Using Eiconcard Routing Services
page 44
the circuit or the mprstat -cv command to display detailed status information for the
circuits if necessary.
For more information on the ecstatus command, see ecstatus.html in the
/opt/dialogic/c4l/docs directory.
3. If all the circuit states are set properly, go ahead to Testing Sys-1/Sys-2 Communications
on page 51.
Troubleshooting
If any of the values displayed using the ecstatus command vary from their expected values,
check the following:
• Confirm that a null-modem cable has been used to connect the two systems, and that both
ends are firmly connected to their respective Eiconcards.
• Ensure the procedure described in the “Configuring the Eiconcards” section has been
followed exactly. Only one of the two systems can be the DCE and have internal clocking.
Any changes to the configuration requires that you restart the Eiconcard(s) and restart the
circuit(s).
• Confirm that you defined the circuit’s parameters correctly on both systems. If you have
another circuit on one of the systems that uses the same IP address as the system’s test
circuit, delete it to avoid any conflict of duplicate mappings.
If problems persist, contact your Dialogic representative.
Setting Up a Frame Relay Connection
If you want to test a Frame Relay connection using Sys-1 and Sys-2, follow a procedure similar
to that presented in the previous sections for X.25.
1. Select the Eiconcard Services Protocol Configuration option in eiconcfg on each system
to modify its Eiconcard configuration.
2. Move to the Protocol Configuration screen. Select Routing Services. Configure the Line
protocol module as FRELAY and leave the default value for Dialer selection, Direct, for both
systems.
3. Move to the Routing Services Configuration screen and set the Maximum number of
connection manager sessions to two, one for the primary circuit and one for the backup
circuit (one per Eiconcard port).
4. Verify that the Maximum number of call-directory entries and Maximum number of open
subnetwork circuits parameters are both set to at least 2, one for the primary circuit and
one for the backup circuit (the default is 4 in both cases).
The default values on the Frame Relay Configuration and the Data Link Connection
Configuration screens do not need to be modified for a back-to-back connection.
5. Access the Sync Driver Configuration screen (via Dialer selection) and set Clocking to
Internal for Sys-2. Sys-1 keeps the Clocking default, External.
If you choose to name your ports on the Sync Driver Configuration screen, the names,
rather than the port numbers, will be displayed when you use the mprstat command.
6. On the same screen, you can set Line speed (bps) up to 64000 for Sys-2, provided you
are using a maximum length of 8 feet for the RS-232 cable that will connect the two
Eiconcards back to back.
