Busy Lamp Field (BLF)
A Station on a Networked System can program the appearance of a Busy Lamp Field (BLF)
status on other Stations in the Networked System. The BLF button can also be used to make a
Net Call to another Networked Station.
To use BLF service, the manager software, and PC application, must be installed from a PC. The
Gate Keeper is the PC server that is installed with the BLF manager software for operational
purposes.
The BLF manager software periodically receives the status of Station from whole system.
Note:
The UDP port will be used to send the status information, and TCP port will be used to
send other information.
The BLF manager software sends the broadcast message to the whole System when the status
changes.
Conditions
•
The BLF manager software should be installed on one System for the whole Networked
System.
•
The number of Net DSS can be restricted according to the capability of each System.
•
When a flexible button on a Station is assigned as the [NET DSS] button of another
system, the System serves as local BLF to indicate the status of the Station.
•
CO BLF is not supported, and also the ringing signal does not update the status of that
Station - ICM / CO / Transfer / CO Recall ring.
•
When a Station is in DND mode, the [NET DSS] button will flash.
•
If the BLF manager does not exist, BLF services can be activated between only two
Systems. The address of the Gate Keeper should be registered on each System.
