 The NT1B-300TC is a compact ISDN Network Termination suitable for standalone or rack configurations. Terminal equipment (typically ISDN telephones) can be powered through the NT1. Power is provided by an in-line desktop power supply or by the rack.

Both point-to-point and multipoint ISDN terminal equipment configurations are supported. This unit may be used as a drop-in replacement in Lucent NT1B-300 applications, and is compatible with the Tone Commander NT1B-300 Rack, Lucent NT1B-310 Rack, and SEI PoweRack PR300e.

Unique features of the Tone Commander NT1B-300TC:

  • Front edge S/T modular jacks for patch panel access
  • Termination resistor can be set/verified without removing NT1 from rack
  • Slim front profile facilitates insertion and removal in high-density rack
  • Power jack for low-cost standalone power supply

Standalone NT1s can be locally powered by the -PWR1 (recommended), -PWR2, or -PWR3 Power Supply options, or remotely powered by the PS-50 ISDN Power Supply. Power supplies are available separately.
