Glossary
A
Amp-Hour
A measure of battery capacity. For
example, a 1.0Ah battery can nominally
supply one Ampere of current for one
hour.
C
Category 5e (Cat5e)
A high-quality type of cable, used for
gigabit Ethernet (1000BaseT) connections.
When purchasing Ethernet cables, always
look for Category 5e cable or higher.
Coaxial cable (coax)
A thin wire, used to connect your
television and SBV3202 to the cable TV
system. You can buy coax from any
electronics retailer and many discount
stores.
CPE
Customer Premise Equipment. This is the
equipment that is plugged in to the
SBV3202; typically, a computer or hub.
Cross-over
An Ethernet cable used to connect two
hubs (or a hub and a cable modem)
together. Also, some Ethernet hubs may
have built-in cross-over on one or more
ports (which eliminates the need for a
cross-over cable).
D
DHCP
Dynamic Host Configuration Protocol. An
IP protocol used to provide an IP address
and location of services (such as DNS and
TFTP) needed by a device connecting to
the network. DHCP allows the service
provider to configure your computer’s
networking software for you.
DNS
Domain Name Service (Server). An IP
service that associates a domain name
(such as www.example.com) with an IP
address.
DOCSIS
Data Over Cable System Interface
Specification. The interoperability
standards used for data communications
equipment on an HFC network.
Downstream
In an HFC network, the direction from
the head-end to the subscriber. Some
older cable documentation may refer to
this as the forward path.
E

Embedded Multimedia Terminal
Adapter. An MTA device that is
integrated with a cable modem.
