Using Pulse Dialing
In some locations, analog telephone users must dial telephone calls using
pulse dialing instead of tone dialing (also called Dual Tone Multi
Frequency, or DTMF , dialing).
Your administrator must configure the Analog Line Card ports for pulse
dialing.
Examples:
■
Some of your telephone lines are provided by a telephone company
that supports only pulse dialing while other lines are provided by a
different telephone company that supports DTMF dialing.
■
Your organization’s telephone service provider offers low-cost,
pulse-dialing-only service.
