AlphaNet™ EDH3 (CMD-P)
AlphaNet™ EDH3 (CMD-P)
  • Adds DOCSIS Status Monitoring capability to existing power supplies
  • DOCSIS certified, uses existing headend equipment
  • Compatible with ANSI/SCTE HMS standards
  • Power supply support includes: XM, AM, XM2, ZTT series
  • Embedded Web server for remote diagnostics
  • E-MTA performs advanced VoIP testing
  • Replaces AlphaNet model EDH2 External DOCSIS Transponder


Alpha’s external DOCSIS transponder provides the ability for cable operators to manage network powering through the existing cable modem infrastructure. DOCSIS certification, SNMP and HMS MIB support, and an embedded web server enable the EDH3 (CMD-P) to provide network power data quickly and easily when and where it is needed. The transponder is fully interoperable with multiple power supply models and can be accessed using any SNMP Manager.

The EDH3 (CMD-P) can also be optionally enabled as an E-MTA to perform an advanced suite of IP and VoIP tests, thus turning it into a true cross-domain test point by combining measurements available from the HFC, DOCSIS, IP and VoIP domains.
