Asynchronous
Data Mode This field will configure the mod em as an asynchronous
communications devi ce. This field is 8 characters l ong 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-mo dem) data rate. So, at maximum this
speed would b e 9600 baud. This field is 6 char acters long and is
case in-sensitive.
Note that this field sets the link speed b etween the switch and the
modem. It does not set the spee d of the modem. It is not
desirable to have the serial d ata fill the modem buffer faster than
the outgoing data rate esp ecially because d ata 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-sen sitive. ( )
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 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 control is used . ( )
Misc. Init.
Param This field supports any initialization p arameters that are not
already specified . The AT commands specified in this free-form
field will be always the last initialization p arameters to be sent to
the external modem. This field is 20 c haracters long and is c ase
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 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 permissible v alue
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 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 d ial string. (T)
