Cisco uBR10-LCP2-MC16C/MC16E/MC16S Overview
Cisco uBR10-LCP2-MC16C/MC16E/MC16S Overview
The cable 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-MC16C, the Cisco uBR10-LCP2-MC16E, and the Cisco-LCP2-MC16S cable
interface line cards are a combination of two components:
•
•
Note
The Cisco uBR10-LCP2 and Cisco uBR-MC16x cable interface line cards (MC16C, MC16E, and
MC16S) are mechanically connected to each other by using brackets and power connectors (see

the Cisco uBR10012 chassis, but also provides:

Cisco uBR-MC16x (MC16C, MC16E, and MC16S) cable 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.
The Cisco uBR-MC16S main board also includes a daughter card that provides the advanced
Note
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, the Cisco uBR-MC16E, or the
Cisco MC16S cable interface line card to fit the form factor used in the Cisco uBR100012 chassis.
Currently there are two types of LCP adapter cards, LCP and LCP2. The LCP is the original
adapter card shipped with the Cisco uBR10-LCP-MC16x card. (Installation information about
the LCP adapter card also applies to the LCP2 adapter card.) The Cisco uBR10-LCP2 adapter
card is replacing the old 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 is no problem 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
