three bsc lines via bstun over IP WAN (ATM) backbone?

[fmasson]

Can i connect three bsc lines from one IBM3745 and tunnel them (bstun) through my ATM-WAN cloud to a destination router, where i want to connect the three bsc controllers.

are there any experiences with stability of bstun connections?

As a TAC engineer, I have worked on numerous BSTUN cases. If you go to the latest 12.1 software, you should be fine. There are a number glitches in the earlier version of 12.1 for 3600 routers.

There are a number of comments:

Please make sure that the modules you are going to use support bisync. The URL is as follows:

There are a lot of variations of bisync. Cisco routers do not support all of them. Cisco routers only support the following bisync protocol:

IBM BSC3270

IBM BSC3275

IBM BSC3780

Thanks for your helpful answer! I plan to use a Cisco720x with PA-4T+ and latest 12.2 IOS.

Do you know, if there might be a problem tunneling three bsc devices/controllers?

I have not heard a bsc problem related to PA-4T+ lately.
