Method and system for modem pulse dialing in a telecommunication system

A method for modem pulse dialing in a telecommunication system, comprising the steps of:

• determining if modem pulse dialing is requested in a telecommunication system having a modem and an associated modem driver;
• and
• responsive to the modem pulse dialing request, activating a fast timer in the modem driver in association with a slow timer in the modem;
• stopping the fast timer by disabling a timer interrupt when the pulse dialing is required;
• calculating a divisor value to set-up an interrupt period for the pulse dialing;
• starting the fast timer by enabling the interrupt utilizing the interrupt period;
• synchronizing the fast timer and the slow timer to count in millisecond increments whereby the modem continuously operates utilizing both the slow timer and the fast timer for producing a timer resolution necessary for completing the modem pulse dialing;
• and
• releasing control to an operating system during inter-digit delay time.
