Supports only embedded multimedia terminal adapter (E-MTA) clients. Standalone MTA (S-MTA) clients are not supported.
PacketCable operations can be configured together with HCCP N+1 redundancy, but the PacketCable states are not synchronized between the Working and Protect interfaces. If a switchover occurs, existing voice calls continue, but when the user hangs up, PacketCable event messages are not generated because the Protect interface is not aware of the previous call states. However, new voice calls can be made and proceed in the normal fashion.
The 200,000 Hz channel width cannot be used on upstreams that support PacketCable voice calls, or on any upstreams that use Unsolicited Grant Service (UGS) or UGS with Activity Detection (UGS-AD) service flows. Using this small a channel width with voice and other UGS/UGS-AD service flows results in calls being rejected because of “DSA MULTIPLE ERRORS”.
This section provides an overview and other information about PacketCable operations, the components of a PacketCable network, and how they interact with the other components of a DOCSIS cable networks.
PacketCable is a program initiative from Cablelabs and its associated vendors to establish a standard way of providing packet-based, real-time video and other multimedia traffic over hybrid fiber-coaxial (HFC) cable networks. The PacketCable specification is built upon the Data-over-Cable System Interface Specifications (DOCSIS) 1.1, but it extends the DOCSIS protocol with several other protocols for use over noncable networks, such as the Internet and the public switched telephone network (PSTN).
This allows PacketCable to be an end-to-end solution for traffic that originates or terminates on a cable network, simplifying the task of providing multimedia services over an infrastructure composed of disparate networks and media types. It also provides an integrated approach to end-to-end call signaling, provisioning, quality of service (QoS), security, billing, and network management.
Emergency 911 Features
The PacketCable Emergency 911 cable interface line card prioritization feature enables cable interface line cards that are supporting an Emergency 911 call to be given automatic priority over cable interface line cards supporting non-emergency voice calls, even in the case of HCCP switchover events. In such cases, Protect HCCP line card interfaces automatically prioritize service to Emergency 911 voice calls, should Working HCCP cable interface line cards be disrupted. This feature is enabled by default, and may not be disabled with manual configuration.
Note |
Emergency 911 cable interface line card prioritization applies only to PacketCable voice calls. |
During HCCP switchover events, cable modems recover in the following sequence:
To view information about Emergency 911 voice events and cable interface line card prioritization on the Cisco CMTS router, use the show hccp, show cable calls, and show hccp event-history commands in privileged EXEC mode.
The enhanced informational support for PacketCable Emergency 911 calls on the Cisco CMTS router provides the following information and related history:
This feature is enabled and supported with the following configuration and show commands:
To set the call window (in minutes) during which the Cisco CMTS router maintains records of Emergency 911 calls, use the cable high-priority-call-window command in global configuration mode. To remove the call window configuration from the Cisco CMTS router, use the no form of this command:
A PacketCable network contains a number of components. Some components are the same as those that exist in a DOCSIS 1.1 network, while other components are new entities that create the end-to-end infrastructure that the PacketCable network needs to establish calls. Wherever possible, the PacketCable components and protocols build on existing protocols and infrastructures to simplify implementation and interoperability.
Note |
See the DOCSIS 1.1 specifications for information about cable modem and CMTS operations. |
Note |
The CMS implements several protocols on top of the Common Open Policy Service (COPS) protocol to communicate with the rest of the PacketCable network. |
Note |
A PacketCable network can contain multiple GCs, although only one server at a time is in control of any particular call. Typically, the same workstation provides both the CMS and GC servers. |
A key feature of a PacketCable network is a dynamic quality of service (DQoS) capability that is similar to the dynamic services provided by DOCSIS 1.1. However, DOCSIS 1.1 DQoS authorizes and provisions services only in the cable network and does not reserve the resources needed to propagate a call from one endpoint to another across the network.
The PacketCable DQoS extends the DOCSIS 1.1 services across the entire network, so that resources can be dynamically authorized and provisioned from one endpoint to another. This prevents possible theft-of-service attacks and guarantees customers the services they are authorized to use.
Note |
PacketCable 1.0 requires that DOCSIS 1.1 be used for resource reservation within the cable network for E-MTA clients. |
The PacketCable DQoS model uses a two-stage resource reservation process, in which resources are first reserved and then committed. This allows a bidirectional reservation process that ensures that resources are available at both endpoints of the connection before actually placing the call.
When an MTA makes a call request, the local CMTS communicates with the gate controller to authorize the call’s resources. After the resources are authorized, the CMTS reserves the local resources while it negotiates with the remote end for the resources that are required at that end.
Note |
The CMTS uses DOCSIS 1.1 Dynamic Service Addition (DSA) messages to reserve the resources, and then uses Dynamic Service Change (DSC) messages to commit the resources. |
When all required resources are available, the local CMTS and remote CMTS both commit the resources, allowing traffic to flow. Usage accounting and billing do not begin until the remote MTA picks up and the call is actually in progress.
The DQoS model ensures that both endpoints of a call, as well as the backbone network, have reserved the same bandwidth, and that the bandwidth is reserved only while the call is in progress. When a call terminates, all portions of the network can release the call’s resources and make them available for other users.
DOCSIS 1.1 networks use service flows to implement different QoS policies, but service flows exist only within the cable network. To control the service flows and to extend them across the entire network, a PacketCable network creates and maintains “gates.”
A gate is a logical entity created on the CMTS at each side of a connection that authorizes and establishes a particular DQoS traffic flow. The CMTS communicates with the gate controller to coordinate the creation of matching gates at each side of the connection.
Gates are unidirectional, so separate gates are required for the downstream and upstream traffic flows. The same gate ID, however, is usually used for the downstream and upstream gates for a call. Each CMTS maintains its own set of gates, so a bidirectional traffic flow requires four gates to be created, two gates on the local CMTS and two gates on the remote CMTS.
For a typical call, gates progress through the following stages to create a DQoS traffic flow:
DQoSLite is a modem centric solution without notion of gates, to validate and deliver residential voice services over IPv6 to reclaim IPv4 address space. CMTS does not participate in resource reservation and authorization.
DQoSLite leverages elements from PacketCable 2.0. It is SIP based, it's provision mechanism is similar to PacketCable 2.0 and it can be part of an IP Multimedia Subsystem (IMS) infrastructure for the ISP.
The key factors for deploying IPv6 voice solution on this new DQoSLite infrastructure are as follows:
It is SIP or IMS based.
Support for a wide range of multimedia services.
To reclaim some IPv4 address space.
This feature is enabled and supported with the following configuration and show commands:
packetcale authorize vanilla-docsis-mta
show cable modem { ip-address| mac-address} qos
show cable modem { ip-address| mac-address} service-flow
show interface cable slot/ subslot/ cable-interface-index sid sid
show interface cable slot/ subslot/ cable-interface-index service-flow sfid
DOCSIS 2.0 mandates unique Transaction IDs (TAIDs) across transactions. The TAIDs must be unique and not incremented. The TAIDs are assigned by the senders and sometimes the TAID timeout is mismatched between senders and receivers. This affects the uniqueness of the TAID.
A TAID can be reused when the sender finishes a transaction. Similarly, DOCSIS allows the receiver to identify a transaction by TAID without the SFID. Problems arise in DSD transaction and DSA/DSC interrupted transactions, when these two requirements are combined.
The uniqueness of TAID must be ensured to resolve the interoperability issue. This is done by making the CMTS wait until T10 to reuse the same TAID. A new TAID allocation algorithm is used to fulfill this requirement.
It creates a TAID pool to replace the existing 16-bit counter. This TAID pool is monitored by timers to track the TAID expiration. A flag is assigned to each TAID in the pool to indicate its availability. When new TAID is requested, the dynamic service process checks the availability of the TAID. If the TAID is available, it is allocated to the new service flow, else the request is rejected.
Once the TAID is allocated, the timer starts with T10 expiration time and the TAID flag is set to FALSE to indicate the unavailability of TAID. The dynamic service process keeps track of the timer. When the time expires, the timer stops and the flag is set to TRUE to indicate the availability of TAID.
The TAID pool is allocated and initialized at the process initialization. All timers associated with the TAIDs are added as leaf timers to the process' parent timer.
The PacketCable Subscriber ID feature adds a subscriber ID to all Gate Control messages and enhances error codes returned from the Cisco CMTS router.
Previously, the Gate ID was unique only to individual CMTS systems, with the CMTS proxying all CMS Gate Control messaging through a central device, which manages the CMTS connections on behalf of the CMS. The CMS had a single Common Open Policy Service (COPS) association to the proxy device. Therefore, the Gate IDs could be duplicated when using multiple CMTS systems.
A subscriber ID is added to each Gate Control message to disambiguate the Gate IDs between the CMS and proxy device. The subscriber ID parameter is added to the following COPS messages:
The subscriber ID is available at the CMS and is used in the Gate-Set messages. Additionally, the error codes returned from CMTS or its proxy are enhanced to include more specific information about gate operation failures.
To enable this feature, use the packetcable gate send-subscriberID command in global configuration mode.
The PacketCable feature offers the following benefits to service providers and their customers:
PacketCable allows cable operators the ability to offer multimedia, real-time services, in addition to data connectivity, across their entire network. These services could include basic telephony with lifeline support, as well as telephony that offers competitive extended calling services. Operators can deploy new services while heavily leveraging their existing network infrastructures.
The widespread use of IP as the standard transport mechanism for data networks today is enabling many advanced Internet applications such as multimedia e-mail, real-time chat, streaming media (including music and video), and videoconferencing. The PacketCable initiative provides the network architecture for a cable operator to deliver these services quickly and economically.
PacketCable provides a standardized, efficient method to provision IP services for individual subscribers, because PacketCable specifications define a uniform, open, and interoperable network. Cable operators are assured of standardized provisioning and the associated lower costs of deployment.
Customer premises equipment (CPE) devices account for a major portion of the capital expense in deploying a VoIP solution at a cable plant. The PacketCable specifications ensure that vendors will build MTA clients that support the voice and other services that cable operators plan to deploy. Because these CPE devices are based on existing DOCSIS-compliant cable modems, time and cost of development is minimized.
Interoperability with the other components of the PacketCable network is also guaranteed because of the standards-based approach to the specifications. Any PacketCable-certified component will be able to interoperate within a network that conforms to the PacketCable standards.
Because PacketCable is built upon the security features available in DOCSIS 1.1, cable operators will be assured of networks that are secure from end to end, with a high standard of security that prevents the most common theft-of-service attacks. The comprehensive, standards-based PacketCable specifications are designed to create a network that is as secure as the public switched telephone network (PSTN).
The PacketCable architecture was designed to accommodate the 1994 Communications Assistance for Law Enforcement Act (CALEA), which requires telecommunications carriers to assist law-enforcement agencies in conducting court-ordered electronic surveillance. PacketCable networks will be able to provide the two types of information that a carrier must provide, depending on the type of court order:
This section contains the following tasks to configure the PacketCable feature. Each task is required unless otherwise identified as optional.
To enable PacketCable operation, use the following commands beginning in user EXEC mode. This is a required procedure.

By default, when PacketCable operations are enabled using the packetcable command, cable modems must follow the PacketCable protocol when requesting Unsolicited Grant Service (UGS) service flows. This prevents DOCSIS cable modems that do not support PacketCable operations from using DOCSIS-style UGS service flows.
If you have a mixed network that contains both PacketCable and non-PacketCable DOCSIS CMs, you can use the packetcable authorize vanilla-docsis-mta command to enable both types of UGS service flows. This is an optional procedure.

Troubleshooting Tips
If the connection between a PacketCable CMS and the Cisco CMTS router is not completely established, and the PacketCable CMS does not correctly terminate the session by sending a TCP FIN message, the connection shows a COPS server in the output of the show cops server command.
The PacketCable Client Accept Timeout feature supports COPS for PacketCable on the Cisco CMTS router. This feature also allows you to set timeout values for COPS Telnet connections on the Cisco CMTS router, and for clearing COPS Telnet sessions.
Telnet errors on the network or Cisco CMTS router might cause incomplete COPS sessions to be created. In order to address this issue, the timeout timer enables clearing and cleaning of allocated resources for the stale COPS Telnet sessions on the Cisco CMTS router.
The timeout timer applies to each COPS Telnet connection on the Cisco CMTS router. When this timeout setting expires, it terminates the Telnet session and clears supporting resources on the Cisco CMTS router.

0000.cab7.7b04 10.10.155.38 C8/1/1/U0 18 R 0:36The PacketCable Multimedia (PCMM) feature is a powerful implementation of the CableLabs® standards for PacketCable Multimedia. PCMM provides enhanced QoS for multimedia applications, voice, and bandwidth-intensive services over a DOCSIS (DOCSIS 1.1 and later versions) network.
The Cisco CMTS router supports DOCSIS QoS for SIP-based telephones and SIP video phones, Bandwidth-on-Demand applications, and network-based gaming applications, all of which place extensive bandwidth demands on the network.
This section provides information about the following aspects of PacketCable Multimedia for the Cisco CMTS router, emphasizing PCMM components that are configured with the Cisco IOS command-line interface later in this document:
The following network components are required to support the PCMM feature:
Figure below provides an architectural overview of the PCMM functionality:
PacketCable Multimedia is a service delivery framework that leverages and uses as much of existing PacketCable 1.x deployments and functionality as possible. Furthermore, PCMM offers powerful enhancements to the VoIP service delivery framework with straightforward CLI implementation. The key enhancements that the PCMM provides are:
High Availability on the Cisco CMTS router accommodates synchronization of service flows created for the PCMM applications and the PCCM gate.
A PacketCable 1.x gate defines QoS parameters and policy-based authorization for subscribers, and a specific envelope of network resources. A PacketCable 1.x gate also maintains classifiers for originating and terminating IP addresses and ports.
The subscriber ID can identify both IPv4 and IPv6 addresses of either the cable modem or the client CPE.
PacketCable 1.x defines a preauthorization model. The PacketCable gates are created and installed at the Cisco CMTS router prior to network resource reservation or activation requests. This process, termed gate control, is managed through a COPS-based policy interface on the Cisco CMTS router.
In PCMM, this COPS-based interface is enhanced for QoS life-cycle management. PCMM gates maintain service flow creation, modification and deletion functions to provide for network-based QoS. Multiple PCMM gates and service flow policies can be maintained on the Cisco CMTS router at a given time, and these PCMM gates are fully interoperable with PacketCable 1.x gates.
When a cable modem subscriber requests bandwidth for a network-intensive application, the network Policy Server sends a Gate-Set message to the Cisco CMTS router. This message contains QoS, service flow, and billing information for this subscriber. This gate profile information is maintained on the Cisco CMTS router, to include PCMM gate states and PCMM state transitions.
The Cisco CMTS router initiates service flows with cable modems, and optimizes DOCSIS resource availability on the Cisco CMTS router for bandwidth-intensive service flows characteristic to PCMM.
On some upstream paths, best effort service flows are configured on some modems with Committed Information Rate (CIR). When a number of bandwidth requests are queued in the modems, only a few requests are sent to the CMTS. This occurs due to congestion of sending requests caused by higher number of service flows, greater traffic and small size of packets. Therefore, only a few best effort service flow requests are satisfied by the CMTS.
Persistent Gate is a feature by which PCMM gate information is maintained for cable modems that go offline. This gate information is quickly enabled after a cable modem returns online. When a cable modem returns online, the Cisco CMTS router scans PCMM gates previously stored, and initiates service to the cable modem according to the respective PCMM gate. This re-enabled service maintains traffic support profiles for that gate, and allocates DOCSIS resources based on the new online subscriber.
PCMM optimizes the IPC handshake between the cable interface line card and the Route Processor (RP) for the Cisco CMTS router. Additional PCMM interface changes from PacketCable 1.x include the handling for COPS interface and distributed cable interface line cards.
PCMM differs from PacketCable 1.x in handling COPS sessions. The COPS sessions on PCMM use TCP port number 3918 by default. Whereas, PacketCable uses the DQoS specification for TCP port requirements and COPS sessions.
When the PCMM module initializes for the first time, a PCMM registry is added to the cable interface line card and the route processor. The PCMM module also registers the PCMM COPS client with the COPS layer on the Cisco CMTS router.
As with PacketCable 1.x, PCMM uses IPC messages for voice support. When PCMM gates are created on the Network Processing Engine (NPE) or route processor (RP), the PCMM gate parameters are sent to cable interface line cards. IPC maintains all communication between the NPE or RP, and the cable interface line cards.
Event messaging is used with PCMM to support billing information based on Gate-Set messages. Event messaging for distributed cable interface line cards originates from the line cards, based on the success of DSX operation.
The PCMM module also registers the PCMM COPS client with the COPS layer.
In unicast transmission, content is sent to a unique user. In multicast transmission, content is sent to multiple users simultaneously.
You can configure a PCMM multicast session range by specifying IPv4 IP addresses and a mask for a PCMM multicast group. The PCMM multicast session range enables the Cisco CMTS router to accept Gate-Set messages from the PCMM Policy Server. If a PCMM multicast session range is configured, the Cisco CMTS router does not allow you to create multicast sessions using other sources such as Internet Group Management Protocol (IGMP) and DOCSIS Set-Top Gateway (DSG).

Enhanced high availability support enables the synchronization of PacketCable and PacketCable MultiMedia (PCMM) gates during switchover events on the Cisco CMTS router. This enhancement is enabled by default.
This functionality uses the existing per-interface HCCP commands that are used to associate the working and protect interfaces in the case of N+1 redundancy.
A PacketCable or PacketCable Multimedia network contains a number of components that benefit from Admission Control QoS. Admission Control manages and optimizes QoS for PacketCable and PCMM in these ways:
When configuring Admission Control with either PacketCable or PCMM, PacketCable or PCMM must be fully operational on the Cisco CMTS headend prior to gaining the benefits from Admission Control.
The multiple grants per interval (MGPI) feature enables the Cisco CMTS router to map multiple PacketCable Multimedia gates (application flows) to a single DOCSIS service flow using UGS traffic profiles of the same cable modem. In other words, the Cisco CMTS router increases the number of grants per interval for each application flow based on a single service flow, resulting in multiple grants per interval.
The MGPI feature supports the flow-aggregated voice MGPI functionality based on CableLabs PacketCable Specification (PKT-SP-MM-I05-091029). The flow-aggregated MGPI functionality allows the application manager to use the UGS traffic profile to explicitly set the number of grants per interval and place several application flows on a single gate. This results in an aggregated view for event messages, volume, and time usage limits.
PacketCable and PCMM services are supported on embedded multimedia terminal adapters (E-MTAs). An E-MTA is a network element that contains the interface to a physical voice device, a network interface, and all signaling and encapsulation functions required for the VoIP transport, class features signaling, and QoS signaling.
To effectively capture signaling information, this functionality buffers signaling for a configured number of PacketCable or PCMM gates. By default, only ten user-configured gate traces are saved in a buffer. After the specified number is reached, any subsequent gate signaling information does not get buffered. When one of the gates being traced is deleted, gate signaling of a new gate is buffered.
Use the cable dynamic-qos trace command in global configuration mode to enable the call trace functionality for PacketCable and PacketCable Multimedia gates on the Cisco CMTS router. You will have to specify the number of subscribers for whom call trace needs to be enabled.
Use the following commands to verify PacketCable and PCMM statistics on the Cisco CMTS router:
To verify dynamic service statistics based on the cable interface, use the show interface cable dynamic-service statistics command as shown in the following example:
Router# show interface cable 7/1/0 dynamic-service statistics
