Description

System architecture

W-AIR is a Wildix cordless solution. The system supports auto-provisioning enabling instant connection to the Wildix PBX. Due to high scalability, new components are quickly and easily integrated to guarantee the better performance.

Wildix W-AIR system uses the wireless technology CAT-iq (Cordless Advanced Technology – Internet quality). 

The architecture consists of three components:

1. Base station - an essential component of a DECT system. Wildix W-AIR base stations:

• Multicell base stations: W-AIR Base (End Of Life), W-AIR Base Outdoor, W-AIR Base Sync Plus
• Single Cell base station: W-AIR Base Small Business

2. Repeater - extends the signal coverage of the base station.

3. Cordless endpoints:

Wildix W-AIR handsets: W-AIR Basic (ex W-AIR 70), W-AIR 100 (End Of Life), W-AIR LifeSaver (ex W-AIR 150), W-AIR Med, W-AIR Office and W-AIR Headset. Follow the online Guides to get detailed information: W-AIR DECT Handsets Guide, W-AIR Headset Guide.

You can check the Delay and the Jitter on the base station's interface, menu LAN Sync:

Expected jitter levels for different types of switches:

• Fix parts connected to Aruba HP switch will have expected jitter < 300ns
• Fix parts connected via 3 layer switch will have expected jitter < 500ns
• Fix parts connected via 7 layers switch will have expected jitter < 2000ns

1. Go to the menu Extensions

2. Click on the field “Idx” or “Extension” of the handset:

   
   

3. The following window is displayed, allowing you to set up emergency settings:

   
   

4. Modify the parameter “Alarm Number”: enter the number to be called when the alarm is triggered from the handset:

   Go to Management menu and click Save and reboot to reboot the base station and apply the new parameters

   Note
   You can enter an extension number that must be called or customize the service by modifying the Dialplan in the WMS and to add the “Alarm Number” as a Called number into a Dialplan procedure.

5. Tick off the Profiles that you wish to enable for this handset

6. Click Save at the bottom of the page

7. to add the “Alarm Number” as a Called number into a Dialplan procedure.

   
   

8. Tick off the Profiles that you wish to enable for this handset

9. Click Save at the bottom of the page

10. Go to Management menu and click Save and reboot to reboot the base station and apply the new parameters

Statistics

Menu Statistics, accessible via base station web interface, offers access to four administrative menus, allowing the system administrator to monitor:

• System
• Calls
• Repeater
• DECT data
• Call quality.

System data

Free running explained

Free running is NOT an error state, but is a simple trigger state, indicating that some changes have to be made to ensure continuous DECT synchronization.

Free running tells the application that the base has not received any sync data from its sync source base station during the last 10 seconds.

The reasons for this behavior can be the following:

1. Two bases are using the same DECT slot and therefore cannot see each other.
2. Too many simultaneous calls.
3. A sudden change of environment (e.g. closing a fire door)/.
4. Distortion of DECT frequency (around 1.8MHz) either by other DECT systems or other equipment.

When the Free running state is trigged the following actions are recommended:

1. Move DECT slot to avoid using the same DECT slot as another base as its synchronization source base state.
2. Use information from other base stations, to check how they are seeing this base station in the DECT air.

Free running activates several recovery mechanisms: the state changes to Assisted lock. The state Assisted lock can remain stable for a long time and normally changes to state Locked again. The state Free Running can also change back to state Locked again.

If the base is in state Free running and the synchronization source base station cannot be seen and no data is available for the assisted lock mechanism, the base station will change to a new state after 2 minutes:

1. If the base station does NOT have any active calls, the base will change to state Searching.
2. If the base station has an active call, this base will change to state Sync lost. After the call is released, the state will change to state Searching.
