An analog station, analog OPS, or T1 OPS is configured as an SOD in AMO SCSU. When an SOD answers an ACD call via a Route-to-Agent, Route-to-Group, or Route-to-Extension ART step, the internal and/or external DNIS number associated with the call is outpulsed to the SOD. The exact DNIS number(s) to outpulse is determined by system flag TYPEDNIS in AMO ZAND. Outpulsing of DNIS digits after the SOD answers begins after the time period (OHDELAY1) defined in AMO DTIM2.

SODs can be configured as autologon Agents. Such Agents enter indefinite work mode automatically when they go offhook and then onhook without dialing any digits. They must go offhook and enter the available mode access code to be routed to as an Agent again. This is required to prevent the ACD from routing calls to the SOD when it is unavailable e.g. when back-up operations are in place.
