AlphaNet EDH-A
  • Power supply support includes: XM2, XM, AM, ZTT+ and CPR
  • Compatible with ANSI/SCTE HMS standards
  • Embedded Web server for remote diagnostics


Alpha’s External DOCSIS Transponder provides the ability for cable operators to manage any network UPS through the existing cable modem infrastructure. Alpha’s EDH-A 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.
