Startup & configuration
Three configuration parameters are used to detach/attach and control the suspend
mode. They are shown in the table below.
Actual CS/PS attach status can be read with the parameters in section 6.7.7 on page 6-
42. See also section 11.5.2 on page 11-13 for further description of suspend mode and
limitations when using it with SDM sleep.
6.6.12 Buffering on streaming connections
The IAI-2 stack in the BGAN XL Radio Module contains logic for buffering data until it
can be sent on-air. For end customers using a terminal for video streaming it may give
better performance (less jitter) if data is discarded instead of being buffered.
The .reduced_buffering parameter can be used to reduce the buffering.
Multi-Voice has special requirements and this can be controlled as described in 7.6.3.2
on page 7-21.
6.6.13 HDR bit rate ramp up
When a PDP context using an HDR service (e.g. HDR Full Symmetric) is started it may
take up to 15 seconds before the BGAN RAN allocates the full bit rate in the return
direction. The initial bit rate will start at a lower level and first be increased as the
terminal sends user data in the return direction.
If the terminal is used by broadcasters for streaming video, it may work better with the
customer’s video codec if the bit rate ramp up is faster. The faster bit rate ramp up can
be enabled with .hdr.rate_ramp_up.
