Nautica 250 Installation Guide
As an alternative to using SDS, you may configure the Nautica
250 to make (and/or receive) data calls using voice bearer
services. This can result in both local and long distance tariff
savings, and you do not have to inform your long distance phone
company that you wish to send data. The disadvantage of doing
this is that it is not guaranteed to work, because voice calls are not
always sent over data-grade circuits, and the data rate is in any
case limited to 56 kbps per channel. On the other hand, it usually
works, and it is compatible with the equipment used my most
Internet Service Providers and other organizations supporting
remote access.
