the provisioned endpoints provisioned with the information

communication with the CMS. Each endpoint can be assigned
to its own CMS. If the specific endpoint does not have
the corresponding CMS information in this table, the

pktcMtaDevCmsFqdn is defined in the PacketCable MIBMTA

use the current value of this object to communicate with
the corresponding CMS. The MTA MUST update this object
with the value of the 'Notified Entity' parameter of the
NCS message. Because of the high importance of this object
to the ability of the MTA to maintain reliable NCS

'Notified Entity' parameter of the NCS message. If the
Notified Entity parameter does not contain a CallAgent
port, the MTA MUST update this object with the default

object to the ability of the MTA to maintain reliable NCS
communication with the CMS, it is highly recommended not

6. Examples
This section provides a couple of examples, specifically related to
the MIB tables pktcSigDevToneTable and pktcSigDevMultiFreqToneTable.
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: pktcSigDevMultiFreqToneTable: ToneType|F-1|F-2|F-3|F-4|F-Mode|ModePrtg|DbL|OnDur|OffDur|Rep-Count =================================================================== 18 400 16 0 0 1 90 -40 500 400 0 18 400 0 0 0 2 0 -40 50 450 0 18 400 0 0 0 2 0 -40 50 3450 0 18 400 0 0 0 2 0 -40 50 450 0 18 400 0 0 0 2 0 -40 50 3450 0 pktcSigDevToneTable: ToneType|ToneFreqGroup|ToneFreqCounter|ToneRep-Count|Steady ============================================================= 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) pktcSigDevMultiFreqToneTable: ToneType|F-1|F-2|F-3|F-4|F-Mode|ModePrtg|DbL|OnDur|OffDur|Rep-Count =================================================================== 17 400 0 0 0 2 0 -100 400 350 0 17 400 0 0 0 2 0 -40 225 525 0 pktcSigDevToneTable: ToneType|ToneFreqGroup|ToneFreqCounter|ToneRep-Count|Steady ============================================================= 17 1 2 5000 false(2)
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 pktcSigDevMultiFreqToneTable: ToneType|F-1|F-2|F-3|F-4|F-Mode|ModePrtg|DbL|OnDur|OffDur|Rep-Count =================================================================== 9 1 400 16 0 0 1 85 -25 500 1000 0 9 2 400 0 0 0 2 0 -25 50 450 0 9 3 400 0 0 0 2 0 -25 50 3450 0 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 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 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 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.
