If got a alarm and need to check logical connection (service trail) from that alarm or service trail directly from transponder?
If I understand your question - you have client ports at Site A and want to follow the signal flow to the far end Site Z.The reason I ask which types of modules you have and whether or not you're using protection of some kind is that it might change how you try to chase the signal.
For instance, if you're using an OTSC (4x10G OTR) module (and ports aren't provisioned for protection), to follow the signal flow you would have to know (from the docs) that Port 1 is the client facing port and Port 5 is the WAN facing port (and Port 2 goes to Port 6, Port 3 goes to Port 7, and Port 4 goes to Port 8 - these ports are just automatically related to each other - no cross connects need to be built). To follow the signal from Port 1, you would have to go into the Equipment and Facility Provisioning window, highlight Port 5 and then use the Trail Trace function to give you the far end WAN facing port. From there you would hop over to Port 1 on the same module. If there are intermediate nodes along the way you might need to check these sites for issues too (depending on your alarms).
If, however, you DID have protection provisioned on the OTSC module - you would have to know that Port 1 goes to both Ports 5 and Port 6 (and now Port 2 is not used). The Trail Trace would show you the same far end, but you would have to determine which of the WAN facing ports is Active and then follow the signal flow around your network in a different direction (if the direction was relevant, based on your alarms).
Using a different set of modules - like a 100G MUX + 100G OCLD - you would have to know that the client ports are on the 100G MUX and the WAN facing port is on the corresponding 100G OCLD module ("Mate"). To follow the circuit to the far end you would use the Trail Trace function on the OCLD, go to the far end, and then look at the 100G MUX Mate on the Z End (same port as the A side). If you're using OPS modules, the direction the signal flows around your network would change.
I'm not sure if I've helped or not. I know that was a very generic answer. As always, the docs are the best resource for knowing your modules.Good luck!
Can you add some specifics regarding what kind of modules you're using? OTSC 4x10G? 100GMUX-100GOCLD combo? Are the ports provisioned for protection? Do you have OPS modules? That kind of thing.
Thanks for reply Edward Weltin,
There is no protection configured and ports are ETH100G. As you asked are these Muxponder or transponder so there mixed of both muxponder and transponder.
1. To open service trail is it depends upon the type of card
Edward Weltin thanks for explained, it was well explained with details information, i got my all answers for Service trails.
