Conveys additional called party address information to the far exchange in a subsequent address message.
typedef struct _subNum /* Subsequent Number */
{
ElmtHdr eh; /* element header */
TknU8 oddEven; /* odd or even */
TknU8 spare; /* spare bits */
TknStr addrSig; /* Address Signal */
} SiSubNum;
The fields in the SiSubNum structure are encoded as follows:
Field |
Value |
oddEven |
Specifies whether the number of digits in the addrSig field is even or odd. If even, the last octet contains two digits. If odd, the last octet contains only one digit and the most significant four bits not used. Defined values: 0 = NMB_EVEN 1 = NMB_ODD |
addrSig |
Actual address digits, encoded as shown in the following tables. |
For the addrSig field, the actual address digits are encoded as follows:
Octet 1 |
2nd address digit |
1st (most significant) address digit |
... |
... |
... |
Octet n |
m + 1th address digit or filler |
mth address digit |
where each digit is encoded with the following bit pattern:
