5.5 Selective Call Answer
Not for INSYS Modem LL.
If the selective call acceptance is activated, the modem
will only accept calls from certain callers. The identifi-
cation of permitted callers takes places via the caller ID
transmission (CLIP). This must, however, be supported
by the phone system or the exchange connection,
where the modem is connected to.
