Between the 5620 SAM Database workstations – required for
sufficient bandwidth for database re-instantiations
NOTE: The higher bandwidth is required to handle
re-instantiation during statistics collection
NOTE: Not required if performance and optical performance
management statistics are not stored in the 5620 SAM Database

Additional bandwidth requirements for LTE performance management
statistics collection
Bandwidth requirements for installations collecting LTE
performance management statistics.
Increased Bandwidth per 200,000 LTE performance
management statistics records
Between a primary and a standby 5620 SAM Server:
If the 5620 SAM Server is collecting the statistics:(5620 SAM
Auxiliary Statistics Collector is NOT installed)
1.0 Mbps
Between a preferred and a reserved 5620 SAM Auxiliary Statistics
Collector if the 5620 SAM Auxiliary Statistics Collector is
collecting the statistics
1.0 Mbps
When a 5620 SAM Auxiliary Statistics Collector is installed to collect statistics using the
5620 SAM Database, the bandwidth requirements between two geographic locations will
need to reflect the state where a 5620 SAM Auxiliary Statistics Collector in geographic
location A may send information to the active 5620 SAM Server in geographic location B
which will - in turn – send information back to the 5620 SAM Database in geographic
location A. For this reason, the bandwidth between geographic location A and B must be
the sum of the bandwidth requirements between the 5620 SAM Auxiliary Statistics
Collector to 5620 SAM Server and 5620 SAM Server to 5620 SAM Database. It is also a
best practice to ensure that the 5620 SAM Auxiliary Statistics Collector, 5620 SAM
Server, and 5620 SAM Database are all collocated in the same geographic site.
5620 SAM Auxiliary Call Trace Collectors
When a 5620 SAM Auxiliary Call Trace Collector is installed, there are a number of
bandwidth requirements listed below. Any bandwidths not listed are not impacted
significantly by call trace data collection.
To handle the redundant pairs appropriately, the bandwidth requirements between two
geographic locations will need to reflect the state where a 5620 SAM Auxiliary Call Trace
Collector in geographic location A may need to provide information to the 5620 SAM-O
Client in geographic location B. The synchronization of call trace and debug trace files
