13.6.5.4 Manual TID to NSAP Provisioning

TIDs can be manually linked to NSAPs and added to the TDC. Static TDC entries are similar to static
routes. For a specific TID, you force a specific NSAP. Resolution requests for that TID always return
that NSAP. No TARP network propagation or instantaneous replies are involved. Static entries allow you
to forward TL1 commands to NEs that do not support TARP. However, static TDC entries are not
dynamically updated, so outdated entries are not removed after the TID or the NSAP changes on the
target node.
13.6.6 TCP/IP and OSI Mediation
Two mediation processes facilitate TL1 networking and file transfers between NEs and ONS client
computers running TCP/IP and OSI protocol suites:
