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.
