9.7.9.6 OSI/IP Scenario 6: IP OSS, OSI DCN, ONS GNE, OSI DCC, and Other Vendor ENE
OSI/IP Scenario 6 (Figure 9-35) shows how the ONS 15600 supports OSI DCNs. The OSI DCN has no
impact on the ONS 15600 because all IP traffic (CTC/CTM, FTP, and TL1) is tunneled through the OSI
DCN.
1 The IP OSS manages ONS 15600 and other vendor NEs using TL1 and FTP.
2 The other vendor GNE performs mediation on TL1 and FTP, so DCCs are OSI-only.
3 CTC/CTM communicates with ONS 15600 NEs over a separate IP DCN connection.
4 ONS 15600 NE exchanges TL1 over the full OSI stack. FTAM is used for file transfers.
