Intra-station control system for connectionless communications system

When setting up a working path, a protection path is automatically set up by taking each node on the working path as a start point. A working path setup request message carrying 'protection needed/not-needed' information is transmitted from an ingress node toward an egress node along the route of the working path. When transferring a path setup response message as a response to it, each node autonomously determines the route of the protection path and sends out a protection path setup request message along the route of the protection path.

Method and apparatus for protection path setup

The quality and performance of the connectionless communications system are improved. When a BOM is received, the destination address DA of the L3-PDU stored in the payload of the BOM is retrieved, and the tag information is obtained from the DA (S,). The output message identifier MID is reserved (S,), and the tag information and output MID are assigned to the BOM (S,). Then, the tag information and output MID are written to the table. When a COM is received, the tag information and output MID are retrieved using the MID of the COM as a key, and the information is provided for the COM (S,and S,). When an EOM is received, the tag information and output MID are retrieved using the MID of the EOM as a key, and the information is provided for the EOM (S,and S,). Then, the output MID is released (S,).

Connectionless communications system, its test method, and intra-station control system

For both a bandwidth-guaranteed connection call and a non-bandwidth-guaranteed connection call together, with respect to the bandwidth-guaranteed connection call, a schedular allocates the number of time slots which correspond to a required bandwidth to the bandwidth-guaranteed connection call from among the N time slots that constitute one period and so controls as to transmit an ATM cell at an allocated time slot. The non-bandwidth-guaranteed call transmitting unit transmits an ATM cell of a non-bandwidth-guaranteed connection call at a time slot which is not allocated to any bandwidth-guaranteed connection call. A congestion/normal state monitoring unit sets in advance a queue length which is regarded as the occurrence of a long-term congestion in a queuing buffer and compares the actual queue length with the preset queue length so as to detect the occurrence of a long-term congestion.

ATM exchange for monitoring congestion and allocating and transmitting

A media information distribution service system, such as a video-on-demand service system, is disclosed which, even if the capacity of a line is small and the number of lines connected to a media server, such as a video server, has to be increased accordingly, permits an uneconomical increase in the number of line circuits in the media server to be checked. In the system, a subscriber group that a distributor accommodates can be associated with a plurality of distributor-side paths on a distributor-side line. Each of the distributor-side paths is connected to a respective one of server-side paths on separate server-side lines connecting the media server and an exchange. In sending media information to a subscriber group, an in-server path control unit installed in the media server is permitted to select a free one out of server-side paths on server-side lines allocated for that subscriber group and activates a line interface corresponding to the free server-side path.

Media information distribution services system and method

A CPU sets one of first and second memories as an 'active system memory' and the other as a 'standby system memory'. Data about a combination of the VPI/VCI and TAG data is registered in and deleted from only the memory set as the 'active system memory'. The CPU, only when a null entry exists in a position satisfying a VPI/VCI increasing sequence with an increased address value, registers this null entry in the active system memory with data about new combination of the VPI/VCI and the TAG data. Whereas if there is no such null entry, the CPU reads the data about all the combinations of the VPI/VCI and the TAG data which are registered in the active system memory, re-sorts the read data and the data about the new combinations in the VPI/VCI increasing sequence and write the data from the head address in the standby system memory in a sorting sequence. The CPU, when finishing this writing process, resets the memory so far working as the standby system to an active system memory and the memory so far working as the active system to a standby system memory.

ATM node and routing data registering apparatus

A subscriber line control device utilizes a scan input table and a last look table. The scan input table stores respective current line states of a plurality of analog subscriber lines. The last look table stores respective preceding line states of the plurality of analog subscriber lines and information for validating or invalidating a timer device. A valid timer device corresponds to when a monitoring process is required. The scan input table is compared with the last look table at every predetermined cycle. When they do not match, it is judged whether the line state has changed or if the timer device is validated. Based on the judging result, an analog subscriber line control is performed according to an instruction specified by a call processing unit. The analog subscriber control is any of a call origination monitor, a dial pulse monitor, and an on-hook and off-hook (HIT) monitor.

Subscriber line control apparatus to concurrently detect change in line

A data transfer system including an exchange, wherein the exchange transfers data by sharing a plurality of channels by a time division multiplex mode. In this case, the exchange transfers the data by variably allocating respective time slots to be occupied by the respective channels. That is, it is possible to allot any line speed to any channel and therefore possible to mix signals with different data transfer speeds in the frames. This results in an exchange network with a high degree of freedom of transfer for the subscriber terminal equipment.
