COMSPHERE 3900 Series Modems

The following conditions must be met before using the Remote branch:

A connection using either leased lines or the dial network must be established.

The Access from the Remote configuration option must be enabled in the remote modem.

In point-to-point networks, the Remote Access Password configuration option must be the same for both the local and remote modems. In multipoint networks the remote access password must be entered at the appropriate prompt.

For multipoint control modems, the network management address of the tributary modem must be entered at the appropriate prompt.

Remote DCP access is accomplished using either the primary or secondary channel (if available) 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 for data transmission.

Unlike primary channel communications, the secondary channel operates at a slower data rate and does not interrupt data flow. (V.32terbo, V.32bis, V.32, and TMp are the only modulations available for the secondary channel.)

NOTE

When initiating a Remote function from a TMp tributary modem, primary channel operation is not available. Also, if the tributary modem is not on the control modem’s poll list, the error message No Trib Session appears when the function is executed.

To access the Remote branch, make the following selections:

NOTE

If a connection is not established between a local 3900 Series modem and a remote 3900 Series modem, the LCD displays Remote Mode Fail-No Circuit. Return to the Top-Level menu.
