Open Provisioning Interface introduction

The Open Provisioning Interface (OPI) is used to remotely provision the Multimedia Communication Server (MCS) system. OPI is based on the Simple Object Access Protocol (SOAP) 1.1 and the emerging web services standard. SOAP is a cross-platform, cross-language text based protocol utilizing the benefits of XML (extensible Markup Language). SOAP is commonly used as a tool in distributed applications named web services. While SOAP in itself is not transport dependent, OPI relies on HTTP (Hyper Text Transfer Protocol) as its transport.

OPI gives the service provider the means to integrate MCS provisioning with their own applications by allowing:

•Machine-to-machine interface for provisioning tasks

•Pass-through provisioning from existing provisioning systems

•Support for the Bulk Provisioning Tool

For information on the BPT, refer to the Bulk Provisioning Tool Reference Guide.

Web Services Description Language (WSDL) 1.1

OPI supports the industry standard Web Services Description Language (WSDL) 1.1. WSDL allows the service provider to provision their MCS system with existing and custom applications. By supporting the WSDL standard, service providers can rapidly develop client side code with standard toolsets.
