2.2 ProgrammingProgramming Guide 19Parameter DescriptionsQoS Field SettingsThe parameters below are used to set the ToS (Type of Service) field in the header of IP packets to controlQoS of VoIP communications.For more information about QoS, refer to "A1.4 QoS (Quality of Service)" of the VoIP Gateway Card GettingStarted. For the actual setting values, consult your network administrator.Jitter buffer SettingsWhen voice signals are packetized and transmitted, individual packets can take different paths through thenetwork and arrive at the destination at varied timings. This is referred to as "jitter", and it can causedegradation in speech quality. To compensate for jitter problems, the "jitter buffer" accumulates the packetstemporarily for processing.The parameters below are used to adjust the size of the jitter buffer. However, in general, there is no need tochange the default values.Parameter & Description Default Value RangeToSSpecifies the value in the ToS field by a generic term.For details, refer to "Detailed Explanations".Priority: 0 0 to 7Normal Normal,Monetary Cost,Reliability,Throughput,DelayDSCPSpecifies the value in the ToS field by a DSCP for DiffServ.No default 0 to 63HEXSpecifies the value in the ToS field by a hexadecimal number.No default 00 to FFParameter Default Value RangeG.711/G.729A Jitter Buffer Minimum (ms) 10 10 × n (n = 1–40)G.711/G.729A Jitter Buffer Maximum (ms) 400 10 × n (n = 1–40)G.711/G.729A Jitter Buffer Default Value (ms) 10 10 × n (n = 1–40)G.711/G.729A Jitter Buffer Adjustment Interval (s) 1-5s5 1 to 5G.723.1 Jitter Buffer Minimum (ms) 30 30 × n (n = 1–40)G.723.1 Jitter Buffer Maximum (ms) 1200 30 × n (n = 1–40)G.723.1 Jitter Buffer Default value (ms) 30 30 × n (n = 1–40)G.723.1 Jitter Buffer Adjustment Interval (s) 1-5s 5 1 to 5
