Telecoms Switching Systems & Networks - TSSN Course And Certification
What is TSSN?
Telecommunication Switching Systems and Networks - TSSN is simply the control mechanisms available in Telecoms.
Telecoms or Telecommunication is the exchange of communication between two or more individual via telecom applications and devices.
Switching Systems is the control method used to link calling subscribers and called subscribers together.
The Switching Ssystem is classified into two which are:
1. Manual and
2. Automatic (Electromechanical and Electronic).
Features and Benefits of TSSN:
1. TSSN offers smooth means of exchanging information and communication with the use of control mechanisms.
2. TSSN is an important tool for businesses as it helps to communicate effectively with customers and deliver high standards of customer service.
3. TSSN is a key element in teamwork and project management allowing employees to collaborate easily from wherever they are located.
4. TSSN makes communication process easier for everyone through a long distance.
5. TSSN offers flexibility of work in workplaces.
6. TSSN develops the society at large through smooth communication.
7. TSSN helps to improve teamwork and collaboration and increases business growth.
8. TSSN saves time and cost of operations.
9. TSSN offers lots of job opportunities such as:
+ Broadcasting Technician
+ Network System Analyst
+ Programmer Radio Dispatcher
+ Communication Equipment Operator
+ Data Communication Analyst etc.
Components of Telecommunication Switching Systems:
The components of switching systems are as follows:
1. Switching Network: this provides switching paths between the calling subscriber and called subscriber.
2. Control Subsystem: identifying the inlet and outlet lines and interpreting the signaling information received on a particular line.
3 Signaling: For Signals.
4. Trunk Interface: It's used for connections between the Switching Systems.
5. Subscriber Line Interface: this used for connections between the subscriber and the switching system.
6. Line Scanning Unit: It senses and obtains the signaling information from the different lines.
7. Distributor Units: this used for distributing or sending out signaling information on the various lines.
8. Operator Console: It allows interaction with the switching system for the administrative and maintenance.
9. Service Circuit Interface: this provides interaction between circuit for the purposes of maintenance and testing.
10. Junctures: It provides a folded connection for the local subscribers and the service circuits.
Here we highlight some of the modules you will learn in this course:
The Invention: Alexander Bell invented and demonstrated his set of telephone and possibility of long-distance voice communication in 1876.
Switching System: where the network cannot be simply made with telephone sets and a bunch of wires, but a good system is required to make a break connection which is the switching system, then we talk about the classification of switching system which is Manual and Automatic.
Telecommunication Networks: where we talk about Folded Network, Blocking Network, Switching Network, etc. We talk about Signaling, Trunk interface, Subscriber Line Interface, Junctures, Direct and Indirect Control Switching System.
Strowger Switching System and how it is being operated, talking about Dialing (Pulse Dialing and Rotary Dial Telephone). Moving unto Multi-exchange Network, Common Control System, Exchange Identifier, and Subscriber Identifier.
Touch-Tone Dialing which was introduced in telephone to replace the Rotary Dial. Which on pressing a button on the touch-tone dial phone indicates the number dialed using certain frequencies (touching) and we also talk about DTMF (Dual-Tone Multi-Frequency)
Crossbar Switching Method which was developed in the 1940s and helped in sharing resources, call processing, charging and event monitoring.
SPC (Stored Program Control) which allows Abbreviated Dialing, Call Forwarding, Call Waiting, Do Not Disturb etc. then to Switching Techniques such as Circuit Switching, Message Switching, and Packet Switching.
PSTN (The Public Switched Telephone Network) which is used for providing Public Telecommunication - POTS. Switching Hierarchy and Routing talking about Mesh Topology, Star Topology, and Hierarchial.
Private Branch Exchange (PBX) which can be understood as local exchange within an office, a more private exchange system that switches calls between users on local lines and still allow them to share a certain number of external lines.
The ISDN: which was first defined in the CCITT red book in 1988 and is a network-based infrastructure that allows the transmission of voice and data simultaneously at high speed with greater efficiency. We have several kinds of ISDN interfaces such as the BRI, PRI, Narrowband ISDN, Broadband ISDN etc.
