ANNOUNCE indicates announcements used
To cover each stage, three indexes are available in table MMCCSANN:
ADDR for address collection, CARD for card collection, and SUPP for
suppcode collection. Each index can then be datafilled to go to an
appropriate announcement Common Language Location Identifier (CLLI).
For example, CARD could be datafilled against an announcement CLLI that
gives the recording, "please enter your card number". If the indexes are not
allocated to an announcement CLLI or if the allocated announcement CLLI
is busy, a Storage Overflow Reorder (SORD) treatment is given.
Announcement CLLIs should be allocated so that there are enough CLLI
members datafilled to handle the highest traffic period. If the call attaches to
an announcement member that is already broadcasting to other calls, the
announcement is not heard until the beginning of the next announcement
cycle. The call will first try to attach to an idle announcement member. If
none are idle, the call will attach to an announcement member that is
broadcasting. To avoid large delays between announcement connect and
announcement playback, it is recommended that a large number of
announcement members be datafilled.
TONES indicates that tones are used.
The type of tone and duration for the card stage is programmable in table
OFCVAR through parameters MCCS_PROMPT_TONE and
MCCS_PROMPT_TONE_DUR, respectively. A delay before the tone is
given can be datafilled through parameter
MCCS_PROMPT_TONE_DELAY. This parameter is normally datafilled to
apply dial tone.
The universal tone Dial Tone is used for flexible card services during
address and suppcode stages of dialing.
Confirmation Tone
Field CONFTONE allows confirmation tone to be disabled on a per access
number basis. The confirmation tone that is given is datafilled in table
OFCVAR. It has a tone pattern of {on,off,on}. The timing of the pattern is
controlled by the following OFCVAR parameters:
MCCS_CONFIRM_FIRST_TONE_DUR,
MCCS_CONFIRM_OFF_TONE_DUR, and
MCCS_CONFIRM_SECOND_TONE_DUR. The tone that is given during
the "on" sequence of the pattern is determined by the OFCVAR parameter
MCCS_CONFIRM_TONE. Silence tone is given during the "off" state.
Variable Number of Card Digits
The fields MINDIGS and MAXDIGS in table FLEXSAC are present to
determine the number of card digits to collect. These fields should be
datafilled to include the pin digit count. For example, to collect a card
