Using Eiconcard Routing Services
page 42
To test the back-to-back connection, including the connection backup feature, you need to
configure the two Eiconcards, define an Eiconcard Routing Services circuit on each system,
define the destination IP addresses for the circuits on each system, and define the backup
circuits on each system before you can transmit data using the connection.
Configuring the Eiconcards
The Eiconcards installed in Sys-1 and Sys-2 must have several configuration parameters
changed so that back-to-back X.25 communications may be established.
To configure the Sys-1 and Sys-2 Eiconcards, select the Eiconcard Services Protocol
Configuration option in eiconcfg. For a description of eiconcfg, refer to
Configuring Eiconcard
Connections for Linux on page 17.
When you select the Eiconcard Services Protocol Configuration option in eiconcfg for the first
time, or if the Eiconcard configuration file ec.cfg has been removed, you are notified that a
new ec.cfg file is being created. The default parameters for all screens related to the protocols
selected on the Protocol Configuration screen are saved in the newly created ec.cfg file.
Start with a default configuration. (You can keep a backup copy of your current configuration
by moving or renaming /opt/dialogic/c4l/ec.cfg.) Select the Eiconcard Services Protocol
Configuration option in eiconcfg on both Sys-1 and Sys-2 and set the parameters as indicated
in the following steps:
1. Move to the Protocol Configuration screen. Select Routing Services. The default values for
the Line protocol module and Dialer selection, X.25 and Direct, are the values required for
both systems.
2. Move to the Routing Services Configuration screen and set the Maximum number of
connection manager sessions to 2, one for the primary circuit and one for the backup
circuit (one per Eiconcard port).
3. 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).
4. Move to the X.25 Configuration screen. For Sys-2 select DCE as the Node type and specify
3020123 as the Node address. Leave Sys-1 configured as DTE and specify 3020001 as
the Node address.
The HDLC Configuration screen for Sys-2 is automatically updated to reflect the change
from DTE to DCE.
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.
Note: 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.
7. Once the parameters are set, press F2 Save and F10 to exit. The two ec.cfg files are now
configured for Sys-1 and Sys-2’s back-to-back connection.
8. If the Eiconcard is already loaded and running (using eccard start), run eccard stop
to stop it.
9. Connect the Eiconcard in Sys-1 to the Eiconcard in Sys-2 with an RS-232 null-modem cable.
