The Cisco uBR10012 universal broadband router provides a high-end, high-performance, high-capacity Cable Modem Termination System (CMTS) solution. The Cisco uBR10012 router is an aggregation platform that places a new level of intelligence and performance at the edge of the network, enabling cable service providers to maximize their revenues by delivering more feature-rich services to their customers. The system can provide high-speed data, broadband entertainment, and IP telephony services to residential and commercial subscribers using cable modems or digital set-top boxes (STBs).
The Cisco uBR10012 router is based on the Data-over-Cable Service Interface Specifications (DOCSIS), which were developed by a cable industry initiative to ensure the reliable and secure operation of cable data networks. The router can interoperate with cable modems or STBs that support the DOCSIS 1.0, DOCSIS 1.1, EuroDOCSIS 1.1, DOCSIS 2.0, DOCSIS 3.0 and EuroDOCSIS 2.0 versions of the DOCSIS specification.
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. Each chassis can support multiple standards and multiple interfaces, allowing operators to choose the appropriate services and devices that optimize their capital investment with a single CMTS platform.
The Cisco uBR10012 router supports data and digitized voice connectivity over a bidirectional cable television and IP backbone network, using advanced quality of service (QoS) techniques to ensure that real-time traffic such as voice can be reliably delivered, while still transmitting other traffic on a best-effort basis. The Cisco uBR10012 router concentrates traffic from two-way DOCSIS-based cable modems and STBs that is transmitted over the coaxial cable television (CATV) network, and presents that traffic to local and remote Internet Protocol (IP) hosts over its high-speed network uplink interfaces.
The Cisco uBR10012 universal broadband router uses the same Parallel Express Forwarding (PXF) technology used by the Cisco ESR10000 edge services router. The combination of PXF technology with Cisco's CMTS solutions creates a cost-effective, scalable, and industry-proven CMTS that provides consistent, high-performance throughput that is optimized for high-volume traffic over a cable network.
Based on the Cisco IOS networking software, the router supports the most advanced networking and routing options. Also, with access to current and future software enhancements, the router ensures investment protection as standards and customer needs continue to evolve.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030.
Cisco uBR10012 Router Features
The Cisco uBR10012 router has the following features:
– PRE1 modules support error checking and correction (ECC) for all onboard memory, replacing the simpler parity error algorithm of the original PRE module.
– PRE2 modules are designed to address Internet-service-provider (ISP) requirements. The PRE2 provides 6.2 mpps of processing power and has a 500-MHz RM7000 mips processor with integrated 16-KB data and 16-KB instruction Level 1 caches integrated 256-KB Level 2 cache, and 4-MB Level 3 cache. Cisco IOS Release 12.3(9)BC.
– The PRE4 is the fifth generation Parallel Express Forwarding (PXF) packet processing and scheduling engine for the Cisco uBR10012 router. The PRE4 provides 10 mpps of processing power and has a 800-MHz dual processor with a 512-MB packet buffer and a 128-MB control memory with error-correcting code. Cisco IOS Release 12.3(33)SB.
Note When replacing a PRE1 module with a PRE2 module, you must also install EMI gaskets and RF absorber material, for more information, go to the following URL:
Two timing, communication, and control plus (TCC+) modules —each TCC+ card provides a connector for an external clock reference source, with a second connector for a backup clock source. See “Timing, Communication, and Control Plus Card”.
– Variable speed levels. The operating speed of the fan is determined by the temperature of the facility.
– Multiple fans in the fan assembly provide redundancy to support single failure.
– Status LEDs on the fan assembly indicate single or multiple fan failure.
– Replacing the fan assembly module does not interrupt service (within certain time limits).
Comparisons with Other Cisco CMTS Platforms
The Cisco uBR10012 router is a next-generation CMTS platform with the following significant differences from the other Cisco CMTS platforms (Cisco uBR7100 series and Cisco uBR7200 series universal broadband routers):
The Cisco uBR10012 router supports a larger form factor for cable interface line cards. The existing cable interface line cards for the Cisco uBR7200 series routers cannot be used with the Cisco uBR10012 router.
The Cisco uBR10012 router uses high-performance PRE modules as its processor cards. It does not use any of the network processor cards used on the Cisco uBR7200 series router.
The Cisco uBR10012 router is a high-performance, high-throughput CMTS router that requires high-performance network uplink line cards for its WAN connectivity to the Internet and other connected networks. It does not use any of the port adapters that are available for the Cisco uBR7100 series and Cisco uBR7200 series router.
The Cisco uBR10012 router does not use the Cisco cable clock card because the TCC+ cards include national clock support.
To accommodate the new architecture of the Cisco uBR10012 chassis, slot numbering on the router has been expanded to include a card and subcard numbering system (1/0, 2/0, and so forth). See Figure 1-4 for a diagram of the slot numbering on the Cisco uBR10012 chassis.
Cisco uBR10012 Router Functional Overview
The Cisco uBR10012 router is a cable modem termination system (CMTS) that provides Internet, LAN, and WAN access for cable modems and set-top-boxes (STBs) over a coaxial cable connection. The router enables high-speed data services to be packaged like they are in basic cable television service or video programming.
The path from the CMTS to the cable modem or STB is the downstream, which carries the majority of traffic over the cable interface. The path from the cable modem or STB to the CMTS is the upstream, and it typically carries approximately 10 percent of the traffic that is sent over the downstream. A large number of users can be assigned to the same downstream, and for efficient use of bandwidth, those users can be split among several different upstreams.
The following sections provide a high-level overview of the data path over the upstream and the downstream.
Upstream Data Path
The following example describes the upstream data path.
1. A request for service is generated by a subscriber. The modem transmits the request as a series of packets to the CMTS on the upstream.
2. The cable line card receives the packets on its upstream interface and forwards them to its onboard processor.
3. The line card’s processor verifies the header check sequence (HCS), frame check sequence (FCS), and system identification number (SID), processes all fields in the DOCSIS MAC header, and then removes the header.
a. The line card examines and processes the extended headers (Request, Acknowledgement, Privacy, PHSs and Unsolicited Grand Synchronization header elements). If Baseline Privacy Interface (BPI) is used, the processor also decrypts the Privacy EH frames using the appropriate key.
b. Bandwidth requests, acknowledgment (ACK) requests, and unsolicited grant syncs are reformatted and passed to the request ring of the Cisco cable line card.
c. The DOCSIS MAC header is removed and another header is added, which includes the SID, the upstream port information, and status bits that indicate whether any errors were detected.
4. The packet is sent across the backplane to the forwarding processor (FP) or the routing processor (RP) on the PRE.
5. The PRE performs packet operations such as access list processing, classification, switching, and QoS. It is also where major routing and IOS management functions (filtering) are run.
6. The packet is moved to the correct output queue and transmitted over the backplane to the network uplink card (OC-48 DPT/POS, GigE) or another cable interface line card.
7. The output card forwards the packet to the next interface point.
Downstream Data Path
The following example describes the downstream data path.
1. Data packets from the Internet are received by the network uplink cards (OC-48 DPT/ POS, GigE).
2. The packets are forwarded to the file processor (FP) on the PRE module.
3. The FP performs MAC classification to determine the type of frame or packet to be processed.
4. The PRE performs access list filtering, policing, and marking.
5. A forwarding information base (FIB) lookup and rewrite happens.
a. The rewrite consists of a downstream header and 802.3 MAC header.
b. The downstream header contains destination primary SID, physical DS port number, PHS rule index, and some control bits and other fields.
c. The packet is policed, shaped and prepared for queueing. Queueing is based on the priority of the queue and the state of the flow bits from the card. The destination card address (port) is prepended on the header of the packet being transmitted.
6. The packet is transmitted over the backplane to the appropriate cable interface line card.
7. The cable interface line card receives the packet and forwards it to all the ASICs on the line card.
a. Each ASIC decodes the header to determine if the packet is destined for one of the downstream ports on that card. If so, the downstream header is removed and the 802.3 MAC header is saved.
b. The MAC header is processed to determine how to build the DOCSIS MAC header and what operations to perform on the packet. These might include prepending the DOCSIS MAC header, computing the HCS and FCS, performing Packet Header Suppression, and BPI encryption.
8. Once the packet is ready, it is immediately transmitted on the downstream.
Cisco uBR10012 Router and Cisco IOS Software
The Cisco uBR10012 router runs the Cisco IOS software, which is stored on the Type II PCMCIA flash memory disks stored in the two PCMCIA slots in the primary PRE module. A PCMCIA flash memory disk in either slot can store a Cisco IOS image or configuration file.
In addition to the flash memory disks, each PRE module contains onboard flash memory that is used to store a boot loader. The loader executes following a system reset to reload and execute the Cisco IOS software on the flash memory disks.
The PRE module also stores the system configuration in the onboard flash memory. The configuration information read from the flash memory is buffered in operational memory following initialization, and is written to the flash memory device when the configuration is saved.
Each line card also contains onboard flash memory that is used to store a boot loader, similar in function to that used on the PRE module. However, the line card loader executes following a system reset, line card reset, or line card insertion to reload and execute any code that must run on the line card.
Software images may also be stored on an external TFTP server. If the Cisco uBR10012 router is so configured, it then downloads the proper image from the TFTP server and executes it.
DOCSIS and EuroDOCSIS Data Rates and Modulation Schemes
Cisco cable interface line cards can be configured in a number of different upstream combinations based on the card used, your cable network, and the anticipated subscription and service levels.
Table 1-1 lists the data rates and modulation schemes for both DOCSIS1.1 and EuroDOCSIS 1.1 standards.
Table 1-2 lists the data rates and modulation schemes for DOCSIS 2.0 and EuroDOCSIS 2.0 standards.

NEBS Level 3 Compliance
The Cisco uBR10012 router is Network Equipment Building System (NEBS) Level 3 compliant. This includes the following categories:
This section describes the Cisco uBR10012 router and router components.
Cisco uBR10012 Router
The Cisco uBR10012 router is installed in a standard 19-inch equipment or telco rack. A rack-mount kit ships from the Cisco factory with each router. The rack-mount kit includes the hardware needed to mount the router in a standard 19-inch equipment rack or telco-type rack. Mounting in 23-inch equipment racks is possible with optional third-party mounting hardware.
The Cisco uBR10012 chassis is designed for front and rear access. The two AC or DC power entry modules (PEM)s, two Performance Routing Engine (PRE) modules, the LCD panel, and the fan assembly module are accessed from the front of the chassis, see Figure 1-2. The eight slots for cable interface line cards, four full-slots for network uplink line cards, and two slots for the Timing, Communication, and Control Plus (TCC+) cards, and DOCSIS Timing, Communication, and Control Plus (DTCC) cards are accessed from the rear of the chassis, see Figure 1-3.
Note If the only available power supply source is 100-120 VAC, you can use the auxiliary AC-input power shelf. The AC-input power shelf converts AC to DC power for the Cisco uBR10012 router. See “Supported External AC-Input Power Shelves” for more information.
Figure 1-1 shows the front of the Cisco uBR10012 router with the front cover installed.

Caution The handles shown on the left and right sides of the chassis should be used only when lifting a depopulated chassis that does not have any PEMs, fan assembly module, or line cards installed. See “Chassis-Lifting Guidelines” for more information.
Cisco uBR10012 Router Slot Numbering
Figure 1-4 shows the slot numbering for the line cards and TCC+ cards in the rear of the chassis. The Cisco uBR5X20S/U cable interface line cards are used in this Figure 1-4.
Note Half-height Gigabit Ethernet (HHGE) line cards use slot 3 and slot 4 only. These cards are used with a slot splitter that subdivides the slots so that they become slots 3/0/0, 3/0/1, and slots 4/0/0, 4/0/1.
Caution If you place a slot splitter and HHGE line card in slot 1/0 or slot 2/0, these slots shut down.
Figure 1-5 shows the slot numbering for the Fast Ethernet interface on the active PRE module.
Tip The Fast Ethernet interface on the backup PRE is not used unless the primary PRE fails and the backup PRE is activated. When the backup PRE becomes the active PRE module, its Fast Ethernet interface automatically becomes the active Fast Ethernet interface at slot 0/0.
Note The Cisco uBR10012 router also has an internal Ethernet interface, Ethernet 0/0/0, which PRE processors and line cards use to transfer packets between cards. This interface is not user-configurable, although you can see the configuration and run-time information using the show interface command.
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040
Cisco uBR10012 Universal Broadband Router Modules
The following section describes the modules used in the Cisco uBR10012 router. For a list of field replaceable units (FRUs) used in this chassis, see “Cisco uBR10012 Router FRU Resources”.
Fan Assembly Module
The Cisco uBR10012 chassis uses a fan assembly module containing fans to supply cooling air to the chassis. The fan assembly connects to the chassis through a blind mate connector that plugs into the cable assembly and then into the chassis backplane. The fan assembly modules can be identified by the product part numbers. The fan assembly module supported on the Cisco uBR10012 chassis is:
The Cisco uBR10012 router is shipped with two AC power entry modules (AC PEMs) that provide power supply to the system. One AC PEM module is sufficient to provide power for a fully configured chassis. However, if one AC PEM module fails, the other AC PEM module automatically begins providing power to the entire chassis, without impacting the system operation.
The AC PEM modules use a standard 200–240 VAC (50 or 60 Hz) input power obtained through power receptacles on the front panel of each PEM. The two AC PEMs convert the AC power to provide filtered, redundant, and load shared DC power to the Cisco uBR10012 chassis. The AC PEM modules can be identified by their product part numbers.
The AC PEM modules supported on the Cisco uBR10012 chassis are:
The Cisco uBR10012 router is shipped with two DC power entry modules (DC PEMs) that provide power to the system. One DC PEM can provide sufficient power for a fully configured chassis. However, if one DC PEM fails, the other automatically begins providing power to the entire chassis, without impacting the system operation.
The two DC PEMs provide filtered, redundant, and load shared DC power to the Cisco uBR10012 chassis. The DC PEM modules can be identified by their product part numbers.
The DC PEM modules supported on the Cisco uBR10012 chassis are:
DC PEM Module (UBR10-PWR-DC=)
DC PEM Module (UBR10-PWR-DC-PLUS=)
summarizes the specifications of the DC PEM modules.
2.The 34- part number is listed on compliance label of the DC PEM.
3.For the 34-1651-04 and 34-1651-05 DC PEM modules, the DC-output voltage varies according to the DC-input voltage with a drop in voltage between 1 V and 1.85 V. The allowable DC-input range is -40.5 V to -72 V. The DC-output voltage is not constant for these DC PEM modules. For the 341-0388-01 DC PEM module, the DC-output voltage is regulated and is constant.
If 100–120 VAC is the only available power source at the facility, then use the external AC-input power shelf with the Cisco uBR10012 router The AC-input power shelf converts AC power from an external AC power supply source into DC power that is suitable for powering on the Cisco uBR10012 router.
The external power shelves supported on the Cisco uBR10012 router are:
2400 W AC-Input Power Shelf
Lineage AC-DC Power Shelf
lists the specifications of the external power shelves on the Cisco uBR10012 chassis.
Table 1-5 Supported External Power Shelves for Cisco uBR10012 Router Specifications
5.The 34- part number is listed on the compliance label of the DC PEM.
For information on installation, power shelf safety features, safety warnings, and troubleshooting the Lineage power shelf, see the product documentation available at http://www.lineagepower.com/
Lineage AC-DC Power Shelf
This external AC-DC power shelf from Lineage (part number J85480S1 L30) with AC module (CP2000AC54PE) is 1-rack unit high (1.75 inch) and can be mounted on a standard 19-inch 4-post equipment rack or telco-type rack. We recommend installing the Lineage power shelf in the rack in a way that the power connections reside facing inside the rack when viewed from the front. This allows the DC output terminals of the external AC-input power shelf to be on the same side as the DC-input terminals of the Cisco uBR10012 chassis.
The Lineage AC-DC power shelf has two DC power sources, four AC-input power supply sources, and J1 and J2 connectors. Each AC-input power supply module is automatically powered on when it is plugged into the wall socket. (See Figure 1-6)
Figure 1-6 Lineage AC-DC Power Shelf - Front and Rear View
DC power source terminal blocks
AC input power connectors
J1 connector / alarm cable interface
All cable connections for AC-input power, DC-output power, and status signals are made from the rear of the power shelf. Each AC power supply module has an individual AC facility cord attachment. All four AC-input cords must be attached to the facility for all four AC power modules to function. Two DC-interconnect cables provide DC-output power to the DC PEM (UBR10-PWR-DC=) modules on the Cisco uBR10012 chassis. (See Figure 1-7)
Note The AC-input power cables, DC-output power cables, and alarm monitor cable are supplied along with Lineage. We recommend that you use these cables for cabling the shelf to the Cisco uBR10012 router.
Figure 1-7 Rear View of the Lineage AC-DC Power Shelf with Cables

AC power supply cables
To meet compliance standards, use the DC power cables (3 m cable supplied along with Lineage power shelf), while cabling the Lineage AC-DC power shelf to the Cisco uBR10012 chassis. Ensure proper rating and fit in the chassis when connecting the cables into the input DC terminal block on the backplane of the Cisco uBR10012 chassis.
The LCD module provides real-time operating status and configuration information for the chassis and line cards. The buttons below the screen provide a menu system that allows you to display different parts of the system configuration without using a terminal. Figure 1-8 shows the Cisco LCD module without the chassis front cover.
Figure 1-8 LCD Module Display Panel
NoteThe LCD module functions depend on the release of the Cisco IOS software running on your Cisco uBR10012 router. Refer to the release notes for the Cisco IOS release you are using, and the “$paratext>” section.
The LCD ribbon cable connects the LCD module to the backplane. The folded end is connected to the LCD module. See Figure 1-9.
Figure 1-9 LCD Cable
Performance Routing Engine
There are four models of PREs, the original PRE module that was initially shipped with the Cisco uBR10012 router, the PRE1 module that began shipping with Cisco IOS Release 12.2(4)XF, the PRE2 module that is shipping with Cisco IOS Release 12.3(9)BC, and the PRE4 module that is shipping with Cisco IOS Release 12.2(33)SB.
PRE1 functionality was introduced in Cisco IOS Release 12.2(4)XF.
PRE2 functionality was introduced in Cisco IOS Release 12.3(9a)BC.
PRE4 functionality was introduced in Cisco IOS Release 12.2(33)SCB.
You can use the CLI
command to determine whether a PRE, PRE1, PRE2, or PRE4 module is installed in your system.
Note The PRE3 is not supported on the Cisco uBR10012 router
The PRE is a single-slot module used with the Cisco uBR10012 routers. The PRE performs all Layer 2 and Layer 3 packet routing and forwarding using an advanced parallel processing architecture called Parallel eXpress Forwarding (PXF). This process separates the control plane from the data plane. The PXF architecture supports high-performance throughput with IP services enabled on every port.
Note When replacing a PRE1 module with a PRE2 module, you must also install EMI gaskets and RF absorber material. For more information, go to the following URL:
PRE1 modules support error checking and correction (ECC) for all onboard memory, replacing the simpler parity error algorithm of the original PRE module. A general-purpose RISC processor (262–300 MHz MIPS RISCMark RM7000) support high performance Layer 3 forwarding of traffic. The combination of a general purpose RISC processor with advanced programmable PXF network processors provides the capacity to support the aggregation of thousands of active connections in a single Cisco uBR10012 chassis when supporting IP applications such as access policy filtering, rate-based queuing, and QoS.
PRE2 modules are designed to address Internet service provider (ISP) requirements. The PRE2 has four PFX network processors (containing 64 individual processors) with two independent 32-MB SDRAM control memories on each processor set. The PRE2 provides 6.2 Mpps of processing power and has a 500-MHz RM 7000 mips processor with integrated 16-KB data and 16-KB instruction Level 1 caches, an integrated 256-KB Level 2 cache, and a 4-MB Level 3 cache.
Cisco IOS Release 12.3(9a)BC automatically enables the following features:
Route Processor Redundancy Plus (RPR+)
6.2 mpps processing power
Software features available with PRE2 and Cisco IOS Release 12.3(9a)BC:
– TLS 802.1q
The Performance Routing Engine 4 (PRE4) is the fifth-generation Parallel Express Forwarding (PXF) packet processing and scheduling engine for the Cisco uBR10012 router.
PRE4 enhances the performance capability of the Cisco uBR10012 router to 10 Mpps by providing increased density Gigabit Ethernet (GE) and higher throughput of the 10GE SPA interface.
The PRE4 runs Cisco IOS Release 12.2(33)SCB and later releases. Benefits of the PRE4 include:
800-MHz dual processor
64 PXF network processors arranged as 8 columns and 8 rows
512-MB packet buffer and 128-MB control memory with error-correcting code
4-GB ECC-protected Route Processor (RP) memory
10 million packets per second (Mpps) forwarding performance through the PXF complex
5.6-Gbps backplane bandwidth for each full-height backplane slot
11.2 Gbps backplane bandwidth to each SPA interface processor (SIP)
Maximum transmission unit (MTU) support of 9216 bytes
An external CompactFlash Disk slot (disk0)
A 100/1000 Megabit Ethernet interface for communication between redundant PRE4s
Note Unless otherwise indicated, all references in this document to the PRE refer to the PRE, the PRE1, the PRE2, or the PRE4 modules. The PRE is now end-of-life (EOL) and is replaced by the PRE1, PRE2, or PRE4.
Redundant PRE Modules
The PRE module supports redundant operation (two PRE modules in a Cisco uBR10012 chassis). If the primary PRE fails, the secondary PRE automatically takes over operation of the chassis. Because all Cisco uBR10012 line cards are physically connected to both the primary and secondary PRE modules, a switchover of PRE modules does not require human intervention to reset the line cards, as they automatically fail over to the redundant PRE. The PRE module is hot-swappable if there is a redundant PRE module in the chassis.
Caution You cannot use different models of the PRE in the same chassis. If you have PRE2 modules and you wish to upgrade, you must upgrade both of your PREs to the PRE4s. You cannot use a PRE1 or a PRE2 and a PRE4 in the same system.
PRE Module Description
The PRE1 contains two PC media card two slots and 64 MB of onboard flash memory. Figure 1-10 shows the PRE 1 faceplate.
Figure 1-10 PRE1 Faceplate
The PRE2 contains two PC media card slots and 128 MB of onboard flash memory. Figure 1-11 shows the PRE2 faceplate.
Figure 1-11 PRE2 Faceplate

The faceplate on the PRE contains three ports with RJ-45 connectors:
Console port—This asynchronous EIA/TIA-232 serial port is used to connect a terminal to the PRE for local administrative access.
Auxiliary port (AUX)—This asynchronous EIA/TIA-232 serial port is used to connect a modem to the PRE for remote administrative access.
Fast Ethernet port—This Fast Ethernet port is used to connect the PRE to a 10/100Base-T network management LAN.
Note The Fast Ethernet interface on the PRE module is intended for network management access and should not be used for WAN connectivity purposes. For WAN connections, use the appropriate network uplink cards, which take full advantage of the system's high-performance PXF processing subsystem.
PC Media Card Slots
Two PC media card slots (one CompactFlash Disk slot for the PRE4) can store the Cisco IOS image or a system configuration file on a PC media card or CompactFlash Disk. The system can also boot from the software stored on the PC media card or CompactFlash Disk. The PC media card slots support Type I or Type II cards. See the “$paratext>” section for more information about inserting and removing PC media cards from the PRE.
The two LCD screens below the PC media card slots display alphanumeric information about the status of the of the PRE module.
PRE LED Indicators and Buttons
LEDs on the faceplate of the PRE provide a visual indication of the status of PRE operation (see Figure 1-10). The LEDs are separated into three categories: alarms, status, and failure.
ALARM—Alarm relay contacts on the Cisco uBR10012 router connect the router to a site alarm maintenance system. This allows critical, major, and minor alarms generated by the Cisco uBR10012 router to be displayed on the PRE faceplate and also translated to external visual or audible alarms connected to the system. See the “Connecting Alarm Indicators” section for more information about alarm connections. Pressing the alarm cutoff (ACO) button on the (primary) PRE during an alarm condition shuts off the external alarm, but does not deactivate the alarm LEDs on the PRE faceplate. Alarm LEDs on the faceplate are deactivated only after the condition that caused the alarm is corrected.
STATUS—Indicates the status of the PRE.
FAIL—Indicates that a major failure has disabled the PRE.
Table 1-7 describes the LEDs and switch on the PRE.

6.The Cisco uBR10012 router supports PCMCIA flash memory cards of 64 MB or above.
PRE Module Disposal
The PRE module contains a small lithium battery. Some jurisdictions restrict the ways in which you can dispose of items containing lithium batteries. In particular, never dispose of lithium batteries or products containing lithium batteries in an unregulated fire. Other restrictions might apply in your area.
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040.
SIP and SPA Compatibility
The Cisco uBR10012 router currently supports the following SIPs:
Cisco Wideband SIP for the Cisco Wideband SPA
Cisco 10000 Series SPA Interface Processor-600
The Cisco Wideband SIP can support up to two Cisco Wideband SPAs. The Cisco uBR10012 router can support up to six SPAs. For more information about the introduction of support for different SIPs and SPAs, refer to the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration Guide at the following location:
On the Cisco uBR10012 router, the Timing, Communication, and Control Plus (TCC+) card acts as a secondary processor that performs the following functions:
Generates and distributes 10.24 MHz clock references to each of the cable interface line cards.
Generates and distributes 32-bit time-stamp references to each of the cable interface line cards.
Allows software to power off independently any or all of the cable interface line cards.
Drives the LCD module used to display system configuration and status information.
Monitors the supply power used by the chassis.
Provides two redundant RJ-45 ports for external timing clock reference inputs such as a Global Positioning System (GPS) or building integrated timing supplies (BITS) clock.
When two TCC+ cards are installed, they are configured as active and backup (redundant). If the TCC+ card in the first slot is working at system power-up, it automatically becomes the active card and the TCC+ card in the second slot becomes the backup card. The TCC+ cards monitor each other’s priority information so that if the active card fails, the active card role is transferred to the redundant backup card without lose of data.
Figure 1-13 shows the faceplate of the TCC+ card. The handle provides for the insertion and removal of the card from the chassis.
Caution Do not attempt to lift the chassis using one of these handles.

The faceplate on the TCC+ card has seven LEDs labeled POWER, STATUS, MAINT, PRESENT, and ACTIVE. Separate PRESENT and ACTIVE LEDs are associated with the primary and secondary external clock reference inputs.
On the Cisco uBR10012 universal broadband router, the DTCC card acts as a secondary processor that performs the following functions:
In the default DTI mode, a 10.24 MHz clock and 32-bit DOCSIS timestamp are generated by the DTI Server, propagated to DTI client using DTI protocol, and distributed by DTI client to each cable interface line card.
Allows software to independently power off any or all cable interface line cards.
Drives the LCD panel used to display system configuration and status information.
Monitors the supply power usage of the chassis.
Two RJ-45 cables with the DTI server, which, in turn, can generate the clock using its own oscillator or external timing reference inputs such as GPS or network clock.
Two DTCC cards are installed and configured as active (primary) and backup (redundant). If the DTCC card in the first slot is working at system power-up, it automatically becomes the active card and the DTCC card in the second slot becomes the backup card. The DTCC cards monitor each other’s priority information, so that if the active card fails, the active card role is transferred to the redundant backup card without loss of data.
The front panel on the DTCC card has seven LEDs. They are labeled POWER, STATUS, MAINTENANCE, PRESENT, and ACTIVE. The second set of PRESENT and ACTIVE LEDs are associated with the primary and secondary external clock reference inputs.
The Cisco uBR10-MC5X20S, U and H cable interface line cards are 20 by 16 inch cards designed specifically for the Cisco uBR10012 router. These cards transmit and receive RF signals between the subscriber and the headend over hybrid fiber-coaxial (HFC) system.
Upstream data, from the subscriber, comes through the upstream ports (US0-US19) on the Cisco uBR10-MC5X20S/U/H cable interface line card. The line card processes and configures the data and sends it across the backplane to the WAN/backhaul card and out to the Internet.
Downstream data, to the subscriber, comes from the Internet through the WAN/backhaul card, and across the backplane to the Cisco uBR10-MC5X20S/U/H cable interface line card. The Cisco uBR10-MC5X20S/U/H card processes and configures the data and sends it out through the appropriate downstream port (DS0-DS4) to be combined with the rest of the downstream signals in the headend.
The Cisco uBR10-MC5X20S/U line cards use burst receivers that report unequalized Modulation Error Ratio (MER). The Cisco uBR10-MC5X20H line cards use burst receivers that report equalized MER. Equalized MER will almost always be at least a few decibels (dB) higher than an unequalized MER measurement of the same signal under identical conditions.
The Cisco uBR10-MC5X20S cable interface line card supports downstream and upstream traffic over Data-over-Cable Service Interface Specification (DOCSIS)-based cable modem networks. The card supports downstream channels in the 70 to 860 MHz range, and upstream channels in the 5 to 42 MHz range. Each downstream port includes an onboard integrated upconverter. The Cisco uBR10-MC5X20S cable interface line card supports Annex B radio frequency (RF) data rates, channel widths, and modulation schemes and has DOCSIS MAC management and spectrum management capabilities. DOCSIS 2.0, Asynchronous Time Division Multiple Access (A-TDMA) rates are also supported.
Cisco uBR10-MC5X20U and H
The Cisco uBR10-MC5X20U/H cable interface line card supports both DOCSIS and EuroDOCSIS cable modem networks. The card supports downstream channels in the 70 to 860 MHz range, and upstream channels in the 5 to 65 MHz range. Each downstream port includes an onboard integrated upconverter. The Cisco uBR10-MC5X20U/H cable interface line card supports Annex B and Annex A radio frequency (RF) data rates, channel widths, and modulation schemes and has DOCSIS MAC management and spectrum management capabilities. DOCSIS 2.0, A-TDMA rates are also supported.
The Cisco UBR-MC20X20V cable interface line card is a 20 by 16 inch card designed specifically for the Cisco uBR10012 universal broadband router. This card transmits and receives RF signals between the subscriber and the headend over hybrid fiber-coaxial (HFC) system. It has five downstream (DS) ports and twenty upstream (US) ports. The line card supports five cable MAC domains (cable interfaces), and the 20 DS and 20 US channels are dynamically associated with any of these five MAC domains. The card has twenty US spigots and five DS spigots. Each of the US spigots supports either two-frequency stacked US channels across ten ports or a single US channel across twenty ports. Each of the DS spigots supports four-frequency stacked channels across five ports.
Note You must ensure that two DOCSIS Timing, Communication and Control (DTCC) cards are configured on the Cisco uBR10012 router before installing the Cisco UBR-MC20X20V cable interface line card.
The Cisco uBR-MC3GX60V cable interface line card is a DOCSIS 3.0 compliant line card designed specifically for the Cisco uBR10012 universal broadband router. This line card conforms to the Modular CMTS (M- CMTS) architecture and has the capacity to support up to 72 downstream (DS) and 60 upstream (US) channels.
The Cisco uBR-MC3GX60V cable interface line card has 20 US spigots for RF connectivity, which are organized into 5 groups of 4 connectors each. Each connector group supports up to 12 frequency-stacked US channels, with a default configuration of 3 US channels per RF connector.
The Cisco uBR-MC3GX60V cable interface line card has six Gigabit Ethernet (GE) interface ports organized into three pairs for DS connectivity. Each pair supports 1+1 redundancy and supports 24 DS channels in Annex B mode by default. The GE interfaces connect to an external Edge Quadrature Amplitude Modulation (EQAM) device and provide M-CMTS compliant Downstream External PHY Interface (DEPI) data.
Another unique feature of the Cisco uBR-MC3GX60V cable interface line card is the use of a front panel display (FPD) to show the licensing status information of the US and DS channels.
The single-port Gigabit Ethernet (GE) line card provides a trunk uplink to devices such as GSRs, as well as connections to content servers and Web caches. The GE line card provides the Cisco uBR10012 router with an IEEE 802.3z compliant Ethernet interface running at 1 Gbps in full duplex mode.
The port uses a Gigabit Interface Converter (GBIC) that supports Gigabit Ethernet rates on a variety of Gigabit Ethernet interface types (SX, LX/LH, ZX) which can be changed or upgraded at any time (see
Table 1-9). The Cisco uBR10012 router supports multiple GE line cards to support connectivity to multiple destinations and to provide network layer redundancy.
7.Mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required. If you use an ordinary patch cord with MMF, 1000Base-LX/LH GBICs, and a short link distance (tens of meters), this can cause transceiver saturation, resulting in a elevated bit error rate (BER). In addition, when you use the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 ft (300 m).
