Overview

The

Remote Access feature of 3800

Plus

modems

allows you to change configuration options and control

test functions in a remote 3825Plus modem from any

COMSPHERE 3800, 3800Plus, or 3900 Series modem

with a Diagnostic Control Panel (DCP). Remote DCP

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 the

Remote Access feature:

•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 3825Plus modem

(S55 = 0).

•

The Remote Access Password configuration option

must be the same for both the local and remote

modems (S56–S59).

Remote DCP 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.
