system. The DECT Messenger system retrieves Incoming Alarms from IP DECT through this
TCP/IP port.
If a DECT handset needs to send messages to DECT Messenger, the extension number of
the handset must be IO monitored (IO Registered) in DECT Messenger. After an incoming
message is received by DECT Messenger from a handset, the message goes to a group that
contains devices. The incoming message is sent to all the devices specified in the Group.
Note:
The IP DECT system does not support sending a message from one DECT handset to
another directly. For sending a message from one DECT handset to another, you always
need a DECT Messenger system.
Incoming Confirmation (IC)
Incoming Confirmation is an LRMS (E2) message that is sent to an extension number (DNR)
in the DMC, and is used to reset an outstanding alarm on a device. The DECT handset from
which the LRMS (E2) message is sent, is monitored (IO Registered) by DECT Messenger. The
CLI of the DECT extension is used as identifier for resetting an outstanding Alarm on a Device.
The PIN code that is specified in the device settings must match this CLI of the DECT
extension. The message that the DECT extension sends is simply ignored.
The extension number to which the message is sent for IC can be a hardware-less Directory
Number (DN) in the DMC.
Note:
A message sent from an IO registered DECT handset to another DECT handset uses DECT
Messenger, with a Group-to-Group Member-to-Device structure.
Parameters required to set an alarm
The structure of DECT Messenger is based on five parameters that are required for generating
an alarm. Those five parameters can come from the input device. The input modules eAPI and
eCAP show that these parameters are required.
Figure 23: eCAP Sending Message option on
page 97 shows the Sending Message option of the eCAP generic, and shows the
parameters.
