" This object contains the Row Status associated with the

number of repetitions of the call waiting tone that the
MTA will play from a single CMS request. The MTA MUST NOT
update this object with the information provided in the
NCS message (if present). If the value of the object is

the MIB Object 'pktcSigEndPntConfigCallAgentId'. The
processes are outlined in the PacketCable NCS and Security
specifications, and MUST be followed by the MTA.
The IP address type contained in this MIB Object is

DESCRIPTION
" This object contains the error status for this interface.
The operational status indicates that all operations
necessary to put the line in service have occurred, and the
CMS has acknowledged the Restart In Progress (RSIP)
message successfully. If pktcMtaDevCmsIpsecCtrl is enabled
for the associated Call Agent, the noSecurityAssociation
status indicates that no Security Association (SA) yet
exists for this endpoint. If pktcMtaDevCmsIpsecCtrl is
disabled for the associated Call Agent, the
noSecurityAssociation status is not applicable and should
not be used by the MTA. The disconnected status indicates
one of the following two:
If pktcMtaDevCmsIpsecCtrl is disabled, then no security
association is involved with this endpoint. The NCS
signaling software is in process of establishing the NCS
signaling link via an RSIP exchange.

6. Examples
This section provides a couple of examples, specifically related
to the MIB tables pktcSigDevToneTable and
pktcSigDevMultiFreqToneTable.

PacketCable/IPCablecom NCS Signaling MIB August 2007
Example A: Call waiting tone defined per ITU-T E.180:
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:

pktcSigDevToneTable:

=============================================================
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

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.

pktcSigDevToneTable:
ToneType|ToneFreqGroup|ToneFreqCounter|ToneRep-Count|Steady
=============================================================
9 1 1 0 false(2)
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
Beacham/Kumar/Channabasappa Expires - January 2008 [Page 70]
PacketCable/IPCablecom NCS Signaling MIB August 2007
play next two rows (ToneFreqCounter) of the
pktcSigDevMultiFreqToneTable table and make this frequency group
repeatable (ToneRep-Count is not 0).

8. Security Considerations
Beacham/Kumar/Channabasappa Expires - January 2008 [Page 71]
PacketCable/IPCablecom NCS Signaling MIB August 2007
There are a number of management objects defined in this MIB that
have 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
pktcSigDevR4Cadence
pktcSigDevR5Cadence
pktcSigDevR6Cadence
pktcSigDevR7Cadence
pktcSigDevRgCadence
pktcSigDevRsCadence
pktcSigDevCidSigProtocol
pktcSigDevVmwiSigProtocol
pktcSigPulseSignalDuration
pktcSigPulseSignalPauseDuration
If these objects are SET maliciously, it may result in unwanted
operation, or a failure to obtain telephony service from client
(MTA) devices.
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
Beacham/Kumar/Channabasappa Expires - January 2008 [Page 72]
PacketCable/IPCablecom NCS Signaling MIB August 2007
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.
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.
9. IANA Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER Value
---------- -----------------------
pktcSigMib { mib-2 XXX }
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for XXX under the mib-2 subtree and to
record the assignment in the SMI Numbers registry. When the
assignment has been made, the RFC Editor is asked to replace XXX

(here and in the MIB module) with the assigned value and to remove
this note.
