2.38.3 SMDI (Simplified Message Desk Interface) AA/VM Signaling
Description
The system may employ SMDI (Simplified Message Desk Interface) protocol to communicate
with an adjunct AA/VM system. When a call is routed to an AA/VM SLT port, the system will send
SMDI messages over the assigned SMDI RS-232 port, informing the AA/VM of the
characteristics of the call.
There are three types of SMDI messages. Within each message is an “Action Code”, which
defines the function or required action of the AA/VM system. Fields within the messages also
define the called/calling station and station status. The various message types and definition of
the fields are shown in the chart below.
