About This Document
Intended Audience
This document is written for the application designer responsible for building/programming custom applications and features. This document is also helpful to any individual who needs a functional description of ASAI.
ASAI provides the users with the capability to drive a variety of the ECS features. It is essential, therefore, that the readers of this document should have extensive knowledge of the ECS features and their interactions.
NOTE:
See the ‘‘Related Documents’’ section for a list of manuals that provide the ECS features and ASAI protocol information.
Conventions Used in This Document
An explanation of the conventions used in this document follows.
Chapters 3 through 11 detail the function of each feature or capability of the ASAI. A capability is a request for or an indication of an operation. For example, dropping a party from a call is a capability of ASAI. Related capabilities are grouped into functional sets called capability groups.
Each capability within the group is divided into the following subsections:
■Capability Name
Provides a short overview of the capability and its functions.
■Information Flow
This heading provides information about the flow of data from the adjunct to the ECS or vice versa. For example, the ECS may generate reports for the adjunct (application processor), but the adjunct does not need to respond to these reports. This situation is different when dealing with many of the call control capabilities that require a give and take of data between the ECS and the adjunct.
■<Capability Name> Parameter(s)
This heading documents the type of information (such as the caller_id) that passes between the ECS and the adjunct (usually in the form of a request to the ECS). The actual name is based on the capability being discussed; for example, Call Control Parameters.
■ACK (positive acknowledgement) Parameter(s)
There are many instances when the ECS simply acknowledges the request made by the adjunct and subsequently performs the operation. There are other times when the ECS replies with specific information (such as the identity of the party making the call) to the adjunct within the acknowledgement.
