The Calix GigaSpire BLAST u4g (GS2128G) is a next-generation smart home system that integrates GPON ONT and residential gateway functionalities into a single unit, providing a comprehensive solution for broadband connectivity and an enhanced Wi-Fi experience. This intelligent, high-performance system supports GPON WAN for internet access and leverages the latest 802.11ax (Wi-Fi 6) technology to deliver superior wireless performance.
Function Description
The BLAST u4g serves as a central hub for home networking, offering switching and routing capabilities that support multi-Gigabit throughput for IPTV video and data services. It enables residential subscribers to access broadband data, Internet Protocol (IP) video, and voice (POTS) services. The device is designed to provide optimal whole-home Wi-Fi coverage through simultaneous dual-band 2.4 GHz and 5 GHz operation, coupled with dynamic beamforming. Its integration of a GPON ONT provides carrier-class WAN connectivity, while on the LAN side, it offers Wi-Fi and two Gigabit Ethernet interfaces for connecting customer multi-media devices.
The system is engineered to deliver longer range, higher efficiency, and less interference compared to earlier generations of Wi-Fi technology, making it ideal for delivering HD and UHD (ultra-HD) video and data in a mobile broadband environment. The Calix CommandIQ® app and a phone or laptop can be used by field technicians to install and apply subscriber profiles, or by service providers to configure, activate, and upgrade the BLAST u4g remotely using in-band management or TR-069.

Maintenance Features
The BLAST u4g includes several reset behaviors to facilitate troubleshooting and maintenance:
Basic Reset (Reboot):
- Function: Hardware: Press Reset button once for 1 second. Software: EWI > Utilities > Reboot.
- Expected Behavior: Router or satellite reboots. RG configuration and subscriber's custom settings persist.
- Notes: Pressing the Reset button performs a standard power cycle, all configuration information persists. Device goes off-line for 2-3 minutes while it completes the reboot process.
Configuration Reset:
- Function: Hardware: Press and hold Reset button for 15+ seconds. Software: EWI > Utilities > Restore Defaults.
- Expected Behavior: Router or satellite reboots. RG configuration and subscriber's custom settings persist. Service provider applied management settings persist.
- Notes: Subscriber (Admin) user has access to the EWI to invoke a configuration reset. Device goes off-line for 2-3 minutes while reboot process completes. Press and hold Reset button until LEDs flash (after about 10 seconds). Device goes off-line while it completes the reboot process. Residential Gateway (RG) configuration settings include all subscriber-configurable information such as login credentials for Admin user, SSIDs, LAN IP scope, etc., all of which revert to defaults.
Factory Reset:
- Function: Hardware: no option. Software: (for support user only). EWI > Support > Tools > Smart Activate > Factory Reset.
- Expected Behavior: Router reboots. RG configuration settings reset to factory defaults. Service provider applied management settings reset to factory defaults.
- Notes: Function available only to operators via EWI Support user (not available to subscriber/Admin user). Smart Activate management settings include all information visible on the EWI Support tab, such as login credentials for Support user, TR-69 ACS URL and login credentials, SPID, etc., all of which reset to defaults.
