Creating a Direct Connect Connection

This topic describes how to establish a dedicated Direct Connect (DC) connection.

Before you begin

Complete the access point selection, onsite survey and other preparations. For procedure, see Preparations before access.

Procedure

Step 1: Create DC Connection

In the top menu bar, select a target region and project.

Click Create DC Connection.

Configure the DC Connection port based on the table below.

Parameter	Description	Sample value
Basic information
Access point mode	Select classic mode to create one access point in a single request.	Classic
Region	Select the access point region of the DC Connection.	China (Beijing)
Name	Enter a name for the DC Connection.	DAS123_port308_conn
Access point	Select an access point for the DC Connection.	Beijing-Chaoyang-A
Line operator	Select the type of Line Operator who constructs your DC connection.	China Mobile
Port speed	Select a port specification. Different specifications charge different port fees. Apply based on actual needs.	1G
Port type	Port Type supports the optical port. Port Spec determines the port rate. VolcanoEngine access point devices support single-mode optical ports with specifications of 1Gbps, 10Gbps, 40Gbps, and 100Gbps. tip Only Beijing-Langfang-C access point supports the 400Gbps optical port in DC connections with classic mode. If needed, please contact your account manager.	1G optical port
Affiliated project	The project to which the new DC connection belongs.	default
Billing rules	View and confirm the DC Connection billing rules.	Check

This example demonstrates only sample values for required parameters. For more parameter details, see Creating a Direct Connect Connection. Sample values are for reference only and have no practical significance.

After configuration, click Buy now to submit the application.

Step 2: Apply for LOA

LOA is a letter of authorization for the DC Connection construction in the VolcanoEngine access point data center. After the DC Connection application is approved, the status of DC Connection becomes LOA pending. Go to the VolcanoEngine DC Connection console to apply for the LOA.

In the top menu bar, select China (Beijing).

In the DC Connection list, click Apply for LOA to the right of the DC connection (DAS123_port308_conn), and configure the LOA application based on the table below.

Parameter	Description	Sample value
Company name	Enter the name of the company who uses the DC Connection.	ByteDance
Construction Company entering VolcanoEngine Data Center	Enter the name of the construction company	VolcanoEngine
Line type	Select a type for the DC Connection.	MSTP
Construction schedule	Select the expected construction schedule.	2023-06-30
IDC location	Enter the detailed address of the data center.	Room XX, XX Building, No. XX, XX Road, Chaoyang District, Beijing, China
Bandwidth	Enter the bandwidth of the DC Connection purchased from the Line Operator.	1,000 Mbps
Field Engineer	Enter names, contact information, and ID numbers of engineers for DC connection construction.	Wang , 1510086, Mainland China ID, 22222219990101**

Click Submit to complete the application submission and wait for LOA review.

Step 3: Construction by Line Operator

After the LOA application is approved, the DC Connection status becomes Line operator construction. Click Download LOA in the Actions column to the right of the target DC Connection to obtain the LOA for on-site construction.

You should take the LOA with you, and contact the Line Operator to construct the DC connection in the VolcanoEngine access point data center.

Step 4: Report completion

After the Line Operator completes the construction and you finalize the completion by testing the DC Connection link connectivity, you need to access the VolcanoEngine DC Connection console to report the completion.

In the top menu bar, select China (Beijing).

In the DC Connection list, click Completion report in the Actions column to the right of DAS123_port308_conn.

After confirming the information about the DC Connection to report, enter the Building Cable ID of the DC access point's data center.

Click Submit.

To this point, the status of DAS123_port308_conn changes to VolcanoEngine construction.

Step 5: Construction by VolcanoEngine

After the completion report is submitted, VolcanoEngine engineers will perform patch cord installation and check optical attenuation for your DC Connection. You will receive a notification via onsite message and SMS once the construction is complete. Wait patiently.

Step 6: Pay port occupancy fee

In the top menu bar, select China (Beijing).

In the DC Connection list, click Pay now in the Actions column to the right of DAS123_port308_conn.

Follow the guidance to complete the payment. After payment, the status of DAS123_port308_conn becomes Opened.
