DEFINITION
Link Control Protocol establishes, configures, and tests data link
connections used by PPP.
The time required for a signal to pass through a device. It is often
expressed in a quantity of symbols.
light-emitting diode
An L2TP network server is a termination point for L2TP tunnels where
PPP frames are processed and passed to higher layer protocols. LNS
can operate on any platform that terminates PPP. The LNS handles the
server side of the L2TP protocol. L2TP relies only on the single media
over which L2TP tunnels arrive. The LNS can have a single LAN or
WAN interface, but can terminate calls arriving at any of the LAC's full
range of PPP interfaces (asynchronous, synchronous, ISDN, V.120,
etc.). The LNS initiates outgoing calls and receives incoming calls. LNS
is analogous to a home gateway in L2F technology.
A test that loops the transmit signal to the receive signal. Usually, the
loopback test is initiated on a network device. The test is used to verify
a path or to measure the quality of a signal on that path.
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.
One megabyte; equals 1,024 x 1,024 bytes, 1,024 kilobytes, or about 8
million bits.
Million bits per second (megabits per second). A rate of data transfer.
The various physical environments through which signals pass; for
example, coaxial, unshielded twisted-pair (UTP), or fiber-optic cable.
A management information base is a unique hierarchical structure of
software objects used by the SNMP manager and agent to configure,
monitor, or test a device.
Megahertz — one million cycles per second. A measure of radio
frequency.
