IP—Internet Protocol.
IP-STE—Internet Protocol secure terminal equipment.
ISDN—Integrated Services Digital Network. Communication protocol offered by telephone companies
that permits telephone networks to carry data, voice, and other source traffic.
that permits telephone networks to carry data, voice, and other source traffic.
MAC address—Standardized data link layer address that is required for every port or device that
connects to a LAN. Other devices in the network use these addresses to locate specific ports in the
network and to create and update routing tables and data structures. MAC addresses are 6 bytes long and
are controlled by the IEEE. Also known as a hardware address, MAC layer address, and physical address.

MGCP—Media Gateway Control Protocol. A merging of the IPDC and SGCP protocols.
MLPP—Multilevel Precedence and Preemption.
MoIP—Modem over IP.
NM—network module.
NSE—named signaling events.
RTP—Real-Time Transport Protocol. Commonly used with IP networks. RTP is designed to provide
end-to-end network transport functions for applications transmitting real-time data such as audio, video,
or simulation data over multicast or unicast network services. RTP provides such services as payload
type identification, sequence numbering, time-stamping, and delivery monitoring to real-time
applications.

SCCP—Skinny Client Control Protocol.
SPRT—Simple Packet Relay Transport.
SRST—Survivable Remote Site Telephony.
SSE—state signaling events.
STCAPP—SCCP Telephony Control Application.
STE—Secure Terminal Equipment.
STU—Secure Telephone Unit.
TFTP— Trivial File Transfer Protocol. Simplified version of FTP that allows files to be transferred from
one computer to another over a network, usually without the use of client authentication (for example,
username and password).

username and password).
UDP—User Datagram Protocol
V.150.1—Modem relay specification.
VBD—voice band data (modem pass-through).
VIC—Voice interface card.
VoIP— Voice over IP. The capability to carry normal telephony-style voice over an IP-based internet
with POTS-like functionality, reliability, and voice quality. VoIP enables a router to carry voice traffic
(for example, telephone calls and faxes) over an IP network. In VoIP, the DSP segments the voice signal
into frames, which then are coupled in groups of two and stored in voice packets. These voice packets
are transported using IP in compliance with ITU-T specification H.323.

XML— eXtensible Markup Language. A standard maintained by the World Wide Web Consortium
(W3C). It defines a syntax that lets you create markup languages to specify information structures.
Information structures define the type of information, for example, subscriber name or address, not how
the information looks (bold, italic, and so on). External processes can manipulate these information
structures and publish them in a variety of formats. Text markup language designed to enable the use of
SGML on the World Wide Web. XML allows you to define your own customized markup language.
