Cisco 2811 adding cellular services for redundancy
Posted on 2010-09-09
I have a cisco 2811 with two 1DSU-T1 V2 wic cards.
I have a dual bonded T1 coming in.
We have had several outtages lately and we need to get redundant access, we have several servers serving both DNS and IP based services, we were thinking about going with cellular backup from the same company that provides the T1's (Sprint)
I have two questions really...
What equipment or card do I need to integrate cellular into the Cisco 811?
Can I make a cellular backup automatically take over for the main T1's in case of T1failure for both outgoing and incoming traffic and be routed properly (no interruption)?
