The UNIDA-1 (UNIversal Data Access) card supports the following data interfaces and meets all the requirements outlined below:-

• 4 off RS232, V24/V.28 interfaces
• Data rates:-
• 0.6Kbps to 38.4Kbps Sync/Async

With the UNIDA-1 it is possible to utilize the transmission facilities of the SDM to provide asynchronous as well as synchronous channels with low data rates to share 64Kbps time slots.

The UNIDA-1 supports 1 +1 protection to provide automatic switch over to backup transmission facilities
