1.  The Internet-Standard Management Framework

   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].

2.  Introduction

   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]
^L
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.

3.  Terminology

   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].

3.1.  MTA

   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).

3.2.  Endpoint

   An endpoint or MTA endpoint is a standard telephony physical port
   located on the MTA and used for attaching the telephone device to
   the MTA.

RFC 5098        PacketCable/IPCablecom NCS Signaling MIB   February 2008


3.3.  L Line Package

   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.

3.4.  E Line Package

   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.

4.  Overview

   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.

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.

4.1.  Structure of the MIB

   This MIB module is identified by pktcIetfSigMib and is structured
   into two major parts:

   - Signaling information that controls device and endpoint
     configuration (pktcSigMibObjects)

   - Module Conformance information(pktcSigConformance)

   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).

4.2.  pktcSigMibObjects

   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.

^L
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.

4.3.  pktcSigConformance

   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.

          cadences, including repeatability characteristics.  All
          fields in this object MUST be encoded in network-byte
          order.

          The first three higher-order octets are reserved.  The
          octets that follow are used to encode a 'bit-string', with
          each bit corresponding to 50 milliseconds.  A bit value of
          '1' indicates the presence of a ring-tone, and a bit value
          of '0' indicates the absence of a ring-tone, for that
          duration (50 ms) (Note: A minimum number of octets
          required to encode the bit-string MUST be used).

          The first two of the reserved octets MUST indicate the
          length of the encoded cadence (in bits) and MUST range
          between 1 and 264.  (Note: The length in bits MUST also be
          consistent with the number of octets that encode the
          cadence).  The MTA MUST ignore any unused bits in the last
          octet, but MUST reflect the value as provided on
          subsequent SNMP GETs.

          The third of the reserved octets indicates 'repeatability'
          and MUST be either 0x80 or 0x00 -- the former value
          indicating 'non-repeatability', and the latter indicating
          'repeatability'.

          The MTA MUST reject attempts to set a value that violates
          any of the above requirements."

          frequency is the frequency at which the sinusoidal voltage
          must travel down the twisted pair to make terminal
          equipment ring.  Different countries define different
          electrical characteristics to make terminal equipment
          ring.

          The f20Hz setting corresponds to a power ring frequency
          of 20 Hertz.  The f25Hz setting corresponds to a power ring
          frequency of 25 Hertz.  The f33Point33Hz setting
          corresponds to a power ring frequency of 33.33 Hertz.  The
          f50Hz setting corresponds to a power ring frequency of 50
          Hertz.  The f15Hz setting corresponds to a power ring
          frequency of 15 Hertz.  The f16Hz setting corresponds to a
          power ring frequency of 16 Hertz.  The f22Hz setting

   1) 400 Hz AM modulated by 16 Hz, on for 500ms at -4 dBm
   2) 400 Hz AM modulated by 16 Hz, off for 400ms
   3) 400 Hz not AM modulated, on for 50 ms at -4 dBm
   4) 400 Hz not AM modulated, off for 450 ms
   5) 400 Hz not AM modulated, on for 50 ms at -4 dBm
   6) 400 Hz not AM modulated, off for 3450 ms
   7) 400 Hz not AM modulated, on for 50 ms at -4 dBm
   8) 400 Hz not AM modulated, off for 450 ms
   9) 400 Hz not AM modulated, on for 50 ms at -4 dBm
   10) 400 Hz not AM modulated, off for 3450 ms
   11) not repeated, not continuous

   Assume userDefined1(18) is assigned to this tone:

   18          1             5              0       false(2)

   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)

   Example C - Call Waiting Tone - callWaiting1(9):

   1) 16 Hz is modulated to carry the 400 Hz signal, ModulationRate
   within 85%, on for 500msec, at -25 dBm or more but less than -14 dBm

   2) 16 Hz is modulated to carry the 400 Hz signal, off for 0 ~ 4 secs

   3) 400 Hz not modulated, on for 50 ms at -25 dBm or more but less
   than -14 dBm

   4) 400 Hz not modulated, off for 450ms

   5) 400 Hz not modulated, on for 50 ms at -25 dBm or more but less
   than -14 dBm

   6) 400 Hz not modulated, off for 3450ms ([4000 - (50+450+50)])

   7) Steps 3 thru 6 are repeated

   9           2             2              1       false(2)

   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).

8.  Security Considerations

   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:

        pktcSigDevR0Cadence
        pktcSigDevR1Cadence
        pktcSigDevR2Cadence
        pktcSigDevR3Cadence

   devices.

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.
