5. RECORD LAYOUT

5.1. SINGLE-SITE CALLS

The following diagram shows the layout of the fields in a basic CDR for a single-site call. The top row shows the field name and number, the middle row shows the subfield name and letter, if applicable, and the bottom row shows the byte offset within the record.

5.2. MULTIPLE-SITE CALLS

A CDR may have 0 to n additional fields added beginning at byte offset 70, where n = No. of Sites - 1. The format of the additional fields is identical to the Site of Origin field (field 13) and is shown in the diagram below. The offset, x, of the first byte in each additional field is calculated as x = 62 + (8n).

5.3. MOBILE-TO-LAND TELEPHONE INTERCONNECT CALLS

A CDR for a mobile-to-land telephone interconnect call will have an additional field beginning at byte offset 70. This field contains the digits dialed by the caller. A mobile-to-land call never involves multiple sites, so the PSTN Telephone Number field is never combined with the Additional Site fields described in the preceding section.
