D ata Port Identification
When configuring the unit, menu selections will include options
from data port submenus. Selecting of data ports is necessary
because the ESU 120e uses a Slot-Port method to identify which
data port the menu item is referencing. If a module containing a
PBX drop option card with an Nx56/64 plug-on interface is
installed in the option slot, it would be designated as:
drop Passthru=1.1
Where slot=1 and port =1.
The drop 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 ESU 120e are referenced as Slot 0.
The Nx56/64 would be designated as 0.1 and the drop would be
referenced as 0.2.
Front Panel Menu Structure
The ESU 120e uses a multilevel menu structure containing both
menu items and data fields. All menu operations and data display
in the LCD window.
The opening menu is the access point to all other operations. Each
Main menu item has several functions and submenus to identify
and access specific parameters.
