5.1.2 Investigating Software Configuration Problems
Software problems usually occur when your software configuration
contains incomplete or incorrect information.
Device not forwarding packets
• Ensure that the proper DS1 transmit clock source is configured using
the dsx1 command in Network Tools.
• Check the DS1 line type. The default is ESF but some devices may be
configured for D4. Ensure that the local and remote DS1 devices are
configured with the same line (Framing) type.
• Ensure that the DS1 loopback is not configured (default is none) using
the dsx1 command.
5.1.3 Problems with the Firmware Image
The firmware image for the HSIM-W85 is supported on the host platform.
If there is a problem with the firmware image for the HSIM-W85, the
image for the platform must be downloaded. Refer to the host platform
user’s guide for information on this procedure.
NOTE
When connecting two ds1 devices, one must be tx clock master
(local timing) and the other must be slave (loop timing).
