The Dte Or Endpoint Device For A Leased Line Is Known As Which Device Below?

The Dte or endpoint device for a leased line is known as which device below?

A leased-line is a telecommunications circuit connected to two or more locations. It is specifically used by different offices present in a different region of the world means separated by geographic distance. It is a personal communication system based on commercial contracts in a different location in a geographic region. It is used for the business to connect different offices in different geographic regions.

The leased line is not needing a number and does not have switched circuit. Other telephone numbers are connected to the public switched telephone network. The leased line is every time active and permanently connected to each line. It can be used in different ways like telephone, internet. The main factor which has a direct effect on the leased line is the area between the bandwidth and end stations. It is a straight connection between two different locations there is no interference of the third party so is to make assure the level of quality.

The premium leased line is the internet leased line, it is transmitted through optical fiber, it ensures the level of quality and symmetrical, undistributed bandwidth. It is also called a private line and dedicated line.

Application of leased line:

The function of the leased line is to fully access the other partner network and telephone network or internet network. Here is some applications of the leased line are discussed below.

Site-to-site connectivity:

In 1970 leased lines are used by various enterprises such as research, university, and digital equipment when the internet are not widely available. Network abilities can be spread when the leased line is terminated between two routers.

The site connectivity to the network:

In telephone company more advanced data networks are demanded to establish a reliable network by the use of switch packets on the infrastructure. Based on this demand ATM, more telecommunication companies are added. In this way,  customer site is connected to the telephone company by leased line.

Private international leased circuit:

It is the point-to-point private line. In the international private circuit, all the customers used the same circuit it is the time-division multiplexing circuit. This TDM used the CSU/DSU routers. The advancement of the internet brought other technologies to adopt the alternative such as VPN, MPLS.

The alternative of leased line:

ADSL and SDSL are the alternatives of a leased line. These are less expensive than a leased line because secured by the leaseholder. Various internet service provides alternative to the leased line like zero contention, availability guaranteed. These also provide a moderate bandwidth. The alternative of the leased line is half-duplex whole leased line is of full-duplex. The alternative has the possibility of asymmetrical service while the leased line is asymmetrical service. The endpoint device for a leased line used is GSU/DSU.

What is GSU/DSU:

GSU/DSU stands for channel service unit/data service unit.  Data terminal equipment is connected by this digital device.it includes routers, digital circuits. It represents two, unlike functions.

The channel service unit is answerable for telecommunication network connection. While data service equipment function is to manage the data terminal equipment interface. Both these are connected externally on the circuit.
