Synopsis

   typedef struct isdn_disconnect_b3_req
   {

       isdnNCPI_t      ncpi;
   } isdn_disconnect_b3_req_t;

Description

The ISDN_DISCONNECT_B3.ISDN_REQ message consists of one M_PROTO(D7str) message block containing a request to clear a logical connection. The logical connection is identified by the ncci parameter. The ncpi parameter can be used to transfer additional protocol-dependent information.

If the fax group 3 (B protocol T.30) or speech (B1 protocol bit-transparent, B2/B3 protocol transparent) bearer capabilities are in use, data already prepared for transmission using ISDN_DATA_B3.ISDN_REQ(D7isdn) will be sent before clearing the logical connection.

Parameters

ncci: Network Control Connection Identifier; see isdnNCCI(D4isdn).
ncpi: Network Control Protocol Identifier; see isdnNCPI(D4isdn).
