Engineering detail
Service activation too slow for the 5G portfolio
The route from service application to service opening ran through planning, design, construction, configuration and test as a chain of manual handoffs.
Rising workload, shrinking expertise
Parallel 3G, 4G and 5G operation multiplied managed entities while the engineers who held the build knowledge were leaving.
A deeply heterogeneous estate
Multivendor IP routers, operator specification L2 switching, WDM and ROADM optics. No single equipment vendor's tooling could span it.
Carrier grade reliability, no development cycles
Automation had to raise throughput without weakening reliability, and absorb new device types and business rules through configuration.

Vendor abstraction

- Reconciliation against the live network. Where configuration changed outside the system, the device is read back and compared with the design record, and the divergence is surfaced rather than overwritten.
- Vendor abstraction as a design goal. New equipment is onboarded by extending the device library, not by rewriting automation logic.
- Change absorbed without a development cycle. New commands, branches, tasks and device types are introduced through the GUI. This was the requirement pressed hardest, because it decides cost of ownership.
