For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
A multimedia terminal adapter (MTA) is used to deliver broadband Internet, data, and/or voice access jointly with telephony service to a subscriber's or customer's premises using a cable network infrastructure. An MTA is normally installed at the customer's or subscriber's premises, and it is coupled to a multiple system operator (MSO) using a hybrid fiber coax (HFC) access network.
An MTA is provisioned by the MSO for broadband Internet, data, and/or voice service. For more information on MTA provisioning, refer to
Beacham, et al. Standards Track [Page 2]
RFC 5098 PacketCable/IPCablecom NCS Signaling MIB February 2008
the PacketCable Provisioning Specification [PKT-SP-PROV] and [RFC4682]. MTA devices include one or more endpoints (e.g., telephone ports), which receive call signaling information to establish ring cadence, and codecs used for providing telephony service. For more information on call signaling, refer to the PacketCable Signaling Specification [PKT-SP-MGCP] and [RFC3435]. For more information on codecs refer to the PacketCable Audio/Video Codecs Specification [PKT-SP-CODEC].
Telephone systems are typically very complex and often have a wide distribution. It is therefore important for management systems to support MTAs from multiple vendors at the same time, including those from multiple countries. This MIB module provides objects suitable for managing signaling for MTA devices in the widest possible range of markets.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
The terms "MIB module" and "information module" are used interchangeably in this memo. As used here, both terms refer to any of the three types of information modules defined in Section 3 of RFC 2578 [RFC2578].
An MTA is a PacketCable or IPCablecom compliant device providing telephony services over a cable or hybrid system used to deliver video signals to a community. It contains an interface to endpoints, a network interface, codecs, and all signaling and encapsulation functions required for Voice-over IP transport, call signaling, and Quality of Service signaling. An MTA can be an embedded or standalone device. An Embedded MTA (E-MTA) is an MTA device containing an embedded Data Over Cable Service Interface Specifications (DOCSIS) Cable Modem. A Standalone MTA (S-MTA) is an MTA device separated from the DOCSIS Cable Modem by non-DOCSIS Media Access Control (MAC) interface (e.g., Ethernet, USB).
The L line package refers to the Media Gateway Control Protocol (MGCP) package for the core signaling functionality, as defined by PacketCable and IPCablecom. An MTA provides all L package elements: however, the operator determines their application.
The E line package refers to the MGCP package extensions, over and above the core L package, defined in support of international requirements. E line package elements are optional, vary from country to country, and are set by operator or regulatory requirements.
This MIB module provides a set of objects required for Multimedia Terminal Adapter (MTA) devices compliant with the PacketCable and IPCablecom signaling specifications published by CableLabs, the European Telecommunications Standards Institute (ETSI), and the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) IPCablecom compliant Multimedia Terminal Adapter (MTA) devices. The Signaling MIB module (PKTC-IETF-SIG-MIB) is intended to update various Signaling MIB modules from which it is partly derived:
- the PacketCable 1.0 Signaling MIB Specification [PKT-SP-MIB-SIG-1.0],
- the PacketCable 1.5 Signaling MIB Specification [PKT-SP-MIB-SIG-1.5],
- the ITU-T IPCablecom Signaling MIB requirements [ITU-T-J169],
- the ETSI Signaling MIB [ETSI-TS-101-909-9]. The ETSI Signaling MIB requirements also refer to various signal characteristics defined in [ETSI-TS-101-909-4], [ETSI-EN-300-001], [ETSI-EN-300-659-1], [ETSI-EN-300-324-1] and [ETSI-TR-101-183].
Several normative and informative references are used to help define Signaling MIB objects. As a convention, wherever PacketCable and IPCablecom requirements are equivalent, the PacketCable reference is used in the object REFERENCE clause. IPCablecom compliant MTA devices MUST use the equivalent IPCablecom references.
Beacham, et al. Standards Track [Page 4]
RFC 5098 PacketCable/IPCablecom NCS Signaling MIB February 2008
This MIB module describes the various Signaling MIB objects that are directly related to the PacketCable MTA and the endpoints supported on the MTA, each of which provides services independently. The recognition and distinction of the endpoints are made by utilizing the ifTable (IF-MIB [RFC2863]), where each index (ifIndex) value refers to a unique endpoint. This MIB module also utilizes the syntax definition of the Differentiated Services Code Point (DSCP) from DIFFSERV-DSCP-TC [RFC3289] for defining MIB objects that allow for differentiation between various types of traffic in the service provider network.
The following sections explain each part in further detail. It is to be noted that future enhancements to specify Notification Objects are also allowed (pktcSigNotification).
This is further divided into device-specific elements (pktcSigDevObjects) and endpoint-specific elements (pktcSigEndPntConfigObjects).
Some highlights of the device-specific elements are as follows:
pktcSigDevCodecTable - this object identifies the codec types available on the device.
pktcSigDevEchoCancellation - this object identifies the capability of echo cancellation on the device.
pktcSigDevSilenceSuppression - this object specifies if the device is capable of silence suppression (Voice Activity Detection).
pktcSigPulseSignalTable - this table selects the various signals used in the application of the metering pulse signal to the twisted pair line.
pktcSigDevToneTable - this table specifies a flexible structure within which to specify all of the tones used in the MTA.
Beacham, et al. Standards Track [Page 5]
RFC 5098 PacketCable/IPCablecom NCS Signaling MIB February 2008
pktcSigDevMultiFreqToneTable - this table defines the characteristics of tones with multiple frequencies. Each entry in this table represents the frequency reference of a multi-frequency tone.
The endpoint-specific elements are mostly confined to the Endpoint configuration MIB table (pktcSigEndPntConfigTable). This table describes the MTA endPoint configuration. The number of entries in this table represents the number of provisioned endpoints.
pktcSigDeviceGroup - this group contains all the MIB objects that apply on a per-device basis and need to be implemented by an MTA to claim compliance with the specified MIB module.
pktcSigEndpointGroup - this group contains all the MIB objects that apply on a per-endpoint basis and need to be implemented by an MTA to claim compliance with the specified MIB module.
pktcLLinePackageGroup - this group contains the MIB objects that need to be implemented to support the L line package.
pktcELinePackageGroup - this group contains the MIB objects that need to be implemented to support the E line package.
pktcInternationalGroup - this group contains optional MIB objects designed to support operations over the widest possible range of markets.

Beacham, et al. Standards Track [Page 69]
RFC 5098 PacketCable/IPCablecom NCS Signaling MIB February 2008
The single row of the pktcSigDevToneTable defines one multi-frequency group of five rows (ToneFreqCounter) defined in the pktcSigDevMultiFreqToneTable and instructs the MTA to play this group only once (non-repeatable as ToneRep-Count equals 0).
Example B - Congestion Tone - congestion(17):
Note: This example of an embedded cadence is based on an operator variation.
1) 400Hz on for 400ms -10 dBm
2) 400Hz off for 350ms
3) 400Hz on for 225ms -4 dBm
4) 400Hz off for 525ms
5) repeat (1) through (4) 5000 times or T0 time out (whichever is the shortest period)
The first row of the pktcSigDevToneTable table instructs the MTA to play one row (ToneFreqCounter) of the pktcSigDevMultiFreqToneTable table only once (non-repeatable as ToneRep-Count equals 0). The second row of the pktcSigDevToneTable table instructs the MTA to play the next two rows (ToneFreqCounter) of the pktcSigDevMultiFreqToneTable table and make this frequency group repeatable (ToneRep-Count is not 0).

RFC 5098 PacketCable/IPCablecom NCS Signaling MIB February 2008
There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations.
The following Differentiated Services Code Point (DSCP) and mask objects are used to differentiate between various types of traffic in the service provider network:
pktcSigDefCallSigDscp pktcSigDefMediaStreamDscp
These objects may contain information that may be sensitive from a business perspective. For example, they may represent a customer's service contract that a service provider chooses to apply to a customer's ingress or egress traffic. If these objects are SET maliciously, it may permit unmarked or inappropriately marked signaling and media traffic to enter the service provider network, resulting in unauthorized levels of service for customers.
The following objects determine ring cadence, repeatable characteristics, signal duration, and caller id subscriber line protocol for telephony operation:
If these objects are SET maliciously, it may result in unwanted operation, or a failure to obtain telephony service from client (MTA) devices.
Beacham, et al. Standards Track [Page 73]
RFC 5098 PacketCable/IPCablecom NCS Signaling MIB February 2008
The objects in the pktcSigEndPntConfigTable are used for endpoint signaling. The pktcSigEndPntConfigCallAgentId object contains the name of the call agent, which includes the call agent Fully Qualified Domain Name (FQDN). If this object is SET maliciously, the MTA will not be able to communicate with the call agent, resulting in a disruption of telephony service. The pktcSigEndPntConfigCallAgentUdpPort object identifies the UDP port for NCS traffic. If this object is SET maliciously, the call agent will not receive NCS traffic from the MTA, also resulting in a disruption of telephony service.
Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. The most sensitive is pktcSigEndPntStatusCallIpAddress within pktcSigEndPntConfigTable. This information itself may be valuable to would-be attackers. Other MIB Objects of similar sensitivity include pktcSigEndPntStatusError, which can provide useful information to MTA impersonators, and pktcSigDevCodecMax, which can provide useful information for planning Denial of Service (DoS) attacks on MTAs.
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPsec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.
It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
