4.3.1.5 Network Management, Configuration and Maintenance Subsystem
The front NM and Configuration & Maintenance subsystem uses TCP/IP to implement
SNMP NM agent, and performs management by using execution entities of the
managed parties on the bottom layer. The backend NM communicates with the frontend
NM via the network to manage the front systems. In this way, it is possible to isolate the
management network from the transmission network.
