Abstract: When a station is connected via a connector to an AC adapter, a controller may detect the event of connection between the station and the adapter and drive a suppression signal transmitter to send a suppression signal to suppress a handover by the station. The station may include a communication controller to fix, upon receipt of the suppression signal from the adapter, a wireless access point to which the station belongs. The station may enter a handover suppressed state in which the station does not conduct a handover to belong to another wireless access point so long as the station is connected to the adapter and is receiving the suppression signal. This may suppress the excessive handover and secure stable communication quality.

Abstract: An ISDN response system comprises a plurality of terminals, each of which contains a SETUP message to an incoming all. Each terminal has the same subscriber number with the same attribute values and responds to a first SETUP message received by it which has the aforementioned subscriber number and attribute values to transmit a CONN message to the termination so that communication is established between the network and the particular terminal, the CONN message of which is first received at the termination. The timing of the transmission of the CONN message sent by the particular terminal is delayed when a subsequent SETUP message is received having the same subscriber number and attribute values.

Abstract: The invention relates to method and apparatus by which the order in which ISDN terminals answer incoming calls can be easily established and changed by the ISDN user. The order is established by assigning a waiting time to each terminal, this waiting time being determined, e.g., by the subscriber number of an incoming caller or the type of call. A terminal only signals its eligibility to accept an incoming call after the waiting time has elapsed and its compatibility with the call has been established.

Abstract: A simple adapter for multiplexing ISDN (Integrated Services Digital Network) terminals adapter for an ISDN basic subscriber access system is connected by a connector to a subscriber's point-to-multipoint bus. The adapter allows a greater number of terminal equipment (TE) to be connected to the point-to-multipoint bus via S/T interfaces. By checking the type, subaddress or the like of a call coming in through the adapter, the adapter is capable of limiting the kind of acceptable calls.

Abstract: A time switch with a dual structure-type control memory utilizing a time division time switch. The switch is equipped with a speech memory unit into which digital signals to be interchanged are temporarily written, and a control memory unit into which addresses to be accessed by the speech memory unit are written. The control memory unit has first and second memories. Each memory has an input/output section connected to a memory controller. The memories are set during hard and soft cycles so that when either one of the memories is set in a hard cycle the other memory is set in a soft cycle. The hard cycle is a speech-control data read-only mode. The soft cycle is a speech-control data read-write mode under control from the memory controller.
