Special Number. The call-type before digit manipulation is determined as
follows:
• If the call-type before digit manipulation is SPN (Special Number), it is
converted to a value corresponding to the CLTP parameter in the Special
Number Translations data block, as shown in Table 16.
• If the call-type before digit manipulation is not SPN (Special Number),
it is not changed.
CLID verification
Use the CLIDVER prompt in LD 20 (for Release 4.0 and Release 4.5) to
verify that the CLID has been properly composed and configured. This
command simulates a call, without actually making the call, and generates a
report of the properties of the call.
