CSU/DSU (Channel Service Unit/Data Service Unit) A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device about the size of an external modem that converts a digital data frame from the communications technology used on a local area network (LAN) into a frame appropriate to a wide-area network (WAN) and vice versa.he Data Service Unit (DSU) manages line control, and converts input and output between RS-232C, RS-449, or V.xx frames from the LAN and the time-division multiplexed (TDM) DSX frames on the T-1 line. The DSU manages timing errors and signal regeneration.

Cisco IOS Voice Troubleshooting and Monitoring -- Fax Relay The fax interface-type modem global configuration command forces fax calls to a modem (usually for T.37 Store and Forward fax) and not to a DSP. For Cisco fax relay to work, the fax call must be sent to a DSP, which means it must be configured by the issuing of the fax interface-type vfc command.

- Regenerator-Device that restores a degraded digital signal for continued transmission; also called arepeater. SDH (Synchronous Digital Hierarchy) - The ITU-T-defined world standard of transmissionwhose base transmission level is 52 Mbps (STM-0) and is equivalent to SONET's STS-1 or OC-1transmission rate.ynchronous Digital Hierarchy is a world standard, and as such, SONETcan be considered a subset of SDH.Transmission standards in the United States, Canada, Korea, Taiwan, and Hong Kong (ANSI) and therest of the world (ITU-T, formerly CCITT) evolved from different basic-rate signals in thenon-synchronous hierarchy.

Digital subscriber line access multiplexer A digital subscriber line access multiplexer (DSLAM, often pronounced dee-slam) is a network device, often located in telephone exchanges, that connects multiple customer digital subscriber line (DSL) interfaces to a high-speed digital communications channel using multiplexing techniques.Contents.he DSLAM acts like a network switch since its functionality is at Layer 2 of the OSI model. Therefore, it cannot re-route traffic between multiple IP networks, only between ISP devices and end-user connection points.

CCNP Self-Study: Understanding and Implementing Quality of Service in Cisco Multilayer Switched Networks The Catalyst 4000 and 4500 families of switches running Cisco IOS do not prefix QoS configuration commands with the keyword mls. For example, to configure an interface to trust DSCP on the Catalyst 4000 and 4500 families of switches running Cisco IOS, the command is qos trust dscp instead of mls qos trust dscp.

DSL Stands for Digital Subscriber Line.. DSL is a communications medium used to transfer digital signals over standard telephone lines. Along with cable Internet, DSL is one of the most popular ways ISPs provide broadband Internet access. When you make a telephone call using a landline, the voice signal is transmitted using low frequencies from 0 Hz to 4 kHz.

NTU method From Wikipedia, the free encyclopedia. (Redirected from NTU Method). The Number of Transfer Units (NTU) Method is used to calculate the rate of heat transfer in heat exchangers (especially counter current exchangers) when there is insufficient information to calculate the Log-Mean Temperature Difference (LMTD).n heat exchanger analysis, if the fluid inlet and outlet temperatures are specified or can be determined by simple energy balance, the LMTD method can be used; but when these temperatures are not available The NTU or The Effectiveness method is used.

WHAT DOES DSL STAND FOR? Best Answer: Digital Subscriber Line When you connect to the Internet, you might connect through a regular modem, through a local-area network connection in your office, through a cable modem or through a digital subscriber line (DSL) connection. The company that offers DSL will usually provide the modem as part of the installation. But there are disadvantages: * A DSL connection works better when you are closer to the provider's central office. The farther away you get from the central office, the weaker the signal becomes.

- DSL (Digital Subscriber Line) is a technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines..Lite (also known as DSL Lite, splitterless ADSL, and Universal ADSL) is essentially a slower ADSL that doesn't require splitting of the line at the user end but manages to split it for the user remotely at the telephone company. This saves the cost of what the phone companies call the truck roll..

PLC SCADA SCADA (supervisory control and data acquisition) is a system that operates with coded signals over communication channels so as to provide control of remote equipment (using typically one communication channel per remote station).ata acquisition begins at the RTU or PLC level and includes meter readings and equipment status reports that are communicated to SCADA as required. Data is then compiled and formatted in such a way that a control room operator using the HMI can make supervisory decisions to adjust or override normal RTU (PLC) controls.
