Telecom

                                                    Basics of Telecom Mobile Communication   Emergency Communication  Emergency Communication is provided by following means a) Emergency Socket b) 5/25 Watt VHF sets c) GSM - R ( very less percentile) d) Mobile phones available with driver, guard and staff. Disadvantage of above mode of Emergency Communication - Section controller is not able to contact train crew in moving train It can be initiated only in static condition SOS facility is not available Weight of emergency control phone is fairly heavy. GSM - R is used at very less percentile. To avoid these Shortcoming MTRC ( Mobile train radio communication) is implemented. Accidents, unusual situation, robbery in train, Locomotive failure and chain pulling etc. Features of MTRC  - Driver to Control Guard to Control Driver to station maste...

Data Communication & Networking

  Data Components - A data communication system has five components. 1.  Receiver  2. Sender 3. Message  4. Transmission media- Path by which message travels. Ex Twisted pair wires, Coaxial cable,fibre optic cable and radio waves 5. Protocol  Protocol is set of rules used by computers to communicate with each other across network.  Protocols can be classified as Proprietary Protocol ( specific make) Open source Protocol ( Any make). Bandwidth -  It is defined as amount of data that can be transmitted into a fixed amount of time. Usually expressed in bps ( bits per   second) Fundamental Characteristics of Data Communication   1. Delivery- System must deliver data to correct destination  2. Accuracy- System must deliver data accurately  3. Timeliness- System must deliver data in a timely manner  4. Jitter- Jitter refers to variation in packet arrival time. It is uneven delay in the delivery of audio and video packets,which r...
