As described above, when the system processes each line of PABX data, it extracts the various components of a call record (eg. extension number, trunk, date components, duration components, etc.) using a lookup in the associated template file. For each type of call, the template file contains a line containing various characters which mark the position on each line of call data, where it should extract each element from.
The following characters are used to extract call record components from each line of PABX data:
| Character | Cell record element |
|---|---|
| a | Date: DAY |
| b | Date: MONTH |
| c | Date: YEAR |
| d | Time: HOUR |
| e | Time: MINUTE |
| f | Time: SECOND |
| g | Duration: HOURS |
| h | Duration: MINUTES |
| i | Duration: SECONDS |
| j | Extension Number |
| k | Trunk Access Code |
| l | Dialled Number / Dialled Digits |
| m | Trunk/Line Number |
| n | Response Time: MINUTES |
| o | Response Time: SECONDS |
| p | Account Code |
| q | Calling Line Identification (CLI) |
| r | History: Value (historic) |
| s | History: Pointer (historic) |
