Cable Interface Line Cards
The Cisco uBR10-LCP2-MC28C cable interface line card is configured identically to the
Cisco
uBR-MC28C cable interface line card. For information about configuring the Cisco uBR-MC28C
cable interface line card, refer to chapter three of the Cisco uBR10012 Universal Broadband Router
Software Configuration Guide, available on Cisco.com or at the following URL:

Caution The Cisco uBR10012 supports only the Cisco uBR10-LCP2-MC28C cable interface line card bundle.
Do not install either the adapter card or Cisco uBR-MC28C card separately in the Cisco
uBR10012
chassis.
Figure 1-21 shows the Cisco uBR10-LCP2 adapter card with the Cisco uBR-MC28C card installed.

The cable interface card has two downstream ports and eight upstream ports. Each downstream port is
associated with four upstream ports in a DOCSIS domain. Each domain runs independently of the other.
The Cisco
uBR10-LCP2-MC28C cable interface line card uses a color-coded label to identify and group
the two downstream domains (DS0 and DS1). Their corresponding upstream ports are labeled U0
through U3.
