How to Monitor a Protocol over One ISDN B Channel

Clarinet Run-time enables monitoring of one B channel simultaneously with the ISDN-D channel over one ISDN-BRI or ISDN-PRI interface.

Connecting the unit and setting the test conditions:

The connections of Clarinet-Book USB units and the settings of test conditions for basic monitoring are detailed in the following pages:

Profiles resulting from the wizard are ready for Q931 or X25 monitoring in the D channel over BRI or PRI. A new filter selected among one dedicated to the protocol used in the B channel should be selected. The description should include SL= Q931 and one of the following options:

  • DL=BOP
  • DL=BOP/Frame Relay
  • DL=BOP/PPP
  • DL=BOP/V120/PPP
  • DL=BOP/X25

The B channel can be a defined by a value or automatically selected.

Example: Modifications to monitor BOP protocol over B channel #2

In the profile go to Interface-Spec... ->Data Link and select:

  • Emulation mode: Analysis
  • Data Link Type: BOP
  • TD Time Slots: 2
  • RD Time Slots: 2

Warning: Any number and value of TS can be selected but the same number of TS's must be selected in TD and RD.

Example: Modifications to monitor B channel defined by IE "Called Party Number"

In the profile go to Interface-Spec... ->Data Link and select:

  • Emulation mode: Analysis
  • Data Link Type: BOP
  • Selecting IE: IE=Called Party number
  • Coding ->
    • Type of Number= Subscriber Number
    • Numbering Plan= ISDN
    • Number digits= 34567890

A system event "DL-Analysis ON" is generated at the beginning of acquisition.
