摘要： To prevent erroneous recognitions of line failures by a network apparatus, an alarm notifying controller region is provided independent from an actual data region in a connection between a line interface of the network apparatus and a terminal interface unit (line set). When a line is set within the network apparatus, an alarm notification path from the line interface to the line set is simultaneously set. When a line failure is detected by the line interface, information is notified the alarm notification path to all of the line sets connected to this line interface. In the line sets, a signal state of an interface is changed with respect to each sort of terminal interfaces, so that the line failure is notified to the terminal.

摘要： A communication system capable of high-quality routing and improved in operability. An IPsec tunneling control section sets up an IPsec tunnel on the Internet between the device in which it is provided and a remote router, by using an ISAKMP default route. A routing registration section has a routing table in which local IP addresses as destination addresses are statically registered and also a second router is statically registered as an IP default route for addresses other than the registered local IP addresses. When the IPsec tunnel is set up, the routing registration section identifies a global IP address of the remote router and dynamically registers the global IP address in the routing table in association with the corresponding local IP address. A packet transfer section transfers packets in accordance with the routing table.

摘要： A communication apparatus in a radio access network relays data transmission to and from a remote network. The communication apparatus includes a monitoring unit to monitor an authentication procedure performed when a mobile station makes a connection of a link to the remote network, as well as when the mobile station disconnects the link to the remote network. The communication apparatus also includes a producing unit to produce information for disconnecting a session of the mobile station based on progress of the authentication procedure monitored by the monitoring unit. For example, the producing unit produces information for disconnecting a session of the mobile station when the monitoring unit has observed deauthentication of the mobile station.

摘要： A method of communicating through a passive optical network (PON) that improves the efficiency of the network with low cost child apparatuses having only simple functions. A parent apparatus provides the child apparatuses with a multi-frame standard signal, and a child apparatus transfers asynchronous information as a frame of variable length, as it is, at a time delayed from the multi-frame standard signal by a time period designated by the parent apparatus. Since the asynchronous information does not need to be divided into pieces to which a frame header is attached, the efficiency of the uplink channel is increased.
