How to get help

This section explains how to get help for Nortel products and services.

Getting help from the Nortel web site

The best way to get technical support for Nortel products is from the Nortel Technical Support

web site:

www.nortel.com/support

This site provides quick access to software, documentation, bulletins, and tools to address

issues with Nortel products. From this site, you can:

• download software, documentation, and product bulletins

• search the Technical Support Web site and the Nortel Knowledge Base for answers

to technical issues

• sign up for automatic notification of new software and documentation for Nortel

equipment

• open and manage technical support cases

Getting help over the phone from a Nortel Solutions Center

If you do not find the information you require on the Nortel Technical Support web site, and

you have a Nortel support contract, you can also get help over the phone from a Nortel Solu-

tions Center.

In North America, call 1-800-4NORTEL (1-800-466-7835).

Outside North America, go to the following web site to obtain the phone number for your

region:

www.nortel.com/callus

Getting help from a specialist by using an Express Routing Code

To access some Nortel Technical Solutions Centers, you can use an Express Routing Code

(ERC) to quickly route your call to a specialist in your Nortel product or service. To locate the

ERC for your product or service, go to:

www.nortel.com/erc

Getting help through a Nortel distributor or reseller

If you purchased a service contract for your Nortel product from a distributor or authorized

reseller, contact the technical support staff for that distributor or reseller.

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.

NN42020-123 MCS 5100 3.5 Standard 4.0 4.0 January 2006

WSDL is an XML language that contains information about the

interface, semantics and administration of a call to a web service. A

detail description of the WSDL standard is available online at the W3C

(World Wide Web Consortium) web site at the following URL:

www.w3.org/TR/wsdl

Third party client development

The goal of OPI is to allow customer third party applications to interface

with the MCS provisioning system. Once developed, the third party

application will pass an object to a generated stub. The stub will

translate the object into a SOAP message and pass it along to the

skeleton in the Provisioning Module. The skeleton translates the SOAP

message back to an object, and sends it to the Provisioning Module

data store processes. The data store then interfaces with the Oracle

Database. The translations happen in reverse from the Database to the

third party application.

Figure 1 Logical view of OPI interactions

The development of third party provisioning clients involves the

following steps:

• Get the WSDL

• Generate Stub using supported toolkit that supports complex type

• Implement interface to access stubs

• Access stubs from the third party application

Get the WSDL

The WSDL file for MCS is stored on the server hosting the Provisioning

Module. You can view and download the WSDL using a web browser.

Note: By definition, all the OPI commands (methods) are listed in

the WSDL.

From a workstation

1Open a web browser

2To display the WSDL in the web browser, navigate to the

following URL

http://<provclientIP>/prov/services/OPI?WSDL

Where:

<provclientIP> is the IP address used by the Provisioning Client

3Download the WSDL file

Generate stubs

The stub is basically a translator. It takes the “user” object (whatever

type of object) from the interface and converts it to a SOAP message

and sends it to the Provisioning Module. Likewise, a SOAP message

from the Provisioning Module is translated back to the object. HTTP is

used as the transport for OPI. The Provisioning Module listens on port

80 for the SOAP over HTTP messages.

Figure 2 Interactions of the stub

Stubs are generated using a supported toolset. Currently, only the

Apache AXIS 1.0 (Apache extensible Interaction System

http://ws.apache.org/axis) toolset has been tested and approved. AXIS

is Java specific and creates a Java stub. The OPI WSDL may work with

other toolsets, but thorough testing has not yet been completed. Other

toolsets may be supported in subsequent releases once testing has

been completed.

Refer to the chapter Building OPI clients for an example of generating

a Java stub.

Implement interface accessing stubs

An interface must be developed that will access the stubs. The interface

must support authentication on each OPI request.

If the credentials are not present, or fail validation, a SOAP fault will be

sent back indicating the failure and the action will not be performed.

Refer to Error codes and messages on page 29 for a complete list of

error messages.

Access stubs from the third-party application

When the interface accesses/invokes the stubs, the stub will generate

a SOAP message that will be sent to the Provisioning Module on port

80. The stub is basically a translator. It takes the “user” object (whatever

type of object) from the interface and converts it to a SOAP message

and sends it to the Provisioning Module. The skeleton on the server

with the Provisioning Module does the reverse. It takes the SOAP

message and translates it back to a “user” object (whatever type of

object) and sends it to the Provisioning Module’s Data Store that stores

it in the database.

Authentication and authorization

Authentication and authorization of OPI requests are briefly described

in the following sections:

•Authentication

•Authorization

For more information on this topic, please refer to the Provisioning

Client User Guide.

Authentication

Each OPI request is authenticated using HTTP basic authentication.

Each request is required to pass a username and password before

gaining access to the interface. Therefore, there is no login/logout

interface as the request is authenticated on each request. If the

credentials are not present, or fail validation, a SOAP fault will be sent

back indicating the failure and the action will not be performed. The

credentials are verified against any active administrator in the MCS
