E1/T1 (Trunk/ISDN/QSIG/SS7) & ISDN-BRI Interface Specifications

- SIGNALLING LINK

Emulation mode: Behaviour on SL selected from a list:-

  • Analysis only: Monitoring of BOP events on SL.
  • Simulation and analysis: Simultaneous monitoring of BOP events and simulation on SL.
    •

    Channel specification: TS allotment for SL (only for E1/T1)

  • TS time-slot: Selection of the TS whose TRANSMIT direction is alloted to SL.
  • RS time-slot: Selection of the TS whose RECEIVE direction is alloted to SL.
    •

    Idle mode: Filling between frames on SL

  • Mark idle: 'Permanent 1' after one closing FLAG
  • Flag idle: Continuous HDLC FLAGS.
    •

    Use CCITT #7 protocol: Structure of data used to record the events monitored on SL.
    In simulation mode, data type used on SL.

  • No: The standard HDLC frame envelope mode. One BOP event is generated for each frame.
  • Yes: The specific SS7 protocol mode, event generation is carried out with processing of the frame repetitions.
    •

    56K rate adaption:

    • No: The selected TS is used as 64Kbits data channels.
    • Yes: The selected TS is used as 56Kbits data channels.
