Features and Services
Operating parameters
The global NT5K48AA card supports the first stage dialtone detection of the
NT5K20AA and the NT5K20AB cards. Although the NT5K20AA and the
NT5K20AB can be used with the NT5K48AA, these UK cards do not support
second-stage dialtone detection because they cannot interpret the new Detect
Second Stage Dialtone message (second stage dialtone detection is not used
for the UK market).
Since there is only one parameter for the second stage dialtone detector (the
craftsperson, in LD 97, enters a value between 0-15 to indicate which of the
16 options to use), the parameters for second stage dialtone detection
hardware operation are hardcoded with limited flexibility. The NT5K48AA
has to be modified to provide second stage configuration, if it is to be
introduced to a country that has an undefined configuration.
The default values for all parameters are for the Swiss standards. However, if
the UK Program (UK) package 190 is equipped, the UK recommended
default values are used.
