Digital Access and Cross Connect System. A TSI switch that
switches DS-0 channels among DS-1 data streams. Computer controlled and
designed for keyboard
entry as opposed to automatic switching. There are many uses,
including semi-automatic test boards, digital circuit concentration, trunk
switching, and alternate
routing. The term "DACS" was extended for DS-0/ DS-1 switching but
has been applied to DS-1/ DS-3 switching. Many large "DACS" units include
combined
switching systems that allow DS-0 switching among DS-3s, always
with demultiplexing of the DS-3 data streams. IXC and LEC carriers offer
partitioned DACS service
under customer control, which allows the customer to control a
Virtual Private Network (VPN) within the carrier's network.
