Serving Carrier & Reciprocal Switching Information

Serving Carrier & Reciprocal Switch Application

The Serving Carrier & Reciprocal Switch Application is designed to provide customers with information regarding the serving carrier(s) for a specific location, including the switch status:

  • Open (serving carrier provides switching for other carriers).
  • Closed and Local (serving carrier does not provide switching for other carriers and requires involvement in the line haul route).
  • Restricted (serving carrier ONLY provides switching under the identified conditions).

To help locate a customer facility, a partial name spelling, followed by an asterisk, can also be entered in the Customer Name or City fields.
