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.

The Cisco uBR10-LCP2 adapter card has its own set of status LEDs on top of the front panel. Table 2 on page 6 describes the LCP2 card LEDs and their function.
