OSI Over DCC Solution

Basic Concepts of OSI over DCC
This section introduces the basic concept of OSI over DCC.
Application of OSI over DCC
According to different network situations, OSI over DCC has two major applications.
Configuration Process
The configuration of the OSI over DCC solution must comply with the process.
Modifying the NE ID
In the commissioning or expansion process, when you need to adjust the original planning and change the NE ID, you can use the Web LCT to achieve it.
Setting the NSAP Address for an NE
You can use this procedure to set the NSAP address for an NE and change the NSAP address of an NE if needed.
Configuring the Node Type for an NE
Based on the network planning, you can set the node type to ES, L1-IS or L2-IS for an NE. For easy expansion of the network, avoid the ES type.
Configuring the Communication Protocol Stack and LAPD Role for an Optical Port
The default protocol stack enabled for optical ports on an NE depends on products. If the current protocol stack enabled for an optical port differs from the planned one, you can configure it on the Web LCT. If an optical port uses the OSI protocol stack, the link access procedure on the D channel (LAPD) role of all optical ports is User by default. You can set the LAPD role for each optical port based on network planning. The local LAPD role depends on the remote LAPD role. Ensure that the two LAPD roles are different.
Configuring OSI Tunnel
When the OSI-protocol-based third-party equipment needs to transfer information through an IP network that consists of Huawei equipment, you can create a virtual OSI tunnel to transparently transmit the information.
Customizing Communication Channels Between NEs
NEs communicate with each other through data communication channel (DCC). To meet the requirements of the network management in a complex network, you can configure D1-D3, D4-D12, D1-D12 as DCC and multirate DCC. When configuring the DCC, you need to set the DCC rate and allocate DCC resources according to DCC channel types.
Querying the Route Information of a Node
After you finish configuring and connecting the fibers, you can check whether the route information of each node is correct. If the route information is correct, it means that the nodes can normally communicate with each other.
Creating an OSI GNE
After you configure the NSAP address of an NE, you can create an OSI GNE in the TP4 connection mode.
Application Example for Hybrid Networking Based on OSI over DCC
This section takes an example to describe the method of configuring the OSI over DCC solution.
