The Text option allows you to select numeric (diagnostic) or verbal formats for
the ADMs presentation of network generated call progress and error code
information. These tables are used to translate between numeric codes and their
English text equivalents.
In the following tables, there are references to unknown numeric cause and
diagnostic codes in the form of xxx and nnn. Both xxx and nnn refer to one,
two, or three digit numeric values that may appear. At this time, no English
translation exists for these codes.
