SEI Power ISDN NT1 Racks and ISDN CPE Power |
SEI is the world's leading supplier of power systems for ISDN-based customer premises equipment. Their particular focus is the Customer Premise Equipment powering needs of digital Centrex telephony.
PoweRacks are specifically designed for the
Lucent B-300 NT1, P-230 circuit card and D-300 12-pack. Integrated NT1 caging, DC
power, battery backup and cable distribution are assembled in a footprint as small as
19x14 inches. Installation time is virtually eliminated!
The PoweRack is available in a variety of models depending on the number of phones, NT1
type and the battery backup time desired.
| The PR300-U is an enhanced version of the PoweRack 300R. This a premises powering unit that integrates NT1 caging, 48 volt DC power, and battery backup in a single unit for powering ISDN telephones and Lucent B-300 NT1's or equivalents. The PR300-U is available in four models that house and power 12 to 48 NT1's and provide power for 24 to 96 phones in a multipoint mode. In addition, the 24 and 72 line versions of the PR300 are field upgradeable by adding a 300R-U NT1 cage. The PoweRack 300-U can be either wall or rack mounted. The small footprint and simple installation of the PR300-U allows a cost-effective installation without the requirement for punchdown blocks (an optional wiring harness is available to facilitate NT1 input cabling). Battery holdover can be increased by adding external battery packs. 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 is provided by a contact closure that can be interfaced to a remote alarm unit. |  |

| The PR230
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 Lucent P-230 circuit card NT1's
or equivalents. The PR230 is available in two configurations. The PR230-24 will house and power up to 12 P-230 NT1's and provide power for up to 24 phones in a multipoint mode. the PR230-48 adds additional caging to house and power a total of 24 NT1's with power for 48 multipoint phones. Note that the PR230-24 can be field upgraded to PR230-48 capacity via an SEI 230R NT1 cage. For both PR230 models output distribution is accomplished using 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. Dual load-sharing rectifiers offer redundancy, while additional external battery packs can be added at any time for increased standby time. 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 is provided by a contact closure that can be interfaced to a remote alarm unit. The PR230-24 can be utilized to provide power to legacy NT1 cages such as the Lucent NT1M-210. Additionally, a stand-alone 230R expansion cage may be powered by third party 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). |

All power to the terminals and NT1s are protected by solid state thermal fusing.
System operation is maintained after loss of commercial power by the companion BP180
battery packs, which slide on to the PR180 and fasten to the wall or rack. During
extended periods of utility outage the batteries are protected from over-discharge by the
built-in low voltage detector and disconnect circuit. The PR180 comes with an
integrated battery test feature; remote monitoring is provided by a contact closure that
can be interfaced to a remote alarm unit. 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). |
