alternate mark inversion signal
A pseudoternary signal, representing binary digits. Successive marks are of alternately positive and negative
polarity and the absolute values of their amplitudes are normally equal. Spaces are of zero amplitude.
analog signal
A signal that has a continuous nature instead of pulsed or discrete.
analog-to-digital converter (ADC)
A device that converts an analog signal to a digital signal that represents equivalent information.
ANSI
American National Standards Institute
ASCII
American National Standard Code for Information Interchange
ASIC
Application Specific Integrated Circuit
ATM
Asynchronous Transfer Mode
ATPC
Automatic Transmitter Power Control is a feature of the radio that allows the output power to automatically
adapt to changing path conditions. This feature reduces interference with neighboring systems and permits
greater link density.
automatic gain control (AGC) voltage
A process that automatically adjusts gain as a function of a specified parameter, such as received signal level.
AUX
Auxiliary plug-in card
Auxiliary Data Channel
Channel that allows terminals in a link to communicate system information between themselves without using
customer tributaries.
AWG
A
merican Wire Gage. A wire diameter specification. The smaller the AWG number, the larger the
wire diameter.
Azimuth
T
he angle in the horizontal ground plane with respect to true North (such as, horizontal direction);
used in reference to antenna alignment.
B3ZS
Binary 3 zeros substitution. A “1” is substituted for every 3 zeros.
B8ZS
Binary 8 zeros substitution
