Description

The ISDN_CONNECT_B3_T90_ACTIVE.ISDN_IND message consists of one M_PROTO(D7str) message block indicating switching from T.70NL to T.90NL within a logical connection of a B channel. The ncci parameter identifies the connection; The ncpi parameter transfers additional T.90 information.

This message will only be generated if the selected protocol is T.90NL with compatibility to T.70NL according to T.90 Appendix II. In this case, the protocol initially in use is T.70, and the message indicates the negotiation and switching to T.90.

Parameters

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