d) Jitter Buffer Mode
¥ Define the buffer mode for the
jitter of the voice packet. If
Adaptive is selected, the buff-
ering size will be automatically
adjusted according to the sig-
nal delay. Adaptive Immedi-
ately is recommended.
1 (G.711) 0: Disable
1: adaptive during silence period only
2: adaptive immediately

2 - Reserved --- -
3 (G.729) 0: Disable
1: adaptive during silence period only
2: adaptive immediately

4 (G.723.1) 0: Disable
1: adaptive during silence period only
2: adaptive immediately

Jitter Buffer Min Delay
¥ Define the size for the Jitter
Buffer. The disconnected voice
may be reduced if the delay
size is large. The Min Delay
must be greater than or equal to
the VIF size.
1 (G.711) 1-145 (1 step 1ms) 20
2 - Reserved --- -
3 (G.729) 1-500 (1 step 1ms) 20
4 (G.723.1) 1-500 (1 step 1ms) 30
Jitter Buffer Normal Delay
¥ Define the size for the Jitter
Buffer. The disconnected voice
may be reduced if the delay
size is large. The Normal
Delay must be greater than or
equal to twice the VIF size.
1 (G.711) N1-145 (1 step 1ms)
[ N1=The value of G.711 Min delay ]
40
2 - Reserved --- -
3 (G.729) N2-500 (1 step 1ms)
[ N2=The value of G.729 Min delay ]
40
4 (G.723.1) N3-500 (1 step 1ms)
[ N3=The value of G.723.1 Min delay ]
60
Jitter Buffer Max Delay
¥ Define the size for the Jitter
Buffer. The disconnected voice
may be reduced if the delay
size is large. The Max Delay
must be greater than or equal to
four times the VIF size.
1 (G.711) M1-145 (1 step 1ms)
[ M1=The value of G.711 Nor delay ]
80
2 - Reserved --- -
3 (G.729) M2-500 (1 step 1ms)
[ M2=The value of G.729 Nor delay ]
80
4 (G.723.1) M3-500 (1 step 1ms)
[ M3=The value of G.723.1 Nor delay ]
90
Jitter Buffer Idle Noise Level
¥ Define the voice level of the
idel packet (idle noise level)
for VAD (Voice Activity
Detection) configuration or Jit-
ter Overflow (packet loss). It is
recommended to define the
minimum value.
1 (G.711) 0-2000 (1 step 1dBm) 0
2 - Reserved --- -
3 (G.729) 0-2000 (1 step 1dBm) 0
4 (G.723.1) 0-2000 (1 step 1dBm) 0
dBm Entries:
0 = -70.00
1 = -69.99
2 = -69.98
3 = -69.97
4 = -69.96
|
1997 = -50.03
1998 = -50.02
1999 = -50.01
2000 = -50.00
5 Fast Connection Mode
• Determine whether the addess should be sent in the
setup message reducing setup time (fast connect
mode).
1: Normal mode
2: Fast Connect mode
