The DSU provides a modem-like interface between the computer as Data Terminal Equipment (DTE) and the CSU. The 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- carrier line it will also manage timing errors and signal regeneration.
The Channel Service Unit (CSU) receives and transmits signals from and to the WAN line and provides a barrier for electrical interference from either side of the unit. The CSU can also echo loopback signals from the phone company for testing purposes.
What else can I help you with?
A device is required to complete the connection between router R1 and the WAN Which two devices can be used for this?
CSU/DSU Modem
What device acts as a high-speed modem for a LAN?
Csu/dsu
What are the basic roles of a range of interconnection devices and Describe?
• A CSU/DSU terminates a digital local loop.• A modem terminates a digital local loop.• A CSU/DSU terminates an analog local loop.• A modem terminates an analog local loop.• A router is commonly considered a DTE device.• A router is commonly considered a DCE device.
Which two devices can be used by teleworkers who need to connect to the company network across the PSTN for a few hours a day?
CSU/DSU DSL modem
Which device is used to connect a router to a T1 line?
CSU/DSU hardware device (Channel Service Unit/Data Service Unit)
What is the purpose of a csu dsu?
Known fully as a Channel Service Unit/Data Service Unit, a CSU/DSU is meant to function as a device that connects routers to a T1 line. The CSU works by connection to a telecom network and the DSU handles the interface with the Data Terminal Equipment, or DTE.
Full form of CSU DSU?
Data Service Unit
What connects to a four-wire line provided by telco?
Csu/DSU
Which device is used to establish the communications link between the customer equipment and the local loop for digital lines?
CSU and DSU
What the wan service provider calls your collection of equipment including the router and csu dsu?
serial interface
Which physical connector type is used for a serial V 35 connection to the CSU DSU?
Winchester 15 pin connector
For digital lines which device is used to establish the communications link between the customer equipment and the local loop?
For digital lines the device that is used to establish the communications link between the customer equipment and the local loop is CSU/DSU. The call setup time of a circuit switched WAN implementation considered a drawback is data cannot be transferred until a circuit has been established.
