5. Manual operation
5.1 Introduction
Sometimes the modem may have to be used in a special
configuration. It may be suitable for the user to operate this modem
with switches at the front rather than using commands. Further, it
may not be possible to give commands to the modem from the
terminal equipment. (ex. a synchronous terminal). The switches and
display make it possible to control as well as setup the modem from
front panel.
5.2 Switches and indicators on the front fascia
5.2.1 Switches at front panel
The CURS and ROLL/EXEC switches make it possible to
control and configure the modem using the display menu at the
frontpanel.
The switches may be divided in two groups:
VOICE/DATA, MAN/AUTO and the LEA/SW switches which are
"hot keys" for some often used functions.
VOICE/DATA (toggle):
Used to toggle between data mode and off line command mode
i.e. tf the modem is disconnected, pressing this switch will
connect modem to line and start a handshake.
If the modem is connected this switch may be used to
disconnect modem from line.
MAN/AUTO (Alternating):
In AUTO position the auto answer is enabled even if S-reg.0=0.
In MANUAL position automatic answer must be set in SETUP
menu or by commands from DTE. Otherwise the auto answer
function is disabled.
