QoS (Quality of Service): Allows guaranteed bandwidth and packet delivery
between network devices over a network.
Router: A device that attaches two or more network devices and forwards data
accordingly. Most consumer type routers act as DHCP servers, NATs
and rewalls.
DMZ (Demilitarized Zone): Devices set up to be in the router’s DMZ will see
all network trafc.
Port Forwarding: The router will forward public-side incoming information to a
specied device on the private side. The router will forward only the data
that is received on the specied ports. This is usually set through the
advanced settings in the router’s web interface. Also known as Virtual
Server or Firewall Rules.
Ports: A port is a specied path in which data travels. Each type of data that is
transmitted over the Internet travels down a specied port. A router will
forward information from one port to another, and a rewall will open
only a specied number of ports.
SQCIF (Subquarter Common Intermediate Format): An intermediate video
format. SQCIF resolution is 128x96. The DVC-1000 VideoPhone will
send SQCIF-sized video only if the remote endpoint cannot decode
CIF or QCIF.
SLIC (Subscriber-Line Interface Circuit): Provides a phone’s analog dial
tone, busy tone, dual-tone multiple-frequency (DTMF) generation and
decoding, caller ID and ring-signaling functions. The SLIC allows the
DVC-1000 to work with a standard telephone without connecting to the
phone system.
TCP (Transmission Control Protocol): An Internet protocol used by the
DVC-1000 VideoPhone in addition to UDP.
UDP (User Datagram Protocol): The Internet protocol most commonly used by
the DVC-1000 VideoPhone to send and receive audio and video data.
WAN (Wide Area Network): A network that is designed to span large distances.
See LAN.
