17 GLOSSARY

 

TERM

DEFINITION

 

MAC address, in a manner similar to a bridge. A switch is more

 

advanced because it can connect more than two segments.

synchronous

The SVG2500 uses synchronous timing for upstream data

 

transmissions. The CMTS broadcasts timing messages that

 

bandwidth is available. The SVG2500 reserves data bytes

 

requiring x number of mini-slots. The CMTS replies that it

 

can receive data at a specified time (synchronized). At the

 

specified time, the SVG2500 transmits the x-number of data

 

bytes.

symbol rate

Also known as baud rate. This is a measure of the number of

 

times per second a signal in a communications channel varies

 

or makes a transition between states (states being frequencies,

 

voltage levels or phase angles). Usually measured in symbols

 

per second (sps).

SYSLOG

A de-facto UNIX standard for logging system events.

DEFINITION

TBCP

Tagged Binary Communication Protocol

TCP

Transmission Control Protocol on OSI transport layer four

 

provides reliable transport over the network for data transmitted

 

using IP (network layer three). It is an end-to-end protocol

 

defining rules and procedures for data exchange between hosts

 

on top of connectionless IP. TCP uses a timer to track

 

outstanding packets, checks error in incoming packets, and

 

retransmits packets if requested.

TCP/IP

Transmission Control Protocol/Internet Protocol suite. It provides

 

standards and rules for data communication between networks

 

on the Internet. It is the worldwide Internetworking standard

 

and basic communications protocol of the Internet.

TFTP

Trivial File Transfer Protocol is a very simple protocol used to

 

transfer files.

TKIP

Temporal Key Integrity Protocol

Transparent

A method to enable all hosts on the wired Ethernet LAN, WLAN,

bridging

and USB connection to communicate as if they were all

 

connected to the same physical network.

transport layer

Layer of the OSI concerned with protocols for error recognition

 

and recovery. This layer also regulates information flow.

trunk

Electronic path over which data is transmitted.
