Description

The isdnBproto structure and substructures are used to select and define the physical link and framing, data link layer, and network layer protocols. There is a protocol identifier and configuration information for each layer. If this structure is empty, the default values are assumed.

These structures are used by:

ISDN_CONNECT.ISDN_REQ(D7isdn)
ISDN_CONNECT.ISDN_RESP(D7isdn)
ISDN_SELECT_B_PROTOCOL.ISDN_REQ(D7isdn)

Parameters

B1proto: physical layer and framing protocol; see isdnB1proto(D4isdn).
B2proto: data link layer protocol; see isdnB2proto(D4isdn).
B3proto: network layer protocol; see isdnB3proto(D4isdn).
B1config: physical layer and framing parameters; see isdnB1config(D4isdn).
B2config: data link layer parameters; see isdnB2config(D4isdn).
B3config: network layer parameters; see isdnB3config(D4isdn).
