The IP OSS manages ONS 15600 and other vendor NEs using TL1 and FTP.

The ONS 15600 GNE performs mediation for other vendor NEs.

DCCs between the ONS 15600 GNE and ONS 15600 NEs are provisioned for IP and OSI over PPP.

DCCs between the ONS 15600 GNE and other vendor NEs are provisioned for OSI over LAP-D.

The ONS 15600 and the other vendor NE network include IP over OSPF and OSI over the IS-IS protocol.

The ONS 15600 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 15600 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 15600 NEs, the TID is resolved to both an IP and an NSAP address. The

ONS 15600 GNE follows the current TL1 processing model and forwards the request to the destination NE using the TCP/IP stack and OSPF routing.
