Description

The ISDN_CONNECT.ISDN_IND message consists of one M_PROTO(D7str) message block containing the indication of an incoming call for a physical connection. The incoming call is assigned a PLCI (Physical Link Connection Identifier) that is used to identify this connection in subsequent messages.

To activate the signalling of incoming calls, the ISDN_LISTEN.ISDN_REQ(D7isdn) message must be sent to the controller.

Any information available from the network at this point will be signalled to the application. Empty structures show the absence of this information.

Parameters

plci: Physical Link Connection Identifier; see isdnPLCI(D4isdn).
cip: Compatibility Information Profile value; see isdnCIPvalue(D4isdn).
calledNbr: Called party number; see isdnCalledNbr(D4isdn).
callingNbr: Calling party number; see isdnCallingNbr(D4isdn).
calledAddr: Called party subaddress; see isdnCalledAdr(D4isdn).
callingAddr: Calling party subaddress; see isdnCallingAdr(D4isdn).
bc: Bearer capability; see isdnBC(D4isdn).
llc: Low Layer Compatibility. See isdnLLC(D4isdn).
hlc: High Layer Compatibility; see isdnHLC(D4isdn).
info: Additional information elements; see isdnAddInfo(D4isdn).
