OSN3500 Technical Specifications

Slot Access Capacity (Packet Mode) introduces the access capacity of each slot. When using the SSN1PSXCS cross board, one service processing board occupies two slots, in which case the adjacent slots are merged two by two, as shown in Figure 1. Figure 1 Slot access capacity (two slots) when using SSN1PSXCS

Huawei OSN3500 device board types:
1. SDH optical interface board (for example, SSN3SL16A-OSN3500 STM-16 optical interface board)
