Figure 13-33 OSI/IP Scenario 3: IP OSS, IP DCN, Other Vendor GNE, OSI DCC, and ONS ENE
Figure 13-34 shows the same scenario, except the IP-over-CLNS tunnel endpoint is the GNE rather than
the DCN router.
1The IP OSS manages the ONS 15454 and other vendor NEs using TL1 and FTP.
2The other vendor GNE performs mediation for TL1 and FTP, so the DCCs to the ONS 15454
and other vendor NEs are OSI-only.
3CTC/CTM communicates with ONS 15454 NEs over a IP-over-CLNS tunnel. The tunnel is
created from the ONS 15454 node to the external router.
4The ONS 15454 NE exchanges TL1 over the full OSI stack using FTAM for file transfer.
