428 Module - eLOCATION

Program activity

When the startup phase is done, eLOCATION has two permanent socket

connections.

• One socket connection is established with the eKERNEL and is used

to exchange "location requests" and "location reply" data flow.

• The other socket connection is established with the DAP Controller PC

(DCC) and follows a proprietary protocol to retrieve location information

of SIP DECT extensions.

The link with the DAP Controller exchanges data on regular time interval,

so both parties can verify the activity of the remote party. This guarding

is typically represented by the informational message "Data arrival – 1

bytes received from DCC". When the connection is broken, eLOCATION

attempts to reestablish a session.

Note: Define The IP address of the PC that runs eLOCATION in the

PBX. When the IP address is not defined, the connection request is

rejected by the DAP Controller. The two green indicators on the bottom

of the eLOCATION panel illustrate the successful connection state

between both external parties.

Keep track of the progress of the actual location detection process through

the eLOCATION tab. The location detection process takes place when

eKERNEL sends a location request to eLOCATION. The following figure

shows the idle state at system startup prior to executing the first request.
