This mode should be selected when the DAC is connected to a host and 
continuous Hotline operation is required. In this mode, the DAC repeatedly 
tries to Hotline to the Autodial DN as long as DTR is ON. When the DAC 
tries to Hotline to a busy Data Module, it activates Ring Again and the 
connection is established as soon as the called unit is free. After establishing 
the data call, if the called unit releases the call for any reason, the DAC will 
automatically try to Hotline again to reestablish the call.
If the data unit being called does not answer the Hotline call, the DAC tries 
to place another Hotline call once every 40 seconds until the called unit 
answers. This mode is recommended only when a permanent connection 
between a host and another data unit is required.
Programing DAC for mode 11 in service change LD 11
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.
Selecting the proper mode for Terminal connectivity
Select modes 12, 13, 14,and 15 when the DAC is connected to different types 
of terminals. In these modes, the DAC operates as a DCE, drives DSR, DCD, 
and RI control leads, and monitors DTR lead in modes 12, 13, and 15 (see 
Figure 91 on 
). DTR is ignored in mode 14. All the menus and 
prompts are sent to the terminals and all the commands from the terminals are 
echoed. CTS, DSR, and DCD are driven OFF during the idle state (data call 
is not established).
When the call is released, DSR and DCD are turned OFF for 200 ms. The RI 
lead is controlled only in modes 12, 13, and 15, and is driven OFF in the idle 
and connect states. An incoming call to the DAC causes the RI lead to go ON 
for 2 seconds and then OFF for 4 seconds until the call is answered by the 
terminal. When the terminal turns DTR ON, the DAC answers the call.
Mode 12
This mode should be selected when the DAC is connected to a terminal 
(DTE) for inbound and outbound data calls. This mode is similar to the 
operation of the ASIM when set to not-forced-DTR and not-Hotline. In this 
mode, call origination and auto-answer will not be executed by the DAC,
