AlphaNet EDH2
  • Supports multiple power supply models, multiple battery strings and a generator
  • Compatible with ANSI/SCTE HMS standards
  • Optional VoIP testing features


Alpha’s External DOCSIS Transponder provides the ability for cable operators to manage any network UPS through the existing cable modem infrastructure. Alpha’s EDH2 transponder supports monitoring multiple power supply models including XM2, XM, AM, ZTT/Plus and CPR. The power supply, multiple batteries and a generator can be monitored using a single transponder. Power supply status is transmitted to a management system over the network’s DOCSIS cable modem channels through the existing CMTS. Bandwidth use is minimized by using standard SNMP (Simple Network Management Protocol) communications. Status monitoring information is compatible with ANSI/SCTE HMS standards. Optional VoIP testing functionality allows power supply transponder to become a powerful network diagnostic tool.
