9.6.9.2 OSI/IP Scenario 2: IP OSS, IP DCN, ONS GNE, OSI DCC, and Other Vendor ENE

OSI/IP Scenario 2
the ONS 15600 SDH GNE and the other vendor NEs are managed by an IP OSS using TL1 and FTP. The
ONS 15600 SDH is also managed by CTC and Cisco Transport Manager (CTM). Because the other
vendor NE only supports TL1 and FTAM over the full OSI stack, the ONS 15600 SDH GNE provides
T–TD and FT–TD mediation to convert TL1/IP to TL1/OSI and FTAM/OSI to FTP/IP.
Cisco ONS 15600 SDH Reference Manual, Release 9.0
9-44
All ONS 15600 SDH NEs participating in an OSI network run OSI over PPP between themselves.
This is needed so that other vendor GNEs can route TL1 commands to all ONS 15600 SDH NEs
participating in the OSI network.
