63xE1 (2.048 Mbps) PDH service processing board with 75-ohm electrical interface for the Huawei OptiX OSN 3500/1500 platform.

The Huawei SSN1PQ1A01-75 is a 63xE1 PDH service processing board for the OptiX OSN 3500 SDH transmission platform (the same PQ1-series board is also listed for the OSN 1500). It processes 63 E1 (2.048 Mbps) tributary channels, handling overhead byte processing, alarm and performance-event reporting, and supports tributary protection switching (TPS) for resilient E1 delivery. The 75 suffix denotes the 75-ohm unbalanced electrical interface variant of this board, distinguishing it from 120-ohm balanced versions that use a separate distribution unit; typical maximum power draw for this board family is around 19W at 25 degrees C room temperature. This board is used to aggregate large numbers of legacy E1/PDH circuits, telephony trunks, leased lines, or other 2Mbps services, onto an SDH ring for onward transport. Tech-Star (UK-based, shipped worldwide) holds Huawei OptiX OSN interface boards for network operators maintaining existing SDH infrastructure; contact us to check stock for your subrack configuration.
