The NT1-296 Rack is designed to be used in conjunction with
Tone Commander NT1U-223TC ISDN Network Termination
cards. A maximum of 16 cards can be used in each rack.
Each NT1U-223TC card contains three NT1 circuits, with support for two
terminals per circuit. A fully loaded rack has a maximum capacity
of 48 NT1s and can support 96 ISDN terminals.
The rack supplies power to the NT1 units, and terminal
equipment connected to the NT1s, from a local 120
VAC outlet.
Optional NT1-200/296 Battery Backup Power Supply
and NT1-200 Add-on Battery can be added to the rack to
enable uninterrupted NT1 and ISDN terminal power during a
power failure. A fully loaded rack will operate for 1 hour with the
