1. Identify the platform
Confirm the exact product, model, interfaces and installed DGW release.
Resources
Security & Trust Center
Review security advisories, supported versions, lifecycle information, cryptographic practices and vulnerability reporting.
DOCUMENT CONTROL
Use security & trust center in a controlled workflow.
The right document is the one that matches the exact platform, release and task in front of the engineer.

02
2. Select Security & Trust Center
Choose the resource that matches the engineering task and release—not just a familiar filename.
03
3. Back up & plan
Capture current configuration, acceptance tests and rollback conditions.
04
4. Apply in a window
Make the controlled change and observe signaling, media, interfaces and alarms.
05
5. Record acceptance
Retain results, new configuration state and support ownership.

READING THE DIAGRAM
Documentation is part of change control
- Data sheet
- Supports initial model and interface selection; it is not a configuration procedure.
- Configuration guide
- Explains how a supported feature or topology is set up for an applicable DGW release.
- Release notes
- Explain changes, fixes and considerations between specific software versions.
- Technical bulletin
- Addresses a defined operational, security or product issue and its affected scope.
Controlled documentation path — verify release support and entitlement before changing a production platform.
RESOURCE SELECTOR
Choose the document by task—not by filename.
Each document answers a different engineering question and may apply only to specific hardware or DGW releases.
Production changes should include a configuration backup, test plan, rollback decision and valid support path.| Resource | Use it for | Confirm first | Output |
|---|---|---|---|
| Data sheet | Initial product fit | Exact model and option | Capacity / interface shortlist |
| Installation guide | Rack, power and cabling | Hardware revision | Installed platform |
| Configuration guide | Feature and call-path setup | DGW release and topology | Controlled configuration |
| Release notes | Change and upgrade review | Current and target release | Upgrade decision |
| Technical bulletin | Specific advisory or action | Affected products and versions | Documented remediation |
FREQUENTLY ASKED
What to know before the next step.
Match the material to the exact product, model, DGW release and engineering task before applying it to production.
Record the current release and configuration, the reason for change, the test plan, rollback point and support entitlement.
Contact M5 when release applicability, licensing, interoperability, upgrade sequencing or production risk cannot be resolved from the published material.
