toll restriction invoked on the telephone number dialed. The records stored internally in the
Model 748 may be retrieved with any XMODEM-capable communications software and written
to an ASCII text file. To help maximize the value of data that is stored internally, this option
allows you to control or filter out which records are stored, both at the user and system level. All
calls are always logged out the local RS-232 port in real time. On a system with heavy use, this
means downloading less often. The maximum number of records that can be stored is 4000.
Voice Prompts Option
Any version of the Model 748 may be equipped with the Voice Prompt Option (950-9588). This
option has 9 voice messages that give call progress information to the caller. These include two
Welcome/sign-on messages (one for Telco and one for Mobile to Mobile), invalid user ID,
restricted user, unable to complete call, proceeding with the call, start talking prompt, channel
busy, and channel ID. The system operator can record any or all of the messages that pertain to
his system. Experienced users can bypass the messages by entering the DTMF overdial at
anytime.
Dial Click Option
Any version of the Model 748 may be equipped with the Dial Click Decode Option (950-9589).
This allows support of older telephone systems that have a mix of DTMF and rotary or pulse
dialing. The decoder board converts the residual clicking of the old style dialing into numbers
that the Model 748's microprocessor can deal with.
Kit Options
These kits provide alternative interface hardware for those who require them to match their
equipment.
