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.
