Compact GSM Gateway with up to eight channels

With the new digital GSM gateway Ecotel ISDN2-2x, companies can significantly reduce their telephone costs. When connected to the private branch exchange (PBX), the gateway re-places expensive connections between the fixed network and mobile phones with economical mobile-to-mobile connections. At the same time, as an alternative to the DECT method (Digital Enhanced Cordless Tele-communications), the Ecotel ISDN2-2x makes it possible to use the PBX features “switching between calls” and “announced call transfer” from the mobile phones of the employees. In addition, the gateway makes it possible for mobile offices to connect via mobile phone networks. The Ecotel
ISDN2-2x is based on the proven Ecotel ISDN2-1x. The new system differs from the earlier one in that it has more GSM channels, intelligent local SIM card management (SIM switching), and SIM card server integration.

Lowering the phone bill
The most important feature of the Ecotel ISDN2-2x is the savings in tele-phone costs that it enables. When an employee calls a mobile phone num-ber, the connection is created via the gateway. In order to do this, the gateway has mobile telephone modules and SIM cards, and its own an-tenna. Depending on the network selected, the time of day, day of the week, and similar factors, the gateway automatically uses the SIM card that has the most economical mobile-to-mobile rate. Similar savings are realized for incoming calls. The Ecotel ISDN2-2x can be operated either at an inter-nal extension of the PBX or at its exchange (NT). It can be switched into the trunk line as a least cost router. That is, it is simultaneously connected to the PBX and to the ISDN trunk connection.

Mobile Integration
In addition, the Ecotel ISDN2-2x makes extension functions of the PBX available on the company mobile phones. If the employee mobile phones are connected to the telecommunication system via economical mobile-to-mobile connections, the functions of “switching between calls” and “an-nounced call transfer” can be used from the mobile phone. These functions are available independent of the manufacturer of the PBX and of the mobile provider used. “With the mobile integration functions of the
Ecotel ISDN2-2x, employees are easier to reach and have greater mobility,” explains Anton Glöckner, director of the MCC product line at Vierling. “This means that the gateway offers a simple, economical alternative to the stan-dard DECT solutions.”

Connecting mobile offices
Moreover, companies can use the Ecotel ISDN2-2x to connect mobile of-fices to the telecommunication networks via mobile phone. To do this, a number of phones can be connected to the gateway directly. Via the serial interface, PCs can use the Ecotel ISDN2-2x as a GPRS modem in order to gain Internet access. Faxes can also be sent and received via PC.

More channels, and intelligent SIM switching
The new Ecotel ISDN2-2x is distinguished from the proven
Ecotel ISDN2-1x by a greater number of GSM channels. The Ecotel ISDN2-1x offers a maximum of four GSM channels, while the Ecotel ISDN2-2x offers a maximum of eight. In addition, the new GSM gateway enables intel-ligent local SIM card management (SIM switching). That is, up to eight dif-ferent SIM cards can be used per channel. Depending on the day of the week, the time of day, or the capacity utilization of the SIM cards, the sys-tem uses previously defined rules to automatically select the best-suited card. In addition, the Ecotel ISDN2-2x can be integrated with the
Ecotel SIM card server (SCS) in order to access a central pool of SIM cards. “With the new features, companies are able to take maximum advan-tage of the potential savings that result from differences in fee structures,” says Glöckner.
