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.
