摘要： PURPOSE: To secure a constant mark factor on a transmission line when the synchronism is fixed and to ensure a stable state of transmission, by cutting a loop until the frame synchronism is fixed at a center node and transmitting a fixed pattern at all times.
CONSTITUTION: The scramble state of an input signal 10 sent from a loop transmission line is released by a descrambler 4. A signal 11 is controlled by a frame aligner 5 so that the frame length is set at an integer multiple as much as the loop length. A frame synchronism detecting part 7 performs the front and back protections, and a changeover switch 9 is controlled according to the fixed state of the frame synchronism. The switch 9 is changed over at the side of a fixed pattern generator 8 when no frame synchronism is not fixed. A pattern 16 delivered from the generator 8 is scrambled and delivered in the form of a random pattern of a fixed mark factor.

摘要： PURPOSE: To detect missing of token quickly independently of the number of stations by using a function preventing circulation of a transmitted packet of a center station when a token is missing on a loop to lose a packet within two circulations in the loop.
CONSTITUTION: When the token is missing due to a faulty transmission line while only the token is circulated, the token, a start delimiter and an end delimiter do not exist on the loop and the missing of token is detected within a timer value TTNT. When the token is missing after a station transmits a packet and releases the token, the transmitted packet is lost in the transmission station after one circulation in the loop. Even if a packet sender address has an error, since the packet is lost by the function preventing the circulation of the same packet of a center station CS for two times or over, the packet does not exist on the loop within the two circulations in the loop after token missing and the missing of token is detected after a timer time TTNT.

摘要翻译：目的：通过使用防止循环中发送的分组的循环的循环中的令牌丢失循环中的两个循环中的分组丢失分组的功能来快速地检测到令牌的丢失，而不考虑站点的数量。构成：当只有令牌循环时由于传输线故障而导致令牌丢失时，循环中不存在令牌，起始分隔符和结束定界符，并且在定时器值TTNT内检测到令牌丢失。当站点发送分组并释放令牌之后丢失令牌时，在循环中的一个循环之后，传输的分组丢失在传输站中。即使分组发送方地址有错误，由于分组丢失了阻止中心站CS的相同分组两次或两次以上的功能，所以分组不存在于两个循环中的循环中令牌丢失后循环，并在定时器时间TTNT之后检测到令牌丢失。

摘要： PURPOSE: To apply retransmission of token at high speed by detecting a token from logical product between overflow signals of a counter counting a clock in an asynchronous data area up to the maximum packet length and a counter counting a loop circulating time.
CONSTITUTION: An end SD and a head of a packet in an asynchronous data area DASY inputted via a dynamic time division multiplex separation circuit are detected (26, 27) respectively, and an OR (29) signal is fed to a counter 30 to count a clock of the area DASY up to the maximum packet length l
pmax . On the other hand, an output of a token TK detection 28 in the area DASY is fed to a counter 31 and a transmission line clock is counted by a loop transmission line circulating delay time. Then two counters 30, 31 are provided and overflow signals of the two counters are ANDed (32) and a TK missing signal is fed to a TK generator 33. Thus, the generator 33 transmits a token TK into the area DASY.

摘要： PURPOSE: To improve the communication efficiency of a loop network by using a transmission line of the same direction as that used for inquiring the state of a destination node, obtaining acknowledgement from the destination node and using the transmission line in opposite direction when no acknowledgement is obtained and making communication similarly.
CONSTITUTION: A node 2 transmits a state inquiry instruction addressed to a node 4 by using a right-handed transmission line 101 in order to transmit a series of information DATA21, 22...24 by using the line 101. The node 4 receiving the instruction transmits acknowledgement information to the node 2. In this case, in order to confirm that the communication between nodes is made possible, the node 4 uses the right-handed transmission line 101 for acknowledgement. If a fault takes place in the line 101 and the node 2 cannot receive the acknowledgement, the node 2 regards the line 101 as the faulty line and transmits the information data to the node 4 newly via a left-handed transmission line 102, and the node 4 receiving it transmits the response via the left-handed transmission line 102.

摘要： PURPOSE:To obtain an optical branching coupler, by using a polarizing filter which divides light into two parts. CONSTITUTION:An optical fiber 21 is set at the left of a branching polarizing filter 29 and a coupling polarized filter 28 in parallel to the filter 29 at the other side of the filter 29. Furthermore, an optical fiber 23 is provided to form a coupling input optical path going toward the filter 28. Then optical fibers 22 an 24 pick up the reflected beams of both filter 28 and 29. In such constitution, the fibers 22 and 24 are not set on the same straight line and therefore the P wave delivered from the fiber 23 never enters the fiber 22. It is possible to obtain an optical branching coupler having such an effect even by use of a relfector 30.

摘要： PURPOSE:To achieve the orientation of failed position with a simple constitution, by constituting a timing extracting circuit with an elastic surface wave filter, oscillating this circut in frequencies inherent to the station itself at failure, and detecting this oscillatin frequency at monitor station. CONSTITUTION:When a failure is produced to a preceding relay device or transmission line and applied to an input terminal IN, the level of PCM signals is interrupted. The gain of an AGC circuit is maximum and the output of an equalizing amplifier EQ is noise only. A signal failure detector DET detects this state as failure and the output opens an AND gate G. When the gate G is opened, an elastic surface wave filter SAWFIL of a timing extracting circuit, a limiter LIMAMP, and a phase shift circuit PS operate as an oscillation circuit. This oscillation frequency is set to frequencies inherent to the station itself with the phase shift circuit PS and a monitor station can know the relay device or transmission line failed, by checking the frequency.

摘要： PURPOSE: To perform a shift to loop back and one-way loop conditions with high reliability in a loop network composed of two one-way circuits when a fault occurs in the transmission system.
CONSTITUTION: An input signal level detecting circuit and frame synchronism detecting circuit are provided in each node 1∼4 and, when these detecting circuits detect a fault in circuits, the signal of a normal loop is turned back while supplying signals to the loop, in which the fault is detected. When, for example, the clockwise loop between the nodes 2 and 3 is faulty, the turned- back signal from the node 3 is received at the node 4 and the synchronism of the clockwise loop is established. Then inputs of the clockwise loop are outputted to the clockwise loop and inputs of the counterclockwise loop are outputted to the counterclockwise loop. Thereafter, the synchronism between the node 4 and center node 1 is established in the same way and two transmission systems in which the sections between the remote node 4 and remote node 3 are set to turning-back modes are established.
