Description

The incoming call is identified using the plci parameter. The reject parameter is used to accept, reject, or ignore the call. When the call is ignored on a BRI (Basic Rate Interface) bus, other ISDN equipment connected on the bus will have the opportunity to accept the call; when the call is rejected, it is terminated on the entire bus. For the PRI (Primary Rate Interface) bus, the reject parameter values will behave the same.

Parameters

plci

Physical Link Connection Identifier; see isdnPLCI(D4isdn).

reject

Reject; see isdnReject(D4isdn). Any unknown reject value will be mapped to ISDN_REJECT_NORMAL (Reject, normal call clearing). Any reject value other than ISDN_REJECT_OK (Accept the call) will cause an ISDN_DISCONNECT.ISDN_IND(D7isdn) message to be sent to the application.

bProto

B protocol to use; see isdnBproto(D4isdn). The absence of a B protocol value (that is, coding as an empty structure) will result in the default protocol behavior: ISO 7776 (X.75) and window size 7. This selection gets overall connectivity with the benefits of HDLC error recovery. However, ISO 7776 deals with a default maximum data length of 128 octets, while the SCO ISDN implementation can handle at least 2048 octets, depending on the values of the ISDN_REGISTER ioctl called by an application.

ConnNbr

Connected number; see isdnConnNbr(D4isdn).

ConnAddr

Connected subaddress; see isdnConnAdr(D4isdn).

llc

Low Layer Compatibility. See isdnLLC(D4isdn). This parameter can optionally be used for LLC negotiation if supported by the network.

info

Additional information elements; see isdnAddInfo(D4isdn).
