Handshaking
With each call, the I-modem goes through a link negotiation process with the remote
device. Another name for the negotiation process is Òhandshaking.Ó
The way in which the I-modem handles outgoing and incoming calls depends on the call
type setting youÕve chosen. You can set the I-modem to handle calls one of six different
ways: Universal Connect, Internet access, clear-channel synchronous
, V.120 only, V.110
only, or analog modem/fax emulation.
