State
Description
Session Open
Synchronization and session negotiation have been performed. Applications are assigned
to streams and all connection parameters are negotiated. A session can be active for a
very long time without any further activity.
Paging
A transitory state indicating that the R&S
CMW attempts a connection but no traffic chan-
nel is active yet ("Session Open" --> "Connected"; not shown in the figure below).
Connected
The traffic channel is active and available for the applications that have been assigned to
a stream. All applications are "connected" at the same time.
The R&S
CMW can still vary connection parameters, perform transmitter and receiver
tests, or initiate a dual-band handoff.
Control commands initiated by the R&S
CMW or by the AT switch between the con-
nection states. The following figure shows possible state transitions. Dashed lines cor-
respond to actions initiated by the AT, dotted lines to the ON | OFF key (sector state),
solid lines to the connection control hotkeys (AT state).
