  NT1B-300 Rack
   
  NT1B-300 Rack Click for larger image. The NT1B-300 Rack houses 24 Tone Commander NT1B-300TC ISDN Network Terminations in a 19" rack, 23" rack, or wall mount configuration. This rack is also compatible with Lucent NT1B-300 NT1s. It can be used as a functional replacement (without battery backup) for the SEI PoweRack PR300e-48, yet requires less than 1/3 of the vertical rack or wall space (5.2" vs. 17" high).

The rack supplies power to the NT1 units and terminal equipment connected to the NT1s from an integral power supply. 

The optional NT1-200 Battery Backup can be added to provide uninterrupted NT1 and ISDN terminal power during a power failure; operating time may doubled with additional NT1-200 Add-on Batteries.
