1.Purpose of tie-line connection

The EXES-6000 system incorporating the CP-66 central processing unit permits the use of a single exchange as well as the tie-line connection of 2 or 3 exchanges.

The tie-line connection is used when

1)connecting 2 or 3 exchanges installed in locations which are remote from each other (Maximum distance: About 2km. Cable: 0.65mm in diameter).

2)one more exchange, in addition to the existing exchange, is required for system expansion.
