13.7.9.5 OSI/IP Scenario 5: GNE Without an OSI DCC Connection

OSI/IP Scenario 5 (Figure 13-36) 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 NE connection is created to provide CTC/CTM

access.

1The IP OSS manages ONS 15454 and other vendor NEs using TL1 and FTP.

2A separate tunnel is created for each isolated ONS 15454 DCC area.
