The Cisco uBR10-MC5x20U/H Broadband Processing Engine is one of the new Broadband Processing Engine (BPE) series of cable interfaces that are available for the Cisco uBR10012 universal broadband router. The BPE cards provide increased performance and advanced radio frequency (RF) management, as well as innovative, integrated tools for sophisticated content, traffic and network management.

The Cisco uBR10-MC5X20U/H BPE is a cable interface line card for the Cisco uBR10012 router that performs cable modem termination system (CMTS) functions, such as:

•Physical layer (PHY) radio frequency (RF) interface (upstream burst demodulation, downstream modulation, RF upconversion)

•Media Access Control (MAC) processing (modem registration, transmission opportunity scheduling, Layer 2 quality of service [QoS])

•On-board packet processing

Featuring a highly integrated and robust RF front end and the industry's most advanced processing engine for DOCSIS- and EuroDOCSIS-based networks, the Cisco uBR10-MC5X20U/H BPE enables high-performance, reliable, and secure bidirectional transmission of IP packets over the cable plant for data, voice, and video services.

The Cisco uBR10-MC5X20U/H BPE supports HCCP N+1 Redundancy in the Cisco cable modem termination system (CMTS). N+1 Redundancy is made possible with the addition of the Cisco RF Switch to your cable headend network.

Together with the Cisco uBR10012 router, the Cisco RF Switch and the Cisco uBR10-MC5X20U/H BPE provide a fully redundant system that enables cable operators to achieve PacketCable system availability, minimize service disruptions, and simplify operations. N+1 Redundancy is an important step toward high availability on CMTS and telecommunications networks that use broadband media. Further information about HCCP N+1 Redundancy is described in the "Additional References" section.

BPE Reconfiguration to Cisco uBR10-MC5X20

If you replace a Cisco uBR10-MC5X20U/H BPE with a Cisco uBR10-MC5X20U/H cable interface line card in the Cisco uBR10012 router chassis, you must reconfigure the line card.

Note Beginning in Cisco IOS Release 12.3(17b)BC4, you no longer need to reconfigure the line cards when you replace one card with another. Instead, use the cr10k card 7/0 oir-compatibility global configuration command.

Domains for Downstream and Upstream Ports

The configuration of the downstream and upstream ports is fixed into the five domains that are listed in Table 2.

Symbol Rate Changes

When changing the symbol rate on the Cisco uBR10-MC5X20U/H BPE, the show controller cable upstream command may show "US phy SNR_estimate - Unknown" for a brief period of time. Wait a moment and reissue the command to obtain an accurate Signal-to-Noise Ratio (SNR) value.

Also refer to the show controllers cable command in the Cisco CMTS Cable Command Reference.

Information About Configuring the Cisco uBR10-MC5X20U/H BPE

The Cisco uBR10-MC5X20U/H BPE supports downstream and upstream traffic over a Data-over-Cable Service Interface Specification (DOCSIS)-based cable modem network. The 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. The card supports downstream channels in the range from 54 to 860 MHz, an upstream range from 5 to 65 MHz, and a downstream center frequency configurable in 12.5-KHz increments; however, cable modems may be unable to locate the DOCSIS signal if the configured frequency is non-standard.

The Cisco uBR10-MC5X20U/H BPE contains five downstream ports and twenty upstream ports. Each downstream port includes an onboard integrated upconverter that generates an RF signal suitable for connection to a combiner and transmission on the coaxial cable network, without the need for any external upconverters.

In Cisco IOS Release 12.2(15)BC2 and later releases, the downstream ports support 64-Quadrature Amplitude Modulation (QAM) and 256-QAM, and the upstream ports support Quadrature Phase Shift Keying (QPSK), 8-QAM, 16-QAM, 32-QAM, and 64-QAM modulation, depending on the upstream's mode of operation. The upstream ports are initially configured to form five DOCSIS MAC domains, with each downstream port having four upstream ports. However, in Cisco IOS Release 12.2(15)BC2 and later releases, you can use the Virtual Interface feature and frequency stacking to configure upstream ports as desired.

Depending on the configuration, the Cisco uBR10-MC5X20U/H BPE supports either DOCSIS or Euro-DOCSIS operation:

•DOCSIS cable networks are based on the ITU J.83 Annex B physical layer standard and Data-over-Cable Service Interface Specifications (DOCSIS, Annex B) specification, which use 6-MHz National Cable & Telecommunications Association (NCTA) channel plans. In this mode, the downstream uses a 6-MHz channel width in the 88 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 42 MHz frequency range.

•EuroDOCSIS cable networks are based on the ITU J.112 Annex A physical layer standard and European DOCSIS (EuroDOCSIS, Annex A) specification, which use 8-MHz Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans. In this mode, the downstream uses an 8-MHz channel width in the 108 to 862 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 65 MHz frequency range.

Note You cannot support both Annex A and Annex B on one line card. If one is supported, the other must be restricted.

Within one chassis, however, you can have some cards that support Annex A, and some cards that support Annex B.

When operating in either the DOCSIS or EuroDOCSIS mode of operation, the Cisco uBR10-MC5X20U/H BPE supports the following types of networks:

•Time Division Multiple Access (TDMA)-only mode, which supports all DOCSIS cable modems but only using DOCSIS 1.0/1.1 channel widths and modulation schemes.

•A-TDMA-only mode, which supports DOCSIS 2.0 cable modems only.

•Mixed TDMA/A-TDMA mode, which supports both DOCSIS 1.0/1.1 and DOCSIS 2.0 cable modems on the same upstream with different modulation schemes, but only as high as 3.2 MHz channel width.

Note The Cisco uBR10-MC5X20U/H card also supports the extended frequency ranges that are used in Japanese Annex B networks: 70 to 860 MHz (downstream) and 5 to 55 MHz (upstream).

For information on installing the Cisco uBR10-MC5X20U/H card, see the Cisco uBR10-MC5X20S/U/H Cable Interface Line Card document on Cisco.com.

The Cisco uBR10-MC5X20U/H BPE supports all DOCSIS 1.1-specified Annex A, Annex B, and Euro-DOCSIS radio frequency (RF) data rates, channel widths, and modulation schemes. Table 1 shows the supported DOCSIS data rates.

The Cisco uBR10-MC5X20U/H BPE is available withdense connectors. Each type of card contains a color-coded label that identifies the downstream and upstream ports. Figure 1 shows the front panels.

Figure 1 Cisco uBR10-MC5X20U/H BPE Front-Panel View (Dense Connectors)

The five downstream ports are labelled DS0 RF through DS4 RF. The RF label indicates that the port is outputting an RF signal from the port's integrated upconverter. The 20 upstream ports are labelled US0 through US19.

In Cisco IOS Release 12.2(15)BC2, each upstream (US) port is statically associated with a particular downstream (DS) port by default. Table 2 shows the association between the Cisco uBR10-MC5X20U/H BPE's physical port domains and the upstream and downstream ports associated with each domain. Table 2 also shows the interface label to use when referring to the port when using command-line interface (CLI) commands.

Note It is possible to change the association between US and DS channels with configurable MAC domains (also called virtual interfaces). Virtual interfaces (VIs) are supported on the Cisco uBR10-MC5X20U/H BPE with Cisco IOS Release 12.2(15)BC2 and later releases.

1 The X and Y in the CLI Cable Interface Label column refer to the physical card slot in which the card is installed. The value for X can range from 5 to 8, and the value for Y can be either 0 or 1.


For example, Table 2 shows the Cisco uBR10-MC5X20U/H BPE to be installed as follows:

•The slot is slot 5/1.

•The interface C5/1/3 contains domain #4.

•The downstream port is DS3 RF.

•The upstream ports are US12, US13, US14, and US15.

Therefore, to configure upstream US14, you would specify upstream U2 on cable interface 5/1/3 (interface c5/1/3 command).

Benefits of the Cisco uBR10-MC5x20U/H Broadband Processing Engine

•Expands the capacity of the Cisco uBR10012 universal broadband router, providing the highest port density available in Cisco cable interface line cards.

•Fully supports N+1 Redundancy with the Cisco uBR10012 router and Cisco RF Switch. This significantly increases the High Availability for the Cisco CMTS.

•Supports the A-TDMA Service feature, which provides support for DOCSIS 2.0 Advanced Time Division Multiple Access (A-TDMA) upstream modulation profiles on the Cisco uBR-MC16U/X, Cisco uBR-MC28U/X, and Cisco uBR-MC5X20U/H Broadband Processing Engine (BPE) cable interface line cards. This feature supplements the existing support for DOCSIS 1.0 and DOCSIS 1.1 Time Division Multiple Access (TDMA) modulation profiles.

•Includes integrated upconverters for each downstream port, removing the requirement for an external upconverter.

•Provides hardware-based support for DOCSIS 1.1 features such as concatenation, fragmentation, and payload headers suppression (PHS).

•Gives cable operators additional flexibility in partitioning the cable plant to address growing subscriber bandwidth demands; enables cost-effective scalability of services and subscribers.

•Supports most earlier Cisco cable interface line card features including online insertion and removal (OIR), allowing key system components to be added or removed without powering off the chassis.

•Interoperates with DOCSIS-compliant cable modems and other RF customer premises equipment (CPE) devices.

enable
Example: 
Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2  

configure terminal
Example: 
Router# configure terminal

Enters global configuration mode.

Step 3  

interface cableslot/subslot/port
Example: 
Router (config)# interface cable8/1/0

Enters interface configuration mode for the cable interface, where:

•slot/subslot—Specifies the physical card slot, where slot can range from 5 to 8, and subslot can be either 0 or 1.

•port—Specifies the downstream port for the domain. The port parameter can range from 0 to 4, and the initial domain, domain 1, uses downstream port 0.

Step 4  

cable downstream frequency down-freq-hz
Example: 
Router (config-if)# cable downstream 
frequency 96000000

Sets the fixed center frequency for the integrated upconverter for this domain's downstream RF carrier in Hz.

•down-freq-hz—The known center frequency of the downstream carrier in Hz (the valid range is from 55,000,000 to 858,000,000).

The usable range depends on whether the downstream is configured for DOCSIS or EuroDOCSIS operations:

–DOCSIS = 88,000,000 to 855,000,000 Hz (91-857 MHz)

–EuroDOCSIS = 112,000,000 to 858,000,000 Hz (112-858 MHz)

Note The digital carrier frequency is not the same as the video carrier frequency.

Step 5  

cable downstream modulation  
{64qam | 256qam}
Example: 
Router(config-if)# cable downstream 
modulation 256qam

(Optional) Sets the downstream modulation rate:

•64qam—Modulation rate is 6 bits per downstream symbol (default).

•256qam—Modulation rate is 8 bits per downstream symbol.

Step 6  

cable downstream interleave-depth  
{8 | 16 | 32 | 64 | 128}
Example: 
Router(config-if)# cable downstream 
interleave-depth 8

(Optional) Sets the downstream interleave depth, in number of rows of codewords. The default is 32 rows.

Note This command is only capable in Annex B mode. Annex A (EuroDOCSIS) uses only one interleave of 12 and is not configurable.

Step 7  

cable downstream channel-id id
Example: 
Router(config-if)# cable downstream 
channel-id 128

(Optional) Sets the downstream channel ID. The default value is the unique unit number that is assigned by the CMTS.

•id—Specifies a downstream channel ID. Valid values are from 0 to 255.

Step 8  

cable downstream rf-power power-level
Example: 
Router(config-if)# cable downstream 
rf-power 45

Sets the RF power output level, in dBmV, on the integrated upconverter.

•power-level—Desired RF output power level in dBmV. The valid range is from 45 to 63 dBmV, with a default of 58 dBmV for the Cisco uBR10-MC5X20U/H BPE.

Note The official range for acceptable power levels in the DOCSIS specification is from 50 to 61 dBmV. Cisco cable interfaces exceed the DOCSIS specification, but power levels outside the DOCSIS specifications should be used only in lab and test environments.

Step 9  

no cable downstream rf-shutdown
Example: 
Router(config-if)# no cable downstream 
rf-shutdown

Enables RF output on the integrated upconverter.

Step 10  

no shutdown
Example: 
Router (config-if)# no shutdown

Activates the downstream port on a cable modem card for digital data transmission over the cable plant.

Step 11  

cable upstream n frequency up-freq-hz
Example: 
Router (config-int) # cable upstream 3 
frequency 5000000

Enters a fixed frequency of the upstream radio frequency (RF) carrier for an upstream port. This sets the center frequency for the upstream in Hz.

•n—Specifies the upstream port number on the cable interface line card for which you want to assign an upstream frequency. Valid values start with 0 for the first upstream port on the cable interface line card. The valid range for port is from 0 to 3.

•up-freq-hz—The upstream center frequency is configured to a fixed value. The valid upstream frequency range is from 5 MHz (5,000,000 Hz) to 65 MHz (65,000,000 Hz). If you wish to have the Cisco CMTS dynamically specify a center frequency for the given upstream interface, do not enter any frequency value and assign a spectrum group as shown below.

 

or

  
cable upstream n spectrum-group 
group-number
Example: 
Router (config-int) # cable upstream 0 
spectrum-group 12

Assigns the upstream to a spectrum group that defines the valid range of upstream frequencies.

•n—Specifies the upstream port number. Valid values start with 0 for the first upstream port on the cable interface line card. The valid range for port is 0 to 3.

•group-number—Specifies the spectrum group for which you are defining a parameter value, or specifies the number of the spectrum group you wish to remove from your router configuration. Valid range is from 1 to 40.

Step 12 

Repeat Step 11 for each upstream port.

Repeat Step 11 for each upstream port, changing the port parameter from 0 through 3. You must configure each upstream with either a fixed center frequency or assign it to a spectrum group.

Step 13  

cable upstream n 
ingress-noise-cancellation interval
Example: 
Router (config-int) # cable upstream 0 
ingress-noise-cancellation 200

(Optional) Sets how often a line card should train its noise-cancellation circuitry so as to adjust to noise levels on the upstream.

Optionally repeat this command for each upstream port, changing the port parameter from 0 through 3.

•n—Specifies the upstream port number. Valid values start with 0 for the first upstream port on the cable interface line card. The valid range for port is from 0 to 3.

•interval—Specifies the triggering interval, in milliseconds. The valid range is 10 to 3000 milliseconds, with a default value of 200 milliseconds.

Note This step applies to the Cisco uBR10-MC5X20H only; the Cisco uBR10-MC5X20U does not support this configuration.

Step 14  

cable upstream n power-level dbmv
Example: 
Router (config-int) # cable upstream 0 
power-level -5

(Optional) Sets the input power level for the upstream in dBmV.

Optionally repeat this command for each upstream port, changing the port parameter from 0 through 3.

•n—Specifies the upstream port number. Valid values start with 0 for the first upstream port on the cable interface line card. The valid range for port is from 0 to 3.

•dbmv—Specifies the decibels per millivolt designating the upstream signal input power level. Valid range is -10 dBmV to +25 dBmV. The valid range for dbmv is from -10 to +25 dBmV, with a default of 0.

Channel Width (MHz) Range at CMTS (dBmV)
.2 -16 to 14
.4 -13 to 17
.8 -10 to 20
1.6 -7 to 23
3.2 -4 to 26
6.4 -1 to 29

Step 15  

no cable upstream n shutdown
Example: 
Router (config-int) # no cable upstream 0 
shutdown

Activates the RF carrier on the upstream port. Each upstream port must be activated to enable upstream data from the cable modems on your network to the Cisco uBR10012 router.

•n—Specifies the upstream port number. Valid values start with 0 for the first upstream port on the cable interface line card. The valid range for port is from 0 to 3.

Repeat this command for each upstream port, changing the port parameter from 0 through 3.

Note Use this configuration only for ports with modems attached. Always shut ports that have no connectivity and no modems attached.

Step 16 

Repeat Steps 3-14 for each domain.

Repeat Steps 3-14 in this procedure for each domain, changing the downstream port from 0 through 4.

Step 17  

exit
Example:

Router(config-if)# exit

Exits interface configuration mode, and returns you to global configuration mode.

Step 18  

copy running-config startup-config

or 

write memory
Example: 
Router# copy running-config startup-config

or 

Router# write memory

After configuring all domains, save your settings to the nonvolatile random access memory (NVRAM) to ensure that the system retains the settings after a power cycle

Examples

The following example shows how to complete a typical configuration for the first domain of the card installed in slot 8/0 in the Cisco uBR10012 chassis: 

Router# enable

Router# configure terminal

Shutting Down the Interface

Before permanently removing a Cisco uBR10-MC5X20U/H BPE from the Cisco uBR10012 chassis, use the shutdown command to shut down and disable the interface. When you shut down an interface, it is designated administratively down in the show command displays.

Note You do not need to shut down an interface when you are replacing the cable interface line card using online insertion and removal (OIR).

Use the following procedure to shut down an interface.

Legacy N+1 Configurations for Backward Compatibility

The following output from the Cisco IOS show running configuration command illustrates the configuration of N+1 Redundancy using the following CMTS:

•One Cisco 3x10 RF Switch configured as two Working RF Switches in 4+1 mode

•One Cisco uBR10012 router

•Five Cisco uBR10-MC5X20S/U/H broadband processing engines (BPEs)

The Protection mode affects the bitmaps of the Cisco RF Switch and CMTS configuration.

Note If you add one additional Cisco uBR10-MC5X20S/U/H BPE, the entire CMTS configuration below must be changed. Refer to the following documents for additional information:

•Cabling the Cisco uBR10-MC5X20S/U/H Cable Interface Line Card with Universal Cable Holder-UCH1

http://www.cisco.com/en/US/docs/interfaces_modules/cable/broadband_processing_engines/ubr10_mc5x20s_u_h/quick/start/MC52_cbl.html

•Cabling the Cisco uBR10-MC5X20S/U/H Cable Interface Line Card with Universal Cable Holder-UCH2

http://www.cisco.com/en/US/docs/interfaces_modules/cable/broadband_processing_engines/ubr10_mc5x20s_u_h/quick/start/MC52_cb2.html

Summary Steps for This Configuration

1. Take the header that says RF Switch 2 (top Switch) and leave in slots 1, 2, 3, and 4.

2. Take the header that says RF Switch 1 and place in slots 5, 6, 7, and 8 of RF Switch 2.

3. Take the Protect from RF Switch 2 and place in Protect 2.

4. Take the Protect from RF Switch 1 and place in Protect 1 of RF Switch 2.

5. Once you get to five uBR10-MC5X20S/U/H BPEs, the bitmap configuration needs to be changed and the headers moved from one Cisco RF Switch to the other. For example, the slot 5 header moves to the slot 1 header of Cisco RF Switch 1.

Additional Configuration Notes

•The configuration is labeled "Router(config-if)# cable downstream modulation 256qam " as pertaining to slots 1-4 and their respective Protect slot, which is Protect 2.

•Protect 1 covers slots 5-8 on the Cisco RF Switch and is labeled as "Router(config-if)# cable downstream interleave-depth 32 ." In the 4+1 mode the RF Switch slots 5-8 are considered to be slots 1-4 for configuration purposes.

•These configurations are for MAC interface switchovers. Bear in mind that the entire JIB (ASIC) switches over when circumstances require. DS channels 0 and 1 share the same ASIC, DS channels 2 and 3 share the same ASIC, and DS channel 4 is on its own ASIC. If an interface does not have Hot Standby Connection-to-Connection Protocol (HCCP) configured, it will not switch over even if it does share the same JIB with an HCCP interface.

•If using the keepalive command on HCCP interfaces that share a common ASIC, we recommend that you configure no hccp g revertive on the respective Protect interfaces. For additional information, refer to the topic "Disabling HCCP Revertive on Protect Cable Interfaces" in the document titled N+1 Redundancy for the Cisco Cable Modem Termination System on Cisco.com:
