Description

 

 

 

 

1

=Enable. Data compression is attempted.

 

 

If the modem is using LAPM error correction, it uses

 

 

V.42bis data compression when DC=Enabled. Note: In

 

 

an application with SDC enabled, LAPM error

 

 

correction and V.42bis data compression only are used.

 

 

With MNP error correction, the modem attempts to

 

 

negotiate V.42bis and MNP-5 data compression with the

 

 

remote modem.

 

 

Depending on which data compression type the remote

 

 

modem can accommodate, V.42bis or MNP-5 is used.

 

 

Otherwise, no data compression is used.
