WIRING FOR TIE-LINE CONNECTION OF THE EXCHANGES

Each exchange can be connected by means of a cable with a diameter of 0.65mm (25.6 mils.) for a distance of up to 2km (5600 ft).

Regarding the tieline links which are not used, turn off the DIP switch of each unused tieline link inside the Tie-line Unit TI-62.

Connect "T" line (2 wires) of the 4 wires of each link to "R" line (2 wires) of the other exchange. The 2 wires of the "T" line and "R" line have no polarity.

If the BX-610/620 is used, its terminals No. 1 and 2 are for the "R" line and No. 3 and 4 are for the "T" line.

1. Wiring for tie-line connection of 2 exchanges

Exchange "A"	Exchange "B"
EX-2A	EX-2B

Note 1. Any combination of tie-line links between exchanges "A" and "B" is possible. But, in conside- ration of possible increase in the number of exchanges to be connected from 2 to 3 in the

future, we suggest you connect (link No. 0, 1, 2, 3) of exchange "A" to 6, 7) of exchange "B".

2. Wiring for tie-line connection of 3 exchanges

Exchange "A"

EX-3A

Exchange "C"

EX-3C

Note 2. Be sure to connect

Connection of to

Exchange "B"

EX-3B

(link No. 0, 1, 2,3) to (link No. 4, 5, 6, 7) between the exchanges. will lead to failure of proper operation of the system.

3. DIP Switch selection

DIP Switch

1.Switching arrangements of DIP switches (E-1, E-2, E-3) in the CP-63 make each exchange to be of "EX-1" or "EX-2A" or "EX-2B" or "EX-3A" or "EX-3B" or "EX- 3C" type.

2.In the event of the tieline link not to be used, turn off its corresponding DIP switch on the TI-62 unit.
