The ONS 15454 GNE routes TL1 traffic to the correct NE by resolving the TL1 TID to either an IP or
NSAP address. For TL1 traffic to other vendor NEs (OSI-only nodes), the TID is resolved to an NSAP
address. The ONS 15454 GNE passes the TL1 to the mediation function, which encapsulates it over the
full OSI stack and routes it to the destination using the IS-IS protocol.
For TL1 traffic to ONS 15454 NEs, the TID is resolved to both an IP and an NSAP address. The
ONS 15454 GNE follows the current TL1 processing model and forwards the request to the destination
NE using the TCP/IP stack and OSPF routing.

The IP OSS manages ONS 15454 and other vendor NEs using TL1 and FTP.
The ONS 15454 GNE performs mediation for other vendor NEs.
DCCs between the ONS 15454 GNE and ONS 15454 NEs are provisioned for IP and OSI over
PPP.
DCCs between the ONS 15454 GNE and other vendor NEs are provisioned for OSI over
LAP-D.
The ONS 15454 and the other vendor NE network include IP over OSPF and OSI over the IS-IS
protocol.
