Dear Keystone supporter,
Our February edition of the newsletter features some new appointments at Keystone, as well as a case study on
the development of an E1 Redundancy Switch for an SMS server for one of the leading cellular service providers.
Although used for the SMS server in this application, the E1 Redunancy Switch can be used for any system requiring
a fail-over solution.

CASE STUDY
Keystone Develops E1 Redundancy Switch for Leading GSM Service Provider
Keystone Electronic Solutions has developed an E1 redundancy switch for an SMS server for one of the leading GSM service providers. Part of the requirement for the SMS server was to have a safe fail-over system in case of server failure, as well as to ensure line integrity and therefore guarantee the delivery of the messages through the server.

Ivan Popov, Keystone director, explains: "At the boundary between the various service providers, there is a server that processes and routes the SMS signals. It has monitoring software installed on it, such as spam filtering, amongst others. You can imagine that if this server were to go down, there would be a lot of angry customers who sent vital SMS messages that were never delivered."
"Our electronics design team was able to develop a real-time fail-over switch to a stand-by server, or in the case of a total system failure, it bypasses the monitoring system completely," he says.
Thanks for your support
