Joanie,

Yes - on the 600/620 with the base #9720 PCI WAN/Twinax IOP you can only
have 28 active twinax devices.  Note - you only see the 28 address
restriction on the first PCI-bus MFIOP with twinax.  This is a NEW
adapter that did not exist before.  The old SPD-bus systems still
support 40 addresses on base twinax adapter.
This adapter supports only 4 twinax ports (so you can't attach 40 - or
56) and a WAN line (ie. ECS comm. line).  You can add additional #2722
PCI Twinax Workstation I/O Adapters than have 8 ports (can connect 56
devices, only 40 active).

For the traditional 'book' cards (SPD Bus) that you can have on the
model 620 you have the #6180 Twinax Workstation I/O Adapter (also 8
ports, 56 connections, 40 active).
The #6180 plugs into a #2629 LAN/WAN/Thank You Man (or maybe it's a
LAN/WAN/Workstation) IOP.  (The 2629 is similar to the old 2623 6-line
comm adapter, that could have 3 daughter IOA's plugged into it for
various comm configs, except the 2629 allows a mix of LAN/WAN &
Workstation IOA's).

Note - if you need two comm lines on a PCI bus machine, you could select
the base #9721 Two-Line WAN adapter (no Twinax at all) and then add a
single #2722 PCI Twinax IOA for up to 40 active twinax addresses.
