Patent ID: 7596106

Claim:
A system for generating a flexible time slot in an internal voice mail system, comprising: a first counter/time slot playback device operating as a counter in response to a system synchronization signal and outputting at least one time slot (TS) signal; a second counter/time slot playback device operating as a counter in response to the system synchronization signal and outputting at least one time slot (TS_n) signal; a transmit start of transfer (TSX) channel synchronization generator generating a proper TSX channel synchronization signal in response to channel information data transmitted from the internal voice mail system; and a flexible TSX generator, after synthesizing the signals input from the first counter/time slot playback device and the second counter/time slot playback device and generating at least one synthesized TSX signal, outputting a TSX signal corresponding to a TSX channel synchronization signal generated by the TSX channel synchronization generator.
