    Abstract: An exemplary method and optical network that provide optical network restoration using refreshed state tables are disclosed. The exemplary method for recovering from a failure in an optical network using refreshed switch state tables includes generating and storing connection information in switch state tables of associated optical switches that define optical link connections to be made in the event of a failure, monitoring whether a failure has occurred, and refreshing the switch state tables by continuing to generate and store connection information in the plurality of switch state tables that are associated with the plurality of optical switches of the optical network until the failure in the optical network is detected. Once the failure is detected, optical switching is automatically performed in the optical switches based on the lookup table connection information in the switch state tables that are associated with the optical switches. The exemplary method may then include determining whether any of the telecommunications traffic in the optical links of the optical network was not restored due to the optical switching that was automatically performed.

    Abstract: An approach for providing content transmission upon placement of a call on hold is disclosed. A data communications system includes a proxy server that is configured to receive a message from a first client indicating the hold condition of a Voice Over Internet Protocol (VOIP) call with a second client. The system also includes a content server (e.g., music server) that is configured to transmit the content stored therein to the second client in response to a request message from the server.

    Abstract: An approach for providing charging information of a call established over a data network is disclosed. A communications system includes a user agent tha t initiates a call to another user agent according to an application layer protocol. The system also includes a network element that assists in establishing the call and forwards information indicating that the call is chargeable to the user agent. The present invention had particular applicability to SIP (Session Initiation Protocol) IP (Internet Protocol) telephony services.
