4.6. DLINK_CFG

The DLINK_CFG structure contains information about the data link logical link configuration block. The DLINK_CFG structure is retrieved using the cc_GetDLinkCfg( ) function.

The structure is defined as follows:

 typedef   struct   
{
    char  tei;
    int   state;
    int   protocol;
}  DLINK_CFG,   *DLINK_CFG_PTR;

Table 45. DLINK_CFG Field Descriptions

Field	Description
tei	Terminal Endpoint Identifier. Valid values are: 0 - 63 - for manual TEIs (chosen by the user side) AUTO_TEI - for automatic TEIs (chosen by the network side)
state	The original state in which the logical link should be configured. Valid values are: DATA_LINK_UP - the firmware will attempt to activate the logical link if it is not already activated and will allow the network side to establish the logical link if requested. DATA_LINK_DOWN - the firmware will attempt to release the logical link if it is currently established. The firmware will allow the network side to establish the logical link if requested. DATA_LINK_DISABLED - the firmware will attempt to release the logical link if it is currently established. The firmware will not allow the network side to establish the logical link if requested.
protocol	The protocol to be used on this logical link. For instance: DATA_LINK_PROTOCOL_Q931 - indicates that the link is to be used as an ISDN connection-oriented logical link. DATA_LINK_PROTOCOL_X25 - indicates that the link is to be used as an X.25 packet-switched link.
