|The Ensign TX33 terminal design is based on the Viscount telephone and
offers similar facilities to the TX51 terminal with the following additions:-
- 14 Variable function press-buttons.
- Different Keypad layout.
- The P button combines the functions of the P and R buttons on the original terminal,
i.e. it is used when storing "named Intercom" and "Repertory Called"
numbers, and when connected to a PBX to "RECALL" the PBX operator.
- The Monitor amplifier which is provided as standard is automatically cancelled when the
handset is lifted after making a hands free call. Also, unlike previous terminals, if the
monitor button is pressed with the handset off-hook the call is transferred to the monitor
amplifier. Pressing the Monitor button again will transfer the call back to the handset.
- It is not possible to fit facility handsets, or provide a headset socket.
