The Cisco uBR10-LCP2-MC16xcable interface line cards together with external IF-to-RF upconverters, serve as the RF interface between the cable headend and DOCSIS/EuroDOCSIS-based cable modems.
The Cisco uBR10-LCP2-MC16xcable interface line cards are a combination of two components:
•Cisco uBR-MC16xcable interface line cards—Provide one downstream and six upstreams channels.
–Cisco uBR-MC16C and Cisco uBR-MC16S support cable modems and set-top boxes that operate according to the Data-over-Cable Service Interface Specifications (DOCSIS). DOCSIS supports the 6-MHz North American channel plans using the ITU J.83 Annex B RF standard. The downstream uses a 6 MHz channel width in the 85- to 860-MHz frequency range, and the upstream supports the 5- to 42-MHz frequency range.
Note The Cisco uBR-MC16S main board also includes a daughter card that provides the advanced hardware-based spectrum management feature. This daughter card is an integral part of the card assembly and cannot be removed in the field.
–Cisco uBR-MC16E supports cable modems and set-top boxes that operate according to the European DOCSIS specifications (EuroDOCSIS). EuroDOCSIS supports the 8 MHz Phase Alternating Line (PAL) and SEquential Couleur Avec Memoire (SECAM) channel plans using the ITU J.112 Annex A RF standard. The downstream uses an 8 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 65 MHz frequency range.
•Cisco Line Card Processor (Cisco uBR10-LCP2) adapter card—Provides the mechanical and electrical conversions necessary for the Cisco uBR-MC16C, Cisco uBR-MC16S, or the Cisco uBR-MC16E cable interface line card to fit the form factor used in the Cisco uBR10012 universal broadband router chassis.
Note There are two types of Cisco uBR-LCP adapter cards, LCP and LCP2. The LCP is the original adapter card shipped with the Cisco uBR10-LCP-MC16xcard. (Installation information about the LCP adapter card also applies to the LCP2 adapter card.) The Cisco uBR10-LCP2 adapter card replaces the LCP adapter card. The upgrade to the Cisco uBR10-LCP2 increases the memory from 64- to 256-MB. The upgrade supports N+1 requirements when the card is used as a redundant or protect card. There are no problems with the original LCP version if the card is used as the operating card. See the Proactive Upgrade Field Notice number 18301 at the following URL:
