ISDN_RESET_B3.ISDN_REQ -- ISDN reset logical connection request

Synopsis

   #include <sys/stream.h>

   typedef struct isdn_reset_b3_req
   {
       isdnNCCI_t   ncci;
       isdnNCPI_t   ncpi;
   } isdn_reset_b3_req_t;

Description

The ISDN_RESET_B3.ISDN_REQ message consists of one M_PROTO(D7str) message block requesting the specified logical connection be reset. The ncci parameter identifies the logical connection.

The reaction to an ISDN_RESET_B3.ISDN_REQ message depends on the layer 3 protocol selected. If ISO 8208, T.90, X.25 DCE or X.25 PLP in the D channel was selected, the reset procedure is performed in accordance with the protocol recommendations. If a transparent layer 3 was selected, a reset procedure in layer 2 is initiated.

If a reset procedure is not defined for the protocol, an ISDN_RESET_B3.ISDN_REQ causes the controller to generate an ISDN_RESET_B3.ISDN_CONF(D7isdn) with the isdnInfo(D4isdn) value set to ISDN_INFOCODE30_RESET (reset procedure not supported). No further action is taken.

After successfully, initiating a reset on a logical connection, an application is not allowed to transmit data until the resulting ISDN_RESET_B3.ISDN_IND(D7isdn) or ISDN_DISCONNECT_B3.ISDN_IND(D7isdn) message is received.

WARNING: Data can be lost during a reset procedure.

Parameters

ncci: Network Control Connection Identifier; see isdnNCCI(D4isdn).
ncpi: Network Control Protocol Information; see isdnNCPI(D4isdn). The meaning of this parameter is protocol-dependent.
