The IP OSS manages the ONS 15600 and other vendor NEs using TL1 and FTP.
The other vendor GNE performs mediation for TL1 and FTP, so the DCCs to the ONS 15600
and other vendor NEs are OSI-only.
CTC/CTM communicates with ONS 15600 NEs over a IP-over-CLNS tunnel. The tunnel is
created from the ONS 15600 node to the external router.
The ONS 15600 NE exchanges TL1 over the full OSI stack using FTAM for file transfer.
