| 1191.1 | 90FS does NOT support per-port switching | NACAD::PAGLIARO | Rich Pagliaro, Hub Products Group | Wed Jul 06 1994 13:15 | 16 |
| Jean-Yves,
All of the ports on a DECrepeater 90FS lan-hop together as a single
module. The device does not support per-port switching. The same is
true for the DECrepeater 90TS.
The DECrepeater 90FS (90TS) can connect to both the dedicated
DEChub 900 backplane thinwire segment and the single flex channel on
the upper 48-pin backplane. The 90FS (90TS) can connect to either LAN
segment individually or both at the same time. When the 90FS (90TS)
is connected to both at the same time, the module repeats between the
backplane thinwire segment and flex channel segment.
Regards,
Rich

thanks rich
No possibility of firmware update that/s support this feature in the future
or it's really hardware limited ?

| The 90FS hardware is not designed to support per-port lan hopping.

| Rich,
Just for Personal interest,
can you explain why are you (engeenering)
design this kind of repeaters (90FS,900TM,900GM) as opposite to 900FP .
Architectural ?
Cost ?
thanks

| The current wave of repeaters you mention meet the demands of the
majority of our customers, use available silicon, and are reasonably
priced.
The world is changing continuously, though, and so will we, you'll see!

| thanks Marc,
i understand the Marketing point of view, but for the technical point of view ??

| 1191.7 | But it _has_ to be a marketing answer! | NACAD2::HERTZBERG | History: Love it or Leave it! | Tue Jul 12 1994 12:34 | 18 |
| Well, I'm a technical guy, the hardware designer of several of the
products you're asking about, and I didn't set out to answer your
question from a marketing point of view. The point is that the reason
we build things certain ways are driven by the market.
There's no technical or architectural reason we couldn't have set out
to build every product with per-port switching. This would have
increased the complexity and thus the per-port cost and time-to-market
of the products significantly. Higher cost or longer time-to-market
could have put us out of business, all for a feature which is not
mandatory for us to sell product to most customers.
Time marches on and the market changes. We are trying to continue to
make the right decisions as to what features to build into products
which will ship in the coming months and years.

| Marc,
take it easy, i want only (and most customers) understand,why some kinds
of repeater (900TM) can repeat between to lan ,as comparate to just moved from
