Traveler Information Voice System Subsystem
         Definition:
The 'Traveler Information Voice System' provides the caller interface and voice processing (voice recognition/synthesis) that supports voice-enabled traveler telephone information systems.   It provides wireline and wireless caller access to 511 systems and other telephone access mechanisms like 7 or 10 digit local access numbers.  It represents the boundary of the architecture where a call is received and processed and includes voice portal capabilities in scenarios where a distinct voice portal exists between ITS Centers and telecommunications providers.  The terminator gathers traveler information, alerts, and advisories from information service provider(s) and uses this information to support voice-based interactions with a traveler.
