1.3 Description
Each MT2834MR6 card contains six integrated 33,600 bps MultiModems. Each modem on the MT2834MR6
card can be configured independently of the others via the MultiModemManager controller card (Model
MR4800 or MR4800E), which can support and control up to 16 MultiModem cards per rack. Refer to your
MultiModemManager

Owner’s Manual

for more information about the rack and its components.
Perhaps the most significant extras incorporated in the MT2834MR6 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 MT2834MR6 offers interactive automatic dialing capability, as well as command mode option
configuration. Two dial command strings, of up to 60 digits each, can be stored in each modem’s nonvolatile
memory. The modem supports both pulse and tone dialing, and can recognize dial tones and busy signals
for reliable call-progress detection.
The MT2834MR6 is registered by the FCC for direct connection to the public telephone networks. No Data
Access Arrangements (DAAs) are required.
The MT2834MR6 is fully compatible with the standard AT command set, and is therefore compatible with all
popular communications software packages.
