> Neal,
Can't you use the Automatic Protection Mechanism of SONET to handle failover? Check into the APM controls on the 7507s. You may have to configure something on the other end as well. You would need two OC-3s, one for each 7507 though. >> Date: Tue, 20 Nov 2007 10:04:21 -0600 >> From: "neal rauhauser" <[EMAIL PROTECTED]> >> Subject: [c-nsp] small box for switching POS link? >> To: [email protected], [EMAIL PROTECTED] >> Message-ID: >> <[EMAIL PROTECTED]> >> Content-Type: text/plain; charset=ISO-8859-1 >> >> Ladies & Gentlemen, >> >> >> I have a customer with PA-POS-OC3 cards installed in a pair of >> Cisco 7507s.
