In the data mode, the modem allows data to be received at speed up to 56
kbps. Taking advantage of the PSTN, which is primarily digital except for
the central office local loop, this modem is ideal for remote access
applications such as Internet Service Provider, On-line service, or corporate
site. As a client modem, data can be sent at speed up to 31.2 kbps.
As a V.34 data modem, the modem operates at line speeds up to 33.6 kbps.
Error correction and data compression maximize data transfer integrity and
boost average data throughput up to 115.2 kbps.
