The embedded Linux operating system and tools in the Cyclades TS devices are configured to pull the SMS messages from the modems and send to the NFS for storage. Processing can thus be properly balanced. SMS servers can choose an IP address among those assigned to the modems, open the connection and retrieve SMS messages. The message will be easily read either directly from the TS serial port or from the NFS buffer.

All modems are to stay connected to the network, actively retrieving and sending messages to guarantee a high quality of service. Downtime shall be kept to a minimum. The TS units monitor the modem for any abnormal condition, and in cases that require immediate attention, such as a modem initialization, proper corrective actions are taken without delay.

This solution remarkably enhanced the system design. TCP/IP technology has never been so appropriately used to achieve such a simple solution, yet with an incomparable better quality of service. Best of all, the cost was kept within the budget and changes to existing software were minimal.
