PSR 0833

8 Wire Pairs ­Downconverter

for the Remote Powering System RPS 1600




The new 8 channel remote module is offering a more enhanced feature set and makes the remote powering of active equipment much more efficient. With its embedded enhanced cascade control it is offering a more powerful redundancy across multiple PSR units as it is controlling all PSR units which are combined to a single service. This new cascade service is also signaled via the new cascade-ID to the NMS system and makes the service assignment much more efficient. Further this PSR unit can be easily configured and managed locally by the new software “PSR Control” via an interface cable. Also, software update and adaptation of the RPS 1600 system to different copper line length is offered now.
