How to simulate V5.2 - LE side over E1 interface

Simulation of a 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 a 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 with the Wizard from the Template list by selecting:

Example using the wizard:

ProfileèNewèV5.xèv52_simu_le_e1_bri.acpèFilter?èv5.acf
ProfileèNewèV5.xèv52ed2_simu_le_e1_pri.acpèFilter?èv5.acf

Profile resulting from the wizard is ready for monitoring in the C-channels over TS 16 and 15

Modifications to apply to the profile about physical interface:
- E1 options: CRC4 multi-frame is normally used over V5 (selected by default ).
