comVoiceDsp 1.3.6.1.4.1.5504.6.12
Voice DSP MIB for Voice Application Specific Processing cards.
MODULE-IDENTITY    

zhoneVoiceDsp 1.3.6.1.4.1.5504.4.3.3
The MIB module to describe managed objects for Zhone's voice DSP applications. The Voice DSP MIB has the following components: * voiceDspDefaultConfiguration * voiceDspStatusTable * channelStatusTable * voiceDspTraps
Status: current Access: read-only
OBJECT-IDENTITY    

voiceDspDefaultConfiguration 1.3.6.1.4.1.5504.4.3.3.1
System-wide defaults for voice DSP variables. These values will be used by voice DSP to set up default values to be used per call.
Status: current Access: read-only
OBJECT-IDENTITY    

redundancyOverSubscriptionType 1.3.6.1.4.1.5504.4.3.3.1.1
voice DSP redundancy over-subscription model. It is important to know the concept of active versus standby resources in order to understand how over- subscription works. For each call that is made on our equipment, resources are used. A resource is active if it is currently in use and it is standby if it is being held in case of the active's failure. If an active resourse fails, the standby can take over and the call continues. On the standby resources in a redundancy configuration can be oversubscribed. A service provider system administrator can configure a voice DSP system to use one of the following oversubscription models: * none: implies 1:1 (one to one) oversubscription. When a standby is allocated, the pool of available actives is depleted by one. * low: implies 1:2 oversubscription. * medium: implies 1:4 oversubscription. * high: implies infinite oversubscription. Active pool is never depleted when any standbys are allocated. If all active resources are used for real calls, no standby resources will be available to take over a failed call. The default value of this variable is high. This variable is supported only on BAN with VASP card(s).

OBJECT-TYPE    
  INTEGER none(1), low(2), medium(3), high(4)  

jitterBufferType 1.3.6.1.4.1.5504.4.3.3.1.2
Voice DSP channel jitter buffer defaults. There are two types of jitter algorithms: static and dynamic. Dynamic allows the jitter buffer to grow and shrink as inter-arrival jitter changes. A static jitter buffer does not. Some examples of the voice connection types used for; Voice Over ATM (VoATM): pots-to-aal2, isdn-to-aal2, aal2-to-gr303, aal2-to-v52. Voice Over IP (VoIP) : sip-to-ds1, sip-to-gr303, sip-to-v52. Dynamic jitter buffer is not supported in VoATM case. Default jitter buffer type is static for VoATM, and dynamic for VoIP.
Status: current Access: read-write
OBJECT-TYPE    
  INTEGER static(1), dynamic(2)  

jitterBufferSize 1.3.6.1.4.1.5504.4.3.3.1.3
Voice DSP jitter buffer size in milliseconds. More specifically, it refers to the amount of memory usage that can store certain milliseconds of voice. There are two types of jitter algorithms: static and dynamic. Dynamic allows the jitter buffer to grow and shrink as inter-arrival jitter changes. A static jitter buffer does not. When the jitterBufferType is dynamic, jitterBufferSize is the initial buffer size the jitter buffer can grow to. Some examples of the voice connection types used for; Voice Over ATM (VoATM): pots-to-aal2, isdn-to-aal2, aal2-to-gr303, aal2-to-v52. Voice Over IP (VoIP) : sip-to-ds1, sip-to-gr303, sip-to-v52. Valid range is 1 to 33 milliseconds for VoATM case. Valid range is 1 to 100 milliseconds for VoIP case. Default jitter buffer size is 10 milliseconds.

interArrvJitThreshold 1.3.6.1.4.1.5504.4.3.3.1.4
The inter-arrival jitter threshold per channel used as a trigger value in milliseconds to generate a trap when its value is passed. If this value is 0, the threshold mointoring is disabled for inter-arrival jitter. Valid range is 0 to 100 milliseconds. The default value is 80 milliseconds. This variable is not supported.

pktsLostThreshold 1.3.6.1.4.1.5504.4.3.3.1.5
Voice DSP channel packets lost per minute threshold. A trap will be generated when this value is passed. If this value is 0, the threshold mointoring is disabled for packets lost. Valid range for this value is from 0 to 10000 pkts/ min. The default value is 600 pkts/min. This variable is not supported.

echoCancellationType 1.3.6.1.4.1.5504.4.3.3.1.6
This data informs which echo cancellation algorithm to be used by default: 165 or 168 for a particular channel. The numbers 165 and 168 are the ITU designations for the algorithms. The number following the designation describes the echo tail length in milliseconds. Both G.165 and G.168 are ITU-T recommendations. G.168 has slightly stricter technical specs. G.168 defines much better how the tests are performed. If an echo canceller passes the G.165 spec, then it is G.165 compliant. If it passes G.168, it is both G.168 and G.165 compliant. The echo tail length required depends on factors such as network configuration, local loop length, line frequency response, etc. Generally, 16 ms is more than adequate for local loop (ie. Zedge) and 32 ms is a good minimum for Network side. Our products currently support up to 48 ms of echo tail length, MALC supports 16 ms of echo tail length. Valid values for the variable are: * off - echo cancellation is off (on all platforms). * g165EchoTL16 - G.165 echo cancellation with echo tail length of 16ms (on MALC only). * g168EchoTL48 - G.168 echo cancellation with echo tail length of 48ms (on the other platforms, i.e.: BAN, Sechtor 100, Z-Edge64). Following values are not supported: * g165EchoTL32 - G.165 echo cancellation with echo tail length of 32ms. * g165EchoTL48 - G.165 echo cancellation with echo tail length of 48ms. * g168EchoTL32 - G.168 echo cancellation with echo tail length of 32ms. * g168EchoTL64 - G.168 echo cancellation with echo tail length of 64ms. * g168EchoTL80 - G.168 echo cancellation with echo tail length of 80ms. * g168EchoTL96 - G.168 echo cancellation with echo tail length of 96ms. * g168EchoTL112 - G.168 echo cancellation with echo tail length of 112ms. * g168EchoTL128 - G.168 echo cancellation with echo tail length of 128ms. The default value is g165EchoTL16 for MALC, and g168EchoTL48 for the other platforms.

silenceSuppressionType 1.3.6.1.4.1.5504.4.3.3.1.7
This data informs a voice DSP what type of silence suppression algorithm to use on a channel. Silence suppression is used to suppress packet generation during periods of silence of a voice call. The SID (silence descriptor) frame is generated at the start of a silence period, or periodically, and it is used to characterize the power level of the background noise during silence period on the encode side of the voice path. The SID frame is then passed to the decode side through the packet encoding medium (AAL2 or RTP). The decode side then generates comfort noise at an equivalent power level dictated by the SID frame values. Valid values for the variable are: * silSupOff - silence suppression is off. * silSupOnSidOn - send an SID frame at a specified constant interval (e.g. 100ms). Following values are not supported: * silSupOnSidOff - discontinue transmission during silence periods and no SID frame is sent. * silSupOnSidConst - send an initial SID frame and then discontinue transmission. Silence suppression is not supported on MALC. The default value is silSupOff.
