Cisco ROSA Extensions Data Sheet

 
 

 

 

 
 

 
The ROSA™ VoD QAM Manager reports the bandwidth 
utilization of service groups and pinpoints the critical 
service groups. 
 
In a typical network a trade-off is made between initial 
number of QAM channels and the VoD service coverage. 
With the utilization reports of the ROSA VoD QAM 
Manager it is possible to reduce initial capital expense to 
a minimum. The reports allow to react proactively on 
critical service groups by adding additional QAM 
channels ‘last minute’ and by segmenting the HFC 
network. The reports can also be used to evaluate the 
utilization of the network and focus marketing efforts and 
content offering per geographical area.  
 
The System Summary report (see Figure 1) gives an 
overview of the network utilization and reports the critical 
service groups where the threshold limits are reached. 
Each critical service group is analyzed further in the 
Service Group Detail report (see Figure 2), which shows 
the utilization percentage and a summary of the periods 
where threshold limits are exceeded. 
 
The System Summary and Service Group Detail reports are presented as standard reports that are distributed via 
E-mail to a list of users or as customized reports, which are presented as web interfaces to avoid the need to 
install the client software. In the customized reports the threshold limits and report period is definable. 
 

 
Service group utilization monitoring 
•  Report bandwidth utilization percent per service group 

−  Evaluate the utilization per service group 

−  Use reports to analyze the utilization per geographical area 

−  Evaluate and focus marketing efforts and content offering 

•  Allows to plan capital expense and deployment of additional QAM channels 

Reduce the initial capital expense to a minimum, plug-in additional QAMs ‘last minute’ 

•  Helps to predict network segmentation and plan HFC network expansion 

•  Distribute canned reports via E-mail and custom reports via web interface 

•  Definable thresholds and time periods to detect critical service groups 

•  Includes ROSA SNMP Group-wise Equipment Manager for mass configuration of QAM channels 

•  Utilization reports are generated from modulators in the Continuum DVP™ DQA family and D9477 MQAM
