The XP-DSM remotely reports power supply data and alarms using the Simple Network Management
Protocol (SNMP) over the DOCSIS (Data Over Cable Service Interface Specification) communication
specification. The XP-DSM typically reports into a centralized Network Management System (NMS)
through a standard collection of data access points referred to as the SCTE-HMS Management
Information Bases (MIBs). The NMS polls the XP-DSM for power supply data with the option of
having the XP-DSM send SNMP traps in the event that an alarm condition is met. In addition to the
SCTE-HMS MIBs, the XP-DSM also supports the Alpha proprietary SNMP MIB (the Alpha MIB),
which allows direct access to the power supply as well as the ability to change transponder settings.
Power supply and transponder settings can also be viewed and set with a local PC via the local
port on the front of the XP-DSM (see Section 4.0 ). Transponder and power supply data can also be
monitored with an Internet Web browser.
