Chapter 1—Introduction and Description

network typically is converted from digitial to analog only once before it reaches your modem. Upstream transmissions and transmissions between client modems are limited to 33.6K bps, as are upstream transmissions to non-V.92-compatible ISPs and downstream transmissions that are converted more than once on the telephone line.

Note: Though these modems are capable of 56 Kbps download performance, line impairments, public telephone infrastructure, and other external technological factors currently prevent maximum 56 Kbps connections.

Modems on the ISI5634PCI card are Plug and Play capable with interactive automatic dialing and command mode configuration. In standard mode, you can store up to three command lines or telephone numbers of up to 40 characters each in the modems’ nonvolatile memory. The modems pulse- or tone-dial and recognize dial tones and busy signals for reliable call-progress detection. The modems can detect AT&T calling card tones. They also have DTR dialing, remote configuration, 11-bit capabilities, and incorporate self-resetting lightning protection. Serial port speeds can be set to 230,400 bps. They are both FCC registered for connection without notification to the telephone company.

The ISI5634PCI card has full-duplex intelligent modems with V.42 error correction, V.42bis and V.44 data compression, and “Super G3” ITU-T V.34 fax communications at speeds up to 33.6K bps with Class

2.1fax commands. Voice functionality (+V commands) has also been added to the features of ISI5634PCI modems.

The ISI5634PCI is a multiport serial port expansion card that adds data buffering on each port for enhanced serial port performance. The ISI5634PCI features an on-board microprocessor to coordinate the communications activity of your local and remote terminals. Using the ISI5634PCI to provide additional serial connections enables your system’s processor to perform more efficiently since the ISI5634PCI handles all byte-by-byte interrupts generated by asynchronous terminals and stores the data in buffers.
