摘要:
In one configuration, the present invention is directed to an enterprise network that includes geographically dislocated first and second network regions 202 and 206 communicating with one another through first and second networks 252 and 248 and respectively comprising first and second gateways 220 and 224 and first and second groupings of trunks. A common electronic address is associated with the second grouping of trunks. A media server 200 is positioned in the first network region 202 that includes an inter-gateway routing agent 260. The first network region transmits, as part of the establishment of a real-time or near real-time communication between first and second subscribers respectively in the first and second network regions, the common address to the second gateway 224. After the outgoing communication is answered by the second gateway 224, the first network region transmits in band to the second gateway 224 a user identifier associated with the second subscriber and/or a phantom user. The user identifier is used to establish the communication with the second subscriber.

摘要:
In one configuration, the present invention is directed to an enterprise network that includes geographically dislocated first and second network regions communicating with one another through first and second networks and respectively comprising first and second gateways and first and second groupings of trunks. A media server is positioned in the first network region that includes a routing agent. When a WAN outage occurs, the routing agent, using a dial plan, maps the dialed digits to an electronic address addressable over the PSTN and routes the call over the PSTN to the destination second communication device in the second network region.

Apparatus and methods are provided for separately preheating gaseous ammonia and an oxygen-containing gas mixture, combusting them to form a hydrogen-containing gas mixture, and cooling the hydrogen-containing gas mixture in conjunction with the preheating of the next ammonia and the preheating of the next oxygen-containing gas mixture. Combustion may occur at combinations of pressure and temperature that permit rapid and non-catalyzed decomposition of the ammonia.

The present invention is directed to a secondary communication server 216 for assuming control of a communication formerly controlled by a primary communication server 212 in the event of a failure, comprising: (a) an input operable to (i) receive, from a first communication node 204a, first communication information, wherein the first communication information is associated with the communication and comprises a first node identifier 236a and/or a communication identifier 240a, the first node identifier 236a is associated with a second communication node 204b, the communication identifier is associated with the communication, and the second communication node 204b comprises second communication information associated with the communication and (ii) thereafter receive, from the second communication node 204b, the second communication information; and (b) a reconstruction agent 228 operable to identify the second communication information based on the first node identifier 236a and/or communication identifier 240a.
摘要:
Calling name presentation services are provided by maintaining a local cache of requested information. When a called destination is determined to subscribe to calling name presentation, the local cache is queried to determine if the calling number is in the local cache. If the calling number is in the local cache, information corresponding to the calling number is retrieved from the local cache. If the calling number is not in the local cache, a remote database is queried for the information. The information retrieved from the remote database is stored in the local cache. In either case, the name information is sent to the call destination. A Signaling System 7 architecture may be used to implement local caching.

A secured partitioned communication system includes a shared switch network system in communication with an Intelligent Network Processor (INP). A terminating Intelligent Communication Device (ICD) located outside the management and control of the network defines a boundary therebetween and permits multiple inter-dependant parts of the communication service to be distributed to increase functionality without modifying an existing network switch.

A method and system for conveying supervision information to a call processing system using an intelligent network is provided. A call originating at the call processing system is received by a network switch. The network switch sends a query to a service control point which returns a routing message to the network switch. The network switch routes the call and waits for supervision information corresponding to a request for subsequent information provided by the service control point. Upon receiving the supervision information at the network switch, the network switch informs the service control point of the supervision information. The service control point in turn notifies the call processing system of the supervision information. Advantageously, the interface need not have the ability to convey supervision information.

A pneumatically-powered battering ram for striking objects quickly and effectively with an initial high striking velocity resulting in an increased peak force effective in breaking the target object. The battering ram includes an elongated hollow housing containing a mass to be propelled, preferably a piston, and a supply of compressed gas, preferably carbon dioxide disposed within the housing. A valve mechanism releases a portion of the compressed gas into a charge cavity located between the piston and the supply of compressed gas. A sear mechanism holds the piston in place against the pressure of the compressed gas in the charge cavity. When the battering ram is swung at an object such as a door, a trigger mechanism releases the sear mechanism which in turn releases the piston. The piston is then accelerated forward by the compressed gas charge. Consequently, as the ram reaches the door, so does the piston which is traveling at a much higher velocity than could be obtained solely by manual swinging. As a result, the peak force initially imparted upon the door is greater and the door is broken down in a quick and efficient manner.

Described herein is an extravasation tester that pinches an infusion line closed between a wheel and a platen, and then peristaltically withdraws fluid into the infusion line as the wheel is rolled away from a puncture site. Extravasation is determined to have occurred if little or no blood appears in a sight chamber positioned near the puncture site when a test fluid is withdrawn into the infusion line from the puncture site.
