I have a quick question. What is the panel just under the ADFs in the picture? It is the one with the blue call light on it. What is it used for?

That is the ATSCALL Decoeder panel, an improved version of SELCALL.

Usually used by dispatch or maintenance control. Can call one a/c, a select group of planes, or the entire fleet using "All Call" mode. Blue light rings and flashes, pilot answers and is able to talk over the VHF or HF Comm.

Yes, it's an ATSCALL decoder...

At SWA, MX doesn't use it, as the dispatcher is the only one capable of initiating contact with the aircraft. The station folks don't use it either. Also, SWA doesn't use it for groups/fleets of aircraft, just each individual tail number.

As an aside, the -300s/-500s/-700s are scheduled to have the ATSCALL boxes yanked out once ACARS installations are complete on these aircraft. When that happens, the dispatcher will simply send a message to come up on a specific location/frequency, and they'll then converse via voice. The -200s will keep their ATSCALL stuff until they're retired, with the last ones going in 2005.
