RTN 950 support 2.5G backplane capacity each slot at most. but configuration need to be done for 2.5G(defaulty 1Gbps). the backplane capacity is not only related to SCC board, but related to each kind of board.
1. Fot each board backplane capacity, please check in product document,for example EG4/EG4P(Description->IDU Hardware description->boards->EG4/EG4P->Functions and Feathers->Backplane bus bandwidth):
•1 Gbit/s when an EG4/EG4P board works with an SL91CSH board
•2.5 Gbit/s when an EG4/EG4P board works with an SL92CSH/CSHU/CSHUA board
2. If the board and SCC board support 2.5Gbps, you need to do configuration too
please read product document for detail: Reference->Network Management->Configuring the Backplane Bus Rate
Procedure:
1.In the NE Explorer, select the desired NE from the Object Tree and then choose Configuration > NE Properties from the Function Tree.
2.On the Advance Properties tab page, set the backplane bus rate in Backplane Bus Mode.
