2.1.2 Signalling on the Call Keys
The LEDs and symbols on the call keys indicate the following states:
2.1.3 Manual or Automatic Trunk Line Seizure
If you hear an external dialling tone when you lift the handset, your telephone is
set to
automatic
trunk line seizure. If you hear an internal dialling tone when you
lift the handset, your telephone is set to
manual
trunk line seizure. You will find a
representation of the audio signals on the inside of the back cover.
If your telephone is set to
manual
trunk line seizure, all call keys on your telephone
first seize an internal line, and you can dial an internal number straight away. When
making external calls, you must first press the trunk line seizure code digit (pre-
setting: ).
Your system administrator configures this code digit for all subscribers on the
OpenCom 100/OpenCom X300 system and will tell you what value is currently
valid.
Note:
This also applies to all enquiry calls and forwarding to
external destinations, but not to “Divert MSN”.
