This entitlement is designed for environments that need a specific software release tied to DPC/DPC2 hardware support, with licensing scope restricted to ATT use. For network and operations teams, the advantage is precision. Release-specific software licensing helps keep platform versions consistent across deployed systems, which simplifies support planning, change control, and procurement.

This is a software and licensing product, so there are no physical installation attributes to manage. The value is in matching the correct Cisco software release to the correct platform and usage context, reducing ambiguity during ordering, renewal, and lifecycle management. That makes it a strong fit for organizations that need disciplined control over ASR5500 software coverage.
