4. Select the Traffic class from the drop-down list.
You may select subscribed or one of the following:
• Conversational is real-time two-way conversation. It is primarily used
for voice over IP and video conferencing.
• Streaming is real-time one-way communication. It is primarily used for
video and audio.
• Interactive is two-way communication (not real-time). It is used for
communication that is not very delay-sensitive, such as web browsing,
database retrieval and server access. Examples of machines interaction
with remote equipment are: polling for measurement records and
automatic database enquiries (tele-machines).
• Background is used for data which is not delay-sensitive, such as E-
mail, SMS, download of databases and reception of measurement
records.
5. Type in the bit rates in kbps in the following fields:
• Maximum bit rate ul (kbps) is the maximum upload bit rate allowed for
this profile.
• Maximum bit rate dl (kbps) is the maximum download bit rate allowed
for this profile.
• Guaranteed bit rate ul (kbps) is the guaranteed upload bit rate needed
for this profile.
• Guaranteed bit rate dl (kbps) is the guaranteed download bit rate
needed for this profile.
Important
For best performance, choose the right traffic class for your
application. In general, Standard IP (Background) is best
suited for TCP/IP applications, and Streaming IP is best
suited for UDP traffic, e.g. live video or audio.
Note
For SAILOR 250 FleetBroadband the maximum allowed bit rate is
128 kbps.
Note
When you click Apply, the bit rate values you typed in may be
rounded off because only certain values are allowed.
