Dialing Characters; Dial Pause [,]; Long Pause [I] - Xerox Document Centre 240 Reference Manual

Dialing Characters

Dialing characters are special characters that provide a unique
capability when dialing through a telephone network or to a specific
fax machine. Depending on the setup of the telephone and
communication lines, some or all of the following characters may be
needed.
Dial Pause [,] is also available as a button on the keypad.

Dial Pause [,]

This character provides a 3 second pause in dialing. This pause gives
the Document Centre time to switch from an inside line to an outside
line during automatic dialing.
For additional pause time, add multiple pause characters. However,
do not add pauses unless a delay is expected. If using charge code
numbers, enter a pause after the fax number, but before the charge
code numbers, to ensure that the telephone line is ready to accept the
numbers.

Long Pause [I]

This character provides a 5 second pause in dialing. This pause is
used if you normally have a long wait for a dial tone.
