The Plain Old Telephone Service Is a Good Example of What Kind of Wan Technology?

Similarly, What is a local loop or last mile?

The local loop (also known as the local tail, subscriber line, or the final mile) is the physical connection or circuit that links the customer’s demarcation point to the edge of the common carrier’s or telecommunications service provider’s network in telephony.

Also, it is asked, Is a router a CSU DSU device?

A router is regarded as a CSU/DSU. On the customer’s side of the connection, T-Carrier lines only need a CSU/DSU. IPv4 and IPv6, as well as other network layer protocols, are supported by Multiprotocol Label Switching (MPLS).

Secondly, Is a PVC packet switching technology that offers WAN?

WAN communication via a fast, reliable digital connection using PVC packet-switching technology. Because error checking is done on endpoint devices rather than on the digital channel, throughput is frequently enhanced. Permanent virtual circuits are a subset of permanent virtual circuits (PVCs).

Also, What multitasking did older OS use?

Multitasking was cooperative, as it had been in previous MacOS versions (though unlike Multi-tasking DOS 4. x, which sported pre-emptive multi-tasking). In order to schedule a different job, a task required to surrender to the OS.

People also ask, What does the ping message destination host unreachable message mean quizlet?

What does “Destination net inaccessible” indicate in ping? The destination network does not exist, according to a router on the path from the source to the destination.

Where are MPLS labels placed within a frame?

The label stack is placed in front of the Layer 3 packet, after the Layer 2 header but before the transmitted protocol header. Because of its location, the MPLS label stack is often referred to as the shim header. Figure 2-3 depicts the label stack positioning for labeled packets.

What is DSU networking?

A Digital Service Unit (DSU) is a piece of hardware that uses a Channel Service Unit to link a Local Area Network (LAN) to an external communication carrier service (CSU). A DSU is a device having two or more ports, one of which is marked as WAN and the other as DTE.

What is CSU and DSU in networking?

Description A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device the size of an external modem that translates digital data frames from a LAN’s communications technology into frames suitable for a wide-area network (WAN) and vice versa.

  What Is a Potential Disadvantage of Technology for an Employee?

What is the difference between CSU DSU and a modem?

The CSU/DSU is a device that converts digital signals from a router to a network connection like a T1. A modem is a device that converts digital impulses over a standard telephone connection. Regards. The CSU/DSU is a device that converts digital signals from a router to a network connection like a T1.

What are SVC and PVC?

Virtual circuits are divided into two types: PVC and SVC. “Permanent Virtual Circuit” means for “Permanent Virtual Circuit,” while “Switched Virtual Circuit” stands for “Switched Virtual Circuit.” In networks such as Frame Relay and X, both PVC and SVC play a key role. They’re also found in automated teller machines (ATMs).

What is the difference between a switched and a dedicated WAN?

Traditional switched networks are substantially slower than direct connections. In the search for storage bandwidth, software-defined networking with dedicated connections may assist. We’re searching for methods to maximize box-to-box intercommunication while we look for appropriate bandwidth.

What is PVC in networking?

In a network like a frame relay network, a permanent virtual circuit (PVC) is a software-defined logical link.

What is multitasking in network?

In an operating system, multitasking refers to the ability for a user to do many computer tasks (such as the execution of an application software) at the same time. The operating system can keep track of where you are in each of these jobs and switch between them without losing data.

What are the types of network operating system?

The peer-to-peer NOS and the client/server NOS are the two most common kinds of network operating systems: Users may share network resources kept at a shared, accessible network place using peer-to-peer network operating systems. All devices are considered similarly in terms of functionality under this design.

What is multitasking and its types?

Only one CPU is engaged in multitasking, but it changes from one application to another so fast that it seems to be running all of them at the same time. Preemptive and cooperative multitasking are the two most common forms of multitasking.

What is the IEEE standard that governs all forms of Ethernet media and interfaces?

IEEE 802 is a set of standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs) developed by the Institute of Electrical and Electronics Engineers (IEEE) (MAN). These standards are maintained by the IEEE 802 LAN/MAN Standards Committee (LMSC).


MPLS and Ethernet are the two most prevalent wide area network (WAN) connection choices.

What is MPLS technology?

What Does MPLS Stand For? To manage forwarding across private wide area networks, Multiprotocol Label Switching, or MPLS, is a networking technology that routes traffic using the quickest path based on “labels” rather than network addresses.

What is MPLS with example?

MPLS (multiprotocol label switching) is a network connection speeding method that was initially developed in the 1990s. Packets are forwarded from one router to the next until they reach their destination on the public Internet.

Are CSU DSU still used?

External CSU/DSUs have therefore vanished, even for circuits that need them, and circuits that require them have been replaced with lines terminated with customer-side devices having ethernet interfaces.

What is traditional channel service CSU?

A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device the size of an external modem that translates digital data frames from LAN communications technology to WAN communications technology and vice versa.

What is the function of DSU Why is it important?

The DSU’s job is to send serial data from the WAN port to the DTE ports in a synchronized manner. The DSU allocates DTE data to time slots (channels) on the WAN side if more than one DTE port is utilized.

What is used to set up the CSU DSU?

A channel service unit (CSU/DSU) is a digital-interface device that connects data terminal equipment (DTE), such as a router, to a digital circuit, such as a Digital Signal 1 (DS1) T1 line.

  What Is Technology Product Management?

What is a T1 CSU?

T1 CSU ACE is a full-featured T1 channel service unit that connects T1 data terminal equipment (DTE) to T1 facilities. Alarms, loopbacks, signal regeneration, line build out, and surge protection are all features of the device. The device may be mounted on a wall or used on a desk.

What is Frad in frame relay network Mcq?

FRAD (Frame Relay Assembler/Disassembler) is an acronym for Frame Relay Assembler/Disassembler. It transforms packets into frames for transmission across Frame Relay Networks. It works on the bodily level.

What is ATM Internet?

Asynchronous transfer mode (ATM) is a switching mechanism used by telecommunication networks to pack data into tiny, fixed-sized cells using asynchronous time-division multiplexing. Unlike Ethernet or the internet, which employ changeable packet sizes for data or frames, this method uses fixed packet sizes.

Is virtual circuit same as physical connection?

Virtual circuit switching is a packet switching technique that establishes a conduit between the source and the ultimate destination via which all packets during a call are routed. Because the link looks to the user to be a dedicated physical circuit, this method is termed a virtual circuit.
