19 " racks for PSTN & GSM: proven technology still up to date!

19
Bausch Datacom continues offering 19" modem rack systems based on the PSTN Proxima and GSM Indubox modem technology. High performance and reliability are the key features of this modem technology.

The development of PSTN & GSM rackmodems continues to be integrated in the Bausch Datacom portfolio. Often, a managed 19" rack for dial-out applications is still used all over the world. However, because many leading manufacturers are more and more stepping away of the circuit switched technologies, products are more and more difficult to find. Bausch Datacom is trying to fill this gap. The Proxima rackmodems are integrated in a 19 inch rack for maximal 16 x Proxima PSTN or 10  x GSM Rack modemcards including power-supply  & modem management system through a Digi terminal Server. This allows TCP/IP and SNMP communication and management. An antenna combiner collects the rackcards to a single antenna for transmission. A spare power supply is available. For project purposes, customers can buy a sample rack at project price to evaluate the application.

The rackmodem cards are based on the Bausch Datacom modemtechnology using for PSTN Conexant chipsets and for GSM Sierra Wireless. As we use our own technology in the racks Bausch Datacom is able to offer special features such as leased line (PSTN) and others.

Proxima GSM 19" rack
Recently Bausch Datacom relaunched the Proxima GSM 19" rack, a GSM version of the PSTN rack. A typical set up and application is the following: A terminal server solution (Bausch Datacom suggests Digi) offers a TCP/IP connection and SNMP managmement to the 19''Rack with maximal 10 GSM Proxima rackcards based on Sierra Wireless GSM modules. The rack is powered by an internal Power supply, a spare Power Supply is available and the 10 rackcards end on a SMA (female) connector. An antenna combiner collects the GSM modules to one GSM Antenna. This simple solution allows the customer to manage from it's (TCP/IP) network a circuit switched racksolution for dial-out applications.
