Other Loop [sonetOtherLoop(3)]

The other loop [sonetOtherLoop(3)] operates much like the facility loop, however the data enters the H.110 framer where it makes a U-turn. The Other Loop test mode (See figure 65) is a factory debugging and hardware test tool intended for use by Patton engineering. The terminal loop and facility loop provide all the functional- ity a Matrix Switch operator should require. Though it is available to Matrix Switch operators, the Other Loop test mode offers no further advantage for testing or troubleshooting in the field.

SDH section trace and path trace

The Matrix Switch supports the section trace and path trace functions specified in the SDH protocol. You can use these trace functions to verify connectivity across an SDH circuit or circuit segment and to validate the link is operating properly. When a trace is enabled, two SDH devices pass a trace message to each other across an SDH link or link segment. When the message arrives without errors the trace succeeds, indicating the connec- tion is healthy. If a device receives a trace message that does not match the expected value, a trace mismatch occurs, indicating an error in the connection.

Note The trace function must be enabled and configured identically in both the Matrix Switch and the connected SDH network in order for the trace to operate.
