NI / 5E Custom Terminal Installation
INSTALLING THE
TERMINAL
ISDN equipment may be installed in a number of
configurations. In most installations, the
supplementary equipment (NT1 and power) is
located in a wire closet in your building. If this is
the case in your installation, please skip to the
section “Connecting to the network”.
In some installations, the NT1 and power are
located at the user’s desk.
Two drawings are included that illustrate the
connections you may need to make when the
power and NT1 are located at the user’s desk.
Figure 5-1 illustrates the connections when one
power supply is used for both the NT1 and the
terminal and also indicates the position of the power
switch on the terminal.
