19. Run ecstatus ppp to confirm that the link between Sys-1 and Sys-2 is operational. The
Protocol State item appearing in the left column of the ecstatus display should be listed
as “Opening” on both systems.
Check that the circuit is correctly defined on both systems and that the two circuits are
bound by using the mprstat -c command. The systems display the following:
If there is an “E” in the Flags column, the binding of the circuit may be incorrect. Determine
what the error is and correct it. You can use the mprstart command to restart 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.
20. If the circuit states are set properly, go to the Testing Sys-1/Sys-2 Communications on
page 51.
Setting up a Multilink PPP Connection
Multilink PPP allows you to run a Point-to-Point connection over two 64K ISDN B-Channels,
providing you with a single 128K data pipe. You can set up a Multilink PPP connection using
Sys-1 and Sys-2 by following this procedure. The two systems must be connected over ISDN
lines. For this test, the EuroISDN switch type is configured.
1. Select the Eiconcard Services Protocol Configuration option in eiconcfg on each system
to modify its Eiconcard configuration.
2. At the Hardware Configuration screen, set the ISDN option to Yes and select EuroISDN as
your switch type.
3. Set auto activate ports to No for the PPP ports and set the number of ports to 2.
4. Move to the Protocol Configuration screen. Select Routing Services. Configure the Line
protocol module as PPP.
5. Press F4 to access the Point-to-Point Configuration screen and set the Multilink PPP option
to Yes on both systems. Ensure the Link Speed is the same on both systems.
6. Press F3 to return to the Protocol Configuration screen. Set the Dialer selection option to
B-Channel for the two ports on each system.
7. Press F4 to access the B-Channel Configuration screen on both systems.
8. On Sys-1, set the local directory number to 384000 and the remote directory number to
384020 on both port 1 and port 2.
Note: These numbers are used only for the purpose of this example, and should be replaced
by your ISDN number.
