telephone antenna (A2/49a1) 

The received telephone signals are amplified by the integrated antenna amplifier. The antenna amplifier is supplied with power by the coaxial antenna cable (phantom feed). The amplified signals are forwarded to the telecommunications control unit (N112) (with code (383a) fixed installation telephone Tele-Aid) or the emergency call system control unit (N123/4) (with code (359) TELE AID emergency call system) via the coaxial antenna cable.

GPS antenna (A2/49a2) 

The received satellite signals are amplified by the integrated antenna amplifier. The antenna amplifier is supplied with power by the coaxial antenna cable (phantom feed). The amplified signals are forwarded to the antenna splitter (A2/5) via the coaxial antenna cable. The antenna splitter (A2/5) distributes the Global Positioning System (GPS) signal to the navigation processor control units (N41/1) and telecommunications control unit (N112) (with code (383a) fixed installation telephone Tele-Aid) or emergency call system control unit (N123/4) (with code (359) TELE AID emergency call system).
