The network specific facilities information element (NSF IE) indicates which network facilities are being invoked. This information element is supported only for the 4ESS variant.
The following structure defines the NSF IE:
struct acu_ext_spf_fac_ie {
struct u4_acu_ext_hdr hdr; /* Extension header */
pad4
uchar net_id[ACU_MX_SZ_NET_ID]; /* Network identification array */
uchar net_id_lgth; /* Length of network identification*/
uchar net_id_type; /* Type of ID */
uchar action; /* Parameterized/binary indicator */
uchar serv_feature; /* Service/feature indicator */
uchar facility_coding; /* Facility coding */
uchar param_fld; /* Parameterized field */
pad5
};
Use the following macro to access the fields of the data structure:
Acu_ext_spf_fac_ie ( field )
