Actually...
Don't put authentication into systems that don't need it. It looks to me as if that's a username/password combo for routing the appropriate signalling information to that particular workstation. That is, the signalman for that area always goes to that workstation, rather than the signals following the user to whatever workstation he logs in at.
If that's the desired configuration it shouldn't require the user to enter it at all!
