Network Termination Units (NT1's) are required for each incoming BRI ISDN line.  The NT1 converts the 2-wire Central Office U-interface into the 4-wire S/T-interface used by the ISDN terminal at the customer premises.

NT1's

The industry standard B300 NT1 is used for stand-alone and rack-mounted applications. SEI's PoweRack 300e Series   is designed to provide integrated NT1 caging, power, and battery backup for B300 NT1's and associated telephones in either a rack or wall mounting.

The B300 NT1 can also be installed into an SEI 300R-U NT1 cage. This cage is compatible with 1145 power systems, or can be used with SEI's DP series.

For stand-alone applications, the DP20B series of products provides power and battery backup for up tp 3 B300 NT1's and 6 ISDN telephones.

The industry standard P230 NT1 circuit card is ideal for customers desiring high density.  The PoweRack 230e and PoweRack 96e provide integrated caging, power and battery backup for P230 NT1's and associated telephones. The P230 can be installed in a Lucent M-210 cage.

All SEI NT1's provide two status indicators, protection devices on all external interfaces, low power consumption, easily accessible configuration switches,  and multipoint capability. 

When purchased with a PoweRack, SEI will install and individually test each NT1, providing the customer with a fully configured solution suitable for immediate installation:

  • Pre-tested equipment that virtually eliminates out of box failures
  • Complete integrated package for reduction in installation time
