WAN - Wide Area Network, the term normally used to describe the provider network “upstream” from
the residential gateway/router which delivers the broadband services. In the case where both a LAN
and WAN operate over MoCA on the same cable, the WAN uses a different channel.
Node - A MoCA-compliant device that is synchronized with and communicating on a MoCA network.
NC - Network Coordinator, the device (node) in the MoCA network that manages MoCA functionality
such as network admission, media access, and link maintenance. For more information, see
Example physical MoCA network on page 7-32.
STB - Set-Top Box, a device used to decode analog and digital TV signals for use by a television,
often simply called a “cable box.” The word “set” is short for “television set.”
Additional RF-related terms:
RF - Radio Frequency, referring to a frequency range of about 3 Hz to 300 GHz, commonly used for
the transmission of a variety of communications signals such as radio and TV. While better known for
over-the-air broadcast, frequencies in the RF range are also used to transport audio and video
services over physical media by cable TV and other providers.
Analog - In the context of audio and video transmission, refers to the practice of using composite
analog signals to deliver these services. Analog transmission has historically been the dominant
method (versus digital) due to overall reliability and efficiency, and simply because analog
transmission has historically been adequate to deliver the intended services. However, digital
transmission is gradually replacing analog transmission, due to the wide expansion of capabilities
that digital offers.
Digital - In the context of audio and video transmission, refers to techniques for modulating a digital
signal (that is, a bit stream) over analog carrier RF frequencies. In concept, digital transmission
allows a virtually limitless expansion of services, including a broad range of interactive features
between the subscriber and provider. However, the transition to digital is a gradual process because
it requires substantial changes to infrastructure and operational practice.
QAM - Quadrature Amplitude Modulation. See About QAM and the constellation graph on page 8-18.
Common acronyms:
FTTH/FTTP - Fiber To The Home/Fiber To The Premises
IP - Internet Protocol
IPTV - IP Television
