typedef struct isdn_conn_tab {

char name[ISDN_ID_SIZE]; /∗ identiﬁcation string ∗/

isdn_interface_t type;

} isdn_conn_tab_t;

The table contains a string which is the interface’s uniqueidentiﬁcation string. The

second element of this table contains the ISDN transmit and receive connections and

conﬁguration for all possible data paths for each type of ISDN controller hardware.

Entries that are not connected will have a value of ISDN_NO_CHAN in the from and to

ﬁelds. The number of entries will always be ISDN_MAX_CHANS, and can be referenced

in the hardware speciﬁc implementationdocumentation. An isdn_conn_tab_t structure

is allocated on a per controller basis.
