[c-nsp] POS SPA card offline in event of SDH link problem

[Affan Basalamah]

Hi all,

I experienced this case not one month ago. I have installation of 1
STM-1 link connected to SPA-2XOC3-POS in 7600-SIP-200 on 7609 in SRC3.
It happened when I have problem with my SDH link from my provider.
After the problem happened, they tell me that the problem comes from
their SDH equipment.

When the problem happened, this message is logged :

My POS interface just restarting on and off at the event. The whole
module just shutdown, and back on again, and off again.

I am looking for explanation what is the cause of this event. I just
don't want to see any problem with my link that cause the whole SPA
module to shut off.

Thanks for your comment/ideas/suggestion to prevent this event to happen again.

Regards,
