How to Monitor SIP over Ethernet

Monitoring IP channels is one of the basic features of the Clarinet.

Connecting the unit

The Clarinet Book USB Ethernet 10/100 uses the RJ45 or AUI port.

The Clarinet Book can be connected to a 10B2 BNC connctor by using:-

• An external transceiver (provided as an accessory) AUI-10B2.
• The power supply of the Clarinet Book, which provides the power to the transceiver.

Setting the test conditions for Ethernet RJ45

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

• LAN application.
• Profile with a description including LAN, Monitor, PH=10/100BT
• Filter with a description including DL= MAC802.3/Auto/SIP

Example using the wizard:-

• Profile=>New=>LAN=>lan_mon.acp=>Filter?=>Lan_auto_sip.acf

The profile created by the wizard is ready for SIP monitoring over Ethernet RJ45 10M or 100M (automatic detection) .The SIP protocol is automatically decoded if the filter is invoked by the profile.

Acquisition limited to a set of MAC addresses

The profile can be modified to only generate events from a set of MAC addresses:-

• Edit the profile created by the wizard (lan_mon.acp as an example).
• Go to Monitored Address:-
  • set the value of source and destination in the columns source address and destination address
• Save the profile under a new name:-
  • Profile=>Save as=>filename.acp.

Running the profile

To launch the profile:-

• Select Profile=>Run or click . you will be able to select the name of profile (see Running a test).
• The Event Editor window is opened automatically.

To stop the profile:-

• Click (see: Stopping a test).
• The Event Editor window is closed automatically.

Troubleshooting over Ethernet

• No messages are displayed in the Event Editor window. Check whether the Clarinet Book LEDs show activity over the LAN interface.
