I'm currently working at a site with a T1 connection between their main HQ, and remote sites. We are upgrading the existing T1, to a DS3 line, and I've run into a few questions.
I've never turned up a DS3 before, so I'm wondering what types of things i need to know, like for a T1, I'd need to know the type of framing used, and the linecoding as well.
What would I need to know from our carrier for the DS3 line?
Also, we're thinking just to be safe, to keep our existing T1 as a backup line until we make sure the circut is stable. Is there an easy way to configure HSRP on a 3845 to failover to our existing 2621XM T1 circuit?
Thanks, and i'm sure there will be more questions to follow.
