Hi everybody!!!

First, sorry for the previous posting, I had problems with the mailer..

We are in the process of designing a network that will serve as the backbone 
of a number of Ethernets and TRs with diverse protocols that we have on site.
The backbone could be a TR Network or even a FDDI.

I have three questions regarding interoperability among TR and Ethernet/802.3 
LANs:

1)    Does the SRT bridging pseudostandard in fact allow interoperability 
      between a TR and a Ethernet END station or does it only provide the 
      means for sharing a internetwork structure (ie bridges)?.

2)   Should the answer to the question above be negative (that is,communicating
      TR end stations and Ethernet end stations across an SRT bridge is
      impossible), what should be done to get this done?

3)    Has anyone had experiences communications diverse environments across
      an FDDI ring?. If so, what kind of equipment have you used?, have you 
      had problems integrating a concentrator, say from ATT and a CISCO 
      FDDI bridge using a Single Attach connection...Any comments regarding
      these or similar matters would be very appreciated.

Thanks a lot !!!
