1. Where P is the port network number (1); C is the carrier designation (for example, A, B,
or C); and SS is the address of the slot in the carrier where the circuit pack is located
(for example, 01, 02, etc.).
The TN725 Speech Synthesis circuit pack provides four independent Speech
Synthesis Ports which can be connected to any of the voice time slots on the TDM
Bus. Each Speech Synthesis Port consists of a speech synthesizer device (SSD)
and is managed by a custom-coded programmable speech synthesizer (PSS)
controller. The PSS controller is, in turn, controlled by the on-board
microprocessor via a command interface specifically designed for this application.
The PSS controller's main function is the orderly transfer of encoded speech from
the speech vocabulary read-only memory (ROM) to the SSDs. The SSDs decode
it and produce 64 kb/s 5-255 PCM (Pulse Code Modulation) speech. The encoded
speech is stored in up to 512K bytes of on-board read-only memory (ROM). In
addition, each Speech Synthesis Port has an associated dual-tone multifrequency
(DTMF) receiver to receive touch-tone digits from a station set connected to the
port via a voice time slot. The station set may be connected to the Speech
Synthesis Port through either a line or trunk circuit.
When there is an incoming call to a port, the "listen" network time slot is
connected to the DTMF receiver input and the "talk" network time slot is
connected to the SSD output. This enables the Speech Synthesis Port to support
speech synthesis features or touch-tone input with voice response features. Some
of the features that use the Speech Synthesis Port's capabilities include Leave
Word Calling, Automatic Circuit Assurance, Automatic Wakeup (hotel-motel), and
do Not Disturb (hotel-motel).
The Speech Synthesis circuit pack should not be confused with the
Announcement circuit pack as different voice features are supported by each
circuit pack.
