Downstream PHY Module
Each interface line card supports two downstream PHY modules. The Cisco cBR chassis supports the following
downstream PHY module versions:
• Downstream D3.0 (supporting DOCSIS 3.0). [PID: CBR-D30-DS-MOD]
• Downstream D3.1 (supporting DOCSIS 3.1). [PID: CBR-D31-DS-MOD]
Note
The Downstream D3.1 module has a green label on it.
The following limitations are applicable to the downstream PHY modules:
• All interface line cards in the chassis must have the same downstream PHY module version; that is all
D3.0 or D3.1 modules.
• In an interface line card, both the downstream PHY modules must be the same version; that is both D3.0
or both D3.1 modules.
