  • 15. TELECOMMUNICATION  Manufactures EPABX and MAX systems based on C-Dot technology  It is necessary to run a number of internal cables between the following stages and frames:  Handset to exchange’s cable chamber  Cable chamber to M.D.F.  M.D.F. to L.D.F.  L.D.F. to number block  Number block to Exchange Equipment  Between two exchanges  Between two cities  Between two countries
  • 16. Manual & Automatic Telephony  Higher level of secrecy is maintained  No possibility of the calls being missed or wrong metering being done  Running cost of the exchange is reduced
  • 17. ELECTRONIC EXCHANGES  Tone type: In this type of exchange sine wave is used. Their speed of dialling for a given number is more than that of pulse type.  Pulse type: In this type of exchange square wave is used due to which dialling speed is lesser.
  • 18. ELECTRONICS EXCHANGE
  • 19. M.D.F.  Place where both external and internal cables are terminated.  External individual cables carry conductors from subscribers  Internal cable conductors come from apparatus side  Cross section between the two cables is done on the M.D.F. through jumper wires  M.D.F. carries all the protectors used in the exchange:  Fuses  Heat Coils &  Lightening Protectors.
  • 20. Old MDF New MDF
  • 21. L.D.F.  These frames consists of a large number of verticals with horizontal cross arms fitted with tag blocks  The cable from M.D.F. is terminated on the multiple sides & from the exchange side cables run to the line cards  The two tag blocks are joined by jumper wires, so that any subscriber can be given connection to any uniselector on the line card  The subscriber’s uniselector are divided into different groups & these originate the same amount of traffic for smooth distribution.
