The End of Data Marker is used to tell the carrier that the Card Destination 2 is complete so that the carrier can begin processing the call. If one is
needed, specify what tone to send in the End of Data Marker field. If the carrier uses a tone to indicate that it is ready for the phone
number, specify what tone is used in the Tone pull-down menu. From the Delay pull-down menu, select the time to wait for the end-of-data marker, or if No Tone was selected, how long to pause before sending.
