6.7 Connection Management
6.7.1 Connection Configuration
The connection handler is responsible for the setup of cross
connections in the system and for the coordination of all related
activities carried out by the HHs. The following four operations can be
performed when dealing with cross connections, as shown in Figure
6-9:
•
Reserve
the needed resources for the cross connection are reserved, so that
they are allocated to the connection itself, even if this has not yet
been established.
•
Connect
the previously reserved resources are used for the establishment
of the connection.
•
Disconnect
the connection is removed, but the resources are retained.
•
Release
the resources for a connection are freed.

Figure 6-9 Cross Connection Activities
The connection handler receives requests to perform these actions
from the MRS, which in turn is requested to do so by the EM.
The connection handler communicates with all involved subsystems
(HHs) in order to set up a given cross connection. Thus, for example,
when setting up a connection from the ET to an AT in the
MINI-LINK BAS, the connection handler will have to communicate
with the cellmux and HHs.
All information about cross connections is stored in a database
maintained by the connection handler.
