Figure 9-31
OSI/IP Scenario 3: IP OSS, IP DCN, Other Vendor GNE, OSI DCC, and ONS ENE
shows the same scenario, except the IP-over-CLNS tunnel endpoint is the GNE and not the
DCN router.
1
The IP OSS manages the ONS 15600 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 15600 SDH and other vendor NEs are OSI-only.
3
CTC/CTM communicates with ONS 15600 SDH NEs over a IP-over-CLNS tunnel. The tunnel
is created from the ONS 15600 SDH node to the external router.
4
The ONS 15600 SDH NE exchanges TL1 over the full OSI stack using FTAM for file transfer.
