesirable.
The internal modem must disable this parameter set it to at least
255 seconds. This parameter is not administrable. For external
modem connections, this parameter transmits first to the external
modem.
Type approval applications can override this hardcoded con-
stant, specifically in the U.K and other Western European nations,
with the “Misc. Init. Param:” field. (S7=255)
