IP Tunneling in the DCC channels application
...................................................................................................................................................................................................................................
The figure below shows an example of the IP tunneling in the DCC channels
application. This feature provides a way to manage IP devices through the Data
Communication Network (DCN). An IP EMS (Element Management System) is used
to manage NEs which use IP based management protocols (IP NEs).
The embedded overhead channel (Data Communication Channel) of the Metropolis
®
AMU is used to transport the management data between the IP EMS and the different
NEs.
An IP tunnel can be seen as a set of two static routing entries in nodes on the edge of
the OSI network and the corresponding static entries in the routing table. The LAN
used by IP EMS can also be used by Lucent’s Network Management Systems or
Lucent NMS.
The figure below shows an application with AnyMedia Access equipments (AAS). The
EMS for AAS realizes the management of the different AAS equipments via the
Q-LAN interfaces and using the DCC channels of the different Metropolis
®
AMU.
