Operational Tasks:


Following basic operational tasks are performed by network management system:

Protection :
Protection switching takes place within milliseconds ( sub 50 ms) & hence Circuit recovery in milliseconds ( failure should not be detected by voice customers)
Restoration:
By doing manual configuration, circuit recovery achieved in seconds or
Provisioning:
Allocation of capacity to preferred routes (according to certain time schedules)
Consolidation:
Moving traffic from unfilled bearers onto fewer bearers to reduce waste trunk capacity
Grooming:
Sorting of different traffic types from mixed payloads into separate destinations for each type of traffic.

OAM Functions and Layers

Level 1 - Regenerator Section: Loss of synchronization, signal quality degradation
Level 2 - Multiplex Section : Loss of frame synchronization, degraded error performance
Level 3 – Path : Assembly and disassembly, cell delineation control.

Data Communication Channel (DCC)


DCC is a in-band channel to facilitate communication between all Network Elements (NE) in a network. This facilitates remote login, alarms reporting, software download, provisioning
