1.0 Introduction to the DOCSIS® Transponder
The IDH3 Transponder for the XM2 power supply manages network powering through existing cable
modem or high speed data infrastructure. A single transponder can monitor and manage multiple
power supplies, multiple strings of batteries, and one generator. The transponder transmits data
to a management system via the existing DOCSIS network. SNMP (Simple Network Management
Protocol) keeps bandwidth use to a minimum. Status monitoring data is compatible with ANSI/SCTE
HMS (Hybrid Management Sublayer) standards.
With optional VoIP test functionality, the power supply transponder becomes a powerful network
diagnostics tool. Contact Alpha Technologies for more information.
Outstanding Features:
• Uses existing headend DOCSIS CMTS equipment.
• Uses ANSI/SCTE HMS standards.
• Single transponder supports up to six power supplies, two battery strings, and one generator.

1.0 Introduction to the DOCSIS® Transponder, continued
1.1 System Overview
The IDH3 Transponder obtains data from the EDSM (Enhanced Digital Status Monitoring)
interface card through an XM2 Power Supply. The EDSM collects data directly from the
battery strings or from the AlphaBus Communications Network, depending on system
confi guration.
Equipment monitored (direct battery monitoring):
• An XM2 Power Supply
• One or two 36Vdc or 48Vdc battery strings
• One AlphaGen stationary generator system (if installed)

Equipment monitored via the AlphaGuard™:
The AlphaGuard performs electrical compensation for differences in individual batteries in
the string. The unit can be confi gured to pass measurements from the battery string to a
status monitoring device (EDSM card, DOCSIS transponder, etc.) via an interface cable.
