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
