DATA-CON (Network Control Driver)
The TN798 Processor circuit pack contains the following objects: the SW-CTL 
(Switch Control), four DATA-CHLs (Data Channels), the DATA-CON (Network 
Control Driver), and the generic hardware that interfaces with the TDM Bus 
(DATA-BD). The DATA-CON (Network Control Driver) is the subject of this section. 
The DATA-CHLs (Network Control Channels) are also described.
Together the 4 DATA-CHLs and the DATA-CON provide a data communications 
interface that allows DTE equipment connected to port circuit packs to 
communicate with software applications running on the system. The DATA-CON 
represents the interface to the control channel of the TDM Bus. Each DATA-CHL 
represents a dial-up/dial-out asynchronous communication port that interfaces to 
the TDM Bus. The DATA-CON supports the signaling required to establish and 
tear down a connection between the terminal equipment and a software 
application. Data is transported between the terminal equipment and the 
software over the connection established over the DATA-CHL. 
From an external (user) point of view, the DATA-CON is not directly accessible via 
a system technician command; that is, there is no object command word that 
represents it. Instead, the DATA-CON is tested under the guise of the DATA-CHLs 
that it controls. The 
test data-module <ext> [short | long]
 command tests the 
DATA-CON along with the DATA-CHL designated by <ext> but all Test Results 
are associated with the DATA-CHL Maintenance Name.
From an internal (system software) point of view, the DATA-CON uses the same 
set of tests as the DATA-CHLs. Therefore, the DATA-CON assumes the same 
Error Type and Aux Data values as the DATA-CHLs in the Hardware Error Log. It 
is also alarmed at the same Alarm Level (that is, MINOR, ON BOARD) in the 
Alarm Log. In both logs, the Maintenance Name is DATA-CON.
