Asynchronous
Data Mode
This field will configure the modem as an asynchronous communications
device. This field is 8 characters long and is case in-sensitive. (&M0&Q0)
DTE Auto-Data
Speed
This option will adjust the speed of the data source (DTE) UART to the
outgoing (modem-to-modem) data rate. So, at maximum this speed would
be 9600 baud. This field is 6 characters long and is case in-sensitive.
Note that this field sets the link speed between the switch and the modem.
It does not set the speed of the modem. It is not desirable to have the
serial data fill the modem buffer faster than the outgoing data rate
especially because data compression is disabled. ( )
Disable Data
Compression
This field will turn off the default data compression algorithms that are in
use by most consumer modems. This field is 6 characters long and is
case in-sensitive. ( )
Enable Error
Control
This field will turn on the V.42 LAPM and MNP error control protocols, if
available on the modem. This field is 6 characters long and is case
in-sensitive.
This V.42/MNP/Buffer mode first attempts to negotiate V.42 error control
with the remote modem. If this fails, then the modem transitions to MNP,
and if this fails then no error control is used. ( )
Misc. Init.
Param
This field supports any initialization parameters that are not already
specified. The AT commands specified in this free-form field will be always
the last initialization parameters to be sent to the external modem. This
field is 20 characters long and is case in-sensitive. ( )
Auto-Answer Ring
Count
This field controls the number of rings required before the modem
automatically answers an incoming call, if and only if the switch doesn’t
answer first. (If the switch is healthy, it answers an incoming within the first
few rings.) This field is 6 characters long and is case insensitive. Typically,
the maximum permissible value for this register is 255. The values 1-255
denote the number of incoming ring cycles. (S0=10)
NOTE:
The number of rings is optimally set above 5, and if at all
possible, keep the default of S0=10.
Dial Type
This field controls the type of inter-register signaling to be used between
the modem and the Central Office. Use “T” for tone dialing and “P” for
pulse dialing. The field length is be 3 characters long and is case
in-sensitive. This field will be concatenated with the dial string. (T)
Adjustable
Make/Break Ratio
This field can be of particular importance when using a modem that may
be transferable from country to country. The intent of this field is to control
the make/break ratios of pulses and DTMF dialing. The Intel product
information has support for the different make/break options for pulse
dialing only.
Intel uses the option “&P0” to select a ratio of 39% make and 61% break
for communication within the U.S. and Canada. The option “&P1” sets a
ration of 33% make and 67% break for the U.K. and Hong Kong.
This field is 5 characters long and is case in-sensitive. ( )
Dial Command
This field simply denotes the dialing command of the modem. This is a
fairly standard command. (D)
