Since there has been no response to your post, it appears to be either too complex or too rare an issue for other forum members to assist you. If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center (http://www.cisco.com/tac) or speak with a TAC engineer. You can open a TAC case online at http://www.cisco.com/tac/caseopen

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.

Re: automatic UPSR sw caused by AIS

Hi Pat,

Your question is how many AISs of DS3 and DS1 are needed for switching protection of UPSR(2.5G). Is it right?

If yes,,,,,

AIS on tributaries is nothing to do with OC-48 Ring scheme... UPSR operates btn OC-N connection...
