 NT7D16 Data Access card

Note: If this feature is active, and the port is connected to a DTE that 
holds DTR OFF when idle, the port will be permanently busied out to 
inbound calls following the DTR timeout period.

Once a successful data call is completed, the user's activity is monitored. If 
no activity occurs within the amount of time configured in the downloaded 
parameters, the DAC releases the call. Three minutes before the inactivity 
timeout takes place, the DAC sends a warning message to the near-end 
equipment if terminal mode is selected.

The DAC allows for the EIA signaling leads to be tested to facilitate 
installation and troubleshooting. This feature can be invoked through the 
service change downloaded parameters, or by setting the appropriate front 
panel switch. Wire test mode only operates when the port is idle. The leads 
are cycled ON and OFF in 0.5 second periods (ON for 0.5 seconds, OFF for 
0.5 seconds) for the number of cycles shown in Table 151 on 

. The 

lead status can be monitored by the front panel LEDs. The test will be run 
indefinitely until the front panel switch is turned off, and the software wire 
test parameters are disabled.

Note: For the most accurate results, be sure no equipment is connected 
to the EIA leads.
