DEFINITION
A device that enables communication between networks using
different protocols. The SBG901 enables up to 245 computers
supporting IEEE 802.11b/g or Ethernet to share a single broadband
Internet connection.
Internet Service Provider
The Media Access Control address is a unique, 48-bit value
permanently saved in ROM at the factory to identify each Ethernet
network device. It is expressed as a sequence of 12 hexadecimal
digits printed on a label on the bottom of the SBG901. You need to
provide the HFC MAC address to the Internet Service provider. Also
called an Ethernet address, physical address, hardware address, or
NIC address.
Network Address Translation is an Internet standard for a LAN to use
one set of IP addresses for internal traffic and a second set of IP
addresses for external traffic.
A pass-through client on the SBG901 LAN obtains its public IP
address from the Internet Service provider's DHCP server.
A feature that enables one port (source) on the SBG901 to be copied
to another port (destination) to be studied. The destination mirrors
the transmitted (from) or received (to) data on the source port to
enable the person managing the network to monitor activity.
A mechanism that allows incoming communication with specified
applications. Primarily used for gaming applications.
An IP address assigned to a computer on the SBG901 LAN by the
DHCP server on the SBG901 for an address-specified lease time.
Private IP addresses are used by the SBG901 LAN only; they are
invisible to devices on the Internet. See also public IP address.
The IP address assigned to the SBG901 by the Internet Service
provider. A public IP address is visible to devices on the Internet. See
also private IP address.
Quality of service describes the priority, delay, throughput, and
bandwidth of a connection.
The most common type of connector for household or office phones.
