208 Glossary
CWID (Continuous Wave IDentification) is a method of
automatically identifying the base station using a Morse code.
Continuous wave means transmission of a signal with a single
frequency that is either on or off, as opposed to a modulated
carrier.
Digital-to-Analog Converter. A device for converting a digital
signal to an analog signal that represents the same information.
DCS (digital coded squelch), also known as DPL (digital private
line), is a type of subaudible signalling used for segregating groups
of users. DCS codes are identified by a three-digit octal number,
which forms part of the continuously repeating codeword.
When assigning DCS signalling for a channel, you specify the
three-digit code.
De-emphasis is a process in the receiver that restores pre-
emphasised audio to its original relative proportions.
Duty cycle is used in relation to the PA. It is the proportion of
time (expressed as a percentage) during which the PA is operated.
The TB8100 PA can be operated continuously.
Electronic Industries Alliance. Accredited by the American
National Standards Institute (ANSI) and responsible for
developing telecommunications and electronics standards in the
USA.
Electromagnetic Compatibility. The ability of equipment to
operate in its electromagnetic environment without creating
interference with other devices.
European Telecommunications Standards Institute. The non-
profit organisation responsible for producing European
telecommunications standards.
