Chapter 4, Description of Fields

Fields

Encoding

This field determines how the characters in the User Data field will be encoded in the SMS message. The choices currently available are:

Octet causes each character to be encoded as a byte (8-bits).

7-bit ASCII causes each character to be encoded in 7-bit lengths.

Shift-JISallows Kanji and Kana characters to be sent. Arib T53 must be selected in the Protocol field before this choice is available.

GPIB Example

“CDMA:SMS:ENC ‘Octet’“

selects the “Octet” format.

Operating Considerations

If you select Octet and the Data Mode field is set to Hex, the Test Set will put each byte of data from the User Data field in the SMS message without translation.

If you select 7-bit ASCII and the Data Mode field is set to Hex, the Test Set will truncate the most significant bit of each byte of data from the User Data field, then put the resulting 7-bit data in the SMS message without translation.

If the Data Mode field set to ASCII, the Test Set will translate the data from the User Data field using the ASCII code chart, then put the resulting data in the SMS message in 7-bit or byte format depending on the selection you make in this field.

The data from characters entered in the User Data field are put in the CHARi fields of the User Data subparameter of the SMS message as described in Section

4.5.2of IS-637 and TSB79. This field affects this subparameter as shown in table

12.
