CALL PROCESSOR
5-3
5.3.6 KEYBOARD LOCK
The system operator has the ability to lock the
keyboard by password control to prevent the unautho-
rized use of the Call Processor. The password is a
single level of control.
5.3.7 LOG OUT/LOG IN
This function allows the operator to log out of
Call Processor thereby locking the keyboard from
unauthorized usage. Once the Call Processor has been
logged out, the function becomes Log In. The log in
function will ask for a password. If the password is
not correct, access is denied.
5.4 ALARM CONTROL
The alarm control is where errors are time
stamped and passed to the activity log function and the
message accounting output function.
5.5 SYSTEM ANALYZER
The Call Processor has the ability to perform an
analysis on the system. This is a complete handshake
(interrogation) of a test mobile in the RF coverage of
sites. This verifies the correct operation of the system
to and from the mobile. The analysis includes all links
including the antenna systems and RF coverage. The
system analyzer has the ability to automatically
disable channels from the system that do not pass the
analysis.
5.6 CALL PROCESSING
The Call Processor processes Unique ID calls,
telephone calls and group site calls (see Call Sequence
Appendix B). Normal dispatch call processing is
handled independently in the associated modules.
The Call Processor determines if an originated
Unique ID call is to be automatically routed or not and
routes the call to the appropriate facility, i.e. DIM or
SNM. The destination Unique ID call is processed by
the Call Processor to determine routing to a DIM or
CIM. Both origination and destination calls are
accounted for and a message accounting record is
generated.
The dialed digits of an incoming telephone call
determine the Unique ID requested and the Call
Processor routes the call to where the Unique ID is
registered. The Call Processor determines if the
Unique ID on an outgoing call has the proper permis-
sion for the digits dialed, selects the proper trunk, and
creates a message accounting message.
The group site call is routed to the site selected on
origination and creates a message accounting record.
The Call Processor uses the information from the
SSB to validate the use of the system for audio on
Home repeater channel, Group ID sets and Unique
IDs. If an unauthorized user is detected, the Call
Processor intervenes and disconnects the audio being
transmitted from the modules or mobiles.
