13.6.9.4 OSI/IP Scenario 4: Multiple ONS DCC Areas

OSI/IP Scenario 4
by multiple isolated ONS 15454 areas. A separate IP-over-CLNS tunnel is required to each isolated
ONS 15454 OSPF area. An alternate approach is to create a single IP-over-CLNS tunnel from CTC/CTM
to an ONS 15454 NE, and then to configure a tunnel from that NE to an NE in each isolated OSPF area.
This approach requires additional static routes.

IP and
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 15454 and
other vendor NEs are OSI-only.
CTC/CTM communicates with ONS 15454 NEs over an IP-over-CLNS tunnel between the
ONS 15454 and the GNE.
ONS 15454 NEs exchange TL1 over the full OSI stack. FTAM is used for file transfer.
(Figure 13-35) is similar to OSI/IP Scenario 3 except that the OSI GNE is subtended
