SCAN STROBE SIGNAL
A control signal by which the CPU reads the dial data on the dial data bus at an optimum timing when the
CPU scans the data.
SERIAL DATA
The data in which bits are transmitted one after another when the data is processed or transferred. The
bits constituting the data are arranged in serial at instants. So they can be transmitted on a signal line.
SERIAL TO PARALLEL CONVERSION
In general, a CPU processes parallel data, while a transmitting device or a simple terminal equipment
processes serial data. When the data from the transmitting device or terminal equipment is transfered to
the CPU, the serial data is necessary to be converted into the parallel data. This is called Serial-To-Parallel
Conversion.
SG (Signal Generating and Distributing Unit)
Composed of 8 kinds of signal generators (calling, privacy/disconnected, busy, dialing, zone paging, all call,
priority/executive priority, registration confirmation/call holding/mic-off) and distributors. This unit
distributes under HC control the required service signal tones to the individual links.
SIDE TONE
The sound of the talker's own voice heard from his station handset.
SPACE-DIVISION SWITCHING SYSTEM
A type of switching system in which a speech signal is transmitted by spatial branched out connection
line.
SPEECH PATH
In the multiplexed carrier system or radio system, a line on which voice signal transmitting is possible.
Tl (Tie-line Interface Unit)
When tie-line system is built for connecting 2 or 3 exchanges, this unit transmits and receives the audio
signals and dial data among the exchanges.
