- read this document and thoroughly understand the concepts and examples provided
- design the GWST process for the network before you attempt provisioning
- define the design criteria
- define the tables that are required for provisioning
- provision the table records in the appropriate order. Each table record must be provisioned separately.

The GWST screening process uses inter-related GWST tables in the following sequence (top-down):
- Incoming Linksets
- Incoming App IDs
- Allowed OPCs
- Blocked OPCs
- Allowed SIOs
- Allowed DPCs
- Blocked DPCs
- Affected (Allowed) Destinations
- Allowed ISUP Message Types

The gateway accounting supports the following two tables that are handled independently from the screening and redirection tables:
- Accounting MTP3 Rules
- Accounting SCCP Rules

Accounting record can be correlated to either an SS7 linkset or a user with an Application ID on a given NA. |

For example, if you are required to use the Incoming Linkset, Blocked OPC, and Allowed DPC screening tables, then the provisioning order would be
- Allowed DPC
- Blocked OPC
- Incoming Linkset
