13.7.9.5 OSI/IP Scenario 5: GNE Without an OSI DCC Connection
OSI/IP Scenario 5 (Figure 13-34) is similar to OSI/IP Scenario 3 except that the OSI GNE only has an
IP connection to the DCN. It does not have an OSI DCN connection to carry CTC/CTM IP traffic through
an IP-over-OSI tunnel. A separate DCN to ONS 15454 SDH NE connection is created to provide
CTC/CTM access.
1 The IP OSS manages ONS 15454 SDH and other vendor NEs using TL1 and FTP.
2 A separate tunnel is created for each isolated ONS 15454 SDH DCC area.
