Abstract:
The circuit includes a serial/parallel converting means (1) for controlling the incoming 400 Kbps serial data by means of a B channel clock (BCR) to output them in the form of a parallel data. A latching means (2) receives 8-bit parallel data from the serial/parallel converting means (1), and performs latching and reading on them in accordance with latch control signals and read control signals. A parallel/serial and speed converting means (3) converts the 8-bit parallel data of the latching means (2) to a serial data of 2048 Kbps in accordance with received signal load signals and 2048 Kbps bit clocks. An outputting means (4) outputs the data through 4 lines in the form of 2048 Kbps signals.

PURPOSE: An operation managing software process structure of a transmitting system is provided to transmit/receive a message rapidly although a plurality of messages are received by classifying a message according to functions in each receiving process module and receiving to the corresponding process. CONSTITUTION: A message process module(200) stores an alarm and a control status of a functional unit and analyzes a message received from a lower hierarchical operation managing unit and distributes and transmits the message to a system user graphic unit, a remote main operation managing process module, and a network managing system agent module. A message receiving module(210) from a user graphic interface receives a message from a system user interface and transmits the message to the corresponding module. A remote message transmitting module(220) transmits the received message to the remote main operation managing process module. A remote message receiving module(230) receives the message and decides whether the message will be transmitted to another place or a sub operation managing process module and transmits the message to the corresponding module. A message receiving module(240) from the lower hierarchical control unit receives the message and decides whether the message is a report transmitted to the network managing system agent module or the system user graphic unit and transmits the message to the corresponding module. A message transmitting module(250) to the lower hierarchical control unit transmits the received message to the lower hierarchical operation managing process unit. A message receiving module(260) from the network managing system agent transmits the message received from the network managing system agent to the corresponding lower hierarchical operating managing process unit. A message transmitting module(270) to the network managing system agent transmits the received message to the network managing agent. A message transmitting module(280) to the user graphic interface transmits the received message to the user graphic interface.

PURPOSE: A method for forming ring map data and a method for generating the information related to the isolation and separation of a ring are provided to establish the data of a ring phase, by adopting a duplicate connection list structure in order to easily check the isolation and separation isolation and separation thereof in a two-line ring network. CONSTITUTION: It is checked if the unique number of a from-node equals to that of a to-node(201). If the two numbers equal to each other, the unique number of the to-node is inserted into a list(SqNodeList)(202). If the two numbers do not equal to each other, the unique number of the from-node is stored in a variable(i)(203). The data stored in the variable(i) is compared with the unique number of the to-node(204). If the data does not equal to the unique number of the to-node, the variable(i) is inserted into the list(SqNodeList)(205). If the node is a west node(206), a node in a west direction of the variable(i) is updated(207). If the node an east node, a node in an east direction of the variable(i) is updated(208). If the data equals to the unique number of the to-node, the variable(i) is inserted into the list(SqNodeList)(209).

Abstract:
PURPOSE: A method for interworking an upload/down between control boards is provided to increase a reliability of a synchronous circuit distribution device by interworking a precedence control board and a subordinate control board. CONSTITUTION: On the occasion of a mounting and a detachment of a central concentrating control board(2), the central concentrating control board(2) requires present state information of subordinate control boards(3) in the time of the mounting(13). The subordinate control boards(3) reports the present state information of subordinate control boards(3,14). The central concentrating control board(2) transmits device information to each of the subordinate control boards(3,16). On the occasion of re-connection of the central concentrating control board(2) and a user interface(1), the user interface requires the present state information of the central concentrating control board(2,18). The central concentrating control board(2) reports the present state information(19). The user interface transmits the device information(21). On the occasion of a mounting and a detachment of the subordinate control board(3), the subordinate control board(3) performs an initialized routine. When there is no response of the central concentrating control board(2) pertinent to the initialized routine, the subordinate control board(3) operates in an independent operation mode. On the contrary, when there is the response of the central concentrating control board(2) pertinent to the initialized routine, the subordinate control board(3) operates in an interworking mode. After finishing an initialization, the subordinate control board(3) transmits an initialization finish message to the central concentrating control board(2,12). After this, the subordinate control board(3) transmits the present state information to the central concentrating control board(2,14). Next, the central concentrating control board(2) transmits download information to the subordinate control board(3,16), and the subordinate control board(3) performs a construction and a control of related boards.
Abstract:
PURPOSE: A method for processing bilateral remote registration in a synchronous transmission network is provided to supply service of the remote registration between synchronous transmission units in the network. CONSTITUTION: When a remote registration is received, it is checked from which station this message is received(401,402). If the message is sent from a remote base station, the length of the message is checked(403), and it is determined whether an address and a connection number of the message have been registered in a list(404). According to a remote registration state, a service standby procedure and a service use procedure are performed(405-407). If the address and the connection number thereof are not included in a remotely registered list, a service suspension procedure is performed(409). If the received message is related to its base station, it is checked whether the address and the connection number thereof are included in a list for offering the remote registration service(411). If remote registration is not possible, the service standby procedure is performed(416), and otherwise the service use procedure is carried out(417).
