Tie-line Connections of Exchanges
1. Purpose of tie-line connection
When the EXES-6000 system uses the Central Processing
Unit Model CP-63, not only the use of a single exchange
(up to 120 stations) but also the tie-line connections of
2 exchanges (up to 240 stations and without paging
functions) or 3 exchanges (up to 360 stations and with-
out paging functions) 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.
*1 The links within own exchange as well as the tie-line links are used in each tie-line communication.
*2 All call paging is provided to all the paging zones of all the exchanges connected by tie-line.
