Glossary of Terms (continued)
MAC (Media Access Control): A unique identifier for the Ethernet hardware of
your DVC-1100.
NAT (Network Address Translation): A technology that allows multiple network
devices to share the same IP Address. NAT devices forward all incoming
and outgoing information to the correct network devices. Most NAT
devices have firewall capabilities.
QCIF (Quarter Common Intermediate Format): An intermediate video format.
QCIF resolution is 176x144. The DVC-1100 VideoPhone will send
QCIF-sized video only if the remote endpoint cannot decode CIF.
QoS (Quality of Service): Allows guaranteed bandwidth and packet delivery
between
Router: A device that attaches two or more network devices and forwards data
accordingly. Most consumer type routers act as DHCP servers, NATs
and simple firewalls.
DMZ (Demilitarized Zone): Devices set up to be in the router's DMZ will see
all network traffic.
Port Forwarding: The router will forward public-side incoming information to a
specified device on the private side. The router will forward only the
data that is received on the specified 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 specified path in which data travels. Each type of data that is
transmitted over the Internet travels down a specified port. A router will
forward information from one port to another, and a firewall will open
only a specified number of ports.
Site Survey: A function that looks for available wireless networks.
SQCIF (Subquarter Common Intermediate Format): An intermediate video
format. SQCIF resolution is 128x96. The DVC-1100 VideoPhone will
send SQCIF-sized video only if the remote endpoint cannot decode CIF
or QCIF.
