Intraplex Products
The ACS-166 and ACS-169 product packages each provide two T1 terminal multiplexers in a single
shelf. The multiplexers share the same power supply and alarm reporting system but are otherwise
independent; there is no communication between the two T1 circuits.
Note: Unless otherwise specified, all references to the ACS-163 multiplexer also apply to the ACS-
167 multiplexer, all references to the ACS-165 multiplexer also apply to the ACS-168
multiplexer, and all references to the ACS-166 multiplexer also apply to the ACS-169
multiplexer.

1.4.1 Main Equipment Shelf
The main equipment shelf is 19" wide rack-mount, 5¼" high for a 3RU multiplexer or 1¾" high for a
1RU multiplexer. This equipment shelf has slots for
● Plug-in common modules
● Channel modules
● Module adapters
● Power supplies
Warning! All common modules, channel modules, and power supplies must be inserted so that the
white eject tab is at the bottom in a 3RU shelf and at the right in a 1RU shelf.
