Huawei 020TLC10B7000118-Y3-SSN6GSCC SSN6GSCC Telecom System Card / Module

The Huawei SSN6GSCC is a System Control and Communication board (GSCC) used in the Huawei OptiX OSN 3500 and OSN 7500 SDH transmission platforms, part of the OptiX OSN family widely deployed across metro and regional transport networks. The GSCC provides the central control function for the subrack: it handles system control, orderwire (engineering voice channel) processing, inter-board communication, and monitors the system’s power supply status, making it one of the more critical boards in an OSN3500/OSN7500 configuration. GSCC boards are normally deployed in 1+1 redundancy, so that a working spare automatically takes over system control if the active unit fails, minimising the risk of a full subrack outage from a single control-board fault. The GSCC family covers several functional versions (N1, N3, N4, N6 among them) tailored to different OSN hardware generations, so engineers should confirm the exact GSCC variant required by their existing subrack before fitting a replacement. This specific unit carries material code 020TLC10B7000118-Y3.
