Note The Cisco uBR-MC88V cable interface line card requires the new uBR7246VXR fan tray as part of its hardware. The part number for the new fan tray is MAS-U7246VXR-FAN2.
Restrictions for Configuring the Cisco uBR-MC88V Cable Interface Line Card
Online insertion and removal (OIR) or hot swapping between two Cisco uBR-MC88V line cards is supported in Cisco IOS Release 12.2(33)SCD. However, OIR between line cards of different types is not supported. That is, if you replace an existing Cisco uBR-MC28U line card with the Cisco uBR-MC88V line card, you must reconfigure the line card.
Note We recommend that you reload the Cisco uBR7246VXR or Cisco uBR7225VXR router when replacing a cable interface line card with a card of a different type.
You cannot install any of the existing line cards along with the Cisco uBR-MC88V line card in Cisco IOS Release 12.2(33)SCD.
You cannot configure a bonded channel using the channels of multiple cable interface line cards. A bonded channel must be configured using the channels of the same line card.
Note Note: We cannot bond across cards and cannot make a cable interface (Mac domain) across cards. Channel bonding can be done only on the same card.
The Cisco uBR-MC88V cable interface line card supports the Advanced Encryption Standard (AES) only when the Baseline Privacy Interface Plus (BPI+) is enabled.
Information About the Cisco uBR-MC88V Cable Interface Line Card
The Cisco uBR-MC88V cable interface line card serves as the RF interface between the cable headend and the DOCSIS-compliant cable modems, EuroDOCSIS-compliant cable modems, or set-top boxes (STBs). The Cisco uBR-MC88V cable interface line card has eight RF upstream (US) and two downstream (DS) physical connectors. Each downstream physical connector includes four downstream channels. The Cisco uBR-MC88V line card supports two cable interfaces (MAC domains), and the downstream and upstream channels are dynamically associated with any of these MAC domains.
Upstream data, from the subscriber, comes through the upstream ports (US0–US7) on the Cisco uBR-MC88V cable interface line card. The line card then processes and configures the data and sends it across the backplane to the WAN or backhaul card (or both), and out to the Internet.
Downstream data, to the subscriber, comes from the Internet through the WAN or backhaul card (or both), and across the backplane to the Cisco uBR-MC88V cable interface line card. The Cisco uBR-MC88V line card processes and configures the data and sends it out through the appropriate radio frequency channel on a downstream port (DS0–DS1) to be combined with the rest of the downstream signals in the headend.
The Cisco uBR-MC88V cable interface line card supports both DOCSIS and EuroDOCSIS cable modem networks. The card supports downstream channels in the 69 to 999 MHz range, and upstream channels in the 5 to 55 MHz range. The Cisco uBR-MC88V cable interface line card supports Annex B and Annex A data rates, channel widths, and modulation schemes, and has DOCSIS MAC management and spectrum management capabilities. This card also supports DOCSIS 3.0, A-TDMA, S-CDMA, downstream bonding, and upstream bonding rates.

The Cisco uBR-MC88V cable interface line card provides the following benefits:
Additional flexibility for cable operators in partitioning the cable plant to address growing subscriber bandwidth demands; enables cost-effective scalability of services and subscribers.
Hardware-based support for DOCSIS 2.0 (apart from DOCSIS 1.1 features) and DOCSIS 3.0 features such as S-CDMA, Upstream Channel Bonding, and other DOCSIS 3.0 downstream features.
Stacking Number Configuration
A new command, rf-channel stacking, was introduced in Cisco IOS Release 12.2(33)SCD to suppress a carrier or mute an RF channel on the Cisco uBR-MC88V line card. By default, the stacking number is configured as 4. If you change the default stacking number configuration, traffic loss may occur on the active channels. That is, if you change the stacking number from 4 to 2, traffic is interrupted on the RF channels 0 and 1.
However, traffic loss does not occur if you do not change the stacking number configuration when shutting down an RF channe l using the rf-channel rf-shutdown command.
Note We recommend that you do not change the default stacking number configuration. You can change the default configuration when you want RF diagnostics performed on a particular channel. For example, if you want to perform RF diagnostics on RF channel 2, you need to change the default stacking number configuration to 2 to completely mute this channel.
For more information about the rf-channel stacking command, see the Cisco IOS CMTS Cable Command Reference at the following URL:
The Onboard Failure Logging (OBFL) feature enables storage and collection of critical failure information in the NVRAM of the line card. The Cisco uBR-MC88V cable interface line card supports OBFL in Cisco IOS Release 12.2(33)SCD and later.
The OBFL stored data assists in understanding and debugging field failures upon Return Material Authorization (RMA) of a field-replaceable unit at repair and failure analysis sites.
OBFL records operating temperatures, voltages, hardware uptime, and any other important events that assist onboard diagnosis in case of hardware failures.
For more information on the feature, see the Onboard Failure Logging feature guide located at the following URL:
Note The sample output documented in the Onboard Failure Logging feature guide might slightly vary for Cisco CMTS routers.
How to Configure the Cisco uBR-MC88V Cable Interface Line Card
This section describes the steps for configuring the Cisco uBR-MC88V line card at startup. These procedures provide only the initial, basic configuration for the line card.
The universal broadband router must be operational before beginning the following basic configuration procedures for the line card:
Configuring an Integrated Cable Controller Interface on the Cisco uBR-MC88V Line Card
Every downstream port on the Cisco uBR-MC88V line card is configured as an integrated cable controller. Every Cisco uBR-MC88V line card can have up to two integrated cable controllers. You will have to configure all RF channel parameters such as downstream channel ID, frequency, and modulation rates on the controller interface.
Assigns a downstream channel ID to an RF channel in controller configuration mode.
rf-port— RF channel number on the physical port of the line card. The valid range is from 0 to 3.
channel-id—Unique channel ID. The valid range is from 1 to 255.
Note We recommend you to retain the system-generated default channel IDs instead of configuring it.
Step 5
rf-channel rf-port frequency { freq | none } [ annex { A | B } modulation { 64 | 256 } [ interleave-depth value ]]
Router(config-controller)# rf-channel 0 frequency 453000000 annex B modulation 256 interleave-depth 32
Configures the frequency of an RF channel in controller configuration mode.
rf-port—RF channel number on the physical port of the line card. The valid range is from 0 to 3.
freq—Center frequency for the RF channel. The valid range for each RF channel is different based on the Annex type.
none—Removes the specified frequency if the RF channel is shut down.
annex {A | B}—Indicates the MPEG framing format for each RF channel.
– A—Annex A. Indicates that the downstream is compatible with the European MPEG framing format specified in ITU-TJ.83 Annex A.
– B—Annex B. Indicates that the downstream is compatible with the North American MPEG framing format specified in ITU-TJ.83 Annex B.
modulation {64 | 256}—Indicates the modulation rate (64 or 256 QAM) for each RF channel.
interleave-depth value—Indicates the downstream interleave depth. For annex A, the interleave value is 12. For annex B, the valid values are 8, 16, 32, 64, and 128.
Note When the frequency, annex, or modulation is changed, it is reflected across all RF channels in the port. The frequency is automatically assigned using the 6 Mhz or 8 Mhz range based on the annex. The range of the frequency depends on the RF channel being configured.
Sets the RF power output level in the controller integrated cable mode. The RF power for an RF channel is based on the power mode.
rf-port—RF channel number on the physical port of the line card. The valid range is from 0 to 3.
power-level—Desired RF output power level in dBmV. The valid range is from 44 to 63 dBmV. The format is XY.Z. By default,.Z is added as.0. There are four modes of power levels. Mode indicates the number of RF channels enabled on the physical port. The RF channel stacking number configuration determines the power mode on the Cisco uBR-MC88V line card.
– Single Mode: The RF channel stacking number equals to 1 in this mode. The valid range is from 45 to 63 dBmV. (Channel 0 is enabled while the other channels are disabled.)
– Dual Mode: The RF channel stacking number equals to 2 in this mode.The valid range is from 48 to 56 dBmV. (Channels 0 and 1 are enabled; channels 2 and 3 are disabled.)
– Tri Mode: The RF channel stacking number equals to 3 in this mode. The valid range is from 46 to 54 dBmV. (Channels 0, 1, and 2 are enabled; channel 3 is disabled.)
– Quad Mode: The RF channel stacking number equals to 4. The valid range is from 44 to 52 dBmV. (Channels 0, 1, 2, and 3 are enabled.)
Step 7
no rf-channel rf-port rf-shutdown
Router(config-controller)# no rf-channel 0 rf-shutdown
Enables the RF channel.
Step 8
end
Router(config-controller)# end
Exits controller configuration mode and returns to privileged EXEC mode.
Example
The following example shows how to configure an integrated cable controller interface on the Cisco uBR-MC88Vline card:
Router(config-controller)# no rf-channel 3 rf-shutdown
Router(config-controller)# end
Note When you specify the RF channel parameters for the first RF channel on the integrated cable controller, all RF channel parameters except the interleave depth value are autoconfigured for the rest of the RF channels that are shared on the integrated cable controller. For example, if the frequency on RF channel 0 is configured, the frequency on the other RF channels are automatically configured based on the frequency value of RF channel 0.
Configuring a Cable Interface on the Cisco uBR-MC88V Line Card
