Operating parameters
This section lists the operating parameters for CIS ANI Digits Manipulation
and CIS Gateways Enhancements.

CIS ANI Digits Manipulation operating parameters

The data in ANI is built only once at the beginning of the call. The data is not
changed or re-downloaded for any kind of operation during a call. Therefore,
if the call goes through any type of modification such as a transfer or call
forward for instance, the ANI information sent when requested is of the
original originator of the call.
This feature does not allow the user to associate ANI entry to attendant
consoles. When an outgoing call is originated by an attendant, the ANI
message is built using the old mechanism.
The ANI size flexibility is not supported by the analog trunks (E3W, X3W).
For these type of trunks, the prompt ANSZ (LD 16) must be answered with
seven. CIS standards recommend setting ANSZ to seven for CIS DTI2
ANSZ prompt.

CIS Gateways Enhancements operating parameters

ANI is downloaded to the card only once and immediately after trunk
seizure. Thus calling number can be tandemed into ANI only if received
before trunk is seized. That means that the calling number must be received
at the same time that the called number or before enough digits of the
called number are received to seize the CIS trunk. In case of gateway ISDN
interface/CIS calling number (CLID) is always received before or at the
same time as the called number. In case of gateway R2MFC/CIS calling
number (CNI) can be received after trunk has been seized. Then incoming
MFC route must be configured to request CNI before enough digits of called
number are received to seize CIS trunk.
There is no cross checking of the ANI R_ENTRY associated with the route
against the ANI R_ENTRY in the customer Data Block. If an ANI R_ENTRY
is removed from the ANI table and the ANI R_ENTRY is stilled assigned to
a route, ANI in this case is built using the default R_ENTRY, R_ENTRY
number 0 and ERR9044 message is issued at call processing time.
