BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention each comprises a two-stage link having a plurality of primary switch groups for accommodating and connecting subscriber lines and a plurality of secondary switch groups for connecting and accommodating lines to subscriber circuits of an exchange. An automatic connection of a subscriber line to a subscriber circuit of a corresponding service type of an exchange through an automatic MDF having a plurality of incomplete groups of networks and a crossover link connecting these networks to each other. The present invention relates to an automatic selection connection method in MDF.

2. Description of the Related Art Recently, in order to eliminate a connection restriction in each of a plurality of incomplete group networks composed of a two-stage link having a plurality of primary switch groups and a plurality of secondary switch groups, respectively, there has been a cross-link between networks. Provide a link to connect the subscriber line (incoming terminal) of any network,
Automatic MDFs have been developed with crossover links that allow them to be connected via the primary switches and crossover links of the network to the output terminals of the other network's secondary switches that provide the intended service.

In an automatic MDF having such a crossover link, even if an output terminal providing a desired service in an arbitrary network is in use, an output terminal providing a desired service in another network via the crossover link. Can be used, there is an advantage that the connection restriction in each network can be effectively eliminated, and the line connection efficiency can be greatly improved. On the other hand, however, there is a problem in that, when a path is connected, an output terminal that provides a target service of the network is connected to another network via a cross link and cannot be used, which often causes a link block.

Therefore, conventionally, a maintenance person connects an incoming terminal to an outgoing terminal having a desired service type so that the above link block does not occur.

[0005]

However, in order for the maintenance person to connect the input terminal to the output terminal having the intended service type while avoiding the occurrence of the link block, the maintenance person must have knowledge and know-how of the matrix configuration. However, there is a problem that fairly complicated operation technology is required, and there is a problem that work efficiency is poor.

The present invention has been made by paying attention to such conventional problems, and it is possible to effectively reduce the occurrence of link blocks and to improve work efficiency without requiring a complicated operation technique for maintenance personnel. Automatic MDF that can be improved
The purpose is to provide an automatic selection connection method in.

[0007]

In order to achieve the above object, according to the present invention, a plurality of primary switch groups for accommodating and connecting subscriber lines and a plurality of secondary switches for connecting and accommodating lines to subscriber circuits of an exchange. A subscriber circuit is subscribed to a service type corresponding to a switchboard through an automatic MDF having a plurality of imperfect group networks each configured by a two-stage link having a group and a crossover link connecting these networks. In automatically connecting to the subscriber's circuit, the control device of the automatic MDF monitors the connection state of the subscriber's line to the exchange, and the primary switch group of the subscriber's line to be connected to this control device from an external operation terminal. An input terminal and its service type are specified, and the specified input terminal is determined by the control device based on the specified information. Through the secondary switch group of the switch, it automatically searches for a free passage connected to the subscriber circuit of the service type corresponding to the exchange, and if there is a free passage in the network, the free passage The designated incoming terminal is automatically connected to the subscriber circuit of the service type corresponding to the exchange through the passage, and if there is no empty passage in the network, the connection link and the other network are connected. Via the next switch group, an empty passage connected to the subscriber circuit of the service type corresponding to the exchange is automatically searched, and the specified input terminal is made to correspond to the exchange through the searched empty passage. Automatically connect to the subscriber circuit of the service type.

In the present invention, the automatic M
When the incoming terminal of the primary switch group of the subscriber line to be connected and its service type are specified in the control device of the DF, the incoming state and its service type are changed from the connection state monitored by the control device. The path of the output terminal is automatically selected, and the subscriber line to be connected to the selected output terminal is automatically connected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of an example of the essential parts of an automatic MDF embodying the present invention. This automatic MDF1
Is a network 2-0 of a plurality of incomplete groups of two-stage links.
To 2-3, a crossover link 3 for connecting these networks to each other, and a control device 4 for controlling the connection in these networks 2-0 to 2-3 and the crossover link 3 and monitoring the connection state thereof. The control device 4 has a communication control device 5 for inputting information from the outside,
An input terminal of the primary switch group of the subscriber line to be connected and its service type are input to the control device 4 from the external operation terminal (for example, a personal computer) 6 via the public communication network 7 and the communication control device 5. Has become.

In this embodiment, the network 2-0
Each of 2-3 has a group of 10 primary switches each having an input terminal of 5 lines and a group of 5 secondary switches each having an output terminal of 6 lines.

The operation of this embodiment will be described below with reference to the flow chart shown in FIG. First, the operation terminal 6
In, the input terminal of the primary switch group of the subscriber line to be connected and its service type are designated, and the information is input to the control device 4 via the public communication network 7 and the communication control device 5. In the control device 4, the networks 2-0 to 2-3 are used.
And the connection state of the crossover link 3 is monitored, and first, based on the designated incoming terminal and its service type, in the network in which the incoming terminal is accommodated, the switch is dealt with via the primary switch and the secondary switch. It automatically searches whether or not there is a free passage to the output terminal connected to the subscriber circuit of the service type.

Here, if there is an empty passage in the network, the contacts of the primary switch and the secondary switch corresponding to the empty passage are controlled so that the designated input terminal is automatically set to the retrieved output terminal. , And the specified input terminal is connected to the subscriber circuit of the corresponding service type of the exchange.

On the other hand, if there is no empty passage in the network that accommodates the specified input terminal,
The control device 4 automatically searches for an empty path to the output terminal connected to the subscriber circuit of the service type corresponding to the exchange through the crossover link 3 and the secondary switch group of the other network, and searches for it. Correspondence of the exchange through the designated input terminal through the cross link 3 and the secondary switch of the other network by controlling the contacts of the primary switch, the cross link 3 and the secondary switch of the other network corresponding to the empty passage Automatically connect to the subscriber circuit of the service type
