Terminating KT Lines and through KT Lines
Any number of line keys from different key telephones can be allocated to the
same KT line. If only one key telephone is allocated to one or several identical KT
lines, we talk of a terminating KT line (TL). If several line keys of different key tele-
phones are allocated to the KT line, we talk of a through KT line (THL).

Through and terminating KT lines
Note:
Unlike call forwarding to terminating KT lines, call forwarding to through
KT lines are not carried out.
Tip:
Calls to through KT lines are normally answered by substitution by the
other connected key telephones.
A destination assignment in the configuration of the call distribution ele-
ment depending on the switching position of the switch group can be
used to achieve an overflow for connections on a through KT line. For
example Call Forwarding on No Reply to general bell or the operator con-
soles can be configured in combination with a delayed user group.
