How to loop TS's over an E1/T1 Trunk

The digital matrix relative to the TS's allows to permanently loop the data from each TS to another TS of the Current interface.

Connecting the unit

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

Setting the test conditions for 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

Profile resulting from the wizard is ready for Bert Simulation over the B channel #1.

Example: Modifications to loop TS's

• In the profile access to Interface-Spec... ->Loop :
• Enter the 'From TS' number below each 'To TS' number that has to be looped.

Application: Looping TS 5 to 7 and 8 to 8

• Below To TS = 7 enter the value 5 in the From TS field.
• Below To TS = 8 enter the value 8 in the From TS field.

The data are looped:

• content of the TS 5 of the input direction will be transmitted in the TS 7 of the output direction
• content of the TS 8 of the input direction will be transmitted in the TS 8 of the output direction
