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:
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.
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, the Cisco uBR-MC16E, or the
Cisco MC16S cable interface line card to fit the form factor used in the Cisco uBR100012 chassis.
Note 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
URL:
http://www-tac.cisco.com/Support_Library/field_alerts/fn18103.html.
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 Figure 1
on page 3). The Cisco uBR10-LCP2 not only adapts the cable interface line card to the form factor of
the Cisco uBR10012 chassis, but also provides:
Proper voltage conversion for the cards and chassis.
Boot code required to use the cable interface line cards.
SDRAM for buffering packets as they are transferred between the card and PRE1.

OL-2872-02
Cisco uBR10-LCP2-MC16C/MC16E/MC16S Overview
The cards are inserted into and removed from the Cisco uBR10012 chassis as a single logical and
physical unit. All Cisco uBR10-LCP2-MC16x cable interface line cards support online insertion and
removal (OIR). OIR uses the MAC address assigned to the Cisco uBR10-LCP2 adapter card, allowing
you to replace any Cisco uBR-MC16x cable interface line card installed on the adapter card without
losing the configuration information.
Note Do not attempt to separate or remove the cable interface line card from the Cisco uBR10-LCP2 adapter
card while they are 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. See the
“Replacing the Line Card in the Cisco uBR10-LCP2 Adapter Card” section on page 23.
Figure 1 shows the Cisco uBR10-LCP2-MC16C cable interface line card.

DOCSIS and EuroDOCSIS Data Rates and Modulation Schemes

Cisco cable interface line cards are configured in a number of different upstream combinations based on
the card used, your cable network, and the anticipated subscription and service levels. Table 2 lists the
data rates and modulation schemes for both DOCSIS and EuroDOCSIS standards.

Cisco uBR10-LCP2-MC16C

The Cisco uBR10-LCP2-MC16C cable interface line card output is +42 dBmV +/– 3 dB and supports
all DOCSIS upstream channel widths described in Table 2. The card is configured identically to the
Cisco uBR-MC16C cable interface line card.
Note The configuration information for the Cisco uBR10-LCP2-MC16C is the same as the information for the
Cisco uBR10-LCP2-MC28C/Cisco uBR-MC28C, except that there are fewer upstream and downstream
ports. Refer to the configuration guides.
For Cisco IOS software requirements see the “Obtaining Documentation” section on page 29.

Cisco uBR10-LCP2-MC16C/MC16E/MC16S Overview

Cisco uBR10-LCP2-MC16E

The Cisco uBR10-LCP2-MC16E cable interface line card output is +40 dBmV +/– 3 dB and supports
all EuroDOCSIS upstream channel widths described in Table 2 on page 4. The card is configured
identically to the Cisco uBR-MC16E cable interface line card.
While all other Cisco cable interface line cards transmit downstream signals to upconverters by using
the 44-MHz frequency, the Cisco uBR10-LCP2-MC16E transmits downstream IF signals to an up
converter by using the 36.125-MHz frequency.
For Cisco IOS software requirements see the “Obtaining Documentation” section on page 29.
For configuration information, refer to Configuring the Cisco uBR7200 Series MC16E Cable Modem
Card, available on the documentation CD-ROM and Cisco.com or at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/cable/cab_r_sw/index.htm
Refer to Chapter 3 in the Cisco uBR7200 Series Universal Broadband Router Software Configuration
Guide at the following URL:

Cisco uBR10-LCP2-MC16S

The Cisco uBR10-LCP2-MC16S:
Consists of the Cisco uBR10-LCP2 adapter card, a motherboard (based on the Cisco uBR-MC16C
cable interface line card) and an additional “piggy-back” spectrum management daughter card. The
card is configured identically to the Cisco uBR-MC16S cable interface line card.
Supports all DOCSIS downstream symbol rates and upstream channel widths as described in Tab l e 2
on page 4.
Features advanced spectrum management capabilities made possible by hardware and software
enhancements. The advanced spectrum management capabilities of the Cisco uBR10-LCP2-MC16S
include the ability to hierarchically scan portions of the upstream spectrum for clean channels of
varying widths.
The Cisco uBR10-LCP2-MC16S spectrum management card (daughter card) is able to sample the 5 to
42 MHz upstream frequency spectrum and initiate frequency hops, modulation change, or channel-width
changes based on the sampled information. When specified thresholds have been reached, the spectrum
management card takes a snapshot of the available upstream spectrum and then passes this information
to the Cisco IOS software, where it is analyzed for indications of significant ingress or impulse noise.
From this analysis, the Cisco IOS software draws informed conclusions regarding the “cleanest”
portions of the upstream frequency spectrum to initiate a frequency hop to a clean upstream channel, if
warranted. The user-defined threshold values are specified by commands in the configuration file of the
Cisco uBR10012 router.
For Cisco IOS software requirements see the “Related Documentation” section on page 28.

Safety Information and Warnings

Safety Information and Warnings
Following are safety guidelines that you should follow when working with any equipment that connects
to electrical power.
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:
Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
Disconnect all power and external cables before moving a chassis.
Do not work alone when potentially hazardous conditions exist.
Never assume that power has been disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are
improperly handled, can result in complete or intermittent failures. The AC-input power shelf and its AC
power modules contain a printed circuit card that is fixed in a metal carrier. Electromagnetic interference
(EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps
to protect the cards from ESD, use an antistatic strap each time you handle the modules.
