Interaction of stm with ne:

Example 1.

Gateway NE – provides the TMN network access to all NEs

SDH path

DT channels

Example 2.

Opportunity of multi-level access is given to TMN network user. Basic levels of this access are:

• map of the locality, showing the network topology.

• Network elements

• Different blocks of these network elements

Showing in colour by next way:

Grey colour – basic symbols, common purpose of elements

Red colour – damages: critical damage,

Blue- “damage is not detected” warning, “contingency” state of service

Green – damage is corrected
