- Embedded network management for Alpha broadband power supplies
- Battery and power supply advanced diagnostics reduces truck rolls and overall operating expense of maintaining a network
- Three models available: DSM3 (standard), DSM3x (advanced) and DPM (XM2-300HP)
The AlphaNet family of networking products, including the 3rd generation DOCSIS® Status Monitoring broadband power communication card, enables Alpha’s XM2-HP, XM2, XM2-300HP and GMX CableUPS® to connect directly to an HFC network through an embedded DOCSIS cable modem.
Through a Simple Network Management Protocol (SNMP) interface, standard MIBs are used for quick, efficient network status and diagnostics. A WEB interface enables any authorized personnel direct access to powerful, advanced diagnostics using a common web browser. No proprietary software is required. A single DSM installed in an Alpha CableUPS supports communications and system control for multiple Alpha power supplies and an AlphaGen™ generator system.
