Whether universal line boards, TDM (SDH) boards, and packet boards can be used in a subrack in master-slave mode

Not all boards can be inserted to master/slave subracks. Project A in country I is used as an example. In the engineering design phase of this project, there are too many SLH14 fibers. To facilitate fiber maintenance, two SLH41 boards cannot be inserted into adjacent slots and SLH41 boards cannot be inserted in slots at the edge of a subrack. For services with heavy traffic, SLH41 boards can be installed in two subracks in master/slave mode. According to the feedback from field engineers, no SLH41 board can be queried on the NMS. There are restrictions on subracks for housing boards that support packet/SDH services.

SDH boards can be used only in an independent OSN 8800 subrack, but cannot be used in a subrack in master-slave mode.

When a universal line board carries packet services and SDH services, ODU Timeslot Configuration Mode can be set only to Assign random.

If the software version of TN11SCC is later than 5.35 in the master subrack of the OSN 6800, TN52SCC can be configured in a slave subrack. To ensure automatic software synchronization, ensure that the TN11SCC software package includes the TN52SCC software package.

No. Universal line boards can be used only in independent subracks, but not in the master or slave subracks.
