xgcpLowerBoundForLatency
Module: XGCP-MIB
OID (symbolic): XGCP-MIB::xgcpLowerBoundForLatency
OID (numeric): 1.3.6.1.3.90.1.4.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object is the higher bound for Quality Alert for latency.
QA latency is an estimate of the network delay, expressed in milliseconds. This is the average value of the difference between the Network Time Protocol (NTP) timestamp indicated by the senders of the RTCP messages and the NTP timestamp of the receivers, measured when these messages are received.
When latency (milliseconds) is long enough to reach lower bound (e.g.150 ) and then higher bound(e.g. 300) the first time, a MGCP/SGCP Notify message is sent to the Media Gateway Controller.
Subsequent hits of the higher bound results in a MGCP/SGCP Notify message being sent to the Media Gateway Controller only after the lower bound is hit.
The default value of this object is 150.
What is xgcpLowerBoundForLatency?
The lower latency threshold, in milliseconds (125-200, default 150), used for voice-quality alerting, based on the average NTP timestamp difference measured from RTCP sender/receiver reports; a Notify fires the first time latency climbs from this bound up through the higher bound (xgcpHigherBoundForLatency), then again only after dipping back below this lower bound.
