The fields in the SiGenAddr structure are encoded as follows:
Field |
Value |
typeOfAddr |
Type of address. Defined values: 0x00 = DIALNUM 0x01 = DESTNUM 0x02 = SUPADDR_FAIL 0x03 = SUPADDR_NOTSCREEN 0x04 = COMPLNUM |
natAddr |
Nature of address indicator. Defined values for all variants: 0x01 = SUBSNUM Subscriber number 0x03 = NATNUM Nationally significant number 0x04 = INTNATNUM International number Additional values for ANSI: 0x71 = SUBSNUMOPREQ Subscriber number operator requested 0x72 = NATNUMOPREQ National number operator requested 0x73 = INTNATNUMOPREQ International number operator requested 0x74 = NONUMPRESOPREQ No number present operator requested 0x75 = NONUMPRESCUTTHRU No number present cut-through call to carrier 0x76 = NINEFIVEOH 950+ service 0x77 = TSTLINETSTCODE Test line test code |
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 |
Reserved |
Reserved bits. |
presRest |
Presentation restriction. Defined values: 0x00 = PRESALLOW Presentation allowed 0x01 = PRESREST Presentation restricted 0x02 = ADDRNOAVAIL Address not available |
numPlan1 |
Numbering plan. Defined values for all supported variants except BICC: 0x00 = NP_UNK Unknown 0x01 = NP_ISDN ISDN/telephony according to E.164/E.163 0x02 = NP_TEL Telephony numbering according to E.163 0x03 = NP_DATA Data numbering according to X.121 0x04 = NP_TELEX Telex number according to F.69 0x08 = NP_NATIONAL National standard numbering 0x09 = NP_PRIVATE Private numbering plan 0x0f = NP_EXT Reserved for extension |
Spare |
Spare bits. |
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:
