Cable Modem
Termination
System - Network
Side Interface
(CMTS-NSI) The interface, defined in [DOCSIS3], between a CMTS and the equipment on
its network side.
Cable Modem to
CPE Interface
(CMCI) The interface, defined in [DOCSIS4], between a CM and CPE.
Carrier Hum
Modulation The peak-to-peak magnitude of the amplitude distortion relative to the RF
carrier signal level due to the fundamental and low-order harmonics of the
power-supply frequency.
Carrier-to-Noise
Ratio (C/N or CNR) The voltage difference between the digitally-modulated RF carrier and the
continuous random noise. CNR is measured in decibels (dB).
CM See Cable Modem.
CMCI See Cable Modem to CPE Interface.
CMTS See Cable Modem Termination System.
C/N or CNR See Carrier-to-Noise Ratio.
CNAME A record that contains an alias or nickname for the official domain name
(also known as the canonical name).
Cross-Modulation A form of television signal distortion where modulation from one or more
television channels is imposed on another channel or channels.
Customer Premises
Equipment (CPE) Equipment at the end user’s premises. This equipment may be provided by
the end user or the service provider.
Data Link Layer Layer 2 in the Open System Interconnection (OSI) architecture; the layer that
