Question

Wilke’s IT manager appreciates how clearly you explained each WAN connectivity option. The firm has decided to implement nearly everything you recommended, including T1s and T3s connecting all the regional offices and broadband DSL connections for every employee who works from home. Before the firm solicits bids for equipment and carrier services, the IT director asks you to sketch a simplified network diagram, with each type of WAN link labeled. He also requests that you identify, for each link, the kind of medium it will use and provide examples of the equipment necessary to complete each connection in an office and at an employee’s home.

Answer 1

Answer:

• On the Diagram, we can see the Head office (There is the primary server of the WAN).
• The administrative center is associated with all the territorial offices utilizing T-bearer transmission (T1 and T3). The local offices are associated with 150 home working employees utilizing DSL association (utilizing balanced transmission).
• As a medium, we are utilizing Splitter, DSL modem, Workstation, and telephone. Likewise, we will utilize a coaxial link and RJ45 jacks.
• For T1 transmission we are utilizing the Router with internal CSU/DSU and multiplexer. T1 innovation can utilize UTP or STP (unshielded or protected twisted pair) copper wiring as it were, plain phone wire coaxial link, microwave, or fiber-optic link as its transmission media.
• Be that as it may, in light of the fact that the computerized signals require a spotless association, STP is desirable over UTP. At the point when copper cabling is utilized to convey T1 traffic, it ends in an RJ-48 connector.
