Can't speak for Brize but Lyneham is slightly different to the one man band system that civil units work to. Weekdays they will have a zone controller, approach controller, director, and talkdown. Weekends it will be approach and zone. Plus an assistant in there too.
Brize will be similar, but often with a capacity to open up two consoles on the Brize Radar side too - oh for that kind of staffing

The AFTN is the teletype system that transmits flightplan data and other airmove messages, not the phone system.
