            pktcEnNcsMinimumDtmfPlayout is set to 40ms then

     DESCRIPTION

     "This MIB Object allows the Service Provider to choose
     a suitable policy for Loop Voltage behavior on MTAs.  

     Unless overridden by the operator, the MTA MUST use the
     default value specified in the definition of this MIB
     Object.

     The MTA MUST adhere to PacketCable signaling 
     requirements, such as the NCS open loop voltage requirement, 
     irrespective of any chosen policy. 

     For MTAs that need to remove loop voltage during the MTA 
     initialization phase, in contradiction to a chosen policy,
     such a loop voltage removal period MUST NOT exceed 1000ms.


     The MTA MUST  retain the value of this MIB Object across 
     hard reboots or soft resets (for a definition of the terms,
     please refer to [1]).

     This MIB object specifies four policies. An informative
     illustration of the E-MTA behavior with different policies
     is presented in Appendix A. 


     Provisioned line is an MTA Endpoint that has been provided 
     with valid per-line configuration data either via the 
     configuration file (during provisioning) or the SNMP 
     management interface.

     When the MIB Object is set to a value of 
     voltage_at_all_times(1),  - indicating Policy 1 -
     the MTA MUST maintain the loop idle voltage on all 
     lines, irrespective of the line status.

     
     When this MIB Object is set to a value of 
     voltage_unless_RF_QAM_absent(2)- indicating Policy 2 
     - the MTA MUST apply loop idle voltage at all 
     times except when it confirms the absence of any 
     RF QAM carrier, following a complete scan of the 
     spectrum (i.e., loop voltage is maintained during
     the scan). When the MTA detects the presence of any 
     RF QAM carrier, it MUST apply the loop idle voltage. 
     Additionally, the following conditions apply:
       - during a hard reboot, this policy applies at all 
         lines until the MTA is successfully provisioned (
         i.e., pktcMtaDevProvisioningState has a value 
         other than 'inProgress')
       - once the MTA is successfully provisioned (
         (i.e., pktcMtaDevProvisioningState has a value 
         of 'pass(1)', 'passWithWarnings(4)' or 
         'passWithIncompleteParsing(5)') then the policy
         applies to all provisioned lines 
       - upon the onset of a re-initialization due to a 
         soft reset (via SNMP or Rf conditions) the MTA MUST 
         continue to maintain the existing policy and state 
         on previously provisioned lines, unless overridden 
         by a policy or the provisioning process specifies
         otherwise

     This policy is similar to Policy 1, except for the 
     ability to recognize events like cable cuts (due to 
     malicious activities, or otherwise).


     The following requirements apply to policies 3 and 4:
     - upon the onset of a re-initialization due to a soft reset 
       the MTA MUST continue to maintain the existing policy and 
       state on provisioned lines, unless overridden by a policy 
       or the provisioning process specifies otherwise
     - once the provisioning process is completed with the value 
       of the MIB Object pktcMtaDevProvisioningState set to a 
       value of 'pass(1)', 'passWithWarnings(4)' or 
       'passWithIncompleteParsing(5)', the MTA MUST apply the
       chosen policy to all the provisioned lines

     When this MIB Object is set to a value of 
     voltage_based_on_service_or_timers(3)- indicating Policy 3 - 
     the MTA MUST adhere to the requirements that follow 
     at any given point in time: 

          -  when the timer defined by 
            pktcEnNcsEndPntLVMgmtResetTimer has 
             a non-zero value, the MTA MUST apply loop idle voltage 
             under all circumstances (similar to policy 1).
             Refer to the definition of the MIB Object for the
             persistence and timer requirements.

          -  when the timer defined by 
             pktcEnNcsEndPntLVMgmtMaintTimer has 
             a non-zero value, the MTA MUST maintain a line's loop 
             idle voltage state that was in effect prior to the timer 
             being set to a non-zero value. Refer to the definition 
             of the MIB Object defining the timer for the persistence 
             and timer requirements.

          - When the timers defined by 
            pktcEnNcsEndPntLVMgmtMaintTimer and 
            pktcEnNcsEndPntLVMgmtResetTimer have 
            expired (both have a value of zero), then:
             = the MTA MUST apply loop voltage if the provisioning 
               process is completed with the value of 
               pktcMtaDevProvisioningState set to a value of 
               than 'pass(1)', 'passWithWarnings(4)' or 
               'passWithIncompleteParsing(5)' 
             = During a T4 timeout (note: the timers have expired), 
               the E-MTA MUST remove loop idle voltage on all lines

          -  When both the timers are active (i.e., they both have 
             non-zero values), then the timer defined by the MIB 
             Object pktcEnNcsEndPntLVMgmtMaintTimer takes precedence

          -  if none of the above cases apply, the MTA MUST remove 
             loop idle voltage on all lines
                     
     When the MIB Object is set to a value of 
     voltage_based_on_service(4) - indicating Policy 4 - the 
     following conditions apply at any given point in time:

         - the MTA MUST apply loop idle voltage to all 
         the provisioned lines if the value of the MIB Object 
         'pktcMtaDevProvisioningState' is set to a 
         value of 'pass(1)', 'passWithWarnings(4)' 
         or 'passWithIncompleteParsing(5)' 

         - in all other cases, the MTA 
         MUST remove loop idle voltage on all lines."
