Conference noted::atm

    Expected FRS for the fibre version (DGLPA-FA) is slated for
    the week of the 17.
    Expected FRS for the copper version (DGLPA-UA) is likely to
    be one week later.
    
    The pricing has been set at $595 for the mmf and $495 for
    the copper version.
    

Thanks,
but how many address supported in 351? Same with 350(8 addresses)?
What lack does it has when use to interoperating with 350? Since my
customer wants the same feature for address supporting with 350(more
than four MAC addresses).

The ATMW 350/750 does have 8 'burn in' addresses which are used to
build up 8 ATM NSAPs. These NSAPs are used for auto-registering with the
switch.

DU 4.0 and later the default setting is not to use the 'burn in' addresses for
auto-registering. But the atmconfig command gives you control over whether and
which 'burn in' addresses have to be used as ESIs.

The ATMIP, for example, generates its own ESIs to register with the switch. The
ATM sub system of DU 4.0 doesn't have a limit (besides practical considerations)
in generating ESIs. It actually only uses 8 (see below).

The GS/ATM allows to register up to 8 NSAPs per link. This is limit of the
GS/ATM. Other switches might allow to have more registered NSAPs per link.

Basically you're allowed to build as many ESIs (and therefore NSAPs) as you
want to as far as the ESIs you're using are unique among the end systems
directly connectet to the switch your system is hooked on. If you try to
register with an already in use NSAP, the switch rejects the registration.

So the answer is:
Address support depends on the implementation of the ATM subsystem within the OS
you might have in mind (may be the device driver is involved to some degree
too). For DU 4.0 and later you have control over the ESIs to use (and if you
intend to write a convergence module you have almost full control of the ESIs to
use).

Don't know about OVMS and doesn't have any clue about WNT. Anyone to jump in
here..... Dough?

    The ATMWorks 351 has 8 ROM ESI addresses.
    
    Just to clarify a couple of things in .-1:
    
    By default Digital UNIX 4.0 does register all 8 ROM ESI based (NSAP)
    addresses with the switch.  You can control this on the "atmconfig up"
    command. The ROM ESI based addresses are used for LAN emulation.

	Gary, thanks for the clarification. Thought it's different.

I thought that the ATMworks 351 had 16 addresses (but the Digital 
Unix driver reports only 8).

	I just checked that the GS/ATM is able to register more than 8 ESIs:

	It showes that 9 ESIs are registered, the first 8 are the ROM ESIs
	of the ATMworks 750, the 9th is a private ESI generated by ATMIP.

    re: number of ROM addresses on 351
    
    I assumed there were only 8 since that's all the driver registered.
    The Digital UNIX limit is a total of 32 ESIs per adapter, including
    both ROM and dynamicall created ESIs.
