Gain Settings:
Here. you. can. select. the. priority. of. audio. codecs.. While.
establishing. a. call,. the. DlV-140. will. negotiate. the. highest.
priority.of.codec.acceptable.to.both.parties..The.administrator.
can.choose.from.four.codecs..G.711.Mu.and.G.711.A.provide.
the.best.voice.quality.but.consume.the.most.bandwidth..G.723.
consumes.less.bandwidth.with.some.compromise.on.quality..
G.729.is.a.compromise.between.both..It.uses.significantly.less.
bandwidth.as.compared.to.G.711.and.gives.better.quality.as.
compared.to.G.723.
The.Jitter.Buffer.monitors.network.conditions.and.implements.
a. delay. profiling. algorithm. that. provides. better. tracking. of.
adaptive.jitter.buffer.and.improves.voice.quality..The.jitter.buffer.
automatically. determines. the. network. jitter,. maintains. the.
desired.packet.loss.rate,.subject.to.the.limit.of.the.maximum.
allowed. jitter. delay.. These. parameters. can. be. configured.
here.
The.Jitter.Buffer.Delay.specifies.the.maximum.desired.jitter.
delay.in.milliseconds..Range:.0.to.500.milliseconds..Default:.
150.milliseconds.
Specifies.the.allowable.packet.loss.rate.in.0.1%.units..Range:.
0.to.50.(corresponding.to.0.1.%.to.5.0.%)..Default:.1.(0.1%).
The.volume.settings.at.various.levels.can.be.configured.here..
Here.Tx. field. specifies. stream. going. from. this. device. to. IP.
network. and. Rx. specifies. the. stream. coming. to. this. device.
from.the.IP.network.
VoIP:
Increase. this. value. to. digitally. amplify. the. signals..
Range:.-40.dB.to.15.dB..Default:.0.dB.
PSTN:
. Increase. this. value. to. amplify. the. signals. at. analog.
level..Range:.0.or.1.(corresponding.to.0.and.6.dB)..Default:.0.
Tone:
. Modify. this. value. to. set. the. volume. level. of. tones..
Range:.-20.dB.to.15.dB..Default:.-12.dB.
