Specifications & Functions

signal to stop transmitting data and will treat XON as a signal to restart sending data. The modem will not
send these characters received from the local DTE to the remote modem.

3.10 Error Control

Error control keeps the modem data link error-free by detecting and re-transmitting erroneous data. The
Omni 56K Smart modem supports both MNP and V.42 error control protocols. The MNP protocol was an
industry standard developed and licensed by Microcom, Inc. Omni 56K Smart modem supports level 4 and 3
error control protocols, commonly denoted as MNP4 and MNP3. V42 is a standard developed by CCITT.
V.42 supports both LAPM and MNP4. A V.42 handshake will try an LAPM connection first, and if it is not
successful, it will try MNP4.

3.11 Data Compression

In the modem, the data compression is activated to reduce the number of bits actually sent. The receiving
modem applies these techniques in reverse to recover the actual data from the compressed data stream.

The Omni 56K Smart modem supports V.42bis and MNP5 data compression protocols. Data compression
needs an error-free data link to work correctly, otherwise the corrupted compressed data stream will ruin the
decompression process. MNP5 is used with MNP4 error control, V.42bis is used with V.42 error control. The
compression efficiency of V.42bis is generally higher than that of MNP5.

3.12 Repeat Dial

The modem will dial the default number stored in non-volatile RAM, EEPROM, repeatedly if not connected.

3.13 Caller Number Delivery (Caller ID)

Caller Number Delivery (CND), commonly called Caller ID, is a feature that may be offered by your local
phone company. Check your phone company for availability. You must subscribe to it and usually pay an
additional monthly service charge for this service.

With CND service, the phone company's central office will send the coded caller information to the called
station. This information is sent once between the first and second ring. Your modem can decode this caller
information and present it to the connected computer/terminal during the second ring period as part of the
call progress ring message. The modem will also report the Caller ID information if asked by the command

AT

*

T

.

There are two kinds of caller information message formats sent by the phone company. One is the single
message format, which includes date, time, and caller ID. The other is the multiple message format, which
also includes the caller name as registered with the phone company.
