17.74. TCET - Through-connect a networking transit connection
after call extend in call status 
Feature:
Dial tone after transfer in call status
Function:
After an external consultation connection has been transferred in call status to an
externally held partner, the resulting transit connection between the waiting party
and the
consulted party is through-connected.
Requirements: The trunks involved in the resulting transit connection must be
networking trunks and theTCET parameter must be activated in the COT of the waiting
trunk.
IMPORTANT:
The through connection function is only executed if the CHRT parameter
is not activated in the COT of the waiting trunk!
AMO Interrelationships:
COT Class of Trunk
CHRT With unscreened transfer, ringback tone should be supplied instead of hold tone
Device types:
Networking trunks .... digital CO trunk circuits, interface circuits and tie trunk
circuits
and analog NW trunks
For example, SOCOD, S2COD, SOCONN, S2CONN, etc.
