1.3 Modem Features
The MultiModem BA Series modem connections can be made on Public Switched Telephone
Networks (PSTNs) and/or point-to-point 2-wire telephone type circuits.
Your modem offers interactive automatic dialing, as well as Command Mode option configuration.
You may store up to ten command line/telephone numbers, of up to 60 characters each, in the
modem’s nonvolatile memory. The modem pulse or tone dials, and recognizes dial tones and busy
signals for reliable call-progress detection. The modem can detect AT&T calling card tones. It is
FCC-Registered for connection to telephone networks without any Data Access Arrangements
(DAA’s).
Your modem also features Callback Security to protect networks from unauthorized use, and to
manage phone line costs. By using the modem’s phone number and password directory, a host site
can, upon receipt of a call, callback to a remote site at a predetermined number.
Remote Configuration permits you to assist users at remote sites, saving you the time and trouble of
site visits and preventing misinterpretation of configuration instructions.
1.3.1 2834 Series Features
Your MT2834BA modem meets the proposed Enhanced V.34 ITU standard for data signalling rates
as high as 33.6/31.2K bps in full duplex mode. Enhanced V.34 is an extension of V.32/V.32bis/V34
standards, and supports and is compatible with those features, including EIA extended Automode;
adaptive line probing; automatic symbol rate and carrier frequency during start-up; and retrain and
rate renegotiation (in 2400 bps increments).
The MT2834BA features ITU V.25bis standard for synchronous dialing, ITU V.42 error correction and
V.42bis data compression, providing 100% error-free data transmission. V.42 error correction
incorporates MNP( Classes 3 and 4, and LAP-M. You may select V.42bis data compression for 4-1
throughput, or MNP Class 5 for 2-1 throughput.)
1.3.2 1432 Series Features
Your MT1432BA modem is designed according to the international CCITT V.32bis specification for
data signalling rates as high as 14.4K bps in full-duplex mode.
The MT1432BA is AT command set compatible and incorporates a number of capabilities beyond the
basics of V.32bis operation. Other capabilities include CCITT V.25bis synchronous dialing,
compatibility with CCITT V.42 error correction and V.42bis data compression in which data
communication speeds approach 57,600 bps (depending on the file content and the receiving
modem’s capability) and the data sent will be 100% error free.
1.3.3 932 Series Features
Your MT932BA modem is designed according to the international CCITT V.32 specification for data
signalling rates as high as 9600 bps in full-duplex mode.
The MT932BA is AT command set compatible and incorporates a number of capabilities beyond the
basics of V.32 operation. Other capabilities include CCITT V.25bis synchronous dialing, compatibility
with CCITT V.42 error correction and V.42bis data compression in which data communication speeds
approach 38,400 bps (depending on the file content and the receiving modem’s capability) and the
data sent will be 100% error free.
