Huawei 020CGK10B7000587-Y3-SST1PSXCSA SST1PSXCSA Telecom System Card / Module

The Huawei SST1PSXCSA is a super dual-plane cross-connect and timing (clock) board used in the Huawei OptiX OSN 3500 SDH transmission platform, part of the wider OptiX OSN family deployed across metro and regional transport networks. The PSXCSA board grooms and schedules services across the subrack’s cross-connect matrix while also providing clock signal input and output for system-wide timing synchronisation, making it one of the core boards responsible for keeping an OSN3500 subrack’s traffic switching and clock references correctly aligned. Through Huawei’s T2000 network management system, engineers can configure the board’s clock synchronisation status, clock source priority table, external clock source output phase-lock source, clock source switching behaviour and clock subnet settings. The OSN3500 platform with this board class supports standard synchronisation features including S1-byte-based clock protection switching, SSM (Synchronisation Status Message) information handling, and IEEE 1588v2 synchronisation support, all of which depend on a correctly functioning cross-connect and timing board. This unit carries material code 020CGK10B7000587-Y3. Tech-Star (UK-based, shipped worldwide) supplies tested Huawei OptiX control, interface and power boards; contact our engineers to confirm compatibility with your OSN3500 configuration.
