Abstract

To inform a location of a caller to the other party in an IP phone system, a wireless IC tag preserving unique ID information is attached to an optical connector of a user connection port. The relations between locations of the optical connectors and ID information of corresponding wireless IC tags are stored in a port control database. An IC tag reader in an optical network unit (ONU) reads the ID information in the wireless IC tag attached to the optical connector to which the ONU is connected. When an emergency call is initiated, the ONU transmits destination information of the emergency call and the ID information of the wireless IC tag to a central station. A control terminal in the central station compares the ID information of the wireless IC tag against the port control database to determine a location of the optical connector. The central station adds the determined location information to the destination information of the emergency call and transmits the information to an IP network.

Claims

1. An optical connector comprising an identification medium having identification information readable externally.

2. The optical connector of claim 1 wherein the optical connector comprises a frame and wherein the identification medium is embedded in the frame of the optical connector.

3. The optical connector of claim 1 wherein the identification medium comprises a wireless IC tag.

4. The optical connector of claim 1 wherein the optical user connector comprises a user connection port for connection to an optical network and wherein the optical connector is located at the user connection port for the optical network.
