How to Simulate V5.2 - LE Side over E1 Interface

Simulation of V5 LE equipment is one of the features of the Clarinet Run-Time.

The Clarinet Book USB E1/T1 which simulates the LE side in front of an AN, uses the A port 'From AN'.

The Clarinet Book can be connected to the E1 interface in:-

Extremity mode over E1. Clarinet inputs set as 75, 120 Ohms. (see: wiring, connect, pin-out).

A new profile can be created from a template, using the wizard, by selecting:-

Example using the wizard:-

Profile=>New=>V5.x=>v52_simu_le_e1_bri.acp=>Filter?=>v5.acf.
Profile=>New=>V5.x=>v52ed2_simu_le_e1_pri.acp=>Filter?=>v5.acf.

The profile created by the wizard is ready for monitoring in the C channels over time slot 16 and 15:-
