• A PIC card blank should not be installed within a protect zone. It is not necessary to have a line card in
every slot of a protect zone.
• If another line card is configured as a Protect line card, then it forms a separate Protect Zone with the
successive working line cards below it.
• Every Protect line card must have an Protect PIC installed in the corresponding PIC slot in the rear of
the chassis.

DOCSIS MAC/PHY Cards
A DOCSIS MAC/PHY line card is paired with an RF Physical Interface Card (RF Through PIC or RF Protect
PIC).
RF Interface Line Cards
The Cisco cBR chassis supports the following RF Interface Line Cards:
• DOCSIS MAC/PHY SSI Card with two downstream D3.1 modules and one upstream D3.1 module
installed. [PID: CBR-LC-8D31-16U31]
• DOCSIS MAC/PHY SSI Card with one downstream D3.1 modules and one upstream D3.1 module
installed. [PID: CBR-LC-4D31-16U31]
• DOCSIS MAC/PHY SSI Card with two downstream D3.0 modules and one upstream D3.0 module
installed. [PID: CBR-LC-8D30-16U30]
