Both a connection server and a relay connection server are installed in an IP transfer network; a function similar to a line connection control of a subscriber exchanger is applied to a connection server; a function similar to a line connection control of a relay exchanger is applied to the relay connection server; and a terminal-to-terminal communication connection control method with using the IP transfer network is realized in such a manner that a telephone set and a terminal such as an IP terminal and a video terminal transmit/receive an initial address message, an address completion message, a call pass message, a response message, a release message and a release completion message, which can be made in a 1-to-1 correspondence relationship with line connection control messages of the common line signal system. Furthermore, while an address administration table is set to a network node apparatus of an IP transfer network, means for registering addresses of the terminals into this address administration table is employed, so that an IP packet communication by a multicast manner can be realized with improving information security performance.

This invention makes it possible to use a concave reflection mirror using metal in at least a concave reflective portion thereof for discharge lamps. The concave reflection mirror is characterized by including: a metallic concave reflective portion; and a neck portion for receiving therein a high voltage side seal portion of a high-pressure discharge lamp to be continuously applied with a d.c. voltage of 1000 V to 4000 V during an ignition phase, the neck portion protruding rearward from a central portion of the metallic concave reflective portion and being formed partially of an insulating member or entirely of an insulating material. The concave reflection mirror can have a concave reflective surface with improved curved surface precision thereby making it possible to reduce variations in brightness, use a multi-layered deposited film having a low heat resistance, and reduce the required cost considerably.

摘要:
To provide an integrated IP network containing therein a plurality of separated IP networks with a variety of characteristics, such as IP telephone network, IP video network, IP electronic text network, best effort network, IP data multicast network and IP-based TV broadcast network. In the integrated IP network there are virtually installed a plurality of IP networks with various features, such as IP telephone network, IP video network, IP electronic text network, best effort network, IP data multicast network and IP-based TV broadcast network. An address management table is set in each of the network node devices installed at input points through which the integrated IP network is accessed from outside. The address management table is registered beforehand with terminal addresses and port numbers identifying the application programs (AP) in the terminal. The address and port number written in the IP packet entered into the integrated IP network are compared with those registered in the address management table to route, inside the integrated IP network, the IP packet to an appropriate IP network. The port number may not be used and only the addresses may be compared.
摘要:
The intergrated information communication system is comprised of an access control apparatus for connecting a plurality of computer communication networks or information communication equipment to each, and a relay device for networking the aforementioned access control apparatus. The system has functions for performing routing by transferring information by a unified address system and by changing address at the access control apparatus, and is configured such that the aforementioned plurality of computer communication networks or information communication equipment can perform communications in an interactive manner. The integrated information communication system ensures communication speed, communication quality, communication trouble countermeasures in a unified manner, without using dedicated lines or the Internet, wherein security and reliability in communication is ensured without change of a private address system.
