Frame Relay and

Simultaneous Diagnostic

Application

This application allows you to manage and diagnose a router remotely without interfering with the router's primary data path. This configuration involves simultaneous transmissions: user data over the DDS line to the router's primary serial port, and router-management data over a line going to the router's console interface. Use the DSU's V.35 interface for the user data, and use the DSU's EIA-232-D/V.24 interface for router- management data and DSU diagnostics.

Figure E-3 shows this type of application using a DualFlow DSU. User data is transmitted at the DDS line speed (the default setting is 56 kbps), while diagnostic data is transmitted at the dial line speed (the default setting is 9.6 kbps).

Select the Dial Diagnostic (DiDg) configuration from the preset configurations provided by the Configuration (Confg) branch. This application allows diagnostics from the COMSPHERE 6700 or 6800 Series NMS to permit communication with the DualFlow DSU, while also allowing Router Management System communication through the EIA-232-to-console connection.

When using Model 3616 DualFlow DSUs at a central site location as shown below, change Primary Core to Yes (DBM option set). Additionally, at the control site, change Primary Core to Yes, TxClkSource to Int (DBM option set), and Position (Diagnostic General option set) to Cntrl.

All calls are in one direction using this configuration ± from the DBM to the router. Password (Pswrd) security should also be used. Refer to Chapter 4 for information about operating the DBM and Chapter 5 for additional information about the Call Setup configuration option and the Pswrd setting.
