Enter the Voice Packet Configuration Table Number(1-256)
Possible values: 1~128 (CTX100 & CTX670 Basic)
1~256 (CTX670 Exp.)
01 Voice Packet Trans. Int. Voice Packet Transmission Interval:
This depends on the encoding method G711 or G729A. The default setting
are G711: 20ms, G729A: 40ms. 10ms is only used to test. So don’t use
10ms.
If LAN bandwidth is not enough for these parameters and the problem is
resolved to extend the interval according to the LAN requirement, you can
change to G711:40ms and G729a: 80ms. Note: 30ms need not be used.
Possible values: 10 msec (available for testing only up to release
200MF008), 20 msec (default), 30 msec, 40 msec or
80 msec
02 Jitter Buffer Type You can leave this field with its default or you can change the jitter buffer
type of DSP on BIPU.
Possible values: Fixed, Sequential, or Adaptive (default)
03 Jitter Buffer Length You can leave this field with its default or you can change the jitter buffer
lenght of DSP on BIPU.
Possible values: 0~250
04 Max. Acceptable Delay Not available in Release 2.0.
05 Measurement Period Not available in Release 2.0.
06 Packet Loss Ratio Not available in Release 2.0.
07 Packet Loss Threshold If packet loss is more than 10, an error is recorded in the CTX error log and
