What does DPI offer over my current PC Card modem?

Ositech’s DPI technology is a complete connectivity solution! Like your current modem, you can connect DPI modems to analog phones. Most of the time you only have access to digital (PBX) phones (used in offices), which use a higher current than analog phones, and thus prevent you from making modem connections. Moreover, these higher currents can permanently damage your current modem.
With DPI, you are able to make fast, easy and reliable modem connections through digital (PBX) phones.


Is DPI the same as digital line protection?


No. DPI moves a step beyond simply protecting your modem. If you plug your modem into a digital wall socket, your modem will not be damaged. All Ositech modems come with Digital Line Protector ensuring your modem is never the victim of high current digital lines.
DPI moves a step beyond allowing fast and easy connections through the handset of digital phone systems.





Is DPI the same as external digital phone adapters?

Although external digital phone adapters provide the same access to digital phone systems, Ositech’s DPI solution is easier to use and less expensive. External digital adapters retail for approximately $150 US and require external AC power. DPI technology is built into Ositech modems and thus requires no additional power or accessories.


Can DPI modems connect to both analog and digital phones?




Yes! Ositech DPI modems can send data through analog phones, like the phones in your home, and through digital (PBX) phone systems, like the phones in your office.





What speed of connection can I expect when making a DPI connection?

DPI connection speeds are restricted to V.34 (33.6Kbps) because digital (PBX) phone systems include an analog to digital data conversion step that makes 56K connections impossible. Typical connection rates will range between 19.2Kbps and 28.8Kbps. Connections made in analog mode will result in 56K connections using either the V.90 or K56Flex protocols.


How do I make a DPI connection?

DPI connections are made through the handset of a digital (PBX) phone. To begin, you simply unplug the handset and plug the curly cable into the DPI coupler provided. Ositech’s special software first detects a DPI connection and then guides you through any necessary steps to complete the connection.
