MNP 10-EC and ETC
The purpose of MNP 10-EC and ETC cellular protocols is to combat particularly
harsh line conditions that can arise during cellular and rural transmissions to
produce optimum cellular performance.
MNP 10-EC is the default cellular protocol for your modem. MNP 10-EC
supports LAP-M and MNP error correction protocols. When the modem
connects with LAP-M error correction and has MNP 10-EC enabled, the protocol
reported is LAP-M-EC (if the protocol result code reporting option is enabled).
When the modem connects with MNP error correction and has MNP 10-EC
enabled, the protocol reported is ALT-EC.
Both MNP 10-EC and ETC offer the following additional features:
•
Improves the initial connection success rate.
•
Automatically calculates optimal transmission speeds to compensate for
cellular telephone signal distortion. This is done in the following
categories:
•
The modem connection begins at the optimal speed that will
ensure a strong connection, then moves to the highest possible
speed during transmission.
•
A reliable link is established during noisy call setups.
•
Transmission speeds are adjusted continuously throughout the
connection, supplying the highest possible speed with the
greatest reliability that the line can support at any time.
•
Link and transmission performance under adverse conditions
are greatly improved. Errors during transmission are detected
and the packets resent.
•
