Chapter 1 – Description and Specifications
ProductDescription
The Multi-Tech MultiModem ZPX is an internal universal PCI bus card, MT9234ZPX-UPCI or a PCI Express bus
card, MT9234ZPX-PCIE. The UPCI card operates in either 3.3 or 5V slot. The PCI Express card operates in a 3.3V
slot.
The MultiModem provides high-speed data transfer and fax capabilities for small businesses, telecommuters, and
SOHO users. It is compatible with the IUT-T V.92 protocol that provides quick connections, downstream
transmissions at speeds up to 56K bps*, and upstream transmissions speeds up to 48K bps when connected to
V.92-compatible Internet service providers. Transmissions between the MultiModem and other 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 network.
* Though this modem is capable of 56K bps download performance, line impairments, public telephone infrastructure, and other
external technological factors currently prevent maximum 56K bps connections.
