User Manual
Parameter
CBR (Constant Bit Rate): This service is used for
•
applications that require a constant data rate. It is mostly
used for transferring uncompressed audio and video, e.g.
videoconferencing,
audio/video distribution (television, distance education, e-
shops), and retrieval (video-on demand, audio libraries).
When you select this value from the drop-down list, the
Peak Cell Rate field is displayed. Specify a required value
(in cells per second).
Non Realtime VBR (Non-Real-time Variable Bit Rate):
•
This service can be used for transferring data that have
critical response-time requirements, e.g. air ticket booking,
bank transactions, and process monitoring. When you select
this value from the drop-down list, the Peak cell rate,
Sustainable cell rate, and Maximum burst size fields
are displayed. Specify required values.
Realtime VBR (Real-time Variable Bit Rate): This service
•
is used for delay-sensitive applications such as real time
video. The Rt-VBR provides higher network flexibility than
the CBR service. When you select this value from the drop-
down list, the Peak cell rate, Sustainable cell rate, and
Maximum burst sze fields are displayed. Specify required
values.
