CTI OS Client Interface Library Architecture

This chapter describes the architecture of the CTI OS Client Interface Library (CIL). The CIL is the
programmer’s interface into the CTI OS system.

Object Server Architecture

CTI OS is a Server-based integration solution, which enables all objects to exist on the CTI OS server.
The client-side objects, through which the developer can interact with the CTI OS CIL, can be
conceptually thought of as a thin proxy for server-side objects.

All objects are identified by a UniqueObjectID. The UniqueObjectID is the key which is used to map a
server-side object and the client-side proxy (or proxies) for it. Requests made on a client-side object will
be sent to the CTI OS Server, and the corresponding server-side object will service the request
(

Client Interface Library Architecture

The Client Interface Library has a three-tiered architecture (

Figure 2-2

), which implements the

functionality provided to developers. The CIL architecture is composed of the Connection layer, the
Service Layer and Object Interface Layer. The CIL architecture also includes the custom application,
which is developed by the customer to make use of the services provided by the Client interface Library.
