Recovery Delay
The KX-TDA0480 Recovery Delay feature controls a secondary Jitter buffer that is activated
dynamically when enabled. This feature allows the unit to recover from network delays by
temporarily storing voice data in a Jitter (recovery) buffer. In the event of a network delay, the
stored voice data is transmitted, assuring an uninterrupted conversation.
Several configuration parameters can be configured for this feature.
Maximum Receive Buffer Size (RX_BUFFER)
Record the maximum allowable size of the Jitter buffer. In most cases, the default size (1920
ms) will provide the best results.
Start Recovery (RX_BUFFER)
Record, in units of ms, the delay time threshold value for the start of recovery delay
processing
End Recovery (RX_BUFFER)
Record, in units of ms, the delay time threshold value for stopping the recovery delay
processing which started at the time specified as Start Recovery data. In most cases, the default
value (30 ms) will provide the best results.
Other
Cause of Fan Fault (FAN_FLT)
This parameter is irrelevant to the setting of the KX-TDA0480.
A-law/m-law Flag (LAW_FLAG)
Assign as appropriate to the network Codec set at the PBX.
The default setting for this field is m-law.
Recovery Delay Processing is defined as the operation of discarding soundless voice packets from the jitter buffer.
