TNF1TPS Is Huawei OSN 1800 PDH Board
Huawei OSN 1800 AST2 Board TMB1AST201 Overview
TNF1TPS: Two PD1 boards and one DMS board work together to provide tributary protection switching (TPS).
The TPS board consists of two PD1 boards and one DMS board, and provides the TPS protection function.
Two PD1 boards and one DMS board work together to provide TPS protection.
The TMB1TPS can substitute for the TNF1TPS with the NE software version is V100R019C10SPC300 or later.
After substitution, the TMB1TPS can function only as the TNF1TPS.
If the substitute board does not work with the system control board of the original board, the substitute board cannot be used.
The TMB2TPS can substitute for the TNF1TPS with the NE software version is V100R021C00SPC200 or later.
