3. The application uses these numbers (calling party, dialed, and alerting) to 
search and display (on the data terminal of the message desk) the 
messages left by the originally called party. The called party had used 
electronic mail to create and send these messages to the message desk 
application. These messages are delivered to callers by the message desk 
attendant. If no message was provided, a standard message is given to the 
caller.
4. Messages left by callers are entered as text by the message desk 
attendant. The application sends electronic mail to the called person. Each 
message contains the calling party number. The application then enables 
the message waiting lamp at the telephone.
5. After the customer has read the messages left at the message desk, the 
application disables the message waiting lamp at the telephone.
6. If the application provides voice mailboxes, the customer can listen to voice 
mail messages. This is possible when the application places a call between 
the customer’s telephone and the customer’s voice mailbox. The customer 
can listen, delete, forward, annotate, skip, or save the voice mail 
messages.
7. The customer can also request to dial a call back to the person that left the 
message. The application can place the call while the customer continues 
to read the messages.

Link Configurations
Depending on the size of the system, DEFINITY ECS supports up to eight ASAI 
links. Each link is allowed to connect to a different adjunct, or they can all connect 
to the same adjunct (this depends on the customer’s application). The links can 
be ISDN-BRI or the Ethernet Local Area Network (using TCP/IP). If the link is 
ISDN-BRI, an ISDN-BRI interface is required at each end (one in the DEFINITY 
ECS, one in the adjunct). Ethernet requires a DEFINITY LAN Gateway board in 
DEFINITY ECS and a standard LAN card in the adjunct. The following diagram 
shows how ASAI links can be connected.
Figure 2. Example: Connectivity of ASAI Links
When using the Ethernet LAN, one DEFINITY LAN Gateway board can support 
multiple, ASAI links. For reliability, more than one Gateway boards can be 
provided.

ASAI Features and Event Reports
ASAI provides the following features to an adjunct:
nCall Control
nDomain Control
nNotification
nAdjunct Routing
nRequest Feature
nValue Query
nSet Value
nMaintenance
Each feature is described in the next paragraphs.
Call Control Features
The Call Control features allow the adjunct to place a call, monitor a call, and 
control a call as it moves through the DEFINITY ECS. With call control, an adjunct 
can control any and all parties that are participating in that call. “Control” means 
that the adjunct can tell the DEFINITY ECS what to do with the call (for example, 
hold, transfer, drop). “Control” also implies the DEFINITY ECS sends call event 
reports to the adjunct. The following are features available with Call Control:
nThird Party Make Call
nThird Party Take Control
nThird Party Selective Hold
nThird Party Reconnect
nRedirect Call
nThird Party Merge
nThird Party Selective Drop
nThird Party Selective Listening
nThird Party Relinquish Control
nThird Party Clear Call
nThird Party Send DTMF Signals
nThird Party Call Ended

Third Party Make Call
There are four different ways of making a call using Third Party Make Call: 
nserver classified calls — these are used for predictive dialing. With 
a server classified call, the destination is alerted first. When the 
destination party answers, the call is transferred to an agent. Calls 
that are not answered are disconnected. Usually these calls require 
that a call classifier port be inserted to determine the outcome of the 
call (answered, busy, no answer, etc.).
nuser classified calls — these are normal calls placed on behalf of a 
telephone. They are called “user classified” because the user 
(human being) determines the outcome of the call (by listening to 
the in-band call progress tones).
ndirect agent calls — these are an Automatic Call Distributor (ACD) 
type of calls which are intended for a specific agent. These are used 
when an application selects a specific agent for a call.
nsupervisor assist calls — these are ACD, priority calls that are 
placed by an agent to a supervisor to request assistance.
All of the above Third Party Make Call requests contain information about the 
calling party, called party, and various call options. In addition, the adjunct can 
include special information (User-to-User Information) that is delivered with the 
call when it arrives at the destination. 
When an adjunct places a third party make call, the events that flow as a result of 
that call are provided to the adjunct. In addition, that adjunct can control the call 
and each party in the call.
Third Party Take Control
This is a feature that allows an adjunct to control a call (or all parties in a call) even 
though it did not place the call through a third party make call. The adjunct must 
have known about the call through some other event report. Only one adjunct 
(through one link) can control a call at any given time.
Third Party Selective Hold
This feature allows an adjunct to put a party on the call on hold (just as if the 
HOLD button was used at the telephone). This feature is also used when holding 
a call that is to be conferenced or transferred.
Third Party Reconnect
This feature allows an adjunct to restore the connection for a held party and allow 
the party to be reconnected to others on the call.

Redirect Call
This feature allows an adjunct to take a call that is alerting at a telephone and 
redirect it to another destination. The alternate destination can be locally or 
remotely connected to the DEFINITY ECS. Redirecting is useful when the adjunct 
needs to keep track of un-answered calls so that it knows where to send these 
calls.
Third Party Merge
This feature is used to combine two calls that exist at a telephone in order to 
create a conference or accomplish a transfer. One of the calls must be in the held 
state, while the other is in the active state at the controlling party’s telephone. With 
the “conference” option, this feature combines two calls and places all the parties 
in the conferenced call. With the “transfer” option, this feature combines the two 
calls, but disconnects the controlling party from the call.
Third Party Selective Drop
This feature allows an adjunct to drop (or disconnect) a selected party from a call. 
This can be a telephone or a trunk connected in a call.
Third Party Selective Listening
This feature allows the adjunct to temporarily disconnect a specific party from 
listening to other parties on the call. Using this feature, it is also possible to 
reconnect a specific party back to the original state, so that this party can listen to 
other parties in the call.
Third Party Relinquish Control
Once an adjunct no longer wants to control a call or receive call event reports, this 
feature can be requested to relinquish such control. After requesting this feature, 
no more event reports about the call are sent to the adjunct.
Third Party Clear Call
An adjunct uses this feature to immediately disconnect all parties from a 
controlled call. 
Third Party Send DTMF Signals
This feature is used by an adjunct to provide Dual Tone Multi Frequency (DTMF) 
digits for transmission to all parties in a call.
Third Party Call Ended  
This a feature used by the DEFINITY ECS to inform the adjunct that a call has 
ended (all parties have disconnected).

Domain Control Features
This feature allows the adjunct to place, monitor, and control all calls at a specific 
telephone. Domain control is similar to Call Control, except that the adjunct can 
only manipulate calls at a single telephone (the one that is domain controlled). 
The following are services available with Domain Control:
nThird Party Domain Control Request
— for telephone extension
— for Automatic Call Distributor (ACD) hunt group extension
nThird Party Answer
nThird Party Auto Dial
nThird Party Selective Hold
nThird Party Reconnect
nRedirect Call
nThird Party Merge
nThird Party Selective Drop
nThird Party Relinquish Control
nThird Party Send Dual Tone Multi Frequency (DTMF) Signals
nThird Party Domain Control Ended
Third Party Domain Control Request
The adjunct uses this to start monitoring and controlling a domain. In this case, 
“domain” refers to either a telephone extension or an Automatic Call Distributor 
(ACD) hunt group extension. If used with a telephone extension, this allows the 
adjunct to receive event reports about any of the calls arriving at that telephone 
extension. In addition, the adjunct can control these calls.
If used with an ACD hunt group extension, the monitoring results in events related 
to the agent’s logging into and logging out from the domain controlled ACD hunt 
group.
NOTE:
The following features are available with both Call Control and with Domain 
Control: Third Party Hold, Third Party Reconnect, Redirect Call, Third Party 
Merge, Third Party Selective Drop and Third Party Send DTMF Signals. See 
the descriptions in the previous Call Control section. However, remember 
that domain control features are only applicable to the telephone that is 
domain controlled. In addition, the next list of features are only available with 
Domain Control:

Third Party Answer
When a call is alerting at an extension that is domain controlled, the adjunct can 
use this feature to answer the call. This assumes that the telephone has a 
speakerphone and that it can be taken off hook to answer.
Third Party Auto Dial
This is similar to Third Party Make Call. Unlike a Third Party Make Call, which can 
be dialed on behalf of any party, Third Party Auto Dial can only be done from the 
telephone extension that is domain controlled.
Third Party Relinquish Control
Once the adjunct no longer wants to receive events about any (and all) calls at a 
specific telephone extension, it can use this feature to relinquish its control.
Third Party Domain Control Ended
This feature is used by the DEFINITY ECS to notify the adjunct that the domain 
controlled association has ended. Usually, the association is ended because the 
telephone has been removed or changed from the domain-controlled state.
Event Notification
The Event Notification feature allows the adjunct to request events for certain calls 
from the DEFINITY ECS. Calls entering the domain for which notification was 
requested [Vector Directory Number (VDN), Automatic Call Distributor (ACD)] 
cause event reports to be sent to the adjunct. With notification, the adjunct can 
only observe a call, but can not control it. The following are features available with 
Notification:
nEvent Notification Request
nEvent Notification Cancel
nStop Call Notification
nEvent Notification Ended
Event Notification Request
The adjunct uses Event Notification Request to request event reports for calls 
entering domains of Vector Directory Numbers (VDNs) and Automatic Call 
Distributor (ACD) hunt groups or skills. Calls entering these types of domains 
generate event reports that allow the adjunct to follow the call as it is processed or 
transferred.

32Issue 1  November 1996 
Event Notification Cancel
The adjunct uses Event Notification Cancel when it no longer needs to receive 
event reports for any of the calls entering the notification domain.
Stop Call Notification
The adjunct uses Stop Call Notification when it no longer needs to receive event 
reports for a specific call.
Event Notification Ended
The adjunct uses Event Notification Ended to inform the adjunct that notification 
has ended for a particular domain (usually because of server administration 
changes).
Adjunct Routing
The DEFINITY ECS uses this feature to request and receive routing instructions 
for a call. These instructions, issued by the adjunct, are based on information 
received about the call. A sequence of three messages are included in adjunct 
routing:
nRoute Request
nRoute Select
nRoute End
Route Request
This is a message sent by the DEFINITY ECS to the adjunct when it must obtain a 
route for a call. A Route Request provides any available information about the 
incoming call, such as: Calling Party Number, Called Party Number, 
caller-entered digits, User-to-User Information (UUI), Information Identifier Digits 
(II-Digits), and Flexible Billing information. 
Route Select
The adjunct uses the information received in the Route Request to select the 
destination for the call, and then provides a response to the DEFINITY ECS in the 
Route Select. While providing the new destination for the call, the adjunct can 
insert up to 24 digits which can be stored with the call as dial-ahead digits. UUI 
can also be attached to a call through the Route Select message

33
Route End
This message is used to end the route dialog. It is normally sent by the DEFINITY 
ECS after the Route Select message was processed and the call was routed. 
However, it can also be sent by the adjunct to end routing (for example when a 
valid destination can not be located).
Request Feature
The adjunct uses Request Feature to request or cancel DEFINITY ECS features 
such as agent login, work mode changes, Call Forwarding, Send All Calls, etc. 
These are a subset of features that are available on the DEFINITY ECS and can 
be used when Feature Access Codes are dialed from the telephone. There is only 
one message for Request Feature. The following are the Request Features:
nAgent Login
nAgent Logout
nChange Agent Work Modes
nCall Forwarding
nSend All Calls
Agent Login 
This feature allows the adjunct to log an agent into an Automatic Call Distributor 
(ACD) hunt group or skill and to specify an initial work mode.
Agent Logout   
This feature allows the adjunct to log an agent out from an Automatic Call 
Distributor (ACD) hunt group or skill.
Change Agent Work Modes 
This feature allows the adjunct to request a change in the agent’s work mode for 
an Automatic Call Distributor (ACD) hunt group or skill.
Call Forwarding 
This feature allows the adjunct to request that Call Forwarding be enabled for a 
telephone; all calls that arrive at the telephone will be forwarded to a specified 
destination.

Send All Calls 
This feature allows the adjunct to request that currently alerting calls and 
subsequent calls arriving at the telephone be sent to coverage.
Value Query
This feature allows the adjunct to query for information about DEFINITY ECS 
resources; for example, number of agents logged in, the trunks being used, the 
call classifiers being used, etc. The DEFINITY ECS provides information based 
on the request. The following are features available with Value Query:
nAutomatic Call Distributor (ACD) Agent Login Query
nACD Agent Status Query
nACD Hunt Group Status Query
nCall Classifier Status Query
nCall Information Query
nDate/Time Query 
nExtension Type Query
nIntegrated Directory Database Query
nParty Identification (ID) Query
nStation Feature Query 
— Call Forwarding
— Message Waiting Lamp
— Send All Calls
nStation Status Query
nTrunk Group Status Query
ACD Agent Login Query
This query responds with the physical extension for each agent logged into the 
ACD Hunt Group.
ACD Agent Status Query 
This query responds with the work mode and the state (idle or busy) of an agent.
