PXML No. 63
TX54 terminals use electronic speech circuits in conjunction with specialised handset
transducer, therefore it is not possible to fit or use any of the facility handsets
currently available. Also the terminal does not have any Power Failure working capability.
The instrument incorporates a 16 character LCD display, monitor loudspeaker and a headset
jack fitted as standard. Dedicated facility buttons are provided for all standard
facilities. The TX54A terminal was introduced that offered greater immunity to radio
frequency interference and had a slightly different facility button layout.
