Remote Access

The ASLH 306 modem has the ability to be remotely accessed for both testing and configuration purposes. This is achieved as follows:

1.Establish a normal dial up connection to the ASLH 306 modem.

2.Issue the “***” command to the modem from the remote modem.

3.The ASLH 306 will respond with an OK.

4.You are now connected to the remote 306 PIC interface.

5.If access to the Sony Ericsson module is required issue the AT+Z command

to the remote modem.

6.The ASLH 306 will respond with:

RC OK

7.Drop the dial up connection.

8.Re-establish the dial up connection again within 60 seconds.

9.You are now in communication with the Sony Ericsson module within the ASLH 306 modem.

10.Only AT commands proprietary to the Sony Ericsson module can now be used.

11.There is no method of returning to on-line mode following a remote access session and therefore the call must be terminated and a new call initiated.

Please note that the remote access feature only works when the modem interface is set for 8 data bits, no parity and 1 stop bit.

Pay As You Go (PAYG) SIM Support

This feature has been included as part of the solution to the requirement for the use of Pay As You Go SIM’s. PAYG SIM use demands that at least one phone call is originated from the number in a six month period in order to keep the service live. The meters used by the Electricity supply industry typically have no inherent intelligence, and therefore do not have the ability to originate a call to satisfy this requirement. This situation can be circumvented by use of a central site server designed to call the modems on a cyclical basis and instruct them to call into a pre-defined server number, which can be verified by the use of the CLI issued by the network provider. To this end the execution of the AT+T command causes the modem to dial an internally stored number automatically. This command can be executed both locally or remotely, ie. via the modem RS 232C interface or from a remotely connected modem. Once a connection has been established with the 306 modem the ***

command is issued from the remote modem causing the 306 to enter online command mode whereupon the AT+T command can be issued.
