450 CIS ANI Digits Manipulation and Gateways Enhancements
When the ANIC of the outgoing route is set to yes, data from the ANI table
entry configured for the incoming route is used, even if empty. Thus it is up
to the craftsman to ensure that the ANI built using the ANI table entry is
correct.
Mapping CNI to ANI, ANI to CNI On MFC routes, prompt ANDN is
currently defined. This prompt is removed and replaced by prompt ANIE
which allows configuring the ANI table entry number.
Both CNI and ANI contain a CAC field. The value and meaning of the field
in both cases are not the same.
On the gateway side of the R2MFC to CIS, the purpose of this mapping
is to convert the 10 MFC CAC meanings into CIS CAC meanings, or to
define a default CIS CAC value. For this, a conversion table is defined.
Conversion tables are defined in LD 15. Up to 32 tables can be configured.
A conversion table can be assigned on each MFC route. For this, the prompt
CAC_CONV is added to the MFC incoming route configuration. If no CAC
conversion table is configured on the MFC route, default table (number 0)
will apply to the MFC incoming route.
A CAC conversion entry contains the following data:
•CAC0 to CAC9: against CAC0 prompt is configured the CIS CAC value
to be sent if an R2MFC CAC of value 0 has been received.
•DFLT: against this prompt is configured the CIS CAC value to be sent if
the R2MFC CAC has not been received or is not in the correct range.
When CNI has not been received at the time ANI is built, a default value
must also be used. This default value is defined in the CAC Conversion
table. On CIS trunks, 10 CAC values can be sent, from 0 to 9. Each one
has a particular meaning (see "CAC conversion table entry 0 for R2MFC
route" (page 451)).
Default table is number zero and is configurable. After upgrade this table
is defined in memory as shown in table below. The craftsman must be
aware that modifying this default table after conversion will modify the CAC
generated for all gateway cases where the incoming route had a CAC set
to three (before upgrade).
In this default table all fields are set to three, as it is the current CIS CAC
default value. A value of three for CIS Category Code means the caller
is residential, business or hotel subset with the access to local network
and without access to automatic regional, toll, international network and to
chargeable service numbers.
