1. Illustrate the telephone network model with a neat diagram
The structure of a telephone network is depicted in the figure below. Trunk is a logical link
between two switches-and may traverse one or more physical links that is the end office or
Class 5.
The end office is the lowest in the hierarchy, is the local switching office. The dedicated link
“loop” connects telephone and the end office.
The remaining four higher levels of switches, from Class 4 to Class 1 are tandem or toll switches
carrying toll (long-distance) calls. Now a day due to modern technology these four levels are
merged together and referred to as class 4.
A direct trunk connects two end offices, a tall-connecting trunk connects an end office to any toll
office. and a toll trunk connects any two toll offices.
The direct distance dialing (DDD) network, enables the user to dial far-end telephone with
assistance of an operator. It comprises following 3 transmission trunks:
● A direct trunk connects to end offices
● A toll connecting trunk connects an end office to any toll office
● A toll trunk connects any to toll offices
A circuit connection is set up either directly using a local trunk or via the higher level switches &
routes.
Primary & secondary routes are already programmed into the switch. If the primary route is
broken or the facilities over the primary route are filled to capacity, an alternative route is
automatically assigned.
Operations support systems ensure the quality of service in the telephone network.
NOCs (Network Operations Center) are available in all regions to monitor the global status of
the network. Hence the NOCs are considered as center of a telephone network operations.
