QUICK USAGE GUIDE
This section presents a brief summary on how to place phone calls
through the EDACS Jessica system. For more information about the
access methods, refer to the detailed usage section.
MAKING PHONE CALLS FROM AN EDACS
RADIO
These "generic" instructions for all EDACS radios assume a typical
Jessica configuration. To determine the exact sequences to access Jessica
features from a specific radio, refer to the operator's manual for that radio.
The steps for making phone calls from an EDACS radio are presented
below.
Placing a Call
Initiate the call by one of the following actions:
1. Press the "*" key, enter the destination telephone number, and
then depress the PTT button.
2. Enter the destination telephone number, press the "*" key, and
then depress the PTT button.
3. Press the special call button (typically SCN or SCAN). Select the
telephone number from the list and depress the PTT button.
Common Speed Dialing
Consult your System Administrator for the common speed dial
numbers. Follow the steps for "Placing a Call" and use the common
speed dial number.
Answering a Call
Simply press the PTT button and hold while talking. Full duplex
radio users need only press PTT initially.

3.2. RADIO USERS
The chart below shows how to use a radio to accomplish several tasks
with Jessica.
Task Accomplishing Task with Jessica
Placing a PSTN
destination call
See your radio operator's manual for
specific usage on interconnect calls.
Number requires a Least-Cost Routing
(LCR) code as the leading digit of the
destination phone number. The LCR code
is customer-defined, but typically is "9."
Once the number is passed through Jessica
and into the PSTN, the radio user will hear
ringing.
Placing a PBX destination
call
Once the number is passed through Jessica,
the radio user will hear ringing.
Receiving a call To an EDACS radio user, reception of a
PSTN- or PBX-originated call involves
pressing the PTT button to answer it.
DTMF overdial Consult your radio operator's manual for
specific usage. Please refer to LBI-39000
for details on DTMF. DTMF is allowed in
clear voice only. Note: Currently, EDACS
radios generate the North American DTMF
tones. Therefore, to use overdial outside
North America, EDACS radios would be
required to generate the appropriate tone
set.
Terminating a call A radio-originated or PSTN- or PBX-
originated call may be terminated for a
radio with a keypad by pressing the SPC or
Clear button. Radios without a keypad may
terminate the call by not keying the radio
within the hang time period.
