6. 4. 3. 2 Call to the public Network via a Key Telephone
Dialling via a line key on a key telephone routes the call via the allocated KT route The
KT route is entered in the call distribution element of the KT line.
The call charges can be logged (among others) at the KT cost centre. The KT cost
centre is entered in the call distribution element of the KT line (for more information on
call charge allocation see page 262
).
[1] One and the same trunk group cannot contain both analogue and digital network interfaces.
