13.7.9 OSI/IP Networking Scenarios
Figure 13-31 OSI/IP Scenario 3: IP OSS, IP DCN, Other Vendor GNE, OSI DCC, and ONS ENE
Figure 13-32 shows the same scenario, except the IP-over-CLNS tunnel endpoint is the GNE rather than
the DCN router.
1 The IP OSS manages the ONS 15454 SDH and other vendor NEs using TL1 and FTP.
2 The other vendor GNE performs mediation for TL1 and FTP, so the DCCs to the
ONS 15454 SDH and other vendor NEs are OSI-only.
3 CTC/CTM communicates with ONS 15454 SDH NEs over a IP-over-CLNS tunnel. The tunnel
is created from the ONS 15454 SDH node to the external router.
4 The ONS 15454 SDH NE exchanges TL1 over the full OSI stack using FTAM for file transfer.
