DATA-CON (Network Control Driver)
The TN798 Processor circuit pack con tains the following objec ts: the SW-CTL
(Switch Control), four DATA-CHLs (Data Channels), the DATA-CON (Network
Control Driver), and the generic ha rdware 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 describ ed.
Together the 4 DATA-CHLs and the DATA-CON provide a data communications
interface that allows DTE equipment connec ted to port c ircuit packs to
communicate with software app lications running on the sys tem. The DATA-CON
represents the interface to the co ntrol channel of the TDM Bus. Each DATA-CHL
represents a dial-up/d ial-out asynchronous communic ation port that interfaces to
the TDM Bus. The DATA-CON supports the signaling required to establish and
tear down a connection b etween the terminal equipm ent and a software
application. Data is transp orted between the termi nal equipment and the
software over the connection estab lished over the DATA-CHL.
From an external (user) point of view, the DATA-CON is not directly accessible via
a system technician comman d; that is, there is no object c ommand word that
represents it. Instead, the DATA-CON is tested under the guise of the DATA-C HLs
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 log s, the Maintenance Name is DATA-CON.
