(CAS_EXTern) in a mixed network of OpenScape 4000 systems with older Hicom 300 systems.
Function:
Parameter set (do not send a CINT LEG 2 operation): In the case of the outgoing CAS
EXTernal call signaling, no service intercept operation with LEG2 information is sent;
instead the parameter is transferred in accordance with CorNet-N.
IMPORTANT:
Not to be set in the OpenScape 4000/HiPath 4000 homogenous
network.
The parameter works in an outgoing direction.
The value for the COT parameter must be set for outgoing digital tie trunk circuits
for
Hicom 300 systems.
