Appendix E - Automatic Switching E-39
MN/22156, rev 12 Carrier Presence Switching
With the settings shown in the example above, this particular Remote will
attempt to occupy 9 Mbps in the available pool, but if bandwidth resources are
limited, the carrier will have no less than 64 kbps.
In the example shown in figure E-27, a single Remote has attempted to occupy
the 9 Mbps specified in an empty pool. However, because the pool capacity is
less than this amount, the system has allocated all available bandwidth to the
carrier.
Figure E-27 Single Remote example
In figure E-28, a second Remote has also requested a 9 Mbps carrier from the
same pool, and because this amount of bandwidth was not available, the system
provided an equal split of bandwidth between the two Remotes.
Figure E-28 Two Remotes example
Note: Equal divisions are only possible if all Remotes are provisioned with the
same rate policies, otherwise unequal splitting of bandwidth will occur for
carrier assignment.
The next example (figure E-29) shows available bandwidth or an absence of a
carrier where a Remote vessel has roamed away, leaving a vacancy within the
pool.
