The connect request message is used by the application to request establishment of a connection (SCCPConnectRqst) or acceptance of an incoming connection (SCCPConnectResp) when employing the SCCP connection-oriented services (class 2 or 3). This message is also received by the application to indicate an incoming connect request from a far end point (SCCPCONNIND) or to indicate an incoming connect confirmation from a far end point (SCCPCONNCFM).
