56 Kbps modem technology (3)
Before switching to 56K modem ...
- If we buy now the vendor should offer upgrade to eventual standard.
- And of course the full K56bps is available for download only. Upload of data is available at standard rates (max 33.6 Kbps).
- There are also other issues which should be taken into account (vendor, technology, type, upgradability to new standard, remote configuration and management)
- PC must be fast enough to keep up with the modem : it is important when data are compressed more than 2:1. The serial interface in PC (which usually is 115.2 Kbps can be too slow and must be accelerated.)
