Extended error report
If the presentation is enabled (odd number), the TA returns an extended error re-
port every time it fails to establish a data or fax call. Errors are reported only for
failures that occur before call setup is complete, for example if the result code
NO CARRIER, NO DIALTONE or BUSY appears.

eral tables, sorted by different categories (see Chapters 8.1.6 to
