EMS Integration Toolkit

1. Overview

The EMS Integration Toolkit is a collection of browser-based utilities designed for Telecom and Network OSS engineers. These tools help with common tasks encountered when integrating Element Management Systems (EMS) with Operations Support Systems (OSS).

2. Getting Started

Accessing the Toolkit

1. Open your web browser and navigate to https://emstools.web.app
2. Sign in with your Google account
3. Select the tool you need from the navigation tabs

System Requirements

• Modern web browser (Chrome, Firefox, Edge, Safari)
• JavaScript enabled
• Internet connection for initial load only

Navigation

The toolkit uses a tab-based navigation system. Click on any tab at the top of the screen to switch between tools. Your work in each tool is preserved while switching tabs.

3. TL1 Parser/Builder

What is TL1?

Transaction Language 1 (TL1) is a widely-used management protocol in telecommunications. It provides a standardized command structure for managing network elements.

TL1 Command Structure

COMMAND-CODE:TID:AID:CTAG::PARAMETER1=VALUE1,PARAMETER2=VALUE2;

Using the Parser

1. Select the "TL1 Parser/Builder" tab
2. Choose "Parse TL1" mode
3. Paste your TL1 command into the input field
4. Click "Parse Command"
5. View the parsed components in the results panel

Example Input

RTRV-ALM-ALL:NETWORKELEM1:SLOT-1-1:123::TYPE=CRITICAL,SRVEFF=SA;

Parsed Output

{
  "command": "RTRV-ALM-ALL",
  "tid": "NETWORKELEM1",
  "aid": "SLOT-1-1",
  "ctag": "123",
  "parameters": {
    "TYPE": "CRITICAL",
    "SRVEFF": "SA"
  }
}

Using the Builder

1. Select "Build TL1" mode
2. Fill in the command components (Command, TID, AID, CTAG)
3. Add parameters using the "Add Parameter" button
4. Click "Build Command"
5. Copy the generated TL1 command

4. Alarm Mapper

Purpose

The Alarm Mapper helps you create and manage mappings between EMS-specific alarm codes and standardized OSS alarm descriptions. This is essential for alarm correlation and unified monitoring.

Creating a Mapping

1. Select the "Alarm Mapper" tab
2. Enter the EMS alarm code (e.g., ALM_001)
3. Enter the OSS description (e.g., Link Down)
4. Select the severity level:
   • Critical - Service affecting, immediate action required
   • Major - Significant impact, urgent attention needed
   • Minor - Limited impact, scheduled attention
   • Warning - Potential issue, monitoring required
   • Info - Informational, no action needed
5. Click "Add Mapping"

Mapping Table

All mappings are displayed in a table format showing:

• EMS Code - The original alarm identifier
• OSS Description - Standardized alarm description
• Severity - Color-coded severity level
• Actions - Edit or delete mapping

Export/Import

Exporting Mappings

1. Click the "Export" button
2. Choose format: JSON or CSV
3. The file will download automatically

Importing Mappings

1. Click the "Import" button
2. Select a JSON or CSV file
3. Mappings will be added to your existing list

CSV Format

emsCode,ossDescription,severity
ALM_001,Link Down,critical

ALM_003,Config Changed,info

JSON Format

[
  {
    "emsCode": "ALM_001",
    "ossDescription": "Link Down",
    "severity": "critical"
  },
  {
    "emsCode": "ALM_002",
    "ossDescription": "High CPU Usage",
    "severity": "major"

3. Paste your data in the input area
4. Select the target format
5. Click "Transform"
6. Copy or download the result

Example: JSON to XML

Input (JSON):

{
  "alarm": {
    "id": "12345",
    "severity": "critical",
    "source": "router-01"
  }
}

Output (XML):

<?xml version="1.0" encoding="UTF-8"?>
<alarm>
  <id>12345</id>
  <severity>critical</severity>
  <source>router-01</source>
</alarm>

Working with CSV

When converting to/from CSV:

8. E2E Integration Generator

Overview

The E2E Integration Solution Generator is a comprehensive wizard that guides you through designing complete integration solutions. It automatically generates architecture diagrams, code artifacts, and deployment configurations based on your requirements.

Four-Phase Approach

Phase 1: Requirements

Capture all integration requirements through six sub-sections:

• Project Name - Unique identifier for your integration (required)
• Description - Brief description of the integration purpose
• Integration Type - ETL/Batch, Real-time Streaming, API Integration, or Hybrid
• Pattern - Point-to-Point, Hub-and-Spoke, Publish-Subscribe, or Event-Driven
• Tech Stack - Java/Spring Boot, Python, or Node.js

1.2 Source System

• System Type - Database, REST API, File System, Message Queue, FTP/SFTP
• System Name - Identifier for the source system (required)
• Data Format - JSON, XML, CSV, Avro, or Parquet
• Connection Details - Connection string or endpoint
• Schema Definition - Sample data or schema structure (required)

1.3 Destination System

Same configuration options as Source System for the target endpoint.

1.4 Data Mapping

• Source Field - Field name from source system
• Destination Field - Corresponding field in destination
• Transformation - Direct Copy, Concatenate, Split, Lookup, Format/Convert, or Custom Logic

At least one field mapping is required.

1.5 Business Rules (Optional)

• Rule Name - Descriptive name for the rule
• Action - Filter/Exclude, Transform, Route/Split, Aggregate, Enrich, or Validate

• Logging Level - Debug, Info, Warning, or Error Only
• Scheduling - Real-time, Hourly Batch, Daily Batch, or Custom Cron
• Performance Target - Records per second
• Security - Data Encryption, Authentication, Data Masking, Audit Logging

Phase 2: Design

After clicking "Generate Design", the system creates:
