1678 MCC benefits in the networks

>

Office modernization

>

ADM and BB-DXC in one only box

60% to 80% price reduction with respect to old gen DCS
No longer multi-rack configurations: 4K capacity in one compact
shelf

Networks simplification

Only one NE and one Network Layer for Network Management

Restoration CAPEX reduction due to port savings
Automatic bandwidth allocation & distributed protection save
Network operators manual intervention
Integrated data functionalities (GbE ptp and L2 switch)

End-to-end provisioning Challenges

Delays in provisioning have been attributed to the manual process involved

in formulating routes based on specific constraints, determining if there is enough
capacity to support the route, and manually provisioning each segment of the route.
Historically these functions have been manually supported by network operators and
planners and have been supplemented by network management systems. (RHK)
