mscVsFramerSilenceSuppression

Module: Nortel-MsCarrier-MscPassport-VoiceMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-VoiceMIB::mscVsFramerSilenceSuppression

OID (numeric): 1.3.6.1.4.1.562.36.2.1.80.2.12.1.6

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute specifies when ingress silence suppression is desired during voice traffic.

If silenceSuppression is off, silence suppression is never desired. If silenceSuppression is on, silence suppression is always desired. If silenceSuppression is congested, silence suppression is desired only when the network is congested. If silenceSuppression is slow, silence suppression is desired only after 20 seconds without audio. If silenceSuppression is slowAndCongested, both the slow and congested options are desired. If silenceSuppression is casIdleCode, the silence suppression is only desired when the idleCode is active for 20 to 40 seconds. casSignalling must be set to interpret if silenceSuppression is set to casIdleCode. silenceSuppression can be set to casIdleCode only if this VoiceService is running on a DS1V, E1V, 1pDS1V, 1pE1V or J2MV card.

The negotiated ingress silence suppression is available in negotiatedIgSilenceSuppression.

If the silenceSuppressor or vtds feature is present, silenceSuppression defaults to on. Otherwise, silenceSuppression defaults to off.

What is mscVsFramerSilenceSuppression?

Controls when ingress silence suppression kicks in for voice traffic: off, on (always), congested (only under network congestion), slow (after 20s of no audio), slowAndCongested (both), or casIdleCode (only while the CAS idle code is active); this is the bandwidth-saving knob for quiet call segments.
