In the figure, the solid arrow indicates the flow of the transmission path signal, and the broken arrow indicates the flow of the control signal. It should be noted that only the characteristic configuration of the present embodiment is shown in the figure, and other configurations are omitted.

The control unit 30 controls the program-controlled CP.
An interface setting control unit 31 which is realized by a memory such as U and RAM and controls settings of the interface units 101 to 10n is provided. The interface setting control unit 31
For a predetermined transmission line signal to be cross-connected, the interface units 101 to 10n of the receiving side that receive the transmission line signal and the interface units 101 to 10n of the transmission side that transmit the transmission line signal are set and transmitted. The setting of the interface units 101 to 10n is controlled by transmitting the connection IDs of the receiving interface units 101 to 10n to the side interface units 101 to 10n.

The interface units 101 to 10n include n reception transmission lines 401 to 40n and n transmission transmission lines 41
1 to 41n, and the cross-connect unit 30
Is connected to the connection part 31 of the. Also, connection ID management units 111 to 101 that receive and manage the connection IDs of the interface units 101 to 10 n of the reception sources that have received the transmission path signals transmitted by the own interface units 101 to 10 n from the interface setting control unit 31 of the control unit 30. 11n and connection ID insertion units 121 to 12n for transmitting connection IDs managed by the connection ID management units 111 to 11n to the cross-connect unit 20.
And

The connection ID insertion units 121 to 12n connect to the own interface unit 10 via the reception transmission lines 401 to 40n.
1 to 10n, and monitors the transmission path signal transmitted to the cross-connect unit 20.
The connection IDs managed by the n connection ID management units 111 to 11n are inserted. If there is no transmission path signal being received, a control signal including a connection ID managed by the connection ID management units 111 to 11n is generated and transmitted to the cross-connect unit 20.

The cross-connect unit 20 includes a connection unit 21 for connecting the n interface units 101 to 10n, a connection setting unit 22 for setting the connection of the connection unit 21, and a connection ID transmission / reception for the interface units 101 to 10n. Parts 121 to 12
and connection ID acquisition units 231 to 23n that receive the connection ID transmitted from the n.

The connection ID acquisition units 231 to 23n are provided in one-to-one correspondence with the interface units 101 to 10n. Then, the connection ID inserted in a predetermined time slot of the received transmission path signal or the connection ID included in the control signal is detected and extracted, and is sent to the connection setting unit 22. Thereby, any interface unit 10

The connection setting unit 22 includes a connection ID acquisition unit 231
Connection unit 2 according to the connection ID received from
1 connection is set. That is, the connection ID acquisition units 231 to 23n that have acquired the connection IDs recognize the interface units 101 to 10n on the transmission side of the transmission path signal, and
The interface units 101 to 10n on the receiving side of the transmission path signal can be recognized based on the content of D, and the connection of the connection unit 211 is set based on the recognition results.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG.

For a given transmission path signal, it is assumed that the receiving side is the interface unit 101 and the transmitting side is the interface unit 102. The connection ID of the interface unit 101 is “1”, and the connection ID of the interface unit 102 is “1”.
Is “2”.

The control unit 30 sends the connection ID management unit 11 of the interface unit 102 from the interface setting control unit 31.
2, the connection I of the receiving interface unit 101
D “1” is notified (step 201).

The connection ID management unit 112 receives the connection I
D “1” is managed as connection information, and the connection ID “1” is notified to the connection ID insertion unit 122 (step 202).

The connection ID insertion unit 122 is connected to the reception transmission line 40
Then, the connection ID “1” is inserted into an arbitrary free time slot of the transmission path signal received from the transmission path signal 2 and transmitted to the connection ID acquisition section 232 of the cross-connect section 20 (step 203). Here, it goes without saying that the transmission path signal received from the reception transmission path 402 is different from the transmission path signal for which a cross connection is currently being performed to set a transmission path. If there is no transmission path signal to be received from the reception transmission path 402, a unique signal with the connection ID “1” inserted is generated and sent to the connection ID acquisition unit 232 of the cross-connect unit 20.

The connection ID acquisition unit 2 of the cross connect unit 20
32 detects and extracts the connection ID “1” inserted in the transmission path signal received from the interface unit 102, and sends the extracted connection ID “1” to the connection setting unit 22 (Step 204).

The connection setting unit 22 receives the connection ID “1” from the connection ID acquisition 232, and
The interface unit 102 in which “1” is the connection ID “2”
It recognizes that it has received more. Therefore, the cross-connect setting is performed on the connection unit 21 so that the reception source ID is “1” and the connection destination ID is “2” (Step 205).

Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments.

[0034]

As described above, in the cross-connect device according to the present invention, when performing the cross-connect setting, the control unit notifies the transmission-side interface unit of the connection ID of the reception-side interface unit, and the cross-connection is performed. The connection setting and the management of the reception source in the transmission-side interface unit can be performed. This allows the control unit to perform only control on the interface unit.
There is no need to prepare, and only one type of control information needs to be managed, and there is an effect that the load on the control unit can be reduced.
