AMBE+2™ Advanced Multiband Excitation. A voice compression technology patented
by Digital Voice Systems, Inc and used in the vocoders of P25 radios.
ANI Automatic Number Identification. A service that provides the receiver of a
call with a numerical identifier or alphanumeric label of the caller.
APCO The Association of Public Safety Communications Officials in the United

power is below the configured power shutdown voltage. In battery
protection mode, the PMU will shut down to protect the battery if it loses
AC power.
bearer network Telecom equipment that is used to carry user data.
BER Bit Error Rate. A measure of the quality of digital transmission, expressed
as a percentage. The BER indicates the proportion of errors to correctly
received digits in a received signal.
C4FM Compatible Four-level Frequency Modulation. A modulation scheme
