Chapter 13 Management Network Connectivity
13.7.9 OSI/IP Networking Scenarios
TL1 management is not required.
FTP file transfer is not required.
TL1 and FTAM to FTP mediation is not required.
Management traffic between CTC/CTM and ONS 15454 SDH NEs is carried over an IP-over-CLNS
tunnel. A static route is configured on the ONS 15454 SDH that terminates the tunnel (ONS 15454 SDH
NE 1) so that downstream ONS 15454 SDH NEs (ONS 15454 SDH NE 2 and 3) know how to reach
CTC/CTM.
13.7.9.8 OSI/IP Scenario 8: OSI OSS, OSI DCN, ONS GNE, OSI DCC, and Other Vendor NEs
OSI/IP Scenario 8 (Figure 13-37) is another example of a European network. Similar to OSI/IP Scenario
7, the ONS 15454 SDH NEs are solely managed by CTC/CTM. The CTC/CTM IP traffic is carried over
an IP-over-OSI tunnel between an external router and the ONS 15454 SDH GNE. The GNE extracts the
IP from the tunnel and forwards it to the destination ONS 15454 SDH. Management traffic between the
OSS and other vendor NEs is routed by the ONS 15454 SDH GNE and NEs. Routing is possible because
all ONS 15454 SDH NEs run dual stacks (OSI and IP).
