Feature description 449
manipulated by assigning an ANI table entry to the incoming route. An ANI
table entry is also assigned to route types whose connectivity does not give
the possibility to receive a Calling Number. For these routes, the ANI table
entry allows to build the outgoing ANI using only information pertaining
to the incoming route.
CIS Gateway Enhancement introduces a list of ANI entries applicable to
incoming route considered for the gateway with CIS, or incoming and
outgoing route. When package CIST is equipped, an ANI entry is attached
to each applicable route. An entry for routes is configured with prompt:
R_ENTRY.
Some of the fields defined in ANI table entry were already existing in route
configuration. ANI table entry fields that were already existing on route
(RDNL, ANDN) are suppressed from the route. It must be noticed that
prompt RDNL of Route Data Block is replaced by prompt DNLG in ANI
table entry. A new prompt is added on Route data configuration to defined
ANI table entry: ANIE. During upgrades, former Route Data Block prompt
values are moved into an ANI table entry and this table entry is assigned
to the route.
Several routes can have the same tandeming information configured. The
data has been moved from Route Data Block to Customer Data Block. In
case no ANI table entry is configured, the default table entry (0) is used.
ANI is built as follows:
If outgoing route does not allow use of ANI table entry assigned on incoming
route (ANIC prompt of outgoing CIS route is set to NO), Calling number is
built as before. Notice that part of the received Calling Number (DNLG) and
ANDN INC route are configured in ANI table entry of the incoming route.
1. If outgoing route allows to use ANI table entry assigned on incoming
route (ANIC is set to yes on CIS outgoing route), ANI is built as LEC inc
route + ADDG inc route + (part of) received Calling Number or, when
calling Number not available.
With new implementation "part of received calling Number" indicates N
least significant digits of received Calling Number, where N is the value
configured against prompt DNLG in the ANI table entry associated to
the incoming Route Data Block.
2. LEC inc route + ADDG inc route + ANDN inc. route
ANI has a predetermined size, configured on outgoing CIS route. It can
happen that ANI built is smaller or longer than the ANI configured size. This
is handled the same way as for ANI built when call originator is a set.
