Glossary
The following is a list of common cable and networking terms.
Amp-hour (Ah)
A measure of battery capacity. For example, a 1.0Ah battery can nominally
supply one Ampere of current for one hour.
Category 5 (Cat5)
A high-quality type of cable, used for Fast Ethernet (100BaseT) connec-
tions. When purchasing Ethernet cables, always look for Category 5 cable.
Coaxial cable (coax)
A thin round cable used to connect your television and Telephony Modem 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 telephony modem; typically a computer, hub, or router.
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).
DECT
Digital Enhanced Cordless Telecommunications. A standard for portable
telephones. DECT operates on a different frequency band from 2.4GHz
cordless phones, so it does not interfere with other cordless phones or with
wireless LANs (WiFi).
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 cable company to con-
figure your computer’s networking software for you.
