13.6.9.4 OSI/IP Scenario 4: Multiple ONS DCC Areas
OSI/IP Scenario 4 (
Figure 13-35
) is similar to OSI/IP Scenario 3 except that the OSI GNE is subtended
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.
1
The IP OSS manages ONS and other vendor NEs using TL1 and FTP.
2
The router routes requests to the other vender GNE.
3
The other vendor GNE performs mediation for TL1 and FTP, so the DCCs to ONS 15454 and
other vendor NEs are OSI-only.
4
CTC/CTM communicates with ONS 15454 NEs over an IP-over-CLNS tunnel between the
ONS 15454 and the GNE.
5
ONS 15454 NEs exchange TL1 over the full OSI stack. FTAM is used for file transfer.
