Note: Address digit collection is handled in the same manner as the
domestic address digit collection for MWC card calls. The only difference
is MWC card calls must collect a minimum of 4 digits while the flexible
card calls must collect a minimum of only 2 digits and a maximum of 15
digits.
Flexible Dialing Stage
Normal Digit Collection Using BEGSTAGE
Field BEGSTAGE allows the choice of stage to begin digit collection.
ADDRESS denotes collect address followed by card digits and CARD
denotes collect CARD followed by ADDRESS digits.
Treatments that cause Address and Card Digits to be recollected
beginning with the stage indicated by field BEGSTAGE
Treatments VACANT_CODE (VACT), VACANT_COUNTRY_CODE
(VCCT), and NCS_INCOMING_EXCLUSION (NCIX) cause a restart of
digit collection beginning with the BEGSTAGE value.
Note: Only one chance is given to enter the digits again after treatment.
Treatments that cause Card Digits to be recollected
Treatments CALLING_CARD_TIMEOUT (CCTO) and
CALLING_CARD_INVALID (CCNV) cause a recollection of card digits.
In some cases it may be necessary to collect Address Digits also. If the
value of BEGSTAGE is equal to ADDRESS, it is only necessary to recollect
card digits since Address Digits have already been collected. However, if
the BEGSTAGE is equal to CARD and the card failure occurs before a NCS
request, the Address Digits have never been collected.
If BEGSTAGE is equal to CARD, it is impossible to get the
CALLING_CARD_TIMEOUT treatment and go to the CCTO
announcement. In this case, a time out must be treated as if it were a rotary
card time out to the operator.
Selectable Prompts
During card processing, there are three stages of digit collection: address,
card, and suppcode. Each stage must prompt the user to enter the
appropriate digits for the current stage. Field PROMPTS allows the user to
fill the field with either announcements or tones.
Note: Currently, the suppcode stage is only supported on flexible card calls
that have CARDTYPE of FLEXCARD and when a Card Service Response
with a non-zero Supplementary Code Length is returned from the DAP.
