TOA Electronics CP-63 manual TIE-LINE Connection of the Exchanges

TIE-LINE CONNECTION OF THE EXCHANGES

1. Function of the Central Processing Unit CP-63

To make communications between exchanges possible in the EXES- 6000 system, the CP-63 and the Tie-line Interface Unit TI-62 are required in addition to the exchange EX-610 or the EX-620.

The TI-62 is the interface unit for transmitting and receiving audio signals and dial data signals between the exchanges.

After receiving dial signals from the station, the CP-63 transmits the dial data signals to the TI-62 and instructs it to make calls to the other exchange. The CP-63 also receives the dial data signals from the other exchange through the TI-62 and calls the station which is instructed to call by the other exchange.

Overall functions of the system using the Tie-line function are determined by programming made in the CP-63.
