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

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

Connecting the unit

The Clarinet Book USB E1/T1 which simulates the AN side in front of a LE, uses the B port "From LE".

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

Creating the profile for V5.2 AN simulation

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

  • Profile->New->V5......See: building
  • Profile with a description including ISDN, Simu, AN, PH=E1 SL=V5.2
  • Filter with a description including SL= V5

Example using the wizard:

  • ProfileèNewèV5.xèv52_simu_an_e1_bri.acpèFilter?èv5.acf
  • ProfileèNewèV5.xèv52ed2_simu_an_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 ).
      Deselect it if not used (Interface SpecsèLinkèOptions).
  • Modifications to apply to the profile about PSTN signalling:
    • Changing the port number: [PSTN User port Emulator config]èPort1è Edit èPort address
    • Changing the dialed number: [PSTN User port Signalling Behavior]è GeneratorèPort1è Edit èDigits

Saving the profile under a new name:

  • ProfileèSave asèfilename.acp.

Running the profile

To launch the profile:

  • Select ProfileèRun or click over horse_on.gif (968 octets) . It allows to select the name of profile. See Running a test
  • The windows of the Event-Editor is automatically opened.

To stop the profile

  • Click over horse_off.gif (975 octets) See: Stopping a test
  • The window of the Event-Editor is automatically close

Troubleshooting over E1

  • No messages displayed on the Event-Editor windows. Check if the Alarms line have an indication such as ' -+ FL' or '++FL' meaning that no signal is detected.
  • The protocol messages are displayed on the wrong directions: the E1 pair connected to the A and B port are the reverse side.
