Data Port Identification
When configuring the unit, menu selections will include
options from data port submenus. Selecting of data ports is
necessary because the TDU 120e uses a Slot-Port method to
identify the data port the menu item is referencing. If a
module containing a PBX DSX-1 option card with an Nx56/
64 plug-on interface is installed in the option slot, it would be
designated as:
DSX-1 Passthru (1.1)
Where slot=1 and port =1.
The DSX-1 is located in the option slot and is the first port in
that slot.
Nx56/64 (1.2)
Where slot=1 and port=2.
The Nx is located in the slot and is the second port in that
slot.
The ports that are built into the TDU 120e are referenced as
Slot 0. The Nx/DBU is designated as 0.1 and the DS-1 is
referenced as 0.2.
