The PR230e is a premises powering unit that integrates NT1 caging, 48 volt DC power, and battery backup in a single unit for powering ISDN telephones and SEI or Lucent P230 circuit card NT1's.
The PR230e is available in two configurations. The PR230e-24 will house and power up to 12 P230 NT1's and provides power for up to 24 phones in multipoint mode. The PR230e-48 adds additional caging to house and power a total of 24 NT1's with power for 48 multipoint phones. Note that the PR23e0-24 can be field upgraded to PR230e-48 capacity via the 230R NT1 cage.
PR230e output distribution is provided through standard 50 pin amphenol connectors which eliminate the need to use punchdown blocks. All power lines to the terminals and NT1's are protected by solid state thermal fusing. An automatic test circuit monitors battery performance and provides an alarm indication when the internal battery pack needs to be replaced. During extended periods of utility outage the batteries are protected from over-discharge by the built-in low voltage detector and disconnect circuit. Remote monitoring for AC power and battery performance is provided by a NC and NO contact closure that can be interfaced to a remote alarm unit.
The PR230e-24 can be utilized to provide power to third-party NT1 cages such as the Lucent M-210. Additionally, a stand-alone 230R expansion cage may be powered by legacy powering units such as the Lucent 1145.
All PR series units are mountable either on a wall or on 19" racks. Mounting brackets for 23" or 25" racks may be ordered as options (specify 23RM or 25RM after the model number).
