DCC Transmission Through External Clock Ports Solution

Using the DCC transmission through external clock ports solution, DCC bytes are placed in a specified E1 and then transmitted through a third-party network. In this solution, the transmission bandwidth of one E1 is used; therefore, this solution is applicable only when network management messages travel through a PDH network or a network that does not support transparent transmission of DCC bytes.

• Introduction
  This section defines the solution of transmitting DCC bytes through external clock ports and describes the purpose of using this solution.
• Configuration Procedure (DCC Transmission Through the External Clock Port Solution)
  To configure the solution of transparently transmitting DCCs through the external clock port, you need to perform other configuration operations in addition to configuring the HWECC solution.
• Configuring DCC Transparent Transmission Through External Clock Interfaces
  If a third-party network exists between networks composed of Huawei equipment, the external clock interfaces can be used to transparently transmit the DCC information. In this way, the U2000 Web LCT can uniformly manage the networks composed of Huawei equipment.
