Cisco uBR10-LCP2-MC28C Overview
The Cisco uBR10-LCP2-MC28C cable interface line card supports Online Insertion and Removal
(OIR). OIR uses the MAC address assigned to the Cisco uBR10-LCP2, allowing you to replace a
Cisco uBR-MC28C on a Cisco uBR10-LCP2 adapter card without losing any configuration information.

Note
Do not attempt to separate or remove the Cisco uBR-MC28C cable interface line card from the
Cisco uBR10-LCP2 adapter card while it is inserted in the Cisco uBR10012 chassis. Remove the card
from the chassis as a unit and then separate them on a lab bench or other area that protects against ESD
damage.

Cisco uBR10-LCP2 Adapter Card and Cisco uBR-MC28C Cable Interface Line Card
The Cisco uBR10-LCP2-MC28C cable interface line cards, together with external IF-to-RF
upconverters, serve as the RF interface between the cable headend and DOCSIS-based cable modems
and set-top boxes (STBs). The cable interface line card supports 6-MHz National Television Systems
Committee (NTSC) channel operation, using standard (STD), Harmonic Related Carrier (HRC), or
Incremental Related Carrier (IRC) frequency plans conforming to EIA-S542. The card also supports
downstream channels in the 54 to 860 MHz range with upstream ranges of 5 to 42 MHz.
