Programing DAC for mode 9 in service change LD 11
The DAC must be configured as R232 or R422 (the Autodial feature is used
for this mode). The DAC must not be configured as an ADM trunk.
Mode 10
This mode should be selected when the DAC is connected to a host for
inbound host accessing. The host in this mode is not required to monitor RI
or drive DTR. This mode is similar to mode 8, except for the following:
• The status of DTR lead is assumed to be always ON, even when the
actual condition of that lead is OFF (forced-DTR). The DAC always
answers an incoming call regardless of the status of DTR.
• The host cannot release an established data call by driving DTR OFF. As
a result, the host cannot initiate call release except with a long break or
three short breaks.
In this mode, the DAC does not send any menus or prompts to the host.
However, the host can still originate an outgoing call by blind-dialing
(sending commands to the DAC without receiving echoes).
Programing DAC for mode 10 in service change LD 11
When used for inbound or outbound host access, the DAC can be configured
as R232 in LD 11. When used for both inbound and outbound host access, the
DAC must be configured as R232. When the DAC is programmed as station
hunting, outbound host access should be in the opposite direction to the
hunting for inbound host access.
Note: If CDR is required, use separate outbound and inbound gateway
access.
Mode 11
This mode provides a “virtual leased line” and the meaning of the Forced
DTR switch is re-defined. The operation is similar to having a leased line
feature, where the connection between two extensions is always established.
The DAC does not send any menus or prompts to the host. The baud rate of
the Hotline call is determined by switches 6, 7, and 8.
