102 DECT Messenger Customer Engineer Manual

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 22 "eCAP Sending Message option"

(page 102) shows the Sending Message option of the eCAP generic, and

shows the parameters.

eCAP Sending Message option

Not all input devices are capable of generating all five input parameters. If

parameters are missing (for example, if a switch is connected to the eIO

module), the parameters are taken from fields in tables.

The following five parameters are needed.

• *SET/*RESET

This is described in “SET/RESET structure” (page 108).

• Group

The Group is used to define the destination. The Group contains group

members, each of which is a device.

Note: This requires that the Group must be defined in DECT

Messenger, otherwise an alarm for a certain group comes in but

there is no group specification, which means that the alarm cannot

be delivered.
