Description

The ISDN_INFO.ISDN_REQ message consists of one M_PROTO(D7str) message block requesting that a Q.931 information frame be sent to the network. This message permits protocol information to be sent for a physical connection (for example, ``overlap sending''.

Parameters

plci: Physical Link Connection Identifier; see isdnPLCI(D4isdn). This parameter identifies a physical connection (if a PLCI is given) or the addressed controller (if the ISDN_PLCIMSK_PLCI field of this parameter is 0). Different messages will be sent to the network depending on the parameter.
calledNbr: Called party number; see isdnCalledNbr(D4isdn).
info: Additional information elements; see isdnAddInfo(D4isdn).
