BER - Bit Error Rate
CPE - Customer Premises Equipment
dB - Decibel
dBm - Decibels referenced to one milliwatt
dBmV - Decibels referenced to one millivolt
dBµV - Decibels referenced to one microvolt
DHCP - Dynamic Host Configuration Protocol
DOCSIS - Data Over Cable Service Interface Specification (DOCSIS is a trademark
or registered trademark of CableLabs in the United States and/or other
countries.)
EVM - Error Vector Magnitude
FEC - Forward Error Correction
Headroom (also called Overhead or Margin) - The number of decibels (dB)
by which a measurement exceeds the minimum defined requirements. The benefit
of headroom is that it reduces the bit-error rate (BER), and provides
a performance 'safety net' to help ensure that current and future high
speed applications will run at peak accuracy, efficiency and throughput
regardless of seasonal temperature changes on the HFC distribution system.
IP - Internet Protocol
MER - Modulation Error Ratio
MHz - Megahertz
Pre BER - Bit Error Rate before Forward Error Correction
Post BER - Bit Error Rate after Forward Error Correction
QAM - Quadrature Amplitude Modulation
QPSK - Quadrature Phase Shift Keying
SID - Service IDentifier
SNMP - Simple Network Management Protocol
SNR - Signal to Noise Ratio
TFTP - Trivial File Transfer Protocol
TOD - Time Of Day
TTL - Time-To-Live
