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.
