Configuration Files; Downstream And Upstream Transmissions; Cable Frequencies - Hitron CDA-RES User Manual

MAC addresses are the most reliable way of identifying network devices, since IP
addresses tend to change over time (whether manually altered, or updated via
DHCP).
Each MAC address displays as six groups of two hexadecimal digits separated by
colons (or, occasionally, dashes) for example 00:AA:FF:1A:B5:74.
NOTE: Each group of two hexadecimal digits is known as an "octet", since it
represents eight bits.
Bear in mind that a MAC address does not precisely represent a computer on your
network (or elsewhere), it represents a network device, which may be part of a
computer (or other device). In the case of the CDA-RES, each internal module (cable
modem module, Ethernet module, etc.) possesses its own MAC address.

Configuration Files

The CDA-RES's configuration (or config) file is a document that the CDA-RES
obtains automatically over the Internet from the service provider's server, which
specifies the settings that the CDA-RES should use. It contains a variety of settings
that are not present in the user-configurable Graphical User Interface (GUI) and can
be specified only by the service provider.
2.7

Downstream and Upstream Transmissions

The terms "downstream" and "upstream" refer to data traffic flows, and indicate the
direction in which the traffic is traveling. "Downstream" refers to traffic from the
service provider to the CDA-RES, and "upstream" refers to traffic from the CDA-RES
to the service provider.
2.8

Cable Frequencies

Just like radio transmissions, data transmissions over the cable network must exist
on different frequencies in order to avoid interference between signals.
The data traffic band is separate from the TV band, and each data channel is
separate from other data channels.
