This document details how to install an analog modem in Alert. 
When configuring a GSM modem, the default SMS format is set to "Auto". In this case, Alert manages the best format for sending SMS according to the two formats (text and PDU) supported by the modem.
By default, the preferred format is PDU. This format allows you to access all GSM features.
The text format is a format used for testing.
When sending an SMS we recommend putting the number in international format in the configuration of the operator. Ex: +33 6123456 (without the 0)
However, internally, the Alert software automatically adds the country code associated with the operator if the number is more than 8 characters.
You have 2 options:
- The extension of the GSM antenna cable which can be 30 meters or more depending on the shielding of the cable.
- RS-232/IP or USB/IP converter. We have tested several converters RS-232/IP and USB/IP.
With these types of converters you can install the GSM modem on the same IP network as the Alert server, but located where the GSM signal is better. You can then use it as if the GSM modem was next to the Alert Server
Activate the extended error report (with AT+CMEE=1) to get the error code and check the error cause in your AT commands manual.
Possible causes :
- SIM or SIM holder not properly inserted
- Lock of SIM connector is not locked (see SIM card lock feature)
- SIM failure
- defective SIM card reader, lSIM not recognized (5V SIM with a modem/module compatible with 3V SIMs only).
You can also activate the +WIND unsolicited by keying AT+WIND=1 for example. This command in this case of use gives the indications of a physical change on the SIM presence pin from connector meaning SIM inserted, SIM removed. Check the error code returned in the AT commands manual.
The GSM TS 04.08 specifies that if an incoming SMS arrives when trying to send an SMS; the outgoing SMS could be rejected.
There are 3 possible causes for getting a +CMS ERROR: 513
- The MS (Mobile Station) loses the radio link (or the network requests an RR disconnect)
- The MS (Mobile Station) does not receive the acknowledge from the network (CP_ACK) about 28s after the transmission of the Short Message data (CP_DATA)
- The MS (Mobile Station) does not receive the acknowledge from the network (CP_DATA(RP_ACK)) about 42s after the channel establishment request
This error is sent by the network when the Service Center Address is wrong, or when the destination address is wrong. This error means that the SMS has been actually sent by the module (well formatted) but it has been refused by the network (the remote number is not a GSM one, the Service Center is wrong, the service is not available, DCS not supported ...) -> the customer should then check the information send in the SMS.

To acknowledge alarms upon receiving an SMS in Alert, you need a GSM modem and you need to use a specific script.
To install this script you must follow the AckAlarmSMS ReadMe.txt file in C: \MMI \ Alert
