3.1
INITIATING A MOBILE TO LAND LINE CALL
A mobile to land line call can be initiated by using the following
sequence of operations:
¾
A global Connect Code is an access code used by all users of
the system. Key the proper global Connect Code; "*" plus two
programmable numbers, or a single "*".
¾
Unkey the transmitter and listen for a dial tone.
¾
After dial tone is received, dial the desired phone number.
¾
When the call is complete, dial the appropriate Disconnect
Code, which is a single "#"; or "#" plus two programmable
numbers.
3.2 LAND LINE TO MOBILE CALL WITH AUTO-ANSWER
This is a form of selectivo calling and requires the mobiles to be
equipped with a DTMF decoder. Dial the phone number of the line
connected to the CES Model SDI-50. If the channel is busy, the
interconnect will answer and give a series of three long beep tones;
then disconnect the calling party. If the channel is not busy, the
interconnect will answer on the programmed ring and return a single,
beep tone to the phone line. The caller shouid then enter the number
of the desired mobile; 1 to 5 DTMF digits terminated by a "#". The
interconnect will regenerate this number out to the mobiles as DTMF.
The mobile must answer with a "*", followed by the same number that
was dialed from the phone line. After the communication is completed,
the call may be terminated with the global disconnect from the mobile
or the phone line. If the mobile does not answer the call, the call
will be automatically terminated after the programmed wait period.
3.3 LAND LINE TO MOBILE CALL WITHOUT AUTQ-ANSWER
Dial the phone number of the line connected to the CES Model SDI-50.
The interconnect will detect the ring voltage on the phone line, key
the transmitter, and send the message programmed into the Error
Message area. The caller will hear the normal ring from the phone
company until a mobile answers the call. Any mobile may answer by
sending the global Connect Code. The call may be terminated from
either the phone line or the mobile after the call is completed by
sending the proper Disconnect Code.
3.4 INITIATING A DIAL-UP REMOTE CALL
This feature gives the caller dispatch capability and is available
whenever the SDI-50 is set up to automatically answer
