T
This section describes the DAL interface for a generic time switch device driver such as a SBS or
a SBSLITE device. The module and device management block, Interface/Clock, Status/Counts
and Diagnostics blocks are standard blocks that encapsulate that of a typical PMC device driver.
The LVDS controller, In-band link Controller, and the Switch configuration blocks are logical
blocks that are specific to a typical time switch device.
Module and Device Management
The module and device management block connects with that of the underlying driver.
Opening the Space Switch Driver Module: dalNbcsTswModuleOpen
Performs module level initialization of the time switch device driver by calling the underlying
module open function provided by the time switch driver. This usually involves allocating all of
the memory required by the driver and initializing the internal structures.
Closing the Space Switch Driver Module: dalNbcsTswModuleClose
Performs module level shutdown of the time switch driver. This involves deleting all devices
being controlled by the driver and freeing all the memory allocated by the driver.
