The IP OSS manages ONS 15454 and other vendor NEs using TL1 and FTP.
The other vendor GNE performs mediation on TL1 and FTP, so DCCs are OSI-only.
CTC/CTM communicates with ONS 15454 NEs over a separate IP DCN connection.
ONS 15454 NE exchanges TL1 over the full OSI stack. FTAM is used for file transfers.
(Figure 13-37) shows how the ONS 15454 supports OSI DCNs. The OSI DCN has no
