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.


Caution Cisco 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 12.2 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 Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/cfn

Additional Notes for the Cisco Voice Gateway 200

This section describes additional notes for the Cisco Voice Gateway 200 for Cisco IOS Release 12.2.

Handling Incoming Caller ID Digits on an E&M Port

When using an H.323 T1-CAS E&M port on the Cisco VG200, incoming caller ID digits may not be processed correctly by Cisco IP Interactive Voice Response (IVR) applications, such as Cisco IP Auto-Attendant.

Depending on the T1-CAS line provisioning, incoming dialed number information service (DNIS) digits received by the Cisco VG200 after its first wink to the Central Office (CO) are treated as user-entered digits and are sent to the remote endpoint as out-of-band dual tone multifrequency (DTMF) digits. If the remote endpoint is a Cisco IP IVR application, the out-of-band digits will be interpreted as a user entry and will change the application response. There are two ways to handle this situation:

Request the T1 service provider to stop sending DNIS digits.

Configure an IP phone with the same directory number as the incoming DNIS, and then modify the "forward all" selection for this phone so that it sends the incoming call to the desired destination.

Managing Input Gain for Cisco IP Voice Applications

When using the FXO ports on a Cisco VG200, set the input gain greater than 10 to achieve adequate audio quality for use with Cisco IP voice applications or the Cisco IP Phone 7960. Enter the following series of commands from the Cisco IOS command line to set the correct value for input gain:

vg200# configure terminal
vg200(config)# voice-port x/x/x input gain <value> 

Permitted entries for <value> are from -6 to 14. Gain values higher than 12 may cause DTMF recognition difficulties.

Enabling DTMF Relay with MGCP

Make sure that you use the MGCP configuration command for enabling DTMF relay. If this command is not configured, DTMF tones will be not be regenerated correctly on the remote endpoint. The required command is as follows:

router(config)# mgcp dtmf-relay codec all mode out-of-band

For further information about configuring MGCP, refer to the Software Configuration Guide for the Cisco VG200.

Cisco 801-804 Routers

The Cisco 801-804 routers provide the following key hardware features:

Cisco 802 and Cisco 804 routers have an integrated NT-1, which eliminates the need for an external NT-1 in North America.

Cisco 803 and Cisco 804 routers provide connection to analog telephones, fax machines, or modems, which are connected to telephone services through an ISDN line.

Flash memory: Default is 8 MB, expandable to 12 MB. (4-MB Flash soldered to the motherboard.)


Note To add additional Flash memory to the Cisco 801-804, remove the existing Flash card and install a new one.


Dynamic RAM: Default is 4 MB, expandable to 12 MB. (4-MB Dynamic RAM soldered to the motherboard.)

ISDN B-channel LEDs are a different color from the other LEDs, which make them easy to distinguish.

Color-coded ports and cable reduce the chance of cabling errors.

Routers can be stacked or mounted on a wall.

Cisco 805 Router

The Cisco 805 router connects small professional offices over serial lines to corporate networks and to the Internet, and provides the following key features:

One serial WAN interface that delivers up to 512 kbps for synchronous serial connections (Frame Relay, leased lines, and X.25) or up to 115 kbps for asynchronous dial-up.

One Ethernet LAN interface.

Flash memory: Default is 4 MB, expandable to 12 MB. (4-MB Flash soldered to the motherboard.)

Dynamic RAM: Default is 8 MB, expandable to 16 MB. (8-MB Dynamic RAM soldered to the motherboard.)

Color-coded ports and cable reduce the chance of cabling errors.

Routers can be stacked.

For feature support in Cisco IOS Release 12.2, refer to the "Feature Support" section.

Additional Notes for the Cisco 800 Series

caller-id Command

When using the caller-id command, which appears under "dial-peer" in the configuration commands, the default setting is "off" for Japan and "on" for the U.S. This command was introduced in Cisco IOS Release 12.1(2)XF.

DHCP Client Support

To configure the router for Dynamic Host Configuration Protocol (DHCP) client support, perform the following steps:


Step 1 Configure the Bridge Group Virtual Interface (BVI) interface by entering the ip address dhcp client-id ethernet 0 command.

Specifying the value client-id ethernet0 causes the MAC address of the Ethernet interface to be used as the client ID when the DHCP request is sent. Otherwise, the MAC address of the BVI interface is used as the client ID.

Step 2 Configure Network Address Translation (NAT).

a. Configure the BVI interface by entering the nat outside command.

b. Configure the Ethernet interface by entering the nat inside command.

c. Create an access list under NAT by entering the access-list 1 permit ip-address command to match all Ethernet IP addresses.

d. Configure the source list under NAT by entering the command ip nat inside source list 1 interface BVI 1 overload.

The following is a sample configuration:

Downloading Images

Delete files in the router Flash memory before attempting to download new images.


Caution Use the delete command, not the erase command, to free up space. Entering the erase command removes all files, including the configuration.

Flash Memory

Cisco 800 series routers use 4 MB of Flash memory for storing internal information such as the ROM monitor. Only the remainder of the Flash memory is available for storing Cisco IOS images and is displayed by using the show flash command. For example, if the router reports 8 MB of Flash, the actual amount of onboard Flash memory is 12 MB, even though only 8 MB are displayed and available for Cisco IOS image storage.

Multilink PPP and Interleaving

Multilink PPP fragments large data packets to allow small voice packets to be interleaved between them. However, apart from FIFO queuing, no other kind of output queuing mechanisms are currently supported with PPP over ATM. Consequently, when multilink PPP is configured on the Cisco 800 series routers, large packets are fragmented, but small voice packets are not interleaved between them.

NAT Support for H.323 Signaling

NAT does not support alerting H.225 messages; therefore, NAT communication cannot be established between router end points. NAT support for H.323 signaling is limited to the application NetMeeting.

PPP over AAL5SNAP Encapsulation Support

PPP over AAL5SNAP encapsulation is currently not supported, although the context sensitive help mentions that it can be configured.

Cisco 800 Series Router Clock—CSCdp09409

To run IP Security (IPSec) successfully, the Cisco 800 series router clock needs to be set accurately. Cisco 800 series router clocks are set and maintained using Simple Network Time Protocol (SNTP). For best results, set up a Network Time Protocol (NTP) server to periodically send time information messages to Cisco 800 series routers. See the SNTP configuration and command reference documentation for configuration instructions. If you do not have an NTP server, you must reset the Cisco 800 series router clock using the clock set command each time you restart the router.

Dial Peer Limitation

The isdn answer1 and isdn answer2 commands determine which called telephone numbers, for example, 555-1111 and 555-2222, a Cisco 800 series router can answer. Using these commands limits a router to using the two dial peers that contain the telephone numbers 555-1111 and 555-2222. (When not using these commands, a router can use up to six dial peers.)

A sample scenario in which the isdn answer1 and isdn answer2 commands are used is when a Cisco 801 or Cisco 803 router is connected with other ISDN devices to an ISDN S-bus.

Excessive ISDN Line Activation

The following protocols send updates that can cause an ISDN line to be activated excessively, thereby increasing your monthly ISDN line cost:

IP

User Datagram Protocol (UDP)

Internetwork Packet Exchange (IPX)

Cisco Discovery Protocol (CDP)

Simple Network Time Protocol (SNTP)

For information on preventing this situation, refer to the Cisco 800 Series Routers Software Configuration Guide. This guide contains information on setting up extended access lists to prevent IP, UDP, IPX, and SNTP updates from activating the ISDN line. For CDP, make certain that you enter the no cdp enable command to disable CDP.

Hanging During Boot

If an illegal console configuration is issued to the router, the console will fail the POST test during boot and cause the router to hang. There is no way to recover a unit in this state except by pulling the soldered boot Flash and reburning the boot ROM.

This problem has been resolved in TinyROM version 1.0(3), a downloadable ROM upgrade available from Cisco.com. Please contact Cisco to upgrade to this version or later, and prevent this problem from occurring.

Phone Mate Answering Machine Model 9200

A Phone Mate answering machine model 9200 failed to recognize the ringing signal sent by AMD R79 ringing SLIC. This was confirmed by testing against Phone Mate model 3750 and newer model 9300.

B Channel Activation

When a call comes in, a B channel is activated. If the amount of traffic on the B channel exceeds a threshold, the other B channel is activated. If the amount of traffic falls below the threshold, one of the B channels is deactivated. The B channel that is initially activated when the call comes in is not necessarily B1, nor is the B channel that is deactivated when the traffic level lessens necessarily B2.

Additional Notes for the Cisco uBR924 Cable Access Router

Introduction

The DOCSIS-based Cisco uBR924 cable access router gives residential or small office/home office (SOHO) subscribers high-speed Internet or intranet access. The Cisco uBR924 cable access router supports both data traffic and packet voice and fax traffic via a shared two-way cable system and IP backbone network. The Cisco uBR924 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 uBR924 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 uBR924 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 uBR924 cable access router functions as a cable modem at the subscriber site to convey data communications on the cable television system.

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 uBR924 router, based on the available images in Cisco IOS Release 12.2. The Cisco uBR924 Cable Access Router can also function as an advanced router, providing WAN data connectivity in a variety of configurations.


Note All Cisco uBR924 Cable Access Router images support DOCSIS Baseline Privacy Interface (BPI) encryption. BPI is subject to export restrictions.


Cisco uBR924 Cable Access Router

The Cisco uBR924 Cable Access Router features a single F-connector interface to the cable system, four RJ-45 (10BASE-T 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 Easy IP, Firewall Phase II (Cisco Secure Integrated Software), and IP Security (IPSec).

Memory Recommendations

For memory recommendations for the Cisco uBR924 cable access router in Cisco IOS Release 12.2, refer to the "Memory Recommendations" section.

Headend Interoperability

Cisco Cable Clock Card Support

When using Cisco IOS Release 12.1(1)T 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 uBR7200 series universal broadband router with the Cisco Cable Clock Card feature.

DOCSIS Concatenation

If using DOCSIS concatenation with a 16-QAM (quadrature amplitude modulation) symbol rate, the CMTS must be configured for Unique Word 16 in the preamble for both short and long data burst profiles. On the Cisco uBR7200 series universal broadband routers, use the cable modulation-profile global configuration command and specify "uw16" for both the long and short modulation profiles.

DOCSIS 1.0+ Extensions

Cisco IOS Release 12.2 images support the Cisco DOCSIS 1.0+ Extensions, which include dynamic multi-SID assignment and concatenation. To use the dynamic multi-SID and concatenation features, both the Cisco uBR924 router and the CMTS router must support them. If you are using the Cisco uBR7200 series headend equipment as the CMTS router, Cisco IOS Release 12.0(7)XR, Release 12.1(1)T, or greater is required on both the Cisco uBR924 cable access router and the CMTS router to ensure that these features are activated.

To configure the Cisco uBR924 cable access router to support multiple classes of service, use either the Cisco Subscriber Registration Center (CSRC) tool or the configuration file editor of your choice. DOCSIS configuration files can contain multiple classes of service (CoS) to support voice. The first CoS is used for data (and voice if no other CoS is defined), and up to three additional classes of service can be defined to give higher priority for voice traffic.

IPSec Encryption Support

To use IPSec encryption, both the Cisco uBR924 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 desired that the CMTS act as an IPSec gateway.)


Note The IPSec feature set encrypts traffic sent between endpoints, such as between two Cisco uBR924 cable access routers, to protect traffic sent across the Internet and other unprotected networks. The DOCSIS BPI feature encrypts traffic on the cable interface, between the Cisco uBR924 cable access router and the CMTS. To use BPI encryption, both the Cisco uBR924 cable access router and the CMTS must support and enable BPI encryption.


Voice Protocol Support

When using a voice-enabled 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. The gatekeeper must be running Cisco IOS Release 12.0(5)T or greater 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 voice-enabled Cisco IOS Release 12.1 images. SGCP is an alternative to the H.323 protocol that provides signaling and feature negotiation via a remote Call Agent. 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.

Hardware Supported

The Cisco uBR924 cable access router contains the following interfaces:

A single F-connector interface to the cable system.

Four RJ-45 (10BASE-T Ethernet) hub ports to connect:

Up to 254 computers directly to the four Ethernet hub ports at the rear of the Cisco uBR924 router when operating in bridging mode. When operating in routing mode, all four Ethernet hub ports can be connected directly to four computers.


Note For releases earlier than Cisco IOS Release 12.0(5)T—not 12.1(5)T but 12.0(5)T—, the four Ethernet hub ports support only a maximum of three computers when operating in bridging mode. (The maximum of three computers is for all four ports together—not three computers per port).


One of the four Ethernet hub ports at the rear of the Cisco uBR924 router can be connected to an Ethernet hub, which then connects additional computers or devices at the site when operating in routing or bridging mode.

Two RJ-11 Foreign Exchange Station (FXS) ports connect telephones and fax devices to the cable system and IP backbone; the router ships from the Cisco factory with the voice ports enabled. The FXS ports on the Cisco uBR924 router can be connected to analog telephones or fax machines but cannot be used for PBX extensions.

One RJ-11 port connects to a standard, analog telephone line (optional) to provide a backup plain old telephone service (POTS) connection to the Public Switched Telephone Network (PSTN). The backup port becomes operational if the Cisco uBR924 router loses power or its connection to the cable network.

One RJ-45 console port (optional) to connect to a laptop computer or console terminal when locally configuring the Cisco uBR924 router; the router ships from the Cisco factory with the console port enabled.

For detailed descriptions of the new hardware features, see the "New and Changed Information" section on page 93.

Limitations and Restrictions

Bridging Support

The Cisco uBR924 Cable Access Router interoperates with DOCSIS cable networks. Cisco IOS Release 12.1 T does not support bridging traffic across a non-DOCSIS cable network.

Detecting Carrier Sense Errors

The Cisco uBR924 cable access router cannot detect carrier sense errors on the four Ethernet ports that connect the router to the subscriber's local area network. This limitation is because the four Ethernet ports are provided by an internal hub that always provides a carrier sense signal to the Cisco IOS software, even if no Ethernet devices are connected to the external ports. In particular, this means that the dot3StatsCarrierSenseErrors attribute in ETHERLIKE-MIB (RFC 2665) will never indicate any drops in carrier of the Ethernet interface.

DOCSIS CLI Commands Are Removed

To comply with DOCSIS requirements that restrict access to commands that change DOCSIS parameters, Cisco IOS Release 12.1(2)T has removed a number of commands from the command line interface (CLI). These commands are now reserved exclusively for DOCSIS use.

IP Address Negotiation

The DOCSIS specifications require that a cable modem obtain its IP address at power-on or reset from a Dynamic Host Configuration Protocol (DHCP) server that is available through the cable interface. For this reason, the Cisco uBR924 cable access router defaults to a configuration that uses the ip address docsis command for the cable interface. It is not possible to override this setting by specifying a specific static IP address; to assign a static IP address to the Cisco uBR924 router, configure the DHCP server so that it assigns the desired IP address on the basis of the unit's MAC address. However, service providers should warn subscribers that changes in the topology of the cable network—because of traffic levels, growth, or changes to the cable plant and other hardware—might still require changing the subnets and IP addresses assigned to a particular cable modem.


Note The ip address negotiated and ip address dhcp commands cannot be used on the cable interface. Previous versions of Cisco IOS used these commands for the Cisco uBR924 router but Release 12.2 uses the ip address docsis command to avoid conflicts these other commands might have with DOCSIS operations.


Upgrading Software Images Using BPI

To enable BPI encryption, the Cisco uBR924 cable access router must use a Cisco IOS image that supports BPI encryption. If the router's current software image does not support BPI encryption (or if the current software image is corrupted), you must disable BPI encryption in the DOCSIS configuration file and reset the router before you will be able to download a new software image.

Using Access Lists with IPSec Images

Access lists 100 and 101 should never be manually configured on the Cisco uBR924 cable access router. Configuring these access lists with Cisco IOS Release 12.1 T images that support any form of IPSec encryption can crash the router. Use any access lists 102 through 199 instead.

Using Multiple PCs with the Cisco uBR924 Cable Access Router

The "MAX CPE" parameter in a Cisco uBR924 cable access router's DOCSIS configuration file determines how many PCs (or other customer premises equipment [CPE] devices) are supported by the Cisco uBR924 cable access router. The default value for the "MAX CPE" parameter is 1, which means only one PC can be connected to the Cisco uBR924 cable access router.

The DOCSIS 1.0 specification states that a CMTS cannot age out MAC addresses for CPE devices, so the first PC that is connected to the Cisco uBR924 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 result would occur if a user decided to move a PC from one Cisco uBR924 router to another.

To allow a subscriber to replace an existing PC or NIC, the following workarounds are possible:

If using a Cisco uBR7200 series router as the CMTS, enter the clear cable host MAC-address command on the Cisco uBR7200 series router to remove the PC's MAC address from the router's internal address tables. The new PC will be rediscovered and associated with the correct Cisco uBR924 cable access router during the next DHCP lease cycle.

Increase the value of the "MAX CPE" parameter in the Cisco uBR924 cable access router's DOCSIS configuration file so that it can accommodate the desired number of PCs. Reset the Cisco uBR924 cable access router to force it to load the new configuration file.

Using the Reset Switch

The reset switch on the back panel of the Cisco uBR924 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 uBR924 Cable Access Router

CPE Device Filtering

In Cisco IOS Release 12.1(2)T and above, the "docsDevCpeIpMax" attribute defaults to -1 instead of the previous default of 1. This attribute controls the maximum number of CPE devices that can pass traffic through the router from its Ethernet interface as follows:

When "docsDevCpeIpMax" is set to -1, the Cisco uBR924 cable access router does not filter any IP packets on the basis of their IP addresses, and CPE IP addresses are not added to the "docsDevFilterCpeTable" table.

When "docsDevCpeIpMax" is set to 0, the Cisco uBR924 cable access router does not filter IP packets on the basis of the IP addresses. However, the source IP addresses are still entered into the "docsDevFilterCpeTable" table.

When "docsDevCpeIpMax" is set to a positive integer, it specifies the maximum number of IP addresses that can be entered into the "docsDevFilterCpeTable" table. The Cisco uBR924 cable access router compares the source IP address for packets it receives from CPE devices to the addresses in this table. If a match is found, the packet is processed; otherwise, the packet is dropped.

CPE IP address filtering is done as part of the following process:

1. MAC address filtering—Packets are filtered on the basis of the CPE device's MAC address. This is controlled by the value of the "MAX CPE" parameter, which is set in the DOCSIS configuration file.

2. Link Level Control (LLC) filtering—Packets are filtered on the basis of the packet's protocol. This is controlled by the "docsDevFilterLLCTable" table.

3. CPE IP address filtering—Packets are filtered on the basis of the CPE device's IP address, as controlled by the "docsDevCpeIpMax" attribute and the "docsDevFilterCpeTable" table.

4. Access list filtering—Packets are filtered on the basis of access lists. IP filtering is controlled by the "docsDevFilterIpTable" table, and SNMP access filters are controlled by the "docsDevNmAccessTable" table.

Refer to the DOCS-CABLE-DEVICE-MIB.my MIB for more information on the attributes and tables listed above.

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.

Supplemental and Corrected Text for the Online Feature Module

Troubleshooting Tips for the 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 IRC (Incrementally Related Carrier) and HRC (Harmonically Related Carrier) plans are supported. Most of the IRC channel slots overlap the EIA plan. For the Cisco uBR924 cable access router, both the IRC and HRC plans are supported.

"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 may increase the amount of 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 very first time it is added to the cable system."

Supported MIBs

The Cisco uBR924 cable access router supports the following categories of MIBs:

Cable Device MIBs—These MIBs are for DOCSIS-compliant cable modems and CMTS to record statistics related to the configuration and status of the cable modem. These MIBs include support for the MIB attributes defined in RFC 2669.

Cisco's Standard MIBs—These MIBs are common across most of Cisco's router platforms. If your network management applications are already configured to support other Cisco routers, such as the Cisco 2600 series or Cisco 7200 series, no further configuration is needed unless the version of Cisco IOS software being used has updated these MIBs.

Cisco Voice MIBs—These MIBs are common across Cisco's router platforms that support Voice over IP (VoIP). These MIBs provide access to voice-related parameters and statistics, including the SGCP protocol.

Radio Frequency Interface (RFI) MIBs—These MIBs are for DOCSIS-compliant radio frequency interfaces in cable modems and CMTS. These MIBs include support for the MIB attributes defined in RFC 2670.

SNMP Standard MIBs—These are the MIBs required by any agent supporting SNMPv1 or SNMPv2 network management.

Cable-specific MIBs—These MIBs provide information about the cable interface and related information on the Cisco uBR924 Cable Access Router. They include both DOCSIS-required MIBs and Cisco-specific enterprise MIBs. If your network management applications have not already been configured for the Cisco uBR924 Cable Access Router, these MIBs must be loaded.

Deprecated MIBs—These MIBs were supported in earlier releases of Cisco IOS software but have been replaced by more standardized, scalable MIBs. Network management applications and scripts should convert to the replacement MIBs as soon as possible.

Cable Device MIBs

The Cisco uBR924 Cable Access Router supports the Cable Device MIB, which is defined by RFC 2669 and describes 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:

"docsDevBase" group extends the MIB-II "system" group with objects needed for cable device system management.

"docsDevNmAccess" group provides a minimum level of SNMP access security.

"docsDevSoftware" group provides information for network downloadable software upgrades.

"docsDevServe" group provides information about the progress of interaction with various provisioning servers.

"docsDevEven" group provides information about the progress of reporting.

"docsDevFilter" group configures filters at the link layer and IP layer for bridge data traffic.

The Cable Device MIB is very similar to the RFI MIB in that both allow access to statistics; they are different in that 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

The Cisco uBR924 Cable Access Router supports the Cisco Standard MIBs, which consist of the following components:

CISCO-PRODUCT-MIB

CISCO-SYSLOG-MIB

CISCO-FLASH-MIB

BRIDGE-MIB

IF-MIB (RFC 2233)

CiscoWorks/CiscoView support


Note The Cisco Management Information Base (MIB) User Quick Reference publication is no longer published. For the latest list of MIBs supported by Cisco, refer to the Cisco Network Management Toolkit on Cisco.com. From the Cisco.com home page, click the following:
Products and Services: Cisco IOS Software: Cisco IOS Software Releases 12.2: Troubleshooting: Bug Toolkit.


Cisco Voice MIBs

The Cisco uBR924 Cable Access Router supports the Cisco Voice MIBs, which consist of the following components:

CISCO-VOICE-IF-MIB

CISCO-VOICE-DIAL-CONTROL-MIB

CISCO-VOICE-ANALOG-MIB

CISCO-DIAL-CONTROL-MIB

DIAL-CONTROL-MIB

SGCP-MIB

XGCP-MIB

Radio Frequency Interface MIBs

The Cisco uBR924 Cable Access Router supports the Radio Frequency Interface (RFI) MIB. The RFI MIB module is defined in RFC 2670 and describes DOCSIS-compliant radio frequency interfaces in cable modems and CMTS. On the cable modem, RFI MIB entries provide:

Upstream and downstream channel characteristics

Class-of-service attributes

Physical signal quality of the downstream channels

Attributes of cable access router MAC interface

Status of several MAC layer counters

The RFI MIB includes tables that describe 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 and MGCP MIBs

The Cisco uBR924 Cable Access Router supports the Simple Gateway Control Protocol (SGCP) and Media Gateway Control Protocol (MGCP) through a single MIB (XGCP-MIB). This MIB supports configuration, performance, and fault management of the SGCP and MGCP interfaces.

The key attributes of this MIB are as follows:

xgcplnBadVersions—Number of incoming messages delivered to the protocol entity and that are for an unsupported protocol version.

xgcpRequestTimeOut—Timeout value used for retransmitting an unacknowledged message.

xgcpRequestRetries—Number of retries for a request that exceeds timeout.

xgcpAdminStatus—Desired state of the protocol entity.

xgcpOperStatus—Current operational status of the protocol entity.

xgcpUnRecognizedPackets—Number of unrecognized packets since reset.

xgcpMsgStatTable—Table that contains SGCP statistics information since reset.

xgcpMsgStatEntry—Row in the "xgcpMsgStatTable" that contains information about SGCP message statistics per IP address of the Media Gateway Controller (MGC).

xgcpIPAddress—IP address of the MGC.

xgcpSuccessMessages—Number of successful messages that communicate with the MGC on that IP address.

xgcpFailMessages—Number of failed messages that communicate with the MGC on that IP address.

xgcpUpDownNotification—Notification sent when the protocol status changes between up and down.


Note For complete details on the SGCP and MGCP MIB, refer to the XGCP-MIB.my file on the Cisco.com MIB website.

Deprecated MIBs

A number of Cisco-provided MIBs have been replaced with more scalable, standardized MIBs. These deprecated MIBs have filenames that start with "OLD", and they first appeared in Cisco IOS Release 10.2. The functionality of these MIBs has already been incorporated into replacement MIBs, but the old MIBs are still present to support existing Cisco IOS products or network management system (NMS) applications. However, because the deprecated MIBs will be removed from support in the future, you should update your network management applications and scripts to refer to the table names and attributes that are found in the replacement MIBs.

Table 4 shows the deprecated MIBs and their replacements. In most cases, SNMPv1 and SNMPv2 replacements are available, but some MIBs are available only in one version. A few of the deprecated MIBs do not have replacement MIBs; support for these MIBs will be discontinued in a future release of Cisco IOS software.

Additional Notes for the Cisco 1400 Series Routers

Multipartition Flash Default

When using a multipartition Flash memory card, the various Flash partitions are referred to as "flash:1:", "flash:2:", and so on. If you specify only "flash" in a multipartition Flash, the parser assumes "flash:1:". For example, if you enter the show flash all command the parser defaults to "show flash:1: all" and only the Flash information for the first partition displays. To see information for all Flash memory partitions, enter show flash ?. This will list all of the valid partitions. Then enter show flash:xx: all on each valid partition.

Traffic Shaping

On the ATM25 interface of the Cisco 1400 series there are two types of traffic shaping: hardware-based and software-based. Hardware-based traffic shaping is provided by the ATM SAR chip and is enabled on a per-PVC basis by one of the following Cisco IOS PVC configuration commands:

ubr <peak-cell-rate>

ubr+ <peak-cell-rate> <minimum-guaranteed-cell-rate>

vbr-nrt <peak-cell-rate> <sustainable-cell-rate> <maximum-burst-size>

The SAR chip has "rate counters" that control the rate at which the current buffer up for segmentation is going to be transmitted. Ideally, the SAR chip could be programmed with values for all of the above command parameters. Unfortunately, it only has the rate counters, which specify a divisor of the basic line rate of 25 Mbps and which really sets the maximum transmission rate (peak-cell-rate) for the channel. Note that with the ubr and ubr+ commands, the rate counter for the PVC is obtained from the <peak-cell-rate> parameter. With the vbr-nrt command, the rate counter is obtained from the <sustainable-cell-rate> parameter. While the <minimum-guaranteed-cell-rate> parameter in the ubr+ command and the <peak-cell-rate> parameter in the vbr-nrt command can be specified by the user, they are ignored by the ATM25 driver.

Software-based traffic shaping is enabled on a per-interface basis via the traffic-shape interface configuration command. For performance reasons, and since for ATM interfaces you most likely want to do shaping on a per-PVC basis, the ATM driver does not support software-based traffic shaping while fast-switching. However, if fastswitching is disabled and the traffic-shape interface configuration command is enabled, software traffic shaping will occur. (See CSCdk28377 for more information.)

Additional Notes for the Cisco 1700 Series Routers

Using the boot flash Command

Booting a Cisco 1700 series router with the boot flash or boot system flash commands results in unpredictable behavior. To work around this problem, be sure to enter a colon (:) following both commands (for example, boot flash: or boot system flash:).

Fan Operation in Cisco 1700 Series Routers

Be advised that the fans in the Cisco 1700 series routers stay off until thermally activated (45°C/115°F).

T.38 Fax Protocol Support on the Cisco 1750 Platform

The T.38 fax protocol is supported on the Cisco 1750 platform. The T.38 fax protocol can be enabled by configuring the fax protocol t38 command in dial-peer configuration mode.

The T.38 fax protocol is supported in Cisco IOS Release 12.2(3) in all Cisco 1750 platform voice images. Refer to the following document for additional information:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121t/121t3/dt_t38fx.htm

Multipartition Flash Defaults

When using a multipartition flash card, the various flash partitions are referred to as "flash:1:", "flash:2:", etc. If you specify only "flash" in a multipartition flash, the parser assumes "flash:1:." For example, if you enter show flash all the parser defaults to "show flash:1: all" and only the flash information for the first partition displays. To see information for all flash partitions, enter show flash ?. This will list all of the valid partitions. Then enter show flash:xx: all on each valid partition.

Additional Notes for 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:

Cisco CLI

HTTP-based configuration server

SNMP-based MIB

The HTTP-based interface allows configuration from any web browser such as Netscape Navigator or Microsoft Explorer. The Simple Network Management Protocol (SNMP) MIB allows management of the Cisco MC3810 from SNMP managers (for example, HP OpenView).

Memory Recommendations

For memory recommendations for the Cisco MC3810 in Cisco IOS Release 12.2, refer to the "Memory Recommendations" section.

Additional Notes for the Cisco MC3810 Multiservice Access Concentrator

Using the Cisco MC3810 with QSIG or BRI

Serial port 1 is restricted to DCE operation when the following occurs:

Q (point of the ISDN model) Signaling (QSIG) is enabled.

BRI voice module (BVM) is installed and BRI is enabled.

BRI S/T backup port is installed and enabled on the multiflex trunk module (MFT).

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).

Connections to the 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.

Switched Access from the PSTN

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.

Nonswitched Calls

The same opportunity for illicit use does not exist for nonswitched 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.

Additional Notes for the Cisco Catalyst 4500 Access Gateway Module

Tighten Screws on VICs and WICs

You must tighten the screws on the voice interface cards (VICs) and WAN interface cards (WICs) mounted on the Access Gateway module. If the screws are not properly tightened, the VIC or WIC may malfunction.

TDM Clocking

The TDM clock reference on the Access Gateway module can be derived from one of seven sources. These are the free-running on-board clock and the two recovered clock sources from each VIC slot that contains an E1/T1 card.

The default reference is the on-board clock. The frame-clock-select command can be used to select one of the E1/T1 ports as the primary reference. This command can also be used to select up to three prioritized backups that can be used if the primary clock fails. Switchover to a backup source is nonrevertive; the system does not switch back to a higher priority clock if it recovers after a failure.

The command has the following syntax:

[no] frame-clock-select priority E1/T1 slot/port

The clock source with priority 1 is the primary reference, and the clock with priority 4 is the lowest priority backup.

The clock reference selection using the frame-clock-select command is independent of the clock selection between line or internal on an E1/T1 controller. Framing and cyclic redundancy check (CRC) errors because of clock slips may be observed on E1/T1 interfaces if the onboard clock is used as the reference.

Need to Support 56-Kbps Operation for Slot 3 WIC

The 8260 Rev1A device, which is being used in the Access Gateway module hardware, has a defect that can cause data corruption when configuring the MCC SI RAM for two entries (7 bits forming the 56-kbps channel and 1 bit being discarded).

As a workaround, three SI RAM entries would have to be used, but the Access Gateway module does not have enough room available. Therefore, only 64-kbps channels will be supported on the Access Gateway module.

If absolutely required, we could implement this feature in Access Gateway module slots 1 and 2 using the SCCs and limit it to two channels or super-channels per Access Gateway module slot. This requires more design work and will not be addressed unless really needed.

Customers that need 56-kbps should use the WIC-56K4 WIC.

Microcode and Modem Code Software

Feature Support

Introduction

The Cisco AS5300 universal access server is a versatile data communications platform that performs the following two functions in a single modular chassis depending on the installed feature cards and Cisco IOS images:

Remote Access Server

Voice Gateway

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).

Microcode and Modem Code Software

Microcode software images are bundled with the system software image—with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards. Table 14 lists the current microcode versions for the Cisco AS5300 universal access server.

You could have received a later version of modem code than the one bundled with the Cisco IOS software. The modem code in Flash memory is mapped to the modems. Unless you fully understand how Cisco IOS software uses modem code, it is important to keep the factory configuration.

Additional Notes for the Cisco AS5800

Introduction

The Cisco AS5800 universal access server is a high-density, ISDN and modem WAN aggregation system that provides digital and analog call termination. It is 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, a router shelf, and (optionally) a system controller:

The Cisco DS5814 (dial shelf) has 14 slots and can support 1 or 2 dial shelf controller cards and up to 12 feature cards to provide full analog modem and ISDN coverage. The dial shelf supports up to 2047 simultaneous analog and/or digital calls. Analog calls are terminated by a feature card that is loaded with integrated modems. ISDN calls are terminated onboard the trunk card on High-Level Data Link Control (HDLC) controllers. The E1 trunk, CT3 trunk, and T1 trunk cards include CSUs and have either 12 E1 ports or 12 T1 ports that can operate as PRI interfaces or channelized interfaces in any combination. The CT3 trunk supports 28 T1s.


Note T1 and E1 cards are not supported in the same box.


The Cisco RS7206VXR (router shelf) contains a network processing engine, an I/O controller, and the egress interfaces, such as High-Speed Serial Interface (HSSI), Fast Ethernet (FE), FDDI, and ATM, and supports either 280W AC-input or 280W DC-input redundant power. The router shelf also may contain one or two dial shelf interconnect port adapters each with a single RJ-45 receptacle, which is used to connect the router shelf to the Cisco 5814 dial shelf. The interconnect port adapter connects directly to the dial shelf controller card on the dial shelf via a Cisco-proprietary cable, customized with jack screws to secure the connection. You must use this specially designed cable that ships with your interconnect port adapter.

The AC-input power shelf is an optional component of the Cisco AS5800 universal access server 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 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 1344 voice ports in a single system, thus offering the highest concentration of Voice over IP (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 Quality of Service (QoS) services that are part of Cisco IOS software.

Cisco AS5800 Voice Feature Card

The Cisco AS5800 Voice Feature card is a full featured voice processing card that supports 192 DSP-based voice ports. Voice processing capabilities include Voice Activity Detection (VAD), comfort noise generation, adaptive jitter buffering, programmable 16- and 32-msec echo cancellation, programmable frame size, and Dual Tone Multiple Frequency (DTMF) detection and generation. The Cisco AS5800 Voice Feature card offers industry-leading DSP density and a wide range of VoIP codecs, including G.711, G.729, G.729a, G.723.1, and Group III real-time fax support, on any port at any time.

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 service provider's headend facility.

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. These routers 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-compliant cable modems (CMs) and set top boxes (STBs).

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 is via 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.

The introduction of the WT2700 Wireless Technology Suite also allows the Cisco uBR7223, the Cisco uBR7246, and the Cisco uBR7246 VXR Universal Broadband Routers to become a two-way high-speed point-to-point broadband fixed wireless system that provides a fixed, dedicated wireless link from one headend site to another. This link delivers full-duplex data in unlicensed U-NII band (5.725 to 5.825 GHz). The WT2700 Wireless Technology Suite includes the point-to-point wireless modem card, which is installed in the Cisco uBR7200 series chassis, and the power feed panel, which is an external component.

The Cisco uBR7200 series routers support IP routing with a wide variety of protocols and combinations of Ethernet, Fast Ethernet, Gigabit Ethernet, serial, High-Speed Serial Interface (HSSI), Packet over SONET (POS) OC-3 and OC-12c, and ATM media.

Cisco IOS Release 12.2 supports cable & fixed wireless system configurations using the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223.

For memory recommendations for the Cisco uBR7200 series universal broadband routers in Cisco IOS Release 12.2, refer to the "Memory Recommendations" section.

System Interoperability

This section clarifies the operation of certain features in the Cisco uBR7200 Series Universal Broadband Routers:

DOCSIS 1.0 Baseline Privacy

DOCSIS Baseline Privacy Interface (BPI) gives subscribers data privacy across the RF network, encrypting traffic flows between the CMTS and the CM. BPI ensures that a CM, uniquely identified by its MAC address, can obtain keying material for services that only it is authorized to access.

To enable BPI, choose software at both the CMTS and the CM that support the mode of operation. For the Cisco uBR7200 series software, choose an image with "k1" in its file name or BPI in the feature set description.

The CM must also support BPI. CMs must have factory-installed RSA private/public key pairs to support internal algorithms to generate key pairs prior to first BPI establishment. BPI must be enabled via the DOCSIS configuration file.


Note RSA stands for Rivest, Shamir, and Adelman, inventors of a public-key cryptographic system.


CM Interoperability

The Cisco uBR7200 series interoperates with the following cable modems:

DOCSIS-based two-way CMs that support basic Internet access, VoIP, or VPN.

Telco-return CMs—To support telco return, use a Cisco uBR7200 series software image that contains "t" in its filename. The telco-return CM must be DOCSIS-based or compliant, and must be configured to support telco return.


Note Some third-party telco-return CMs cannot receive traffic over the same downstream channel as CMs operating on a two-way data system. In these instances, segment your cable plant to allow more than one downstream channel.


EuroDOCSIS CMs or set top boxes (STBs) with integrated EuroDOCSIS CMs using Cisco MC16E Cable Modem Cards and Cisco IOS Release 12.1(1a)T1 or higher. EuroDOCSIS operation support includes 8-MHz Phase Alternating Line (PAL) or Systeme Electronique Couleur Avec Memoire (SECAM) channel plans.

DOCSIS 1.0 Extensions

The Cisco uBR7200 series supports DOCSIS 1.0 quality of service (QoS) extensions that include:

Multi-SID support, allowing the definition of multiple Service IDs (SIDs) on the upstream: Voice traffic can be designated on a higher QoS committed information rate (CIR) secondary SID, while data traffic can be forwarded on a best-effort basis on a primary SID. Secondary SIDs are higher QoS CIR-type classes that have a nonzero minimum reserved rate (CIR-type service). These SIDs receive preferential treatment at the CMTS for grants over any tiered best-effort type data SID of that upstream. Reliable operation with voice requires multiple SIDs—at least two per CM to separate voice from data. In DOCSIS 1.0, SIDs are set up statically. When supporting DOCSIS 1.0 extensions, SIDs can be set up statically or dynamically. Both the CMTS and CM must support this capability.

CM-initiated dynamic MAC messages: Dynamic Service Addition (DSA) and Dynamic Service Deletion (DSD). These messages allow dynamic SIDs to be created and deleted at run-time on a per-VoIP call basis.

Unsolicited grant service (constant bit-rate scheduling) on the upstream: This helps provide a higher-quality channel for upstream VoIP packets from an Integrated Telephony Cable Modem (ITCM) such as the Cisco uBR924 Cable Access Router.

Ability to provide separate downstream rates for any given ITCM, based on the IP-precedence value in the packet: This helps separate voice signaling and data traffic that goes to the same ITCM to address rate shaping purposes.

Concatenation—To increase the per-CM upstream throughput in certain releases of software, Cisco uBR7200 series software supports a concatenated burst of multiple MAC frames from a CM that supports concatenation.


Note All DOCSIS 1.0 extensions are activated only when a CM or Cisco uBR924 that supports these extensions solicits services via dynamic MAC messages or the feature set. If the CMs in your network are pure DOCSIS 1.0-based, they will receive regular DOCSIS 1.0 treatment from the CMTS.


Clock Synchronization

The Cisco uBR7200 series supports clock hardware and software to enable high-quality delivery of IP telephony services through synchronized data transmissions. To support the clock feature set, a Cisco uBR7246 VXR chassis must be used. The Cisco uBR7246 VXR must contain a clock card and an MC16S or MC16E Cable Modem Card. Only the MC16S and the MC16E Cable Modem Cards support the external clock reference from the clock card to distribute that signal to CMs or set top boxes (STBs) attached to the specific network segments. The chassis must be running Cisco IOS Release 12.1(1a)T1 or higher.

Each cable modem must also supports VoIP applications and the clock reference feature set to enable synchronized timing. The Cisco uBR924 Cable Access Router, running Cisco IOS Release 12.0(7)T or later, supports the clock reference feature set automatically.

Feature Support

For feature support in Cisco IOS Release 12.2, refer to the "Feature Support" section.

Limitations and Restrictions

Cisco IOS Release 12.1(5)T 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.

Wireless Modem Card Support for Port Adapters

Not all port adapters are supported with the point-to-point wireless modem card. The HSSI, 10BASE-T Ethernet, 100BASE-T Ethernet, serial Frame Relay, ATM, and POS interfaces are fully supported. The Gigabit Ethernet port adapter was not supported with the point-to-point wireless modem card at the time the Cisco IOS Release 12.2 software was released.

Wireless System Power Feed Panel

The cable that supplies -48VDC to the wireless system's power feed panel should not exceed 3 meters in length.

Supported MIBS

The Cisco uBR7200 Series Universal Broadband Routers support the following categories of MIBs:

SNMP standard MIBs—These are the MIBs that are required by any agent that supports SNMPv1 or SNMPv2 network management.

Cisco's platform and network-layer enterprise MIBs—Common across most of Cisco's router platforms. If your network management applications are already configured to support other Cisco routers, such as the 2600 series or 7200 series, no further configuration is needed unless the version of Cisco IOS software being used has updated these MIBs.

Cable-specific and wireless-specific MIBs—Provide information about the cable and wireless interfaces and related information on the uBR7200 series routers. They include both DOCSIS-specific MIBs and Cisco-specific enterprise MIBs. If your network management applications have not already been configured for the uBR7200 series routers, these MIBs must be loaded.

Deprecated MIBs—Supported in earlier releases of Cisco IOS software but have been replaced by more standardized, scalable MIBs. Network Management applications and scripts should convert to the replacement MIBs as soon as possible.

The cable-specific and wireless-specific MIBs are described in the following sections. For information on the SNMP standard MIBs and Cisco's platform and network-layer enterprise MIBs, see Cisco's MIB web site at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.

Cable-Specific and Wireless-Specific MIBs

Table 21 shows the cable-specific and wireless-specific MIBs that are supported on the Cisco uBR7200 Series Universal Broadband Routers. The table also provides a brief description of each MIB 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. Because of interdependencies, the MIBs must be loaded in the order given in the table.


Note The names given in Table 21 are the filenames for the MIBs as they exist on Cisco's FTP site http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml. Most MIBs are available in both SNMPv1 and SNMPv2 versions; the SNMPv1 versions have V1SMI as part of their filenames.

Introduction

The Cisco Signaling Link Terminal (SLT) enables service providers to reliably transport SS7 protocols across an IP network. The Cisco SLT uses the Cisco IOS SS7 Signaling Link Terminal feature set, providing reliable interoperability with the Cisco Media Gateway Controller. The Cisco SLT is responsible for terminating the Message Transfer Part (MTP) 1 and MTP 2 layers of the SS7 protocol stack. Using Cisco's Reliable User Datagram Protocol (RUDP), the Cisco SLT backhauls, or transports, upper-layer SS7 protocols across an IP network to the Cisco Media Gateway Controller (Cisco VSC3000 or Cisco SC2200).

In combination with this application-specific version of the Cisco IOS software, the Cisco SLT hardware component leverages the widely deployed Cisco 2600 series multiservice access router. The Cisco 2600 series, driven by a powerful RISC processor, provides the high performance required in complex networking infrastructures.


Note When used as a Cisco Signaling Link Terminal device integrated into a Cisco Media Gateway Controller, the Cisco 2611 has SS7 functionality only; all standard Cisco 2611 software features are disabled when running the Cisco SLT image. In that case, only the Cisco Signaling Link Terminal document and the Cisco Media Gateway Controller documentation are relevant.


When used for Signaling Link Terminal applications, the modular Cisco 2611 dual-Ethernet port router can be configured with dual serial and the multiflex interface cards. The E1 multiflex interface cards offer integrated DSUs and the T1 multiflex interface cards offer integrated CSU/DSUs. For additional flexibility, the multiflex interface cards can also be ordered with a dual-port drop-and-insert capability. All of these interface cards are Field Replaceable Units (FRUs).

The Cisco SLT supports only the SS7 MTP 2 serial protocol. Therefore, the serial interfaces cannot be configured for other protocols such as HDLC, PPP, X.25, LAPB, and Frame Relay.

The Cisco SLT functions as a component of several solutions that are currently under development. Participants in lab trials can obtain solution documentation from their Cisco representative.
