Ericsson MINI-LINK TN R4 ETSI, Technical Description

Page: 54 / 149

Technical Description
Note that the TDM bus can carry close to 400 uni-directional E1s in AMM 20p B
and AMM 6p C/D, half of this in AMM 2p B, but some of the capacity is allocated
for DCN and control information. To facilitate future software functional
upgrades it is not recommended to route traffic on more than 366 uni-directional
E1s over the AMM 6p C/D and AMM 20p B TDM bus, half of this in AMM 2p B.
The traffic routing function is controlled from MINI-LINK Craft, locally or
remotely.
Traffic configuration can also be done using the SNMP interface.
3.9.1 ServiceOn Network Manager
The ServiceOn Network Manager (SoNM ) provides a way to provision
end-to-end E1 connections in a network. All operations related to the E1
provisioning are done from a graphical representation of the network nodes
and the E1 connections.
Color codes are used to visualize alarm status. Detailed alarm info and status
are shown in near real time. In addition the "Root Cause" feature at the Network
level suppresses lower order alarms that occur as a consequence of higher
level fault. This reduces the impact of major disruptions on the operators by
only showing the major network faults. A number of different reports can be
extracted on demand to view performance data and statistics related to an E1
end-to end connection.
