Abstract

When using a subscriber unit, it is possible to record the keystrokes for later use to redial. However, current subscriber unit merely record the sequence of key strokes without preserving any information regarding the interval between key strokes, or intervals before an additional dual tones multifrequency (DTMF) signals entered after a phone number was dialed. Currently if one tries the latter, an error message will be sent back to the subscriber use.

PROGRAMMABLE INTERMllTENT DTMF

INTRODUCTION

  When using a subscriber unit, it is possible to record the keystrokes for later use to redial. However, current subscriber unit merely record the sequence of key strokes without preserving any information regarding the interval between key strokes, or intervals before an additional dual tones multifrequency (DTMF) signals entered after a phone number was dialed. Currently if one tries the latter, an error message will be sent back to the subscriber use.

  If one wants to successfully access a system with menu and submenus one has to wait and enter DTMF codes as the system allows one to proceed. This is problematic when driving a vehicle or when being occupied and using the subscriber unit. Preservation of rime inrervals between key strokes would be useful when using an automatic dial mode to access systems that are only capable of recogniz- ing intermittent (DTMF) signals, e.g., voice mail system, pagers with pin number.

DESCRIPTION

The present invention proposes to allow a sub- scriber unit to enter a mode in which key strokes

which generate DTMF tones and the time intervals between keystrokes are recorded for later use. Before making a call, a user would enter the special mode through any of a number of possible methods,
i.e., menus soft-keys, etc. Once in the special mode, the subscriber unit would record the key strokes and the time interval between key strokes until the user exited the special mode. The user would then be able to save the recorded information as a particular entry, by recalling an entry later on, not only would the keystrokes be repeated but the intervals between the keystrokes would also be repeated, thereby accommodating the needs of the system called.
