Today we introduce a Huawei OSN3500 transmission device N1, N2 main differences between the single boards

N1 series single boards: SSN1SEP1; SSN1SEP; SSN1SLQ1; SSN1SL1; SSN1SLQ4; SSN1SLD4; SSN1SL4;SSN1SL16;

N2 series veneer: SSN2SLQ1; SSN2SL1; SSN2SLQ4; SSN2SLD4; SSN2SL4; SSN2SL16; SSN2SL64;

The basic rule of N1/N2 naming is that N1 single board uses the company's own chip, such as SD543 currently used; N2 single board uses TSOT1610G.

N2 single board supports TCM function, N1 does not.

N2 single board supports Au3 level service configuration and alarm, AU3 level high order channel overhead maintenance, etc.; N1 single board does not support.

In terms of loopback, N2 single board supports internal and external loopback of optical ports; N1 single board supports internal and external loopback of optical ports and internal loopback of VC4 channels.

In terms of reverse loopback insertion into AUAIS, N1 and N2 single boards have the following points in common: external loopback is possible; internal loopback is not possible.
