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-1would be referenced as 0.2.
