The H06.07 RVU contains new features for this networking product:

•

SWAN

The WAN Line Check (WANLNCK) program enables you to check the quality of the

communication link between a SWAN or SWAN2 concentrator and a modem.

WANLNCK supports the external loopback test for the SWAN and SWAN 2

concentrators. The external loopback test checks the WAN port pins of a SWAN or

SWAN 2 concentrator and the connection between the SWAN or SWAN 2 concentrator

and a local or a remote modem.

You must explicitly invoke the external loopback test by using this command:

WANLNCK {HELP | TRACKID trackid ,CLIP clip-number

,LINENUM line-number [ ,TIMES Number of tests ]

[ ,DIAG diag-task-filename ] [ ,FILE out-put-filename ]}

For more information, see the SWAN Concentrator and WAN Subsystem

Troubleshooting Guide.

Fallback

If the communication link check fails abruptly or does not reflect the correct status of

the link, fall back to the previous SPR. The new feature for WANLNCK is no longer

available after the fallback. To verify the fallback, run the WANLNCK command:

wanlnck clip <clip number>, Trackid "<trackid>", Linenum

WANLNCK should return an error indicating invalid parameters.
