Telecommunications Protocols¶

TelcoAPI provides comprehensive support for both legacy and modern telecommunications protocols, enabling seamless integration with various network elements and services.

Protocol Integration Overview¶

Our API supports multiple integration patterns to accommodate different network architectures:

• Direct Integration: Connect directly to network elements
• Gateway Mode: Use our protocol gateway for simplified integration
• Hybrid Deployment: Mix direct and gateway modes based on needs

Protocol Selection Guide¶

Choose the appropriate protocol based on your needs:

Implementation Examples¶

Basic Protocol Usage¶

from telco_api import TelcoClient

# Initialize client with your credentials
client = TelcoClient(api_key="your_api_key")

# SS7 MAP Operation
response = client.ss7.send_map_message(
    destination="123456789",
    operation="sendAuthenticationInfo",
    parameters={
        "imsi": "123450123456789"
    }
)

# Diameter Authentication
auth_request = client.diameter.create_request(
    application_id=16777251,  # S6a
    command_code=318,         # AIR
    realm="example.com"
)

Best Practices and Security¶

Security Considerations¶

1. Authentication and Authorization
2. Use strong API keys
3. Implement role-based access control

4. Regular key rotation

5. Network Security

6. Enable SCTP/TLS for Diameter
7. Use IPSec for SS7 connections

8. Implement SIP TLS and SRTP

9. Monitoring and Logging

10. Set up real-time alerts
11. Monitor protocol-specific KPIs
12. Maintain audit logs

Performance Optimization¶

• Use connection pooling
• Implement retry mechanisms
• Configure appropriate timeouts
• Enable protocol-specific optimizations

Troubleshooting Guide¶

Common issues and solutions:

Connection Issues¶

1. SS7 Connectivity
2. Check point code accessibility
3. Verify linkset status

4. Confirm network routing

5. Diameter Connection

6. Verify realm configuration
7. Check peer connectivity

8. Validate TLS certificates

9. SIP Problems
