Abstract: PURPOSE: To reduce the switching time of a server to be substantially zero and to structure an inexpensive system with high availability by allowing an inquiry means to inquire an address of a 2nd server if there is no response from a 1st server to a client's inquiry about an address. CONSTITUTION: The computers of a server 10 (server name: AAA) and a server 12 (server name: BBB) are placed in operation. Clients 1 and 20 inquire IP addresses of the server 10 as a primary name server according to a name server list 24. The clients 1 and 20 once receiving answers from the server 10 recognizes that a communication with the server AAA is established. For example, the server 10 becomes unable to provide service normally at a certain point of time. The name server part or the server 10 does not answer an IP address, so the client 20 switches the inquiry destination of an IP address to the server 12 as a secondary name server according to the name server list 24.

Abstract: The subject of the present invention are variants of ciliary neurotrophic factor with enhanced receptor selectivity (CNTFR), useful for the treatment of diseases and disorders including motor neuron diseases and muscle degenerative diseases. Another subject of the invention is to provide a method for identifying the above mentioned CNTF variants. The hCNTF variants with the amino acid substitutions in accordance with the present invention, have a reduced ability, as compared to the human CNTF, to elicit biological effects through soluble CNTFR, without affecting its ability to activate membrane-bound neuronal CNTF receptors, thereby improving its therapeutic properties. FIG. 1 shows the reduced CNTFR binding affinity of a CNTF variant according to the invention (IA-CNTF; SEQ ID NO: 2). It is evident that the binding affinity of this variant to the CNTFR is reduced as compared to the wild-type human CNTF molecule.

Abstract: PURPOSE: A method for testing a trunk line of a switch is provided to test the trunk line using resources of a switch system. CONSTITUTION: An MPM(Main Processor Module) searches whether a user requests the register of a trunk line testing telephone number through an APU and an IPM(400). If the user requests the register of the trunk line testing telephone number, the MPM receives the testing telephone number and transmission resource selecting information through the APU and the IPM and stores the received testing telephone number and transmission resource selecting information(404). The MPM searches whether an incoming call is generated(406). If the incoming call is generated, the MPM searches whether a telephone number of the generated incoming call is a telephone number previously registered as the testing telephone(408). If the telephone number of the generated incoming call is the telephone number previously registered as the testing telephone, the MPM transmits a response signal for setting calls to a transmission side and attempts a link connection(410). The MPM searches whether a link is connected(412). If the link is connected, the MPM searches whether the user selects an R2 frequency as a transmission resource(414). If the user selects the R2 frequency as the transmission resource, the MPM controls an R2 signal processing unit for transmitting the R2 frequency during a uniform time(416). If the user does not select the R2 frequency as the transmission resource, the MPM searches whether the user selects an announcement as the transmission resource(418). If the user selects the announcement as the transmission resource, the MPM controls an announcement processing unit for transmitting the announcement during a uniform time(420). If the user does not select the announcement as the transmission resource, the MPM searches whether the user selects the transmission of a hold tone as the transmission resource(422). If the user selects the transmission of the hold tone as the transmission resource, the MPM controls a clock and tone control unit for transmitting the hold tone during a uniform time(426).
