How to Transfer TSs to TRANSIT over an E1/T1 Trunk

The digital matrix relative to the TS's allows to permanently transfer TS directions between the Current interface and the TRANSIT interface:

Connecting the unit

See the pictures in the 'How to connect E1/T1 interface to Clarinet-Book USB' page.

The TRANSIT connection and the list of signals is described in 'Connections: TRANSIT - Interface signals'.

Setting the test conditions for Trunk E1/T1 simulation

A new profile can be created with the Wizard from the Template list by selecting:

  • Trunk application.
  • Profile with a description including Trunk, Simu, PH=E1 or T1, DL=BERT
  • Filter with a description including DL=Bert

Profiles resulting from the wizard are ready for Bert Simulation over the B channel number 1.

Example: Modifications to transfer TS directions To/From the Transit

In the profile go to Interface-Spec... ->To Transit to define the TS number in the INPUT direction of the Current interface which will be transferred to a TS number in the OUTPUT direction of the TRANSIT port:

  • Enter the From TS number of the Current interface below each To TS number of the TRANSIT interface

In the profile go to Interface-Spec... ->From Transit to define the TS number in the INPUT direction of the TRANSIT port which will be transferred to a TS number in the OUTPUT direction of the Current interface:

  • Enter the From TS number of the TRANSIT interface below each To TS number of the Current interface.

The Current Interface and TRANSIT interface share a common type (E1 or T1) and common Options on the Clarinet-Book USB.

Application: User simulation - Transferring TS 5 of the Current interface to TS 7 of the Transit

Profiles resulting from the wizard are ready for Bert Simulation (User simu) over the B channel #1.

  • Connect the E1/T1 cable to port B (From Network)
  • Connect the TRANSIT cable to port A (From User)
  • Go to Interface-Spec... ->To Transit.
    • Below 'To TS' = 7 enter the value 5 in the From TS' field.
  • Go to Interface-Spec... ->From Transit.
    • Below 'To TS' = 5 enter the value 7 in the From TS' field.

Application: Network simulation - Transferring TS 12 and 13 of the Current interface to TS 18 and 19 of the Transit

Profiles resulting from the wizard are ready for Bert Simulation (Network simu) over B channel number 1.

  • Connect the E1/T1 cable to port A (From User)
  • Connect the TRANSIT cable to port B (From Network)
  • Go to Interface-Spec... ->To Transit.
    • Below 'To TS' = 18 enter the value 12 in the From TS' field.
    • Below 'To TS' = 19 enter the value 13 in the From TS' field.
  • Go to Interface-Spec... ->From Transit.
    • Below 'To TS' = 12 enter the value 18 in the From TS' field.
    • Below 'To TS' = 13 enter the value 19 in the From TS' field.
