AlphaNet™ EDH-A2
  • Adds DOCSIS Status Monitoring capability to existing power supplies
  • DOCSIS certified, uses existing head-end equipment
  • Compatible with ANSI/SCTE HMS standards
  • Power supply support includes: XM, AM, XM2, ZTT series
  • Embedded Web server for remote diagnostics
  • Local port interface


Alpha’s external DOCSIS transponder provides the ability for cable operators to manage network powering through the existing cable modem infrastructure. DOCSIS certifi cation, SNMP and HMS MIB support, and an embedded web server enable the XP-EDH-A to provide power network 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 SCTE-HMS Management Information Base (MIB) can be monitored with a SNMP compatible Network Management System (NMS) or with a MIB browser. MIB files are required for the MIB browser to collect data from the transponder.
