Tie-line Connections of Exchanges

Tie-line

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.

	Tie-line	Station
	Tie-line	(No. 200 ~ 455)
		(No. 200 ~ 455)
		Conversation
	Tie-line	Tie-line
	("C"-"A")	("A"-"B")

Conversation

Tie-line	Station
("B"-"C")	(No. 470 ~ 725)

Station	Station	Station
(No. 200 ~ 455)	(No. 470~725)	(No. 740 ~ 995)

2. Number of stations, paging zones and links

		Maximum number		Number of links			Maximum number	Maximum number of stations
						Number of		in each exchange

3 exchanges Tie-line			1	4 per Tie line		3	All stations calls	168	144
EX-3A EX-610		12*					+ 21 zones *4
	EX-620	16*	1	4 per Tie line		3	All stations calls	360	336
							+ 21 zones *4
EX-3B EX-3C	EX-630	16*	1	8 per Tie line *	3	3	All stations calls	768	768
							+ 45 zones *4

*1 Speech links of the local exchange are also used for communication between exchanges. *2 One (8 links) or two tie-line interface (TI-62) are required per exchange.

*3 Two tie-line interface (TI-62) are required per exchange.

*4 All-call paging from one exchange is placed over the whole area of all exchanges connected. *5 Different types of exchanges (EX-610/620/630) can be combined for tie-line connection.
