Telex Communications 47
Port Alpha
Ports are the individual channels that devices are connected to within the intercom system.
Devices can include:
•
2-way communication devices, such as keypanels, belt packs etc.
•
Audio sources, such as broadcast feeds or background music
•
Miscellaneous audio output devices, such as powered loudspeakers, PA systems etc.
Communication between Ports
The audio signal from any input port can be routed to any output port. For example, during keypanel setup, you
assign keypanel keys so that keypanel operators can talk and listen to other intercom ports. Communication of this
type is called point-to-point communication. You can also route signals between intercom ports without keypanels.
One way to do this is to force crosspoints in the Crosspoint Status screen. For more information on Crosspoint Status,
see Crosspoint Status. Another way to do it is with a GPI input.
Port ID Numbers and Alphas
Intercom ports have identification numbers 001, 002 etc. These numbers cannot be changed.
Each intercom port also has a default name, called an "alpha". This name appears in the alphanumeric displays on
keypanels when you assign the ports to keys for talking and listening. The default alpha names are N001, N002 etc.
These default alpha names can be changed to ones that are meaningful to keypanel operators using Port Alpha
setup.
