GUIDELINES ON LINE BAND, SOUND QUALITY AND DELAY TIME
NOTES:
1. The following conditions apply to the side delay time
values and required band:
(1) Line band: 1.5 Mbps; Voice compression not used—
Voice packet size: 128 bytes
(2) Line band: 1.5 Mbps; Voice compression used—
Voice packet size : 32 bytes
(3) A voice packet size of 1,024 bytes assumed for all
but the 1.5 Mbps Line band.
2. ‘‘Voice Packet Loss Recovery’’ is a processing
function when the voice packet cannot be received
owing to communications interference.
(1) Silence: Sections without voice packets are processed
as silence.
(2) Redundancy: Enables the voice to be normally output
for continuous losses of up to 8 packets.
(3) Retransmission: Enables the voice to be normally output
for continuous losses of up to 15 seconds.
3. ‘‘Required band’’ represents the bands required for
voice transmission.
When sending other data (such as serial data), the
transmission band is separately required.
