Abstract: A transport adapter layer interface (TALI) includes messages, processes, and packet structures for sending and receiving SS7 information over a stream-oriented connection, such as a TCP/IP connection. For example, the TALI interface includes test messages for testing the status of a connection and allow and prohibit messages for enabling and disabling service data communications without invoking a TCP handshaking procedure. The TALI interface also includes SYNC and LENGTH fields for facilitating extraction of individual message packets over a stream-oriented connection.

Abstract: Methods, systems, and computer program products for accessing data associated with a plurality of similarly structured distributed databases are disclosed. According to one method, a first value of a data element associated with a first distributed database is received from the first distributed database. A second value of a data element associated with a second distributed database is received from the second distributed database. The first and second values of the data element are included in a third merged database. The first and second values of the data element in the third merged database are accessed.

Abstract: Methods and systems for transmitting user part messages between signaling system seven (SS7) signaling points over an internet protocol (IP) network include receiving, at a signal transfer point, a first SS7 user part message. The first SS7 user part message can be received from a first SS7 signaling point, such as a service switching point (SSP). The first SS7 signaling point is encapsulated in a first IP packet. The first IP packet is transmitted to a second SS7 signaling point over an IP network.

Abstract: A normalizing signaling gateway (NSG) routing node receives a first signaling message formatted according to a first variant of a common or standard signaling protocol, such as ISUP, and creates a second signaling message based on the first message. The second signaling message includes a normalized component and a variant component. The second signaling message may then be routed to a second NSG routing node or to a media gateway controller. Because the NSG routing node converts messages to and from variants of a standard signaling protocol, the media gateway controller is not required to support all of the variants of the standard signaling protocol, and its complexity is reduced.

Abstract: Methods and systems for ticket voucher flow control throttle MSUs that were enqueued during a signaling link failure. The throttling is performed based on a system of ticket voucher requests and grants. Communication modules seeking to send call signaling messages to outgoing signaling links issue ticket voucher requests. Grantors that are available to send the call signaling messages issue grants to the requestor. The grants may be based on the available capacity of an outbound signaling link.

Abstract: An end office support (EOS) routing node implements MTP layers 1-3 on behalf of one or more remote applications that share the true point code of the EOS routing node. Implementing MTP layers 1-3 includes receiving messages addressed to the true point code, determining whether the messages are contain application level information of interest to a remote application, and forwarding the application level information to the remote application. Messages may be routed internally within the EOS routing node using an internal point code used to uniquely identify the remote application within the EOS routing node. The EOS routing node may also perform network management functions on behalf of one or more remote applications.

Abstract: Disclosed is a communications network element that is capable of routing signaling messages and includes a dynamic routing key registration feature which allows Internet protocol (IP) nodes to automatically register/de-register and subsequently direct traffic towards or away from themselves without the need for manual operator intervention. A signaling gateway routing node includes a self-registering data communication module (sDCM) that is adapted to receive and process dynamic routing key registration messages from associated IP nodes. Such dynamic routing key registration messages may include information that is used to register a new routing key association with a TCP/IP connection, de-register an existing routing key association with the TCP/IP connection, or modify routing key information associated with the TCP/IP connection.

Abstract: According to one embodiment, a ventilation system includes a heat-recovery device for pre-heating make-up air with exhaust air from multiple drying chambers (e.g., dry kilns for drying lumber). The ventilation system includes ductwork connecting the drying chambers to the heat-recovery device in a parallel arrangement. Supply ductwork for supplying pre-heated make-up air from the heat-recovery device to the drying chambers includes a main supply duct, or conduit, in fluid communication with the heat-recovery device and plural branch supply conduits, each of which establishes fluid communication with the main supply conduit and a respective drying chamber. Return ductwork for delivering exhaust air from the drying chambers to the heat-recovery device includes a main exhaust duct, or conduit, in fluid communication with the heat-recovery device and plural branch exhaust conduits, each of which establishes fluid communication with the main exhaust conduit and a respective drying chamber.

Abstract: A methanol reforming catalyst containing passivated copper and zinc oxide and/or alumina can be prepared by (1) precipitating or spray-drying a mixture of catalyst precursor components dissolved or suspended in a diluent in order to form a solid catalyst precursor in the form of powder or granules, (2) calcining and reducing the solid catalyst precursor obtained in stage (1), (3) passivating the reduced catalyst precursor obtained in stage (2) and (4) shaping the passivated catalyst precursor obtained in stage (3) to form the catalyst. A reduction in the volume shrinkage and an increase in the mechanical hardness during operation of the methanol reforming catalyst are achieved by the preparation process.
