Loss Of Frame is an error indicating that the receiving equipment has lost a frame. Loss Of Signal is an error indicating that the receiving equipment has lost the signal.
Media Access Control is a physical address associated with a device such as a NIC. For modem configuration, the MAC is used to map inbound traffic (from a remote IP address) to an internal (LAN) IP address. Used with 1483 Bridging/Routing Mode.

Cyclic Redundancy Check is a method used to verify the accuracy of data

 

transmission.

 

 

 

 

 

DMT

Discrete Multi-Tone is a modulation coding for an ADSL line. DMT is the modulation

 

technology used for the Megabit Modem 500L ADSL.

 

 

downstream

Communications from a service provider to a user.

 

 

traffic

 

 

 

 

 

 

encapsulation

The inclusion of data in a protocol header prior to transmission, which enables

 

successful data transmission between different protocol networks.

gateway

A device (generally a router) that provides translation services to allow

 

communication between two dissimilar networks.

 

 

IP

Internet Protocol is a TCP/IP protocol that controls packet transmission.

IP address

 

M

 

 

 

A 32-bit address used in IP routing. The address consists of four octets separated by
