115 VAC/-48 VDC Power Supply/Charger
The 115 VAC/-48 VDC Power Supply and Charger enables the Compact T1 to be
powered from either 115 VAC or -48 VDC sources, and includes an integral battery
charger and ringing generator. Integrating AC and DC power options, battery charger
and ringing generator functions in the Adi t c hassis dramatically reduces installatio n
time, space and cost requirements and inventory considerations in comparison to
separate power conversion or Uninterruptable Power Systems (UPS) equipment.
Front-panel LEDs provide easy-to-read indications of power input, battery status and
alarms. Remote notification to network operations and to monitoring centers of loss of
AC input or low DC input voltage is available via SNMP .
The ringing generator provides 25 Ringer Equivalence Number (REN) output,
supporting up to 48 FXS simultaneous ringing lines with normal cadence ringing.
Three ringer waveform shapes and three selectable ringer frequencies ensure
performance over a wide range of outside line or customer premises applications.
