  • Page 12: Function And Application

    5. Function and application 5.1. Network element type OPCOM3100-155 is suitable for network end access. It can provide STM-1, E1 and Ethernet access and can be configured as TM, ADM and REG. 1. Terminal multiplexer (TM) The main function of terminal multiplexer (TM) is multiplexing low speed E1 or Ethernet signal to high speed STM-1 SDH signal and demultiplexing high speed STM-1 SDH signal to low speed E1 or Ethernet signal.

    station, and it is compliant with ITUT standard. Every index is compliant with ITUT standard when OPCOM3100 change the recovered clock reference (e.g. if there is LOS) 5.4. Protection switch OPCOM3100 provides 1+1 low path protection in the case that the optical fiber is broken off, PCB is damaged or middle notes are invalid, and the protection switch time will be less than 50ms.
  • Page 16 2. 2F SNC-P: The principle of 2F SNC-P protection is that: “transmit data bi-directionally, receive data bi-directionally, select one better quality signal and use the other signal as standby”. 2F SNC-P uses one fiber to transmit service, called S fiber (working fiber);...
  • Page 17 C anticlockwise though middle station D. C receives two signals bi-directionally and it will select a better quality signal (the signal in working line S fiber generally). Data from C to A is the same process. The Tx and Rx routing is in figure (b) when the fiber is cut off: for the signal in S fiber is lost the switch will shift from S fiber to P fiber to receive the data transmitted by P fiber, so the service between station A and C will go on.
