Data Port Identification
When configuring the unit, menu selections will
sometimes include options from data port menus.
Selection of data ports is necessary because the TSU
120 uses a Slot.Port method to identify which data
port the menu item is referencing. For example, the
base unit is slot zero (0). Anything in the option slot is
referenced as Slot 1. If a module containing an OCU
DP option card with an Nx56/64 interface is installed
in the option slot, it would be designated as:
OCU DP=1.1
Where slot=1 and port =1.
The OCU DP is located in option slot 1 and is the
first port in that slot.
Nx56/64=1.2
Where slot=1 and port=2.
The Nx is located in Slot 1 and is the second port in
that slot.
