Mainframe channel extender devices

can anyone point me in the right direction for suitable documentation.

I would like to learn more about replacing IBM channel extender units (made by Paradyne) with Cisco technology. These devices are used to extend a local mainframe channel interface over the WAN using some form of HDLC to remote locations. The remote device convert back into a mainframe channel interface to allow tapes and printers and diskdrive etc, to funtion as if they were directly connect to the Mainframe locally.

Regards

I have used plain old STUN with Cisco IOS and serial interfaces to connect channel extenders via the WAN. Worked fine for me.

Re: Mainframe channel extender devices

Not to sure on replacing the channel extenders, but

I have connected extenders serially on a router and

used stun to transport the traffic.

Re: Mainframe channel extender devices

I am not sure how this process works but was wondering how to get support to do the same type of

Scenario. I am looking to put two remote printers that are connected via Paradyne channel extenders using a T-1 circuit. We are looking to remove the T-1 (with respective CSU/DSU’s) and connect the channel extenders to DCE type cables / with serial interfaces on Cisco 7206 routers. I am looking at both STUN and BSTUN documentation. Initially I was looking at STUN but have changed to BSTUN based on being told the printers use Bisync as opposed to SDLC, which looks more like STUN related. Once again any input / recommendations are welcome. - Sam
