9. Making a telephone interconnect call

If a base station transceiver is linked to an IPC-500 telephone
interconnect unit (figure 9.1), it can make and receive telephone
calls through the public switched telephone network (PSTN).
Using the selective call facility on your outstation Radiophone to
signal the base station telephone interconnect, you can dial any
telephone number of up to 16 digits. The number is sent as part
of the selective call signal.
Your outstation Radiophone can store up to 10 pre-programmed
telephone numbers which can be recalled for 'abbreviated
dialling'. In addition, your outstation Radiophone can receive a
selective call containing a telephone number which can be stored
and reviewed later.
When the telephone mode is enabled, P-channels P90 to P99 are
used for storage of telephone numbers with the base station
telephone interconnect facility. These channels are no longer
available for general use with channel frequencies.
