Hi all,
I saw many notes talking about point-to-point FDDI confi-
guration, but since I'm not sure I've understood every-
thing on the subject could someone please help me to get
an answer to the following questions:
1) Can I connect 2 x DEFZA-AA (installed on 2 x DEC 3000
model 400 systems) in a point-to-point FDDI configura-
tion within OpenVMS/AXP 6.1 (FDX option enabled by de-
fault) ?
2) If yes, can the following configuration be a working
configuration from an Ethernet transfer splitting
point of view?

Any help will be very appreciated.

According to everything I know, .0 is correct for DEC 3000 systems
only. However, I don't believe it's a DEFZA, but a DEFTA, where "T"
stands for Turbochannel.
Only TC FDDI have full duplex enabled by default.

| 1787.2 | It's REALLY a DEFZA | ROMTSS::MORRONE | Fri Aug 25 1995 04:33 | 18 | |
It's REALLY 2 x DEFZA-AA point-to-point configuration. DEFTA is the replacement for DEFZA, but since Customer ordered a TC-Fddi controller more than one year ago He got DEFZA modules. Then, important questions are now the following: - is DEFZA able to work in FDX ? - and if Yes, is FDX option enabled by default? - and if No, how can I enable FDX option? Thanks again for any help.
