called channels.

Compression & Decompression.
Deactivation
The process of rendering a wireless phone
inactive.
DTMF (Dual-tone Multi-Frequency )
You send DTMF signals when you enter numbers

EVRC
(Enhanced Variable Rate Codec) EVRC is a new
global standard for compressing and
decompressing voice signals. EVRC uses a lower
bit rate (the number of bits sent per second) than
existing CDMA vocoders, while providing
significant improvements in voice quality. This
technology enables your phone to provide superb
voice quality while benefiting from the ability to
process more cellular voice calls using less
bandwidth than the voice codecs in CDMA
networks today.
Frequency
A measure based on time, as one or more waves
per second, in an electrical or light wave
information signal. A signal's frequency is stated
in cycles-per-second or Hertz (Hz).
