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

OSI/IP Scenario 2

ONS 15454 GNE and the other vendor NEs are managed by an IP OSS using TL1 and FTP. The

ONS 15454 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 15454 GNE provides T–TD and

FT–TD mediation to convert TL1/IP to TL1/OSI and FTAM/OSI to FTP/IP.

Cisco ONS 15454 Reference Manual, R7.0.1

All ONS 15454 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 15454 NEs participating in

the OSI network.

IP OSS manages ONS 15454 using TL1 and FTP.

DCCs carry IP over the PPP protocol.

The ONS 15454 network is managed by IP over OSPF.
