to one or more DMC units for eDMSAPI. If the DECT handsets are in more

than one unit, you can use an eDMSAPI module on one PC, or you can

install eDMSAPI modules on other PCs as well.

The External Application Interface (EAI) – used for LRMS messaging with

the web or external applications – supports normal, urgent and emergency

messages. In previous releases the SNDEMSG was not available.

The EAI also supports LRMS messages up to 160 characters in length

when messaging with SIP DECT. The EAI only supports LRMS messages

up to 48 characters in length when messaging with the DECT Messenger

CPU.

eIO

The eIO module is an input and output module that requires specific

additional hardware from National Instruments. If no COM port in the PC

is available, a multi-IO board is required. The additional hardware uses

an RS-232 connection. The eIO module connects external hardware

to the Nortel DECT Messenger. Use either digital or analogue input

devices for alarm generation. These devices connect to the National

Instruments panel. The panel informs the eIO module of the presence of

DECT Messenger. Switches, motion detectors, or fire detectors are used

as input devices. Voltage or current levels are used as analogue input

devices. An alarm is activated based on the level of the voltage/current.

You also use the National Instruments panel to switch external hardware

on or off when the output component of the eIO module is being used.

More information on the National Instruments panel can be found on the

National Instruments web site (www.ni.com).

eSMTP

The eSMTP module is an output module. Use it to send e-mail alarm

messages to a specific e-mail address. To send e-mails, you must enter

the IP address of an SMTP-protocol e-mail server on the network. An

e-mail message is sent to one e-mail address only. No option exists to

send the same message to multiple e-mail addresses simultaneously,

although you can send the same message more than once to different

e-mail addresses. The subject of the message is alarm message, and

the body is the alarm message. An SMTP mail server is not included in

the eSMTP module because eSMTP behaves as an e-mail client sending

e-mail messages.

eSMTP_Server

The eSMTP_Server is an input module, and is not an SMTP or mail

server. This module must be used in conjunction with the Internet

Information Server (IIS). The IIS is a Windows 2000 component that is

automatically installed with Windows 2000 Server. In Windows 2000

Professional, the IIS must be separately installed. Alarms are sent based
