ENIGMA XM88422 Digital Receiver
Version 1.50
25
In stand-alone mode, it is possible to enter the Line
Cards own menu for programming, which function is
disabled in normal operation.
After the CPM Unit is replaced or reset, and polls the
Line Card normally, the Line Card returns to stand-by
mode, and displays the following:
Line #01
CPM Restored
Call Reception
When a call is received, the Line Card first indicates
the ringing on the phone Line
Line #01
Ring...
If caller identification is enabled and a valid Caller ID
is received between the first and second rings the
Line Card will display a message similar to the
following:
ID: 0630400543
Ring...
In the first row of the screen now the calling number
is displayed with area code. The calling number is
also transmitted to the CPM Unit. If no valid Caller ID
is received, this display will not be seen.
After the programmed number of rings received the
Line Card will pick up the line, the Comm LED will
light up and on the screen appears:
Line #01
Incoming call
Or, if a valid Caller ID has been received:
ID: 0630400543
Incoming call
The Line Card issues the handshakes in the
programmed sequence and waits for response. If a
digital dialer responds to a handshake, a similar
display will appear:
In communication
>12342756F
By decoding the received data, the Line Card
determines which format of the Format Library fits for
the received sequence. After a valid message is
received and decoded, the event will be forwarded to
the CPM Unit and the current communication format
and the decoded data will be shown:
Ademco Express
1234 56
If there is an error in decoding the type of the error
will be displayed along with the received data for
review and a “Fault Data” message will be sent to the
CPM if debug mode is enabled.
Bad CRC/Checksum
>12342756E<
The
following
possible
error
conditions
are
recognized by the Line Card:
Repeat fail
Bad CRC/Checksum
Unknown format
Note that although the Line Card can automatically
identify most of the formats, some of the
communication formats must be enabled/selected by
programming.
2-way Audio Mode
There are two methods of activating 2-way Audio
mode. The first is the direct activation by special
event types defined in sophisticated communication
formats like Contact ID, SIA and CFSK. These
formats have predefined event codes for listen-in
request. If the proper code is received, the Line Card
will activate 2-way Audio Mode.
The other possibility is to define certain account and
event groups to engage 2-way Audio that allows the
extension of listen-in to 3/1, 4/1, 3/2, 4/2 etc. formats.
In this case, the first digit of the account code
specifies the range of accounts that are able to
activate 2-way Audio, and the first digit of the event
specifies the range of events that can activate the 2-
way audio mode when received from the proper
accounts.
When the 2-way Audio Mode is activated, the Audio
LED will light up and the handset connected to the
Line Card will be active (See Chapter 3. Installation).
The LCD will show:
2-way Audio Mode
<CLR> to stop
The operator now can talk to the calling party with the
handset. The Audio Mode can be finished by the
operator by pressing the CLR button. If the 2-way
Audio Mode timeout is programmed, the Line Card
will disconnect the handset after the timeout period
expires, even if the operator has not pressed the CLR
button.
Call Termination
The call is normally terminated if there is no more
communication attempts after the last event received.
