Guidelines on Line Band, Sound Quality and Delay Time
NOTES:
Note 1: Voice packet size
Voice packet size other than for “Line band of 1.5 Mbps or
higher” is for data of 1024 bytes.
Voice packet size for “Line band of 1.5 Mbps or higher” is for
data of 256 bytes (PCM)/32 bytes (Sub-Band ADPCM) data.
Note 2: Voice Packet Loss Recovery
Voice Packet Loss Recovery is a processing method when
a voice packet cannot be received due to communication
interference.
Silence: Method of processing lost sectors as silence.
Redundancy: Method of accurately outputting continuous
losses of up to 8 packets.
Resend: Method of accurately outputting continuous
losses of up to 15 seconds.
Note 3: Required band
Required band represents the frequency band required for
voice transmission. When it is necessary to transmit serial
data, a transmission band is separately required.
