Cisco ONS 15600 Reference Manual, R7.2
Chapter 9 Management Network Connectivity
9.7.9 OSI/IP Networking Scenarios
Figure 9-31 OSI/IP Scenario 3: IP OSS, IP DCN, Other Vendor GNE, OSI DCC, and ONS ENE
Figure 9-32 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 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
and other vendor NEs are OSI-only.
3 CTC/CTM communicates with ONS 15600 NEs over a IP-over-CLNS tunnel. The tunnel is
created from the ONS 15600 node to the external router.
4 The ONS 15600 NE exchanges TL1 over the full OSI stack using FTAM for file transfer.
