 NT7D16 Data Access card

When used for inbound or outbound gateway access, the DAC can be 
configured as R232 in LD 11. When used for both inbound and outbound 
gateway access, the DAC must be configured as R232. When the DAC is 
programmed as station hunting, outbound gateway access should be in the 
opposite direction to the hunting for inbound gateway access. See Figure 89 
on 

 for more details.

Note: If CDR is required, use separate outbound and inbound gateway 
access.

This mode should be selected when the DAC is connected to a gateway for 
inbound Hotline operation. The operation of this mode is similar to mode 5 
except for the following:

•

The DTR lead is ON in the idle state.

•

The DTR lead will be dropped OFF for 0.2 second when an established 
call is disconnected.

The baud rate of inbound Hotline calls is determined by programmable 
database. The system should be programmed to allow inbound calls only on 
the DAC unit.

The DAC must be configured as R232 (the Autodial feature is used for this 
mode). The DAC must not be configured as an ADM trunk.

Select modes 8, 9, 10, and 11 when the DAC is connected to different types 
of hosts (DTE). In these modes, the DAC operates as a DCE and drives DSR, 
DCD, and RI control leads (see Figure 90 on 

). CTS, DSR, and DCD 

are driven OFF in the idle state.

The DAC will not send any menu or prompt to the host, nor will it echo any 
command sent from the host. The CTS, DSR, and DCD will be driven ON 
until the call is released. An incoming call to the DAC causes the RI lead to
