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.
Figure 1 shows the Cisco uBR10-LCP2 adapter card with the Cisco uBR-MC28C cable interface line card installed.

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.
The two downstream ports and eight upstream ports support the modulations shown in
