UBR with PCR
(Unspecified Bit Rate with Peak Cell Rate): The UBR service is used
for applications that allow various delays and losses of packets. The
Peak Cell Rate is a determining factor in how often cells are sent in
an effort to minimize lag or jitter caused by traffic inconsistencies.
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).
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, interactive audio
(telephony), 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 size fields are displayed. Specify
required values.
If the service used by your additional equipment is provided via a
VLAN channel with a tag (VLAN ID), specify the needed value.
A priority tag for the type of traffic transmitted.
Move the switch to the right to enable the connection.
Move the switch to the left to disable the connection.
