D) Insert the Modules.
Insert the reversible, color-coded BRI modules in the shown
slots. The selected mode should face outward and be
readable through the “windows” on the daughter card.
Insert the FXO or FXS module into the analog slot.
* When using FXS, you must attach a Molex Power Connector from your
computer’s power supply unit. This is also recommended when using FXO,
but it is not necessary.
** If you plan to use BRI phones, you must also connect a standard power
supply to the Power Feeder.
E) Set Termination Resistors.
(Use a paperclip or pen.)
When running in
TE mode
, ensure both termination resistors
that correspond to the module are set to
OFF
.
(See SW1 in diagram.)
When running in
NT mode
, ensure both termination resistors
that correspond to the module are set to
ON
.
(See SW2 in diagram.)
You must switch all termination resistors that correspond to
each module.
C) Determine which BRI ports you wish to run in
TE Mode
or
NT Mode
.
See diagram below for the corresponding ports and module slots.
Red =
TE Mode
Green = NT Mode
