DTE Auto-Data
Speed This option will adjust the speed of the data source (DTE) UART to
the outgoing (modem-to-mo dem) data rate. So, at maximum this
speed would b e 9600 baud. This field is 6 c haracters 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 c ompression algorithms that
are in use by most consumer mod ems. This field is 6 characters
long and is case in-sensitive. (&K0)
Enable Error
Control This field will turn on the V.42 LAPM and MNP error control
protocols, if availabl e on the modem. This field is 6 charac ters 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 con trol is used. ( )
Misc. Init.
Param This field supports any initialization p arameters that are not already
specified. The AT command s specified in this free-form field will be
always the last initialization parameters to b e sent to the external
modem. This field is 20 charac ters long and is case in-sensitiv e. ( )
Auto-Answer Ring
Count This field controls the number of ring s required before the modem
automatically answers an incoming call, if and only if the switc h
doesn’t answer first. (If the switch is healthy , it answers an
incoming within the first few ring s.) This field is 6 characters long
and is case insensitive. Typic ally, the maximum permissib le value
for this register is 255. The values 1-255 denote the num ber of
incoming ring c ycles. (S0=10)
NOTE:
The number of rings is optimally set ab ove 5, and if at all
possible, keep the d efault of S0=10.
Dial Type This field controls the type of inter -register signaling to b e used
between the modem and the Central Offic e. Use “T” for tone dialing
and “P” for pulse d ialing. The field length is b e 3 characters long
and is case in-sensitive. This field will be concatenated with the di al
string. (T)
