TIF Generic Routing Number Feature

The TIF Generic Routing Number (TIF GRN) feature allows for the insertion of a Generic Routing Number (GRN) digit string into the CdPN or CgPN of an outgoing IAM or Redirection Number of a REL ISUP message.

The GRN is obtained from the Number Portability lookup of the CdPN and CgPN digits.

TIF GRN provides Service Action Handlers for the GRNLKUP and CgPNGRNRqd Service Actions associated with TIF CdPN services TIF, TIF2, and TIF3 in NPP. The GRNLKUP Service Action allows retrieval of the GRN from the matched incoming CdPN to be inserted into the outgoing CdPN digits. The CgPNGRNRqd Service Action allows retrieval of GRN from the matched incoming CgPN to be inserted into the outgoing CdPN digits.

TIF GRN provides a Service Action Handler for the GRNLKUP Service Actions associated with TIF CgPN services TIFCGPN, TIFCGPN2, and TIFCGPN3 in NPP. The GRNLKUP Service Action allows retrieval of the GRN from the matched incoming CgPN to be inserted into the outgoing CgPN digits.

A TIF CgPN service is invoked by the corresponding TIF CdPN service by setting the INVKSERV parameter value to the TIF CgPN service name in the Service Rule for the TIF CdPN service.

The NPP GRN Formatting Action is used to process the GRN that is retrieved by TIF GRN Service Actions.

The NPP GRN Formatting Action is used for TIF GRN. The GRN Formatting Action is used to process the GRN that is retrieved by TIF GRN Service Actions.

The NPP GRN and GRNOTHER Formatting Actions are used for TIF GRN:

The GRN Formatting Action is used to process the GRN that is retrieved by TIF GRN Service Actions.
The GRNOTHER Formatting Action allows the GRN returned from a Number Portability search by the GRNLKUP Service Action for a TIF CgPN service to be used in CdPN formatting.

Basic TIF GRN Use Case for TIF CdPN Service

In the use case described in this section, the incoming IAM message contains CdPN=1238882223333 and CgPN=1239995556666.

The following Filter and Action Set components are used for the example:

Filter Prefix (FPFX) = 123
Filter Digit Length (FDL) = 13
Conditioning Actions = CC3 + AC3 + SN7
Service Action = CgPNGRNRqd
Formatting Actions = CC + GRN + AC + SN

The CgPNGRNRqd Service Action Handler performs an Number Portability DN lookup on the CgPN, finds the CgPN entry with GRN value a5d, and populates the GRN Formatting Action value with the GRN value.

NPP Formatting Action execution uses the extracted CdPN information and the GRN to construct the outgoing CdPN digit string as CC + GRN + AC + SN = 123a5d8882223333.

TIF inserts the outgoing CdPN digit into the outgoing IAM message. The CgPN is not changed. The IAM message is relayed.

Basic TIF GRN Use Case for TIF CgPN Service

In the use case described in this section, the incoming IAM message contains CdPN=1238882223333 and CgPN=1239995556666.

The following Filter and Action Set components are used for the example:

Filter Prefix (FPFX) = 123
Filter Digit Length (FDL) = 13
Conditioning Actions = CC3 + AC3 + SN7
Service Action = GRNLKUP
Formatting Actions = CC + GRN + AC + SN

The GRNLKUP Service Action Handler performs an Number Portability lookup for the DN in the CgPN, finds the CgPN entry with GRN value a5d, and populates the GRN Formatting Action value with the GRN value.

NPP Formatting Action execution uses the extracted information and the GRN to construct the outgoing CgPN digit string as CC + GRN + AC + DN = 123a5d9995556666.

TIF inserts the outgoing CgPN digit into the outgoing IAM message. The CdPN is not changed. The IAM message is relayed.

TIF GRN Use Case for TIF CgPN Service using GRNOTHER

In the use case described in this section, the incoming IAM message contains CdPN=4568882223333 and CgPN=1239995556666.

The following TIF Filter and Action Set components are used for the example:

Filter Prefix (FPFX) = 456
Filter Digit Length (FDL) = 13
INVKSERV=TIFCGPN
Conditioning Actions = CC3 + AC3 + SN7
Service Action = CDIAL
Formatting Actions = CC + GRNOTHER + AC + SN

The following TIFCGPN Filter and Action Set components are used for the example:

Filter Prefix (FPFX) = 123
Filter Digit Length (FDL) = 13
Conditioning Actions = CC3 + AC3 + SN7
Service Action = GRNLKUP
Formatting Actions = CC + AC + SN

The GRNLKUP Service Action Handler performs an Number Portability lookup for the DN in the CgPN, finds the CgPN entry with GRN value a5d, and populates the CgPN GRN Formatting Action value with the GRN value.

NPP Formatting Action execution uses the extracted information to construct the outgoing CgPN digit string as CC + AC + SN = 1239995556666.

TIF populates the CdPN GRNOTHER Formatting Action value from the CgPN GRN Formatting Action value.

NPP Formatting Action execution uses the extracted information and the CdPN GRNOTHER value to construct the outgoing CdPN digit string as CC + GRNOTHER + AC + SN = 456a5d8882223333.

TIF inserts the CdPN and CgPN in the outgoing IAM message. The outgoing message is relayed.
