9.6.9.4 OSI/IP Scenario 4: Multiple ONS DCC Areas

OSI/IP Scenario 4
by multiple isolated ONS 15600 SDH areas. A separate IP-over-CLNS tunnel is required to each isolated
ONS 15600 SDH OSPF area. An alternate approach is to create a single IP-over-CLNS tunnel from
CTC/CTM to an ONS 15600 SDH 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 15600 SDH
and other vendor NEs are OSI-only.
CTC/CTM communicates with ONS 15600 SDH NEs over an IP-over-CLNS tunnel between
the ONS 15600 SDH and the GNE.
ONS 15600 SDH NEs exchange TL1 over the full OSI stack. FTAM is used for file transfer.
(Figure 9-33) is similar to OSI/IP Scenario 3 except that the OSI GNE is subtended
