DEFINITION

 

 

 

 

 

gateway

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.

 

 

 

 

ISP

Internet Service Provider

 

 

 

 

MAC address

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.

 

 

 

 

NAT

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.

 

 

 

 

pass-through

A pass-through client on the SBG901 LAN obtains its public IP

 

 

address from the Internet Service provider’s DHCP server.

 

 

 

 

port mirroring

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.

 

 

 

 

port triggering

A mechanism that allows incoming communication with specified

 

 

applications. Primarily used for gaming applications.

 

 

 

 

private IP

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.

 

 

 

 

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.

 

 

 

 

QoS

Quality of service describes the priority, delay, throughput, and

 

 

bandwidth of a connection.

 

 

 

 

RJ-11

The most common type of connector for household or office phones.

 

 

 

 

RJ-45

An 8-pin modular connector; this is the most common connector

 

 

type for 10Base-T or 100Base-T Ethernet networks.
