ISP	Internet Service Provider.
IMUX	Inverse Multiplexer. Equipment that
	combines 64Kbps channels and presents
	them to the user's terminal equipment as if
	they were a single larger bandwidth channel.
IP	Internet Protocol. An IP address is a number
	that identifies a computer connected to the
	Internet. Every computer that is connected to
	the Internet must have unique IP address.
	Currently, an IP address consists of four
	sections separated by periods. Each section
	contains an 8-bit value represented as a
	number ranging from 0 to 255. The allocation
	of these IP addresses follows a two-level
	architecture that assigns IP numbers to a
	network and the hosts on that network.
IP Precedence	IP precedence tells downstream networking
	equipment (mainly routers) to give priority to
	audio and video data. It marks each audio
	and video packet with a user-defined
	precedence (the default is 4). Only audio,
	video, and far-end camera control-packets
	are marked. Control packets (such as
	opening and closing of connections,
	channels, etc.) are not marked with
	precedence.
	The user may specify any one of 8 levels
	(0-7) of precedence with 0 signifying no
	priority and 7 signifying the highest priority.
	It is recommended by networking equipment
	vendors to use 4 for multimedia data. By
	default, IP precedence is disabled by most
	routers and is not enabled on the Internet.
ISDN	Integrated Services Digital Network. Fully
	digital telephony service, available at 128
	Kbps (BRI), 1.544 Mbps (PRI), and
