This indicates that the Program line has been established and it is connected to
the far end.
When establishing a connection over one or several wireless connections, the
unit will bond the bandwidth available from all available wireless data links
automatically, meaning that the user does not have to make a call for each data
link, but just only one for all of them. As it can be seen bellow, the connection
bar will show with a small circle in green what 3G/4G connections are properly
connected when it is on green color.

If the user attempts to establish a call and it does not go through, a brief
description of the reason will be shown on the connection bar:

III.7.1
Video Bit rate configuration
When establishing a connection over 3G/4G or bonding different IP interfaces,
the unit will try to use as much bandwidth as possible. Once the connection is
established, if one of the IP links becomes very unstable or unavailable for any
reason, the unit will detect it and transmit all data on the rest of interfaces
preventing data losses.
In networks like 3G/4G or XDSL lines where the capacity of the link is shared
between different users and/or the quality of the connection might depend on
many different factors that might make the capacity of network very unstable,
one of the most important parameters to configure is the bit rate. The more bit
rate the better the quality, but the more network capacity we need to transmit
the same video contents.
