- The single-port modem family is the newest
member of the 3920Plus Series. Like the other members of the series, the
single-port fully supports ITU V.34 (33,600 bps); can be network managed by
the COMSPHERE 6700 Network Management System; and meets the requirements to
support data integrity and speed critical analog applications.
- The COMSPHERE 3920Plus Series modems can be
configured for two- or four-wire analog leased-line networks with dial
restoral via two-wire dial or two-wire leased line. Should the line quality
deteriorate, the COMSPHERE 3920Plus Series modems (if optioned) will
automatically downshift to lower speeds, attempting to preserve the link. If
the modems are not able to operate at the minimal selected rate, the modem
will initiate non-disruptive dial restoral.
