RS-366 is a machine interface.  The procedure depends on the
customer’s equipment.

When you set the dial method to RS-366, the Automatic Calling
Equipment (ACU) dials the call using the RS-366 protocol. The
HSL must be idle.  DTR must be ON or the DTR lead must be set
to IGNORE.

For information on the circuits provided on the 25-pin interface
for RS-366 ACU operation, refer to Appendix B, ‘‘RS-366
Interface.’’

When you set the dial method to RS-232, the Data Terminal
Equipment (DTE) connected to the RS-232 interface can use the
ATDmn and ATH commands for call control.

The HSL will automatically adjust its speed (300, 1200, 2400, 4800,
9600, 19200 bps) to match the terminal speed when a command is
entered.

The HSL must be idle and the V.35 DTR lead must be ON to dial a
call. The user enters ATD and the number followed by 

(

RETURN

)

ffffffffff

bbbbbbbbbb  to dial a call.

The HSL does not return result codes to indicate it is
ready, it is connected, or the call was disconnected.

For more information on the circuits provided on the 25-pin
interface for RS-232 call operation, refer to Appendix A, ‘‘RS-232
Interface.’’

When you set the DIAL method to DTR and the HSL is idle, the
HSL dials the number stored in memory location 

M0 

when the

DTR V.35 lead turns ON and hangs up when the DTR turns OFF.

ffffffffffffffffffffffffffffffffffffffffffff

When you set the DIAL method to HOTLINE, and the DTR V.35
lead turns ON, the HSL signals the switch to dial the call
automatically based on a number stored via switch
administration. Turning the DTR lead OFF will disconnect the call.
