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.
| Step | Operation | Remarks | |
|---|---|---|---|
| 1 | Configuring the 16th E1 as the 2 Mbit/s External Clock Port |
Required for OptiX RTN 905. |
|
| 2 | Configuring DCC channels | Required. Set parameters as follows: NOTE:
For OptiX RTN 950/980, the external clock port on the system control, switching, and timing board in the slot with a smaller slot number corresponds to External Clock Source 1, and the external clock port on the system control, switching, and timing board in the slot with a larger slot number corresponds to External Clock Source 2. |
|
| 3 | Creating the Cross-Connections of Point-to-Point Services |
Required in indirect connection mode Perform this operation to set up the point-to-point cross-connection between the E1 port connected to the external clock port and the specific timeslot of the port on the SDH line board. This port on the SDH line board is used to interconnect with the third-party equipment. The specific timeslot is used to transparently transmit network management messages. NOTE:
For OptiX RTN 905, the point-to-point cross-connection between the 16th E1 to the specific timeslot on the SDH line port needs to be created. |
