FID RULES/CONSTRAINTS:

1. Approved for use for Access Service Tariff application only.

SERVICE ORDER ACTIVITY NOTES:

1. SCRT and data provide the capability of screening and rerouting originating traffic from an end office to a trunk group to a customer designated premises, based on line class of service, service prefix indicator or service access code.
2. The associated trunk group may be equal to the Two-Six Code (TSC) indicated on the order, therefore, the two or six code information behind the SCRT FID is redundant and is not always reflected.
