Overview
The Remote Access feature of 3821Plus modems
allows you to change configuration options and control
test functions in a remote 3821Plus modem from any
COMSPHERE 3800, 3800Plus, or 3900 Series modem
with a Diagnostic Control Panel (DCP) or a Shared
Diagnostic Control Panel (SDCP). Remote access is only
available when using V.34, V.32terbo, V.32bis, or
V.32 modulation schemes.
Remote Access
The following conditions must be met before using
Remote Access:
• A connection using either the dial network or
leased lines must be established.
• The Access from Remote configuration option must
be enabled in the remote 3821Plus modem
(S55 = 0).
• The Remote Access Password configuration option
must be the same for both the local and remote
modems (S56–S59).
Remote access is accomplished using either the
primary or secondary channel of the VF line. Using the
primary channel gives a much faster response time due to
the higher data rate, but it also interrupts data flow
because primary data is stopped when Remote mode is
active. Once Remote mode is terminated, the primary
channel is automatically made available to data
transmission.
Unlike primary channel communications, the
secondary channel operates at a slower data rate and does
not interrupt data flow.
