1.3 TIF Configuration Options
The following types of configuration options are used with TIF features:
-
TIF configuration option values in the TIFOPTS table influence number conditioning, response message formatting and generation, and Service Portability processing.
-
Remote SP based options can be used with or instead of the TIFOPTS configuration options for outgoing message formatting.
TIFOPTS Configuration Options
The options described in the following table are used for the following functions:
- Specify the conditioning that is needed before CdPN or CgPN lookup.
- Specify the conditions that indicate a successful Number Portability lookup.
- Specify Service Portability processing that can be performed for IAM messages.
- Specify the cause for a Release message.
- Indicate when to split the IAM message into an IAM message and a SAM message.
- Specify the digits to substitute for the Calling Party Number in Simple Number Substitution.
- Indicate the Calling Party's Category value for the Public DN for the network in Number Substitution.
-
Specify the format and contents of fields in the outgoing message (CgPN digits, NM bits, delimiter digits, Area Code, Release Cause, Default RN).
