Feature Support
Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. Each feature set contains a specific set of Cisco IOS features.
CautionCisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to U.S. government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of U.S. government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
The feature set tables have been removed from the Cisco IOS Release 12.1 release notes to improve the usability of the release notes documentation. The feature-to-image mapping that was provided by the feature set tables is available through Cisco Feature Navigator.
Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features unique to each software release and the features that the releases have in common.

Cisco uBR900 Series
This section contains the following sections with information that is specific to the Cisco uBR900 series cable access routers:
•
•
Introduction
The DOCSIS-based Cisco uBR900 series cable access routers—Cisco uBR924 and Cisco uBR904—give residential or small office/home office (SOHO) subscribers high-speed Internet or Intranet access. The Cisco uBR924 cable access router also supports both data traffic and packet telephone and fax services using a shared two-way cable system and IP backbone network. The Cisco uBR900 series cable access router connects computers and other customer premises devices at a subscriber site to the service provider's cable, hybrid fiber-coaxial (HFC), and IP backbone network.
The Cisco uBR900 series cable access router is based on Data-over-Cable Service Interface Specifications (DOCSIS) and interoperates with any bidirectional, DOCSIS-qualified cable modem termination system (CMTS). The Cisco uBR900 series cable access router ships from the Cisco factory with a Cisco IOS software image stored in nonvolatile Flash memory that supports DOCSIS-compliant bridging data operations. The Cisco uBR900 series cable access router functions as a cable modem (CM)—a modulator/demodulator at the subscriber site that conveys data communications on the cable television system.
Note
Based on the feature licenses your company purchased, other Cisco IOS images can be downloaded from Cisco.com. Special operating modes, based on your service offering and the practices in place for your network, can be supported for the Cisco uBR900 series router, based on the images available in Cisco IOS Release 12.1(6). The Cisco uBR900 series cable access router can also function as an advanced router, providing wide-area network (WAN) data connectivity in a variety of configurations.
Note
Cisco uBR904 Cable Access Router
The Cisco uBR904 cable access router features a single F-connector interface to the cable system, four RJ-45 (10BaseT Ethernet) hub ports, and one RJ-45 console port to connect to a laptop computer/console terminal for local Cisco IOS configuration. The Cisco uBR904 cable access router supports data-only Cisco IOS software images; available feature sets include Firewall (Phase I), Easy IP, and 56-bit IPSec.
Note
Memory Recommendations
For memory recommendations for the Cisco uBR900 series routers in Cisco IOS Release 12.1, refer to the "Memory Recommendations" section.
Headend Interoperability
IPSec Encryption Support
To use IPSec encryption, both the Cisco uBR900 series cable access router and the destination endpoint must support IPSec encryption and be configured for the same encryption policy. The endpoint is typically an IPSec gateway such as a peer router, PIX Firewall, or other device that can be configured for IPSec. (The CMTS does not need to support IPSec encryption unless it is acting as an IPSec gateway.)

Feature Support
For feature support in Cisco IOS Release 12.1, refer to the "Feature Support" section.
Limitations and Restrictions
This section describes warnings and cautions about using Cisco IOS Release 12.1software.
Access Lists 100 and 101
Access lists 100 and 101 are reserved for DOCSIS use only and should not be configured for use with IPSec encryption or any other purpose. Access lists that use any other numbers can be used without restriction.
Bridging Support
The Cisco uBR900 series cable access router interoperates with DOCSIS cable networks. Cisco IOS Release 12.1 does not support bridging traffic across a non-DOCSIS cable network.
Debug Commands
All debug commands should be used only when needed for troubleshooting and testing, and then turned off when no longer needed. Each debug display consumes system resources; turning on too many debug commands can negatively affect system performance.
DOCSIS Configuration File Size Limitation
In Cisco IOS Release 12.1(15), the DOCSIS configuration file for the Cisco uBR904 cable access router has a maximum size of 4KB.
GRE IP Tunnels Are Not Supported
Generic routing encapsulation (GRE) IP tunnels cannot be built between two Cisco uBR900 series cable access routers because GRE IP tunnels are not supported in any Cisco IOS image for the Cisco uBR900 series cable access routers. IPSec tunnels, however, are supported when using Cisco IOS images that support IPSec encryption.
Images Reduced
Because of memory limitations, Cisco IOS Release 12.1(15) supports only the Small Office image (ubr900-k1y5-mz) for the Cisco uBR904 cable access router. This image does not support the Firewall and IPSec encryption feature sets.
SNMP Network Management
Because the Cisco IOS Release 12.1 train was released before the DOCSIS specification was finalized, the Cisco uBR904 cable access router supports only the experimental DOCSIS MIBs that were used during the development of the DOCSIS specification. The Cisco uBR904 cable access router does not support the DOCSIS MIBs that were eventually finalized and approved by the Internet Activities Board (IAB).
In particular, this means that the Cisco uBR904 cable access router supports only the DOCSIS MIB attributes that start with the experimental OID of "1.3.6.1.3.83". The Cisco uBR924 cable access router does not support the IAB DOCSIS MIBs that start with the Internet Management MIB-2 docsDev OID of ".1.3.6.1.2.1.69".
Using Multiple PCs with the Cisco uBR900 Series Cable Access Router
The "MAX CPE" parameter in a Cisco uBR900 series cable access router's DOCSIS configuration file determines how many PCs (or other customer premises equipment [CPE] devices) are supported by the Cisco uBR900 series cable access router when operating in bridging mode. The default value for the "MAX CPE" parameter is 1, which means only one PC can be connected to the Cisco uBR900 series cable access router when operating in bridging mode.
The DOCSIS 1.0 specification states that a CMTS cannot age-out Media Access Control (MAC) addresses for CPE devices, so the first PC that is connected to the Cisco uBR900 series cable access router is normally the only one that the CMTS recognizes as valid. If a subscriber replaces an existing PC or changes its network interface card (NIC) to one that has a different MAC address, the CMTS will refuse to let the PC come online because this would exceed the maximum number of CPE devices specified by the "MAX CPE" parameter. A similar thing would happen if a user decides to move a PC from one Cisco uBR900 series cable access router to another.
To allow a subscriber to replace an existing PC or NIC, the following workarounds are possible:
•
•
Using the Reset Switch
The reset switch on the back panel of the Cisco uBR900 series cable access router is recessed to prevent accidental resets of the router. To depress the switch, use a blunt object, such as a pen or pencil point; do not use a sharp object, such as a knife or awl, because this could damage the switch and the router's circuitry.
Additional Notes for the Cisco uBR900 Series
This section contains important information about using Cisco IOS Release 12.1 software.
Cisco uBR904 Cable Access Router End of Life
The Cisco uBR904 cable access router is an end-of-life (EOL) product, and is no longer available for orders as of October 1999. Software images for the Cisco uBR904 router will continue to be available until November 2000 but will not contain any new feature sets. However, the software images for the Cisco uBR904 router do include the current caveat fixes.
Configuring the Cisco uBR904 Router for Routing Mode
To change the operating mode of the Cisco uBR904 cable access router from its default bridging state, complete the following procedure:
Configuring the Routing Protocol Causes a Reset of the Cable Interface
Be aware that when configuring a routing protocol on an interface, the Cisco IOS software must reset the interface to enable the change. This is normally not a problem on most interfaces, but resetting the cable interface requires the Cisco uBR904 router or Cisco uBR924 router to reinitialize, per the DOCSIS specification.
In particular, when a Cisco IOS configuration file is downloaded to a cable access router, and the file contains a command such as router rip, the cable access router will reset the cable interface when it processes that command, taking the router temporarily offline while it reacquires the cable downstream and upstream channels. This is normal and only slightly delays the cable access router's bootup sequence.
Downloading a Cisco IOS Configuration File to the Cisco uBR904 Router
The vendor-specific information field in the DOCSIS configuration file supports a vendor-defined attribute (type = 43) that lets the system administrator define the name of a Cisco IOS configuration file to download to a remote Cisco uBR904 cable access router. This requires a unique DHCP policy for the Cisco uBR904 cable access router, a unique DOCSIS configuration file to be sent by the DOCSIS process, and a unique Cisco IOS configuration filename—such as "ios.cfg" file—located in the same TFTP server directory supported by the DOCSIS process.
The Cisco uBR904 router automatically downloads the DOCSIS configuration file during initialization. If the DOCSIS configuration file contains the name of a Cisco IOS configuration file, the router automatically downloads that file and processes its Cisco IOS commands. This also automatically disables the router's console port to prevent remote configuration of the router.
Use the following procedure to enter the filename for a Cisco IOS configuration file in the router's DOCSIS configuration file:

The console port of the Cisco uBR904 cable access router is completely disabled.
Disabling the Finger Server
By default, the Cisco uBR900 series cable access router enables its onboard TCP/IP "finger" server to allow remote users to query the number and identities of any users who are logged in to the router. Unless your network operations center (NOC) requires this service, it should be disabled to prevent denial-of-service attacks that access the finger server's well-known port (TCP port 79). To disable the finger server, include the no service finger command in the Cisco IOS configuration file that the router downloads at initial power-on.
Downloading a Cisco IOS Image to the Cisco uBR904 Router
The CMTS system administrator can download an updated Cisco IOS image to a Cisco uBR904 router installed in the field by specifying the updated image filename in the router's DOCSIS configuration file. The Cisco uBR904 router automatically downloads the DOCSIS configuration file during initialization. If the software upgrade option is present in the DOCSIS configuration file and if the name of the Cisco IOS image in the DOCSIS configuration file differs from the image that is currently running on the Cisco uBR904 router, the router automatically downloads the new Cisco IOS image from the Trivial File Transfer Protocol (TFTP) server and reboots.
The image filename must be entered as the fully qualified file and path name for the file, as it exists on a TFTP server. For example, if the ubr900-k1y5-mz software image is available on the TFTP server in the 12.1 directory, enter the following as the filename:
/12.1/ubr900-k1y5-mz
Note
Supplemental and Corrected Text for the Cisco uBR904 Cable Access Router
The following is updated information to the Cisco uBR904 Cable Modem Installation and Configuration Guide.
Data transmitted to a Cisco uBR904 cable access router from the CMTS shares a 26- or 27-Mbps, 6-MHz data channel in the 88- to 860-MHz range. The Cisco uBR904 cable access router shares an upstream data rate of up to 10 Mbps on a 200-kHz-wide to 3.2-MHz-wide channel in the 5- to 42-MHz range.
Note
The Cisco uBR904 cable access router supports 64 or 256 quadrature amplitude modulation (QAM) downstream, and Quadrature Phase-Shift Keying (QPSK) or 16-QAM upstream transmission.
Table 4 lists the downstream and upstream data specifications for the Cisco uBR904 cable access router.

>15 dB @ BER<10^-8
(QPSK will work at 98% successful ping rate for SNR>13 dB. An SNR of 15 dB is needed to get almost optimal packets per minute transition.)16 QAM:
>22 dB @ BER <10^-8
(For 16 QAM, an SNR>22 dB creates a grade that is for 98% ping efficiency. To get a good packet rate, you need SNR>25 dB.)
1 These performance numbers are in laboratory-controlled conditions, against statistically pure noise sources (AWGN). Because such conditions do not exist in practice, an SNR margin of 6 dB or more is required for reliable operation. Check with your local system guidelines.
2 These measurements were done for 0 and -10 dBmV input to the CMTS, 1280 ksym/sec and 64-byte packet size with a Cisco uBR904 cable access router and laboratory-controlled conditions.
DOCSIS configuration files typically are created at the headend by using a configuration file editor of your choice. Using the FastStep utility at a subscriber site to locally configure the unit is not supported.
The DOCSIS configuration file defines the Cisco uBR904 cable access router's operating mode, such as the provisioned downstream and upstream service assignments, including assigned frequencies, data rates, modulation schemes, class of service (CoS), type of services to support, and other parameters.
Note
The Cisco uBR904 cable access router supports the following service classes:
•
This service class assigns a primary Service ID (SID) for the unit. In addition to being used as a data SID, the router uses this SID for all MAC message exchanges with the CMTS. Any Simple Network Management Protocol (SNMP) management traffic from the network to the Cisco uBR904 cable access router also uses this SID.
While this class is strictly "best effort," you can prioritize data traffic within this class into eight different priority levels.

Supplemental and Corrected Text for the Online Feature Module
For the Cisco uBR904 Cable Access Router
Troubleshooting Tips for the Cisco uBR904 Cable Modem, page 11, indicates:
"Some CATV systems use alternative frequency plans such as the IRC (Incrementally Related Carrier) and HRC (Harmonically Related Carrier) plans. Most of the IRC channel slots overlap the EIA plan. The HRC plan is not supported by Cisco's cable modems since so few cable plants are using this plan."
The correction should read:
"For the Cisco uBR904 cable access router, both the Incrementally Related Carrier (IRC) and Harmonically Related Carrier (HRC) plans are supported. Most of the IRC channel slots overlap the EIA plan.
"The list of downstream search bands added for HRC have appropriate center frequencies and step values for an HRC channel plan. The expanded search band list might increase the time required by the Cisco uBR904 cable access router to acquire the downstream signal on the HRC channel plan, which can add to the total time for complete registration of the Cisco uBR904 cable access router the first time it is added to the cable system."
Supported MIBs
The Cisco uBR900 series cable access router supports the following categories of Management Information Bases (MIBs):
•
•
•
•
•
•
•
•
Cable Device MIBs
For the Cisco uBR900 series cable access router, the Cable Device MIB is supported. The Cable Device MIB is for DOCSIS-compliant cable modems and CMTS. The Cable Device MIB records statistics related to the configuration and status of the cable modem. Statistics include an events log and device status. The following list details the components of the Cable Device MIB:
•
•
•
•
•
•
The Cable Device MIB is very similar to the RFI MIB in that both allow access to statistics. However, the Cable Device MIB reports statistics on the cable modem, while the RFI MIB reports statistics on the radio frequency transmissions over the cable television line.
Cisco Standard MIBs
For the Cisco uBR900 series cable access router, the Cisco Standard MIBs are supported. The Cisco Standard MIBs consist of the following components:
•
•
•
•
•
•
Note
Radio Frequency Interface MIBs
For the Cisco uBR900 series cable access router, the Radio Frequency Interface (RFI) MIB is supported. The RFI MIB module is for DOCSIS-compliant radio frequency interfaces in cable modems and CMTS. On the cable modem, RFI MIB entries provide:
•
•
•
•
•
The RFI MIB includes tables describing both the CMTS and the cable modem side of the cable interface. All cable modem tables are implemented.
With IPSec, data can be transmitted across a public network without fear of observation, modification, or spoofing. This enables applications such as VPNs, extranets, and remote user access.
IPSec services are similar to those provided by Cisco Encryption Technology, a proprietary Cisco security solution. However, IPSec provides a more robust security solution, and is standards based.
SGCP MIBs (Cisco uBR924 Only)
The Simple Gateway Control Protocol (SGCP) Management Information Bases (MIBs) are supported only on the Cisco uBR924 cable access router. The SGCP MIBs support configuration, performance, and fault management of the SGCP interface. The SGCP MIBs components are as follows:
•
•
•
•
•
•
•
•
•
•
•
•
Cable-Specific MIBs
Table 5 shows the cable-specific MIBs that are supported on the Cisco uBR900 series cable access router. This table also provides a brief description of each MIBs contents and the Cisco IOS software release in which the MIB was initially functional—earlier releases might have had unsupported prototype versions of the MIB; later releases might have added new attributes and functionality.

The Cisco uBR900 series cable access router can also function as an advanced router, providing wide-area network (WAN) data connectivity in a variety of configurations.
Note
Cisco uBR924 Cable Access Router
The Cisco uBR924 cable access router features a single F-connector interface to the cable system, four RJ-45 (10BaseT Ethernet) hub ports, two RJ-11 Foreign Exchange Station (FXS) voice ports, one RJ-11 port for an optional backup analog telephone line connection, and one RJ-45 console port to connect to a laptop computer/console terminal for local Cisco IOS configuration. The Cisco uBR924 cable access router supports voice and data Cisco IOS software images; available feature sets include Cisco IOS Firewall, Easy IP, Layer 2 Tunneling Protocol (L2TP), and 56-bit and 168-bit IP security (IPSec) encryption.
Memory Recommendations
For memory recommendations for the Cisco uBR920 series routers in Cisco IOS Release 12.1, refer to the "Memory Recommendations" section.
Headend Interoperability
Cisco Cable Clock Card Support
When using Cisco IOS Release 12.1(1) or greater, the Cisco uBR924 cable access router automatically supports the Cisco Cable Clock Card feature for voice traffic when the CMTS is a Cisco uBR7246 VXR universal broadband router with the Cisco Cable Clock Card feature. The Cisco uBR904 cable access router does not support this feature.
IPSec Encryption Support
To use IPSec encryption, both the Cisco uBR900 series cable access router and the destination endpoint must support IPSec encryption and be configured for the same encryption policy. The endpoint is typically an IPSec gateway such as a peer router, PIX Firewall, or other device that can be configured for IPSec. (The CMTS does not need to support IPSec encryption unless it is acting as an IPSec gateway.)
Note
Voice Protocol Support (Cisco uBR924 Router Only)
When using a Cisco IOS Release 12.1 image, the Cisco uBR924 cable access router can packetize and transport voice in compliance with the H.323 protocol. H.323v2 is integrated in Cisco gatekeeper/gateway products, such as the Cisco 2600 series and Cisco 3600 series, using Cisco IOS Release 12.0(5)T or higher images. The gatekeeper must be running Cisco IOS Release 12.0(5)T or higher in order to support registration of the full E.164 address for each Cisco uBR924 cable access router voice port.
The Cisco uBR924 cable access router also supports the Simple Gateway Control Protocol (SGCP) when using Cisco IOS Release 12.1(6) images. SGCP is an alternative to the H.323 protocol that provides signaling and feature negotiation using a remote call agent (CA). SGCP eliminates the need for a dial-plan mapper. It also eliminates the need for static configuration on the router to map IP addresses to telephone numbers because this function is provided by the remote call agent.

For feature support in Cisco IOS Release 12.1, refer to the "Feature Support" section.
Limitations and Restrictions
This section describes warnings and cautions about using Cisco IOS Release 12.1 software.
Access Lists 100 and 101
Access lists 100 and 101 are reserved for DOCSIS use only and should not be configured for use with IPSec encryption or any other purpose. Access lists that use any other numbers can be used without restriction.
Bridging Support
The Cisco uBR900 series cable access router interoperates with DOCSIS cable networks. Cisco IOS Release 12.1 does not support bridging traffic across a non-DOCSIS cable network.
Debug Commands
All debug commands should be used only when needed for troubleshooting and testing, and then turned off when no longer needed. Each debug display consumes system resources; turning on too many debug commands can negatively affect system performance.
GRE IP Tunnels Are Not Supported
Generic routing encapsulation (GRE) IP tunnels cannot be built between two Cisco uBR900 series cable access routers because GRE IP tunnels are not supported in any Cisco IOS image for the Cisco uBR900 series cable access routers. IPSec tunnels, however, are supported when using Cisco IOS images that support IPSec encryption.
Using Multiple PCs with the Cisco uBR900 Series Cable Access Router
The "MAX CPE" parameter in a Cisco uBR900 series cable access router's DOCSIS configuration file determines how many PCs (or other customer premises equipment [CPE] devices) are supported by the Cisco uBR900 series cable access router when operating in bridging mode. The default value for the "MAX CPE" parameter is 1, which means only one PC can be connected to the Cisco uBR900 series cable access router when operating in bridging mode.
The DOCSIS 1.0 specification states that a CMTS cannot age-out Media Access Control (MAC) addresses for CPE devices, so the first PC that is connected to the Cisco uBR900 series cable access router is normally the only one that the CMTS recognizes as valid. If a subscriber replaces an existing PC or changes its network interface card (NIC) to one that has a different MAC address, the CMTS will refuse to let the PC come online because this would exceed the maximum number of CPE devices specified by the "MAX CPE" parameter. A similar thing would happen if a user decides to move a PC from one Cisco uBR900 series cable access router to another.
To allow a subscriber to replace an existing PC or NIC, the following workarounds are possible:
•
•
Using the Reset Switch
The reset switch on the back panel of the Cisco uBR900 series cable access router is recessed to prevent accidental resets of the router. To depress the switch, use a blunt object, such as a pen or pencil point; do not use a sharp object, such as a knife or awl, because this could damage the switch and the router's circuitry.
Additional Notes for the Cisco uBR900 Series
This section contains important information about using Cisco IOS Release 12.1 software.
Configuring the Routing Protocol Causes a Reset of the Cable Interface
Be aware that when configuring a routing protocol on an interface, the Cisco IOS software must reset the interface to enable the change. This is normally not a problem on most interfaces, but resetting the cable interface requires the Cisco uBR904 router or Cisco uBR924 router to reinitialize, per the DOCSIS specification.
In particular, when a Cisco IOS configuration file is downloaded to a cable access router, and the file contains a command such as router rip, the cable access router will reset the cable interface when it processes that command, taking the router temporarily offline while it reacquires the cable downstream and upstream channels. This is normal and only slightly delays the cable access router's bootup sequence.
Downloading a Cisco IOS Configuration File to the Cisco uBR904 Router
The vendor-specific information field in the DOCSIS configuration file supports a vendor-defined attribute (type = 43) that lets the system administrator define the name of a Cisco IOS configuration file to download to a remote Cisco uBR904 cable access router. This requires a unique DHCP policy for the Cisco uBR904 cable access router, a unique DOCSIS configuration file to be sent by the DOCSIS process, and a unique Cisco IOS configuration filename—such as "ios.cfg" file—located in the same TFTP server directory supported by the DOCSIS process.
The Cisco uBR904 router automatically downloads the DOCSIS configuration file during initialization. If the DOCSIS configuration file contains the name of a Cisco IOS configuration file, the router automatically downloads that file and processes its Cisco IOS commands. This also automatically disables the router's console port to prevent remote configuration of the router.
Use the following procedure to enter the filename for a Cisco IOS configuration file in the router's DOCSIS configuration file:

The console port of the Cisco uBR904 cable access router is completely disabled.
Disabling the Finger Server
By default, the Cisco uBR900 series cable access router enables its onboard TCP/IP "finger" server to allow remote users to query the number and identities of any users who are logged in to the router. Unless your network operations center (NOC) requires this service, it should be disabled to prevent denial-of-service attacks that access the finger server's well-known port (TCP port 79). To disable the finger server, include the no service finger command in the Cisco IOS configuration file that the router downloads at initial power-on.
Downloading a Cisco IOS Image to the Cisco uBR904 Router
The CMTS system administrator can download an updated Cisco IOS image to a Cisco uBR904 router installed in the field by specifying the updated image filename in the router's DOCSIS configuration file. The Cisco uBR904 router automatically downloads the DOCSIS configuration file during initialization. If the software upgrade option is present in the DOCSIS configuration file and if the name of the Cisco IOS image in the DOCSIS configuration file differs from the image that is currently running on the Cisco uBR904 router, the router automatically downloads the new Cisco IOS image from the Trivial File Transfer Protocol (TFTP) server and reboots.
The image filename must be entered as the fully qualified file and path name for the file, as it exists on a TFTP server. For example, if the ubr900-k1y5-mz software image is available on the TFTP server in the 12.1 directory, enter the following as the filename:
/12.1/ubr900-k1y5-mz
Note
PPP IPCP Enhancements
The PPP IPCP command, which supplies Domain Name System (DNS) or Windows Internet Naming Service (WINS) addresses during IP Control Protocol (IPCP) negotiation, has been enhanced with the reject and accept keywords. These keywords allow enabling or disabling support for the Microsoft IPCP extensions defined by RFC 1877.
Supplemental and Corrected Text for the Cisco uBR904 Cable Access Router
The following is updated information to the Cisco uBR904 Cable Modem Installation and Configuration Guide.
Data transmitted to a Cisco uBR904 cable access router from the CMTS shares a 26- or 27-Mbps, 6-MHz data channel in the 88- to 860-MHz range. The Cisco uBR904 cable access router shares an upstream data rate of up to 10 Mbps on a 200-kHz-wide to 3.2-MHz-wide channel in the 5- to 42-MHz range.
Note
The Cisco uBR904 cable access router supports 64 or 256 quadrature amplitude modulation (QAM) downstream, and Quadrature Phase-Shift Keying (QPSK) or 16-QAM upstream transmission.
Table 6 lists the downstream and upstream data specifications for the Cisco uBR904 cable access router.

Signal-to-Noise Ratio (SNR)1
64 QAM:
>23.5 dB @ BER<10^8256 QAM*:
>30 dB @ BER <10^-8
(For input levels between +15 and -8 dBmV, SNR must be greater than 30 dB. For input levels between -8 and -15 dBmV, SNR must be greater than 33 dB.)QPSK:2
>15 dB @ BER<10^-8
(QPSK will work at 98% successful ping rate for SNR>13 dB. An SNR of 15 dB is needed to get almost optimal packets per minute transition.)16 QAM:
>22 dB @ BER <10^-8
(For 16 QAM, an SNR>22 dB creates a grade that is for 98% ping efficiency. To get a good packet rate, you need SNR>25 dB.)
1 These performance numbers are in laboratory-controlled conditions, against statistically pure noise sources (AWGN). Because such conditions do not exist in practice, an SNR margin of 6 dB or more is required for reliable operation. Check with your local system guidelines.
2 These measurements were done for 0 and -10 dBmV input to the CMTS, 1280 ksym/sec and 64-byte packet size with a Cisco uBR904 cable access router and laboratory-controlled conditions.
DOCSIS configuration files typically are created at the headend by using a configuration file editor of your choice. Using the FastStep utility at a subscriber site to locally configure the unit is not supported.
The DOCSIS configuration file defines the Cisco uBR904 cable access router's operating mode, such as the provisioned downstream and upstream service assignments, including assigned frequencies, data rates, modulation schemes, class of service (CoS), type of services to support, and other parameters.
Note
The Cisco uBR904 cable access router supports the following service classes:
•
This service class assigns a primary Service ID (SID) for the unit. In addition to being used as a data SID, the router uses this SID for all MAC message exchanges with the CMTS. Any Simple Network Management Protocol (SNMP) management traffic from the network to the Cisco uBR904 cable access router also uses this SID.
While this class is strictly "best effort," you can prioritize data traffic within this class into eight different priority levels.

Supplemental and Corrected Text for the Online Feature Module
For the Cisco uBR924 Cable Access Router
Troubleshooting Tips for the Cisco uBR924 Cable Access Router, page 15, indicates:
"Some CATV systems use alternative frequency plans such as the IRC (Incrementally Related Carrier) and HRC (Harmonically Related Carrier) plans. Most of the IRC channel slots overlap the EIA plan. The HRC plan is not supported by Cisco's cable access routers since so few cable plants are using this plan."
The correction should read:
"For the Cisco uBR924 cable access router, both the Incrementally Related Carrier (IRC) and Harmonically Related Carrier (HRC) plans are supported. Most of the IRC channel slots overlap the EIA plan.
"The list of downstream search bands added for HRC have appropriate center frequencies and step values for an HRC channel plan. The expanded search band list might increase the time required by the Cisco uBR924 cable access router to acquire the downstream signal on the HRC channel plan, which can add to the total time for complete registration of the modem the first time it is added to the cable system."
Note
Supported MIBs
The Cisco uBR900 series cable access router supports the following categories of Management Information Bases (MIBs):
•
•
•
•
•
•
•
•
Cable Device MIBs
For the Cisco uBR900 series cable access router, the Cable Device MIB is supported. The Cable Device MIB is for DOCSIS-compliant cable modems and CMTS. The Cable Device MIB records statistics related to the configuration and status of the cable modem. Statistics include an events log and device status. The following list details the components of the Cable Device MIB:
•
•
•
•
•
•
The Cable Device MIB is very similar to the RFI MIB in that both allow access to statistics. However, the Cable Device MIB reports statistics on the cable modem, while the RFI MIB reports statistics on the radio frequency transmissions over the cable television line.
Cisco Standard MIBs
For the Cisco uBR900 series cable access router, the Cisco Standard MIBs are supported. The Cisco Standard MIBs consist of the following components:
•
•
•
•
•
•
Note
Cisco Voice MIBs
The Cisco Voice MIBs are supported only on the Cisco uBR924 cable access router. The Cisco Voice MIBs consist of the following components:
•
•
•
•
•
•
Radio Frequency Interface MIBs
For the Cisco uBR900 series cable access router, the Radio Frequency Interface (RFI) MIB is supported. The RFI MIB module is for DOCSIS-compliant radio frequency interfaces in cable modems and CMTS. On the cable modem, RFI MIB entries provide:
•
•
•
•
•
The RFI MIB includes tables describing both the CMTS and the cable modem side of the cable interface. All cable modem tables are implemented.
With IPSec, data can be transmitted across a public network without fear of observation, modification, or spoofing. This enables applications such as VPNs, extranets, and remote user access.
IPSec services are similar to those provided by Cisco Encryption Technology, a proprietary Cisco security solution. However, IPSec provides a more robust security solution, and is standards based.
SGCP MIBs
The Simple Gateway Control Protocol (SGCP) Management Information Bases (MIBs) are supported only on the Cisco uBR924 cable access router. The SGCP MIBs support configuration, performance, and fault management of the SGCP interface. The SGCP MIBs components are as follows:
•
•
•
•
•
•
•
•
•
•
•
•
Cable-Specific MIBs
Table 7 shows the cable-specific MIBs that are supported on the Cisco uBR900 series cable access router. This table also provides a brief description of each MIBs contents and the Cisco IOS software release in which the MIB was initially functional—earlier releases might have had unsupported prototype versions of the MIB; later releases might have added new attributes and functionality.

Cisco MC3810 Multiservice Access Concentrator
This section contains the following sections with information that is specific to the Cisco MC3810 multiservice access concentrator:
•
Introduction
The Cisco MC3810 multiservice access concentrator is fully supported by Cisco IOS software for multiprotocol routing, bridging, and Systems Network Architecture (SNA). As part of an enterprise backbone or as customer premises equipment (CPE) to serve provider-managed network services, the Cisco MC3810 reduces operating costs and complexity and increases network throughput and performance.
The Cisco MC3810 provides a complete file system for software images, message files, and reports. The standard Flash memory size is 8 MB, and a 16-MB upgrade option is available. The 16-MB version can hold two code images simultaneously for fail-safe upgrades.
Management and configuration of the Cisco MC3810 should be familiar to the Cisco IOS user and compatible with existing management systems. As such, it provides a superset of the Cisco command-line interface (CLI). The Cisco MC3810 can be managed by standard Cisco management platforms and facilities such as CiscoView and the native remote log-in facilities provided by Telnet and rlogin. Three types of configuration interfaces are provided:
•
•
•
The HTTP-based interface allows configuration from any web browser such as Netscape Navigator or Microsoft Explorer. The SNMP MIB allows management of the Cisco MC3810 from SNMP managers (for example, HP OpenView).
Memory Recommendations
For memory recommendations for the Cisco MC3810 multiservice access concentrator in Cisco IOS Release 12.1, refer to the "Memory Recommendations" section.

Additional Notes for the Cisco MC3810
This section contains important information about the use of your Cisco IOS Release 12.1(6) software.
Using the Cisco MC3810 with QSIG or BRI
Serial port 1 is restricted to DCE operation when the following occurs:
•
•
•
Using the Cisco MC3810 with the PSTN
This section includes important notes regarding use of the Cisco MC3810 with the Public Switched Telephone Network (PSTN).
•
Exercise care when connecting switched voice ports on the Cisco MC3810 directly to the PSTN because improper configurations can expose a corporate network to telephone fraud.
•
The Cisco MC3810 can connect a user from the PSTN directly to the corporate wide-area telephone network. You can configure the Cisco MC3810 as a phone switch that can switch a user to any location in that network, even to remote locations that are connected again to another PSTN. However, the Cisco MC3810 does not provide any mechanism to restrict users from calling after they are connected. Without proper network design, this condition could result in the unauthorized use of the corporate network for making calls at the corporation's expense. To prevent this from occurring, Cisco does not recommend connecting a switched voice interface on the Cisco MC3810 directly to the PSTN. Instead, it should be connected to a PBX that implements a security scheme that prevents unauthorized use.
•
The same opportunity for illicit use does not exist for non-switched call types such as pass-through connections, although the possibility for fraud does exist at the direct contact point. Pass-through calls create a path to only a single location specified by the network administrator. For example, a pass-through connection might be used to pass a trunk from a PBX to the PSTN. In this case, the trunk on the PBX always passes straight through the Cisco MC3810 to the PSTN. As a result, the necessary security is provided by the PBX.

Cisco AS5300 Universal Access Server
This section contains the following sections with information that is specific to the Cisco AS5300 universal access server:
•
Introduction
The Cisco AS5300 is a versatile data communications platform that performs two functions in a single modular chassis depending on the installed feature cards and IOS images:
•
•
The remote access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections and medium to large sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy migration path from analog dial access services to digital dial access services.
The Cisco AS5300/Voice Gateway is a versatile data communications platform that provides the functions of an access server, router, and digital modem(s) in a single modular chassis. The Cisco AS5300 includes three feature card slots: one holds a T1/E1/PRI feature card, and the other two support modem feature cards or voice digital signal processor (DSP) feature cards. When equipped with modem cards, the Cisco AS5300 serves as a remote access concentrator for dial-up (modem or ISDN) Internet access. When equipped with voice feature cards and Voice IOS, the Cisco AS5300/Voice Gateway serves as a voice (VoIP) gateway. By using one slot for modems and the other for voice DSPs, the Cisco AS5300 can serve in both capacities. Modem, voice, or fax calls are routed to the appropriate cards/resources via Dialed Number Identification Service (DNIS).
For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.1(6), see "New and Changed Information" section and "Related Documentation" section.

Cisco AS5800 Universal Access Server
This section contains the following sections with information that is specific to the Cisco AS5800 universal access server:
•
Introduction
The Cisco AS5800 access server is a high-density, Integrated Services Digital Network (ISDN), and modem Wide Area Network (WAN) aggregation systems that provide digital and analog call termination. They are intended to be used as a service provider dial point-of-presence (POP) or centralized enterprise dial gateway. The Cisco AS5800 consists of a dial shelf and one or two router shelves:
•
ISDN calls are terminated onboard the trunk card on High-Level Data Link Control (HDLC) controllers. The E1 trunk, T1 trunk, and the CT3 trunk cards include channel service units (CSUs) and have either 12 E1 ports, 12 T1 ports, or 28 T1 ports (within the CT3 trunk) that can operate as Primary Rate Interfaces (PRIs), inter-machine trunks (IMTs), or channelized interfaces in any combination.
Note
•
Note
The AC-input power shelf is an optional component of the Cisco AS5800 and is used to convert AC-input power into DC-output power for the DC-powered Cisco 5814 dial shelf. The AC-input power shelf contains two AC-input power supplies.
The AC-input to DC-output connection supplies -48V DC-output power to the dial shelf power entry modules (PEMs). The PEMs receive the -48V and transmit power to the filter module. Power flows through the filter module to the backplane, where it is distributed to the dial shelf controller card(s) and feature cards.
The AC-input power shelf includes two 2,000 W, AC-input power supplies that plug into a common power backplane in the AC-input power shelf. A single AC-input power supply is capable of powering a fully configured Cisco 5814 dial shelf. The second power supply provides full redundancy.
Cisco AS5800/Voice Gateway
The Cisco AS5800/Voice Gateway enables highly scalable deployment of toll-quality voice and fax services over data networks. Enhanced with Cisco's IOS software and Service Node (SN) capabilities, the Cisco AS5800 supports features such as prepaid and postpaid calling card, 800 call redirect, voice activated dialing, and voice and fax mail.
The Cisco AS5800 is specifically designed to meet the demands of large service providers such as Post, Telephone, and Telegraphs (PTTs), regional bell operating companies (RBOCs), inter-exchange carriers (IXCs), and large Internet telephony service providers (ITSPs). The physical architecture of the Cisco AS5800 product enhances reliability, availability, and serviceability. Critical features to dial POP administrators include minimizing downtime, service costs, and time to deployment.
The Cisco AS5800 supports up to 2016 ports in a single system, thus offering the highest concentration of VoIP Digital Signal Processors (DSPs) available in a single voice gateway. The Cisco AS5800 offers breakthrough voice quality, density, and scalability, while continuing to provide the rich set of access, VoIP, and QoS services that are part of Cisco IOS software.
For more information on the Cisco AS5800, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (DOC-5800-SICG) or the Cisco AS5800 Universal Access Server Hardware Installation Guide (DOC-5800-HICG) that shipped with your system.

Cisco uBR7200 Universal Broadband Router
This section contains the following sections with information that is specific to the Cisco uBR7200 universal broadband router:
•
Introduction
The Cisco uBR7200 Series Universal Broadband Routers—the Cisco uBR7223, the Cisco uBR7246, and the Cisco uBR7246 VXR—are based on the Data-over-Cable Service Interface Specification (DOCSIS) standards. Each is designed to be installed at a cable operator's headend facility or distribution hub and to function as the cable modem termination system (CMTS) for subscriber-end devices such as Cisco uBR904 and Cisco uBR924 cable access routers, and other DOCSIS-based cable modems (CMs) and set-top boxes (STBs).
Cisco uBR7200 Series Universal Broadband Routers allow two-way transmission of digital data and Voice over IP (VoIP) traffic over a hybrid fiber-coaxial (HFC) network. For cable plants not fully upgraded to support two-way cable transmission, the routers support DOCSIS-compliant telco return, where the cable modem's return path to the CMTS uses a dial-up telephone line connection instead of an upstream channel over the coaxial cable. The telco-return delivery mechanism enables cable operators to accelerate deployment of high-speed data services before the cable systems are upgraded to two-way plants.
These routers support Internet Protocol (IP) routing with a wide variety of protocols and combinations of Ethernet, Fast Ethernet, Gigabit Ethernet, serial, High-Speed Serial Interface (17), Packet over SONET (POS) OC-3 and OC-12c, and Asynchronous Transfer Mode (ATM) media. Additional protocols and media might be added as they become available for the Cisco uBR7200 series routers.
Cisco IOS Release 12.1 supports the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223.

Limitations and Restrictions
Cisco IOS Release 12.1(6) for the Cisco uBR7200 Series Universal Broadband Routers contains the following limitations and restrictions. Unless otherwise indicated, these limitations and restrictions apply to all previous software releases as well.
Port Adapter Support for Cisco uBR7246 VXR
The port adapters shown in Table 26Table 26 must be at the indicated hardware revision levels to be used in the Cisco uBR7246 VXR router. If an earlier revision level of one of these port adapters is installed in a Cisco uBR7246 VXR router, the port adapter is disabled and the following error message appears:
%PA-3-REVNOTSUPPORTED: PA in slot x (xxxx) requires base h/w revision of (x.xx) for this chassis

Additional Notes for Cisco uBR7200 Series
Cable Bundling
To reduce the number of subnets consumed per Cisco CMTS, cable interface bundling is used. Multiple cable interfaces can share a single IP subnet. An IP subnet is required for each bundle. You can bundle all cable interfaces on a Cisco CMTS into a single bundle.
Note
Using the CLI, first configure a master interface for a cable interface bundle. The master interface has an IP address assigned and is visible for IP routing functionality. After you configure the master interface, add additional cable interfaces to the same interface bundle. Those interfaces must not have an IP address assigned. You can also configure multiple bundle interfaces.
Use the following commands to configure and view cable interface bundles:
[no] cable bundle n master
show cable bundle
Up to four interface bundles can be configured. In each bundle, specify exactly one interface as the master interface, using the "master" keyword. In the case of a subinterface over a cable bundle, `x' is the interface number of the bundle master [1]. The subinterface number starts from 1.
Caution
When bundling cable interfaces, only the interface configured to be the bundle master is allowed to have subinterfaces. An interface that has subinterface(s) defined over it will not be allowed to be part of a bundle.
MIB objects on cable interface bundles are not supported as of the date of this publication.
For more information on cable bundling, refer to the chapter Understanding System Operations of the Cisco uBR7200 Series Software Configuration Guide.
Supported MIBs
The Cisco uBR7200 Series Universal Broadband Routers support the following categories of MIBs:
•
•
•
•
The cable-specific MIBs and deprecated MIBs are described in the following sections. For information on the SNMP standard MIBs and Cisco's platform and network-layer enterprise MIBs, refer to Cisco's MIB website at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
Cable-Specific MIBs
Table 27 shows the cable-specific MIBs that are supported on the Cisco uBR7200 Series Universal Broadband Routers. The table also provides a brief description of each MIBs contents and the Cisco IOS release in which the MIB was initially functional—earlier releases might have had unsupported prototype versions of the MIB; later releases might have added new attributes and functionality. Because of interdependencies, the MIBs must be loaded in the order given in the table.
