Description

Each MT2834MR card has three integrated 33,600 bps MultiModems. Each of the three modems on the
MT2834MR card can be configured independently from each other via the MultiCommManager (Model
#MR4800). The rack can support and control up to 16 MultiModem cards, to a total of 48 modems per
rack. Up to 254 racks can be networked, for a total of 12,192 modems on the network under control of a
single PC. Refer to your MultiCommManager Owner's Manual for more information on the rack and its
components.
Perhaps the most significant extras incorporated in the MT2834MR are its V.42 error correction and
V.42bis data compression features. With error correction and data compression, transmission errors are
eliminated while increasing the modem's throughput by a ratio of up to 4:1, for an effective overall
transmission rate approaching 115,200 bps.
The MT2834MR offers interactive automatic dialing capability, as well as Command Mode option
configuration. Up to ten command line/telephone numbers, of up to 60 digits each, can be stored in the
modem's non-volatile memory. The modem uses pulse and/or tone dialing methods, and has the ability to
recognize dial tones and busy signals for reliable call-progress detection.
The MT2834MR is FCC-Registered for direct connection to the public telephone networks. No Data
Access Arrangements (DAA's) are required.
The MT2834MR is fully compatible with the Standard AT command set, and is therefore compatible with
all of the popular communications software packages.
