The PowerAgent OSP Concept >>Documents<< PowerAgent OSP is a family of outside-plant status monitoring transponders, each designed for a specific brand and model of Cable TV OSP power supply. PowerAgent transponders are the most capable and flexible series of transponders in the industry because they leverage the ubiquity, low-cost, and proven reliability of off-the-shelf DOCSIS cable modems to enable their network communications capability. This architecture makes PowerAgent transponders DOCSIS future-proof, SNMP and HMS compliant, and uniquely cost-effective. Architecture All PowerAgent transponders are powered from the OSP supply being monitored, and generate DC operating power for the associated DOCSIS modem. The transponder contains a powerful network-enabled processor which implements industry-standard protocols such as TCP/IP, SNMP, HTTP, UDP, DHCP, SMTP, TFTP, and others. The SNMP proxy-agent is fully HMS compliant, ensuring seamless compatibility with other HMS transponders in a multi-vendor installation.
In addition to the network
interface processor, PowerAgent transponders also
contain another processor dedicated to the interface with
the OSP power supply being monitored. This 3-processor
architecture (cable modem processor, network processor,
interface processor) is used to implement a very robust
cross-checking function wherein each processor monitors the
health of the other processors and resets them if a
"lock-up" condition is detected. This self-checking feature
makes PowerAgent transponders extremely robust,
eliminating un-necessary truck-rolls to reset hung-up
transponders. |
