conduct calls until the given amount of charge units are consumed.
Emergency numbers can still be dialed after depleting the charge account.

information that it receives from ISDN during the connection into charge
pulses that are used by analog terminal devices to display the charge.

TELES.ISDN device manager attached to the same ISDN line.
