Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm transfer system in a communication device.

[0002]

2. Description of the Related Art An alarm transfer system in a conventional communication device will be described with reference to FIG. An alarm transfer method in a conventional communication device includes an alarm information detection unit 3a that receives a communication line from outside the communication device and establishes synchronization and detects alarm information, an alarm information conversion unit 3b that converts detected alarm information, An alarm information output unit 3c for inserting a pattern and outputting alarm information processed in the communication device to a communication line, and a serial-to-parallel conversion of communication data and alarm information (hereinafter, "S /
P conversion ". ), Time-division multiplexing means 4b for time-division multiplexing communication data and alarm information of a plurality of communication lines, and outputting the converted alarm information to logically connected communication lines. For this purpose, a route setting means 4c for setting a route together with communication data, a separating means 4d for separating time-division multiplexed communication data and alarm information into respective communication lines, and a parallel-to-serial conversion of communication data and alarm information ( Hereinafter, this is referred to as “P / S conversion”.) P / S conversion means 4e and an algorithm setting means 4f for setting an algorithm for setting a table for alarm conversion, communication data and alarm information. It is configured.

Since the alarm transfer processing differs depending on the interface conditions, in this conventional system, the alarm information detecting means 3
The communication line synchronization is established and alarm information is detected at a, and the alarm information conversion means 3b performs alarm conversion processing. The alarm information conversion means 3b processes only the minimum necessary alarm information because alarm conversion is defined by the interface conditions of the communication line and the positioning of the communication device on the network. Since there is no such uncertain element, the alarm information conversion block 3b is entirely configured by hardware. The alarm information that has been subjected to the alarm conversion processing does not match the information amount of the communication data, and thus has a unique format. Since the route setting means 4c processes a plurality of communication lines in a time-division manner,
The communication data and alarm information obtained by the alarm information conversion means 3b are S / P converted by the S / P conversion means 4a, and the communication data and alarm information are time-division multiplexed by the time division multiplexing means 4b. In the route setting unit 4c, since the formats of the communication data and the alarm information are different, different algorithms are set by the algorithm setting unit 4f to set the route. The separation means 4d separates the communication data and the alarm information, and performs P / S conversion by the P / S conversion means 4e. Then, the alarm information output means 3c generates a synchronization pattern, and adds the alarm information to the communication line. Output.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. In this embodiment, a communication pattern is received from the outside of a communication device, synchronization is established, alarm information is detected, and an alarm information detection / internal interface conversion means 1a for converting the information into an internal interface is generated, and a synchronization pattern is generated. Alarm information output means 1b for outputting alarm information processed in the apparatus to a communication line, S / P conversion means 2a for converting communication data and alarm information from serial to parallel, communication data and alarm information for a plurality of communication lines Time-division multiplexing means 2b for time-division multiplexing, alarm information conversion means 2c for converting detected alarm information, and communication information for outputting the converted alarm information to a logically connected communication line. Route setting means 2d for setting a route; separating means 2e for separating time-division multiplexed communication data and alarm information into respective communication lines; Parallel → the P / S conversion unit 2f for serial conversion, and a, and the algorithm setting means 2g for setting an algorithm for route setting table and alarm information and communication data for alarm conversion.

The alarm information detection / internal interface conversion means 1a establishes communication line synchronization and detects alarm information, and assembles alarm detection information so as to conform to the format of communication data as shown in FIG. The S / P converter 2a S / P converts the communication data and alarm information obtained by the alarm information detection / internal interface converter 1a, and time-division multiplexes the communication data and alarm information by the time division multiplexer 2b. Become The alarm information conversion means 2c is constituted by a memory, and a table adapted to the corresponding alarm conversion specification is loaded in advance from the algorithm setting means 2g.
In the alarm information converting means 2c, alarm information of each time-division multiplexed line is given as an address of a memory as shown in FIG. 3, and data corresponding to the address is converted together with communication data as a result of converting the alarm information to the route setting means 2d. Output to

FIG. 4 shows an example of the structure of the alarm information.
In a communication line having such a structure, the alarm of the higher layer may not be transferred when the alarm of the lower layer is detected (this is called priority processing). Since the lower the layer, the more common the alarm is, the amount of information is smaller than that of the higher layer. According to the present invention, the alarm conversion processing is dynamically performed in a time division manner on a channel basis. When performing the alarm conversion processing based on the priority processing, the alarm information conversion means 2c uses the alarms of all layers as memory addresses at the time of performing one alarm conversion processing.
As shown in FIG. 5, the LINE alarm is copied to the timing of each channel, and the PATH alarm is copied to the timing of each corresponding channel, so that priority processing can be performed simultaneously in one alarm conversion processing time.

In the route setting means 2d, the communication data and the alarm information are obtained at the same time.
The route is set together by one algorithm set from g. The separating means 2e separates the communication data and the alarm information respectively and performs P / S conversion by the P / S converting means 2f.
The alarm information output means 1b generates a synchronization pattern, adds alarm information, and outputs it to the communication line.

[0012]

According to the alarm transfer system in the communication device of the present invention, the above-mentioned problem is solved, and the alarm conversion function is constituted by a memory and provided in the common part, and the alarm conversion processing of different interface conditions is performed in the firmware. The dependence eliminates the need for an alarm conversion processing circuit conventionally processed individually in the interface section of each communication line.
Also, in the future, when a communication device having a different position on the network is developed, it is possible to flexibly respond by changing only the firmware without changing the hardware. Another effect is that the route setting block 2d in FIG. 1 can easily encapsulate by setting the format of the communication data and the alarm information to be the same, and can cope with only one route setting algorithm. Is halved.
