Abstract: In a multimedia call center (MMCC) operating through an operating system, a client-specific self-help wizard is provided for active clients and updated periodically with information related to client transaction history with the MMCC. A connected client is presented by the wizard with a selective media function through which the client may a select a media type for interaction and help, and the MMCC will then re-contact the client through the selected media. The client, for example, may select IP or COST telephony, and the MMCC will place a call to the client to a number or IP address listed for the client, and interactivity will then be through an interactive voice response unit. Help information specific to a client is updated in the client's wizard periodically according to ongoing transaction history with the MMCC. The wizard may also monitor client activity with the wizard and make reports available to various persons.

Abstract: Methods and apparatuses for fault detection in a component associated with an application programming interface platform are provided. In an embodiment, the component is determined to have been invoked to process a transaction. A forward progress counter is monitored to determine whether the component is processing the transaction, wherein the forward progress counter increments at determined intervals when the component is processing the transaction. A test transaction is executed for the component when a determination is made that the forward progress counter has not incremented for a threshold fault period. A fault alarm indicator is generated based on the determination that the forward progress counter has not incremented for the threshold fault period.

Abstract: In an automatically switched optical network operating according to a wavelength plan, the wavelengths are assigned to an optical path based on availability, performance and SRS wavelength coupling reduction. First, the wavelengths are grouped in static bins based on their reach versus cost performance, and each bin assumes a ?Q of a middle wavelength. Then, the bins are moved into subsets of dynamic bins, constructed using bin constraints that account for the particulars of the respective optical path. The path is characterized taking into account the wavelength currently accessing at the end nodes, and the wavelength tandeming through the end nodes. Wavelength selection starts with the bins that satisfy the maximum number of constraints, and the wavelengths are checked sequentially against wavelength constraints; relaxed constraints are also applied when it is not possible to exactly satisfy one or more constraints.
