This can be accomplished via the host firmware or external hardware as shown in Figures 2 and 3 respectively.

In Figure 2, the microcontroller output port going to the MUTE pin is used as a shunt for low impedance dialing and is asserted for 80mS when the OH signal is asserted. This method is preferred when the user has control of the host firmware and can easily write a subroutine to accomplish this function. For users that do not have easy access to the modem firmware, some external hardware can be added to accomplish the same function. Figure 3 shows a monostable (one-shot) such as a 555 timer which is designed to generate an 80mS low going pulse upon the assertion of the OH signal. This 80mS pulse is ANDed with the low impedance pulse dial shunt signal which overrides the 80mS signal when pulse dialing is enabled. The pulse dial shunt signal is included as a standard output pin in most modem chipsets. This pin is activated when an ATDP command is issued to the modem.
