Tie-line Connections of Exchanges

1.Purpose of tie-line connection

When the EXES-6000 system uses the Central Processing Unit Model CP-64, not only the use of a single exchange (up to 256 stations) but also the tie-line connections of 2 exchanges (up to 512 stations) or 3 exchanges (up to stations) are possible.

This tie-line function may be used when

1)You wish to connect 2 or 3 exchanges in the remote areas (maximum distance connected between ex- changes using the cable of 0.65mm diameter is approximately 2 km.)

2)One exchange is not sufficient enough to cover the desired number of stations and a separate exchange is required for increase in the number of stations.

*3 Two tie-line units (TI-62) are needed per exchange.

*4 All call paging is provided to all the paging zones of all the exchanges connected by tie-line.
