MODEM 32144
A 4-wire line must be used
(conditioned or unconditioned),
and both connected modems must
be set for V.33 operation.
After the V.33 Leased Line
Quick Setup has been selected,
the modem immediately begins
the training sequence, meaning it
is ready to communicate with the
other modem. The second modem
to come online will automatically
establish the data link (regardless
of whether it is the local or remote
unit).
When the local modem has
successfully established a
connection with the remote unit,
the EIA status screen should be
present. Typically the screen will
look like this:
2.7 2-Wire Dial Bell 208 Operation
(Quick Setup 11–12)
The modem supports Bell 208
operation. To confirm this, select
SETUP from MAIN MENU screen
2. Then select QUICK from SETUP
screen 1. Press the right arrow
pushbutton repeatedly to cycle
through the Quick Setup screens. If
you can access the two Quick Setup
screens shown below, the unit
supports Bell 208 operation.
