Vocality V100 ISDN Terminal Adapter (Link) Card

The ISDN Terminal Adapter is designed to work with Inmarsat GAN terminals or terrestrial ISDN networks. The card is available in three formats - Euro S/T, American S/T and American U Interface , and offers a dial up link connection of 64Kbps as well as a dual channel or bonded 128Kbps mode. The V50 and V100 are proven to be fully compatible with both the Inmarsat GAN network and equipment from the leading manufacturers of GAN terminals, including Thrane and Thrane, Nera and EMS Satcom.

Inmarsat GAN terminals offer a limited range of services : 1 voice/fax channel 1 data circuit 1 low speed packet data circuit None of the above can be used at the same time. By using a field deployable multiplexer, such as the V50 or V100, and connecting it to a GAN terminal, you can gain access to a wider range of services - all at the same time.

Bonding Multiple Inmarsat Terminals

This diagram shows that a user would need a third party "dual terminal bonder" such as a Scotty iSplit to combine two terminals before connecting to a Vocality ISDN device.
