Configuration Issues For Modems

Modems may be used to allow data to be transferred over telephone lines. Data can
be transferred either:
between two Network 3000-series controllers
"
between a Network Master (PC) and a Network 3000-series controller
"
A pair of modems is required for each setup; i.e. there must be one modem on each
end of the telephone line. Depending upon the Network 3000 series controller(s)
you are using, they may have an internal modem already installed. In other cases,
external modems must be purchased.
The telephone line can be either a private line or public switched network
line. A private line means there is a single dedicated phone connection between the
two modems, eliminating any need for dialing. A public switched network line
means that the modem must dial a number using the public telephone system.
Which Modems Are Supported?
Bristol Babcock currently offers three different modems for use with our Network
3000 product lines. These are shown in the table, below:
Modem: Baud Rate:
BBI 1200 bps 1200
Modem
BBI 1200 bps - 1200
PL Modem
BBI 9600 bps - 9600
PSTN Modem
Note: Older Bristol modems such as the SNM are no longer sold by Bristol, and so will not be
discussed.
Because of the large number of modems available on the market, it is NOT possible
for Bristol Babcock to test and support non-Bristol Babcock modems. Bristol
Babcock's Application Support Group, however, has successfully tested current
Bristol equipment with U.S. Robotics modems.
The table, on the next page, shows how modem characteristics should be set when
connecting a U.S. Robotics modem to an Open BSI workstation.
