How to monitor V5 protocol over E1 interface

Monitoring the V5 protocol (V5.1 or V5.2) over an E1 interface allows to display the links carried over 2 Time-Slots.

Connecting the unit

The Clarinet Book USB E1/T1 uses the both A and B ports for monitoring the both T and R directions.

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

• parallel mode over E1. Clarinet inputs set as high impedance. See: wiring , connect,  pin-out
• serial mode over E1. Clarinet inputs set as 75, 120 Ohms. See: wiring , connect,  pin-out

The Clarinet-Book can be connected  to the T1 interface in:

• parallel mode over T1. Clarinet inputs set as high impedance. See: wiring , connect,  pin-out
• serial mode over T1 with clarinet inputs set as 100 Ohms. See: wiring , connect,  pin-out

Setting the test conditions to monitor one single E1 Link

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 V5, Monitor, PH= E1, SL=DL=V5
• Filter with a description including SL= DL V5

Profile resulting from the wizard is ready for V5 monitoring in the TS 16 and TS15.

Events of TS15 are displayed with TS/RS attribute, TS16 with TD/RD attribute.

Optional modifications to apply to the profile:

• E1 options: CRC4 multi-frame is normally used over V5 (selected by default )
  Deselect it if not used (Interface SpecsèLinkèOptions).

Saving the profile under a new name:

• ProfileèSave asèfilename.acp.

Running the profile

To launch the profile:

• Select Profile->Run or click over . 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 See: Stopping a test
• The window of the Event-Editor is automatically close

Setting the test conditions to monitor two E1 Links

Following the edition of the profile from the Template duplicate the interface:

• Locate the cursor over the tab "Clarinet 1" over an area trigging the "copy" indication
• Right click over "Copy"
• Select the tab "No Clarinet" and select "Clarinet 2" in "Interface"
• Locate the cursor over the tab "Clarinet 2" over an area triggering the "copy" indication
• Right click over "Paste"
• Save the profile under a new name by "Save as"

Profile is ready for monitoring simultaneously TS 16 and TS15 on the both interfaces.

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.
