Simulation of Telephone System

Problem 1:

The system has a number of telephones (8 are shown) connected to a switchboard by lines. The switchboard has a number of links which can be used to connect any two lines, subject to the condition is that only one connection at a time can be made to each link. They established maximum 3 links.

Process a given number of calls and determine what proportions are successfully

Completed
Blocked or
Found to be busy

The system is lost call system

A call is lost, if the call party is engaged, then it is a busy call
A call may be lost if no link is available, it is blocked call
