A measure of battery capacity. For example, a 1.0Ah battery can
nominally supply one Ampere of current for one hour.
A high-quality type of cable, used for gigabit Ethernet (1000BaseT) connec-
tions. When purchasing Ethernet cables, always look for Category 5e cable.
A thin wire, used to connect your television and Telephony Gateway to the
cable TV system. You can buy coax from any electronics retailer and many
discount stores.
Customer Premise Equipment. This is the equipment that is plugged in to
the Telephony Gateway; typically a computer or hub.
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).
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 de-
vice connecting to the network. DHCP allows the cable company to
configure your computer's networking software for you.

name (such as www.example.com) with an IP address.
