DSX is sized right, starting with the economical 40-port DSX-40, growing into the 80-port DSX-80, and
culminating in the 160-port DSX-160. To maintain the value of your investment, all the components of a
DSX-80 can be used in DSX-160 just by adding a DSX-160 cabinet. Even when growing from the DSX-40,
your investment in programming, telephones and other station equipment is retained.
