Message input

The following input can generate messages in DECT Messenger:

•

ESPA 4.4.4 pager protocol: DECT Messenger can receive pager

messages from ESPA 4.4.4-compatible pager equipment.

• RS232/V.24 serial input: many protocols are supported as input for

generating a predefined message or a free message.

•

DECT handset with E2 (Low Rate Messaging Services [LMRS])

messaging.

• E-mail the DECT Messenger server PC: send a message by e-mail

to a telephone set, SMS to cell phone or any other output on DECT

Messenger.

•

Switches (push buttons, toggles): message alerts generated by alarm

contacts, door contacts, fire contacts, and so on.

•

Analogue voltage/current levels: this form of message generation is

used to guard industrial equipment. For example, equipment output

messages can be pressure indication, temperature, and so on.

•

Web interface from which you generate messages manually.

•

Programs you write that communicate (using TCP/IP socket) with

DECT Messenger: DECT Messenger provides a port on TCP/IP that is

open to receive input data from this type of unique program.

•

Calling a specific telephone number. In this case the extension number

that is dialled in combination with the originator telephone number (CLI)

is used to generate a predefined message.

•

An SNMPv1 or SNMPv2c trap can generate a message.

Message output

DECT Messenger supports the following output:

•

DECT E2 messages (up to 160 characters)

Although DECT Messenger supports up to 160 characters, the DECT

equipment or the handset can limit this to 128, or even 48 characters.

If the handset supports only 48 characters, the message is broken into

sections and sent in parts to the handset.

• Messages sent to Ergoline or DECT extensions during ringing and after

a call is connected.

The first part of the message is sent as an alert phase. The remaining

part (if there is more) is sent in call connect status.
