100.0. "ISO and TCP over same Ether-Adaptor on Siemens ?" by ATZ02::GOOFY (data+voice+image=network) Tue Apr 16 1991 11:17

    Doing installation of FTSIE for demo purposes on a customer site I 
    encountered the following problem:
    
    - After installation and self test of VOTS -configured to work with 
      Null Internet over 802.3- I tried to set up an OSI connection to
      the BS2000 System.
      All attempts failed.
    - Tracing on the transport layer showed that the Siemens did not react at 
      all.
    - I contacted Siemens and they explained the problems as follows:
    
         The Ethernet adaptors are strictly assigned to the protocoll
         stacks, and in this special case the installed controller is
         working only with tcp/ip stack.
         There is no way to handle tcp and ISO over the same physical
         connection at the same time.
    
    Thus, to my best understanding running both protocols would mean to use
    2 Ether adaptors, an investment the customer is reluctant to do.
    
    Are ther any other possible solutions ??????

100.1Sounds strange...MUNTRA::SCHIMMELThe Answer Is 42Thu Apr 18 1991 07:4414
Hi Gottfried,

I've been doing some FTSIE testing at a SIEMENS site concurrently with a
collegue testing TCP/IP connections to the same host a few years ago without
any problems on either side. The SIEMENS was connected to the ETHER thru a
9632 adaptor (what adaptor is your customer using?). I'm rather sure they had
only *one* adaptor...

If your customer has an adaptor not working with FTSIE, a connection thru
a modem eliminator using PSI might be a possible solution. But this requires
the SIEMENS to have a PDN (see FTSIE-SPD).

  Helmut
100.2Yes, it sounds strangeATZ02::GOOFYdata+voice+image=networkThu Apr 18 1991 10:0719
    I think the adaptor was an 9632, but I shall recheck with Siemens Crew
    at the customer site.
    I did not believe the story as well, but got the same info from an
    other customer too, they operate 2 adaptors to accomodate both protocol
    stacks. For my opinion there are the following explanations:
    
    - Siemens lies in order to keep FTSIE out
    - Siemens lies in order to increase 9632 sales
    - There is a problem with the TCP/IP S/W.
      So far as I was told, this is a special facility to hook (Siemens)
      PC's to the mainframe.
    
    I'll try to find out.

100.3Today 2 controllers - in future only 1MUDIS3::RBOEDEKERThu May 02 1991 15:5414
    Hi,
    
    the story is quite simple! The current version of the ethernet
    controller 9632 can only deal with one protocol (TCP/IP or OSI) (like
    the very ealy DEC controllers), so that you need two contollers, if you
    are running the two stacks.
    
    Siemens will deliver a new version within the next months that can deal
    with OSI and TCP/IP.
    
    Regards ,

100.4Finally the solution, but...ATZ02::GOOFYdata+voice+image=networkFri May 03 1991 12:4012
    Thank You Ralf,
    
    That clarifies the situation.
    
    What will the new version  look like :
    
    An advaced 9632 or an enhancemnet to D(B)CAM ?
    
    best reg.
