CHAPTER 1 GENERAL INFORMATION
System Conditions
SYSTEM CONDITIONS
System Configurations
• The PIMs for the NEAX2000 IVS
2
/NEAX7400 ICS M100MX cannot be mounted together
with the PIMs for the former system.
• The Expanded highway for application processor cards can be used on PIM0 only.
• 8-circuit line/trunk cards cannot be used in 64-port PIM.
Expanded Highway
• The expanded highway is an additional 128 AP time slots made available to the system.
• The expanded highway can only be accessed from PIM0.
• EXAMPLE: System is currently configured with five T1s. Customer would like to add two
additional T1s to the system. The original five T1 cards will use 120 AP time slots
(24 channels × 5 cards = 120 AP time slots). The two additional T1 cards added to the
system would have to be the PN-24DTA-C cards. Room must be made in PIM0 to
accommodate the new PN-24DTA-C cards on the expanded highway. The system would
now have the original T1 cards using 120 AP time slots on the original highway and 48 AP
time slots used on the expanded highway.
• AP cards supported on the expanded highway are as follows:
• PN-24DTA-C, PN-24PRTA, PN-24CCTA, PN-SC03-A (CSH)
The above cards must be mounted in PIM0 in order to utilize the expanded highway. The
expanded highway allows up to 256 AP time slots per system.
