unified NMS revolutionizes the vertical management concept by supporting unified management at the Element, Network and Service management layers. Unified Management can be defined as:

  • Management of multiple technology domains from a single platform (wireless backhaul / transport, wireless broadband access, xDSL / VoIP access, etc.).
  • Unified user interface that is modern, simple and convenient to use. Highly-effective service fulfillment & assurance ensure improved user experience and reduced NOC costs.
  • Unified North Bound Interfaces (NBIs) thereby reducing the OSS integration workload.


Optimizing management through simplicity

Following the trend for network convergence, unified management can be applied in various networking scenarios, thus simplifying network roll-out through centralized deployment and auto-discovery capabilities, and network operation via advanced correlation rules and end-to-end performance management.

Before unified management, vertical management silos introduced complexity and repetition that resulted to increased cost and decreased customer satisfaction. See below an example of two vertical management silos in the mobile backhaul domain:

Vertical Network Management silos introduce unwanted complexity and cost


With the introduction of unified management, a single NMS solution manages the whole network with multiple benefits, both technological and financial. See below an example of unified management:

Characteristics and Benefits

Significantly-enhanced service fulfillment that reduces the provisioning time from days to minutes.
Consolidation of multiple NMS teams into one NMS team that improves fault rectification efficiency with OpEx & CapEx savings.
Direct localization of the equipment that is affected by an alarm. Up to 50% improvement in fault rectification efficiency.


Spotting root causes of service unavailability

Service restoration time is critical for operator success. The example shown on the next page illustrates how a unified managed network behaves in case of incidents.

  • Upon service unavailability at customer premises, alarms are issued by all the involved equipment (see the red labels).
  • Unified NMS quickly identifies and rectifies the root cause, which is responsible for services unavailability.

Without a unified management system, the NOC operator would be flooded with alarms presented in different NMS systems, making correlation impossible.

unified NMS revolutionizes the vertical management concept, introducing important benefits in terms of cost savings, decreased complexity and service restoration time.

Have you implemented unified management to manage your networks or are you still using vertical management silos?
