Yeah, it's a pretty nice facility. Those tower pics are quite out of date - there's been an upgrade to both the terminal and surface movement radar displays, and Clearance Delivery is now in the Tower, replacing the data guy whose job was computerised.
(Don't blame the webmaster for the out of date info, it's not his fault!!)
The terminal radar is now part of the national computerised ATC system (TAAATS), and both it and the SMR are large high res LCD screens - much better than what's shown on the website.
All intercom, hotlines, lighting and radios are controlled through a touch screen system we call VSCMS, with each controller's screen being configured to suit his role. There are 6 positions and we have a standard configuration, but any position can be configured to do any role or combination of roles. This provides multiple redundancy to cover both equipment outages at console positions and staffing changes as traffic winds up and down during the day.
Just in case the computer system goes down, we have a copper wire bypass for each freq that goes direct to the transceivers, bypassing the computer trickery - found the need for that through hard experience.
Backup to the hotlines to the radar unit (which is remote) is copper wire telephone (not permanent lines, you have to dial an extension. That's ok, it's a contingency plan and traffic would be reduced until normal facilities return.) Other telephones go through the VSCMS computers.
The computers at each position are duplicated, A & B, with each being part of an A & B duplicated network. The two networks talk to each other, the active one constantly updating the standby one so that if the active should fail, the standby has the current configuration in RAM and will seamlessly take over.
It's pretty neat. Now, if we could just get our airspace designers to match their output to the quality of the hardware we use to administer it .... (See threads on NAS in Dunnunda)
