OSI/IP Scenario 4: Multiple ONS DCC Areas
9.6.9.5 OSI/IP Scenario 5: GNE Without an OSI DCC Connection
OSI/IP Scenario 5 (
) 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 15600 SDH NE connection is created to provide
CTC/CTM access.

The IP OSS manages ONS 15600 SDH and other vendor NEs using TL1 and FTP.
2
A separate tunnel is created for each isolated ONS 15600 SDH DCC area.
