Table 18: Ports in the Interface Line Card
Description
Ports
The SSI Card has 8 downstream ports. These ports
support downstream DOCSIS and MPEG traffic on
the downstream PHY modules.
Downstream ports
The SSI Card has 16 upstream DOCSIS ports. These
ports support upstream DOCSIS traffic on the
upstream PHY module.
Upstream DOCSIS ports
The line card has the following LEDs:

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]
The Downstream D3.1 module has a green label on it.
Note
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.
