In a multi-site corporate network, IT teams deploy the WIC-1SHDSL-V3-One port G.shdsl WIC with 4-wire support to establish a symmetric 1.5 Mbps link over 12 km between headquarters and remote branches. This solution delivers predictable bandwidth for ERP, VoIP and video conferencing, reduces recurring T1/leased-line expenses by up to 40%, and ensures carrier-grade reliability through line-bonding. Outcome: streamlined operations, lower telecom OPEX, and consistent service level agreements across all locations.
A regional ISP leverages the WIC-1SHDSL-V3-One port G.shdsl WIC with 4-wire support to extend managed broadband services into underserved rural communities. By bonding two copper pairs, the provider delivers up to 2.3 Mbps of symmetric throughput over 18 km, accelerating deployment without fiber construction. Outcome: rapid market expansion, differentiated premium service with SLA-backed speeds, and increased ARPU through value-added voice and VPN bundles.
A utility company implements the WIC-1SHDSL-V3-One port G.shdsl WIC with 4-wire support to connect remote substations and water treatment facilities to its central control center. The symmetric link supports SCADA polling, high-resolution CCTV video, and encrypted traffic over distances up to 15 km without fiber. Outcome: enhanced operational visibility, guaranteed data integrity with AES-256 VPN tunnels, and reduced deployment lead time compared to satellite or microwave solutions.
