1. GENERAL
This manual provides circuit card descriptions for the NEAX2400 IPX system.
This manua l is for th ose person s invol ved in syst em setup and a dministr ation activ ities f or the NEAX2400 IPX.
For each circuit card the following items are explained:
• General fu n ct i o n
• Slot to mount the circuit card
• Precautions for mounting the card
• Locat i o n of the electro n i c devi ces on the card surf ace
• Descripti on of t he L E D
• Description of the switches
• Phys i cal i n terface
The circuit cards explained in this manual are divided into two categories, the Control Circuit Cards and the
Line/Trunk Circuit Cards. You can easily define the card category by the pull tab color of the circuit card.
• Control Circuit Card
White or red pull tab circuit cards are categorized as control circuit card. Also, the circuit cards in the
Central Processor Rack (CPR) have white or red pull tabs.
• Line/Trunk Circuit Card
Blue or yellow pull tab circuit cards are categorized as line/trunk circuit cards.
Note: This manual is intended to describe only the basic line/trunk interface circuit cards of the NEAX2400 IPX.
When you use circuit cards not shown in this manual, you may refer to the NEAX2400 ICS Circuit Card
Manual with the following changes:
• The line/trunk circuit card shown in the above mentioned manual is compatible with NEAX2400 IPX;
however, the exceptions are PA-CS02-C (2AT1) and PA-CS08B (H/MATI).
• The exte rnal appearance of PIM U (which is the standard port interface module of NEAX2400 IPX) is
the same as the PIM J of the NEAX2400 IC S.
• The PCM highway running in PIM is different. More details are explained in this manual’s s ection on
PH-P C36 (MU X ).
