Accelerating Fiber Rollouts with Pre-terminated Solutions
Celnet led a large-scale baseband unit (BBU) replacement and integration project for a major U.S. carrier’s network upgrade. We swapped out legacy BBUs for advanced Ericsson models across 500+ live sites, ensuring seamless operations in high-traffic environments while meeting strict carrier testing and FCC compliance standards.
Activities were sequenced to limit service interruptions during live upgrades. Integration leveraged ESI for automation, with manual interventions for site-specific configurations. Teams completed NEA/AREA validations, Alarm 66 monitoring, E911 verification, and SRS automated call testing in accordance with carrier specifications. Fiber loss and backhaul challenges were systematically addressed on-site, with full logs and acceptance packages delivered for carrier review.
