Data Port Identification
When configuring the unit, menu selections will include
options from data port submenus. Selecting data ports is neces-
sary because the TSU 120 uses a slot-port method to identify
which data port the menu item is referencing. If a module con-
taining 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 TSU 120 are referenced as Slot
0 . The Nx56/64 would be designated as 0.1 and the DSX-1
would be referenced as 0.2.
