Recall function on the CO line (i. e. for use with call waiting)
In case of a CO-line connection, the telephone system intercepts a flash-signal (R-key) which
therefore is not transferred to the external line. In order to send a flash-signal from a telephone
to the public exchange, this has to be set accordingly within the telephone system before.
The function is only available for a DTMF phone.
The flash time of the telephone has to be below the maximum loop interruption time for the
termination of a connection by the public exchange. The maximum loop interruption time is
500 ms.
