1. General Function
The PA-16ELCJ (ELC) circuit card provides an interface between the D
term and the IMX. Depending on
the switch settings, this card works in the following two modes.
16 ELC mode: A maximum of 16 sets of D
terms can be connected to this card (voice communications
only).
8 DLC mode: A maximum of 8 sets of D
terms can be connected to this card (simultaneous voice...

4. Lamp Indications
Lamp indications for this circuit card are shown in the table below.
Note:When the PALM lamp lights red, observe the following instructions. 
i) Identify the location where any in-house wires have a short circuit in all lines which belong to the PA-
16ELCJ card whose PALM is on. 
ii) Repair the short-circuited wires of the associated D
term.
iii) Disconnect the D
term from the rosette, then leave it...
