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.

NOTE

When connecting two ds1 devices, one must be tx clock master (local timing) and the other must be slave (loop timing).

•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.
