The IP OSS manages ONS and other vendor NEs using TL1 and FTP.

The router routes requests to the other vender GNE.

The other vendor GNE performs mediation for TL1 and FTP, so the DCCs to ONS 15600 and other vendor NEs are OSI-only.

CTC/CTM communicates with ONS 15600 NEs over an IP-over-CLNS tunnel between the ONS 15600 and the GNE.

ONS 15600 NEs exchange TL1 over the full OSI stack. FTAM is used for file transfer.

9.7.9.4 OSI/IP Scenario 4: Multiple ONS DCC Areas

OSI/IP Scenario 4 (Figure 9-33) is similar to OSI/IP Scenario 3 except that the OSI GNE is subtended by multiple isolated ONS 15600 areas. A separate IP-over-CLNS tunnel is required to each isolated ONS 15600 OSPF area. An alternate approach is to create a single IP-over-CLNS tunnel from CTC/CTM to an ONS 15600 NE, and then to configure a tunnel from that NE to an NE in each isolated OSPF area. This approach requires additional static routes.
