4.2.3. gc_GetNetworkH( )

The gc_GetNetworkH( ) function can be used to retrieve the network device handle associated with the line device. For circuits located on an Intel® Dialogic network interface board (DTI), the returned handle can then be used when invoking Dialogic DTI functions.For circuits located on an Intel® NetStructure™ SS7 board, the returned handle will be the same as the specified line device. This handle cannot be used with DTI functions.

Typical usage of this function was to perform routing of a Global Call line device (dt_listen( ), dt_getxmitslot( )). However, this call control library supports the Global Call functions (gc_Listen( ), gc_GetXmitSlot( )) that can be used regardless of the type of network interface device (DTI or SS7). Therefore, for routing of SS7 line devices, it is recommended to always use the Global Call functions instead of the DTI functions. This makes the network device type transparent to the application.

See Section 5.4, Routing later in this document for more on routing.
