Termination Status. Indicates whether a mobile station must terminate the call when it is on an analog
voice channel.
Supervisory Audio Tone (SAT). One of three tones in the 6 kHz region that is transmitted on the
forward analog voice channel by a base station and transponder on the reverse analog voice channel
by as mobile station.
Supplementary Digital Color Code (SDCC1, SDCC2). Additional bits assigned to increase the
number of color codes from four to sixty four, transmitted on the forward analog control channel.
Symbol. See Code Symbol and Modulation Symbol.
Sync Channel. Code channel 32 in the Forward CDMA Channel which transports the synchronization
message to the mobile station.
Sync Channel Superframe . An 80ms interval consisting of three Sync Channel frames (each
26.666…ms in length).
System. A system is a cellular telephone service that covers a geographic area such as a city.
Metropolitan region, country, or group of countries. See also Network.
System Time. The time reference used by the system. System Time is synchronous to UTC
time(except for leap seconds) and used the same time origin as GPS time. Offset by the propagation
delay from the base station to the mobile station. See also Universal coordinated Time.
Timer-Based Registration. A registration method in which the mobile station registers whenever a
counter reaches a predetermined value. The counter is incremented an average of once per 80 ms
period.
Time Reference. A reference established by the mobile station that is synchronous with the earliest
arriving multipath component used for demodulation.
TOLR . See Transmit Objective Loudness Rating.
Traffic Channel. A communication path between a mobile station and base station used for user
and signaling traffic. The term Traffic Channel implies a Forward Traffic Channel and Reverse Traffic
Channel pair. See also Forward Traffic Channel and Reverse Traffic Channel.
Traffic Channel Preamble. A sequence of all-zero frames that is sent at the 9600 bps rate by the
mobile station on the Reverse Traffic Channel. The Traffic Channel preamble is sent during
initialization of the Traffic Channel.
Transmit Objective Loudness Rating(TOLR). A perceptually weighted transducer gain of
telephone transmitters relation sound pressure at the microphone to voltage at a reference electrical
termination. It is normally specified in dB relative to one millivolt per Pascal. See IEEE Standard
269-1992, IEEE Standard 661-1979, CCITT Recommendation P.76 , and CCITT Recommendation.
P.79
Unique Challenge-Response Procedure. An exchange of information between a mobile station
and a base station for the purpose of confirming the mobile station’s identity. The procedure is initiated
