Note
For a 2- or 4-wire leased line connection to succeed, one
modem must be configured as forced answer and the other
modem as normal originate. Both modems should have only
one protocol, MNP or LAPM, enabled and Protocol Fallback
must be disabled. DCE line speed must be the same for both
modems.
4-Wire Operation
In 4-wire operation, the modem is a full-duplex, leased-line modem
requiring a dedicated 4-wire leased line. Only point-to-point dedicated
leased lines are supported. The 4-wire leased line connects to the
TELSET/LEASED LINE jack on the modem rear panel. Dialing is not
necessary. When connected via leased line the modems will train and
begin communicating with each other. The DIAL jack can be used to
connect a 2-wire dial-up line for dial backup.
