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.
