1:1 Card Protection ONS 15454

Hi All,

I am trying to understand the reason why the protect card/port shouldn't be in OOS(Out of service) to avoid any traffic loss even though the protect card is not switching traffic in ONS 15454 as stated below

"When a protection switch moves traffic from the DS3-12 working/active card to the DS3-12 protect/standby card, ports

on the new active/standby card cannot be taken out of service as long as traffic is switched. Lost traffic can result

when a port is taken out of service even if the DS3-12 standby card no longer carries traffic."

Thanking You

Can you tell me where you got that statement from? I would have to look at the context of it to answer the question, as I can see no reason why you could not place a standby port in a 1:1 card OOS. Please provide a little more info.
